By augmenting your conventional exercise selection by Fit Cuffs, you got access to an effective, convenient and significantly less time demanding workout.

In this video we got even more great exercises to the repertoire of low-practical BFR upper body exercises, you can do about everywhere and any time of the day:

0:02 Bodyweight Dip.

0:05 Leg Elevated Chest Press.

0:07 Reverse Flyers.

0:13 Dumbbell Chest Pres.

0:20 Seated Dumbbell Curls.

0:26 Added load by stacking a tire with dumbbells.

0:44 Upright Rows.

0:48 Standing Dumbbell Curls.

BFR can be relevant for athletes, gym rats, and not to forget, in musculoskeletal rehab where high-load may initially be contraindicated. Basically, BFR lets you become stronger, with less stress on the tendon and articular structures, which is relevant for periods of deloading or as a finisher after a conventional workout.

Both programming modalities can be equally as effective and during this time, with limited access to the gym, BFR is probably more pertinent than ever. But as presented in the previous two posts, with reference to the newest and relevant data, it seems appropriate, that BFR is primarily used as a finisher, or as a substitute for shorter periods (<4-6 weeks).

We especially recommend BFR as a part of a periodization programming, for individuals with high volumes of resistance training or for athletes with high intensity weightbearing activities. Simply applied as alternating weeks of either high-load training or low-load BFR training followed by weeks as a short finisher to a high-load training session.

In the past, we have presented the effect of BFR vs. conventional high-load training, but for practical applications, BFR is often more applicable as an add-on on.

This has been explored in a recent RCT from University of southern Denmark and in a practical research-based guide from Rolnick & Schoenfeld.

In the RCT, the researchers compared the effect of lower-limb block-structured training, consisting of alternating weeks of BFR training and conventional Heavy-Load resistance training (BFR+HL) vs. only (HL).

Methods: 18 active young participants were randomized to either 6-weeks (22 sessions) of structured training alternating weekly between BFR (20% 1RM) + HL (70-90% 1RM) vs. only HL (70-90% 1RM).

Outcomes. Maximal isometric knee extensor strength (MVC) and muscle biopsies (VL) as myofiber cross-sectional area (CSA), myonuclear (MN) number and satellite cell (SC) content.

Results: MVC increased in both groups (BFR+HL: +12%) vs. (HL: +7%). Type 2 CSA increased similarly in both groups (16%), while gains in type 1 CSA were only observed in HL (12%).

Conclusion: Conventional HL can periodically be replaced by low-load BFR without compromising gains in maximal muscle strength.

In the practical research-based guide, you will find an evidence-based recommendation on how to maximize hypertrophic potential with the implementation of BFR into a conventional program. .
From the comprehensive amount of original research on this topic, it seems legit to add 1–2 exercises per target muscle group at the end of a heavy-load training session, to preferentially stress type 1 muscle fibers as a “finisher”.

This perspective on muscle fiber differentiation seems valid as the authors have discovered this from at least 2 original research articles, but this is actually the direct opposite trend that was discovered in the RCT!

Any thoughts or explanation, as why the RCT found that only the conventional High Load group gained type 1 muscle fiber hypertrophy?

Secondly, what should be considered when choosing to either implement BFR as alternatingly weeks/days (the RCT) vs. supplement to conventional training as a finisher?

In this video we see a great circuit-based training presented by @curtis_demont as a selection of lower body exercises augmented by Fit Cuffs.

Exercises in display:
0:16 Walking Lunge
0:20 Squats Jump
0:27 Push-up
0:42 Inch Worm
0:39 Horizontal Jump Squat
0:49 Lateral shuffle

So, as long as the gym is closed, we advise you to utilize your favored BFR tool and move your exercise routine to urban areas, nature or for some higher restricted regions as home training.

But if you do not supplement your BFR training by any kind of external resistance tool, like elastic bands etc., most people need to consider how to fatigue of both type 1 and type 2 muscle fibers.

As a rule of thumb, to target type 1 muscle fibers, you need to train at lower intensities, but perform higher reps and probably also more sets.

Subsequently, you can also consider the force-velocity relationship like doing force-full movements like sub-maximal Squat Jumps to achieve the fatigue of type 2 fibers at a rapid rate. This is because, if exercises are conducted at higher velocity this leads to greater exhaustion of fatigue sensitive type 2 fibers.

Any thoughts or precautions on BFR in combination with higher velocity based exercises like Jumping?

In this post we present yet another set of low practical BFR exercises: . 0:00 Step Up. . 0:10 Romanian Deadlift. . 0:22 Squat. . 0:34 Kneeling Squat. . 0:44 Reverse Lunge. . During this point of time with many gyms being closed, it becomes inherently more interesting, whether BFR traning can substitute conventional high load traning? . It seems, that for most people it actually can be just as effective in regards to strength and muscle mass, but tendon health is a less explored field of research. . So, in a new pilot study from University of Copenhagen, the researchers have investigated whether BFR can help to improve tendon health in people with chronic Jumper’s knee (JS). . The rational for using BFR on this population, is that O2 deficiency in the muscle causes lactic acid, that seems to stimulate the formation of collagen protein in the tendon. . Protocol: 7 participants with chronic JP trained 6 sets of both single leg-press and single leg-extension at 30% 1RM until volitional failure for only 3 x 3/weekly. . Results: They experienced about as much progress as normally expected after 12 weeks of heavy slow resistance (HSR) training, which is the current recommended treatment for JS. E.g. significantly less pain (NRS) as a reduction of 50% during single-leg decline squat testing and ultrasound assessment of tendon, showed vascularity diminished by 31%. . Though, considering the small sample size and short duration of the BFR intervention, the results are only preliminary. . If we compare the present findings with the results from Centner et al. (2019), it seems valid that BFR training can be used as the primary modality in the rehabilitation of tendon related pains/disorders such as tendinopathy. But reversely, in comparison with data from Kubo et al. (2006), the BFR leg experienced no relevant change on the tendon level. As the BFR leg increased muscle strength and size, without the increment of tendon stiffness or force–elongation, but the high-load leg achieved the desirable tendon improvements. . Any thoughts on BFR as the primary training modality or treatment of chronic tendon disorders such as tendinopathy? . Source in the comments.

On this post we present yet another low practical setup with Fit Cuffs to be used for about everyone when gym access is limited. . For elderly or in rehab situations just BFR-walking can be demanding on both the cardiovasculature system and the peripheral musculature. . When climbing stairs home or outside, the possibilities for progression or regression are huge. So, by either changing the pace, step length or Range of Motion (ROM) the exercise becomes progressively more difficult. . As a rule of thumb for stair climbing, you should primarily progress the pace for improvement of aerobic capacity e.g. VO2max. For muscular adaptations we recommend to progress by skipping steps, as you got a larger ROM. By going into a lunge during ascending, the training stimuli shifts even more on the peripheral musculature because of the concecutive larger ROM and force vector principles. . Well-trained individuals have to climb at a high pace for cardiovascular and peripheral benefit, but by augmentation of Blood Flow Restriction (BFR-climbing) it becomes inherently more demanding. This has obviously benefit for improvement of performance in regards to muscle endurance, VO2max, etc. That is also why BFR-climbing can be beneficial at much lower pace, shorter step length or less need for external load. . For rehab or prehab these principles are probably even more applicable, this is if stair climbing either aggravate symptoms or higher impact is contraindicated, e.g. post-surgery. Because with BFR we can effectively use considerable less pace and step length compared with No-BFR stair-climbing, which equal less impact force. These basic principles can be real a gamechanger for chronic or acute ankle, knee, hip or spine injuries, but without attenuation of the corresponding effect. . Subsequently, is seems to have more profound benefit which is especially relevant for the elderly, as stair-climbing with or without BFR improves glycemic control and body composition. .

When everything are closed, we advise you to find the opportunity to move your exercise routine to urban areas, nature or for some restricted regions as home training. But when your local gym is not an option, you have to consider several factors for you to maintain muscle mass or strength.

For most gym rats it should be achievable to maintain muscle mass, but it becomes inherently more difficult when your goal is hypertrophy. In regards to absolute strength, it becomes even more difficult to retain and especially increase strength.

The amount of load and volume is obviously highly dependent on your current training status. But for a vast generalization, maintenance of muscle bulk should be obtainable for most people, especially with BFR and in less time!

As a proxy for estimation of 20-40% of 1 RM, these basic simple principles apply:
As rule of thumb, aim for 20-35 reps to voluntary failure for the first set, followed by 3 sets of 10-20 reps with an interset rest period of 30-45 s.

When considering the minimum effective volume, it becomes more difficult to generalize, but in regards to hypertrophy, more IS better! On the other hand, if your goal is to maintain strength, less volume is needed. Aim for at least 30 % 1 RM with every set near failure. Some evidence suggests that BFR can be optimized by exercising the same muscle group 1 or even 2 times a day in periods of 3 weeks.
Considering these principles for BFR, bodyweight squats is insufficient for most people, but can easily be progressed by means of:

External resistance with an elastic band ➡️ Unilateral like Bulgarian split squat ➡️ Higher relative pressure (mmHg).

For regression of push-ups, just elevate the hands relative to the feet as displayed.

Please also remember, that all exercise is better than no exercise! And BFR is Better For Results – when load is low!

This post is about our concurrent research on the reliability and validity of our new Bluetooth Device for assessment of Limb Occlusion Pressure (LOP). This is particularly relevant for Blood Flow Restriction (BFR) training and exercise. . The utility of the present research is beyond Fit Cuffs product selection, as this will have universal implications for osciliatory/ oscillometric blood pressure measurements for assessment of LOP, a potential valid alternative to hand-held dopplers. . We find this method to determine LOP highly interesting, as this is more assessable compared to the doppler-method, which is relevant for about everyone into BFR. . We truly appreciate everyone’s efforts and commitments to test our new Bluetooth Device. Without your practical and academic expertise this was not possible. This is greatly appreciated and we look forward to continuing our collaboration. . Especially thanks to Okan KAMİŞ & Mahdy El-Zein for the dedication that goes into this study: .

This post is about knee rehab with extensions to the progressive model for BFR proposed by Loenneke et al. (1). . It seems that passive BFR (BFR without exercise), has the potential to attenuate muscle loss during periods of immobilization (2). Though, for obvious reasons this application is inferior to active modalities. . For the initial stage post-surgery or in some chronic cases, joint swelling and symptoms can be triggered by even low load resistance training. This is especially in such cases that BFR cycling can be the key to regain muscle and mass strength (3). . In the BFR literature, it seems that both continues or interval training can be utilized for hypertrophy and muscle strength (4). But as the muscle specific adaptations seems superior for conventional high intensity training (HIIT) vs. continues, it seems coherent that this is also the case for BFR training. Thus, a single study actually discover the opposite trend (4). . The central paradigm of this ladder-principle, is the reverse nature of progression or regression for early stage rehab vs. prehab, respectively: . Conventional high-load resistance training → . ⬆️ Low-Load resistance BFR training, moderate pressure (mmHg) → . ⬆️ Very low-load resistance BFR training, high pressure (mmHg) → . ⬆️ High intensity interval BFR Cycling → . . ⬆️ Continuous cardiovascular BFR i.e. steady state walking or cycling → . . ⬆️ Passive BFR . As described above, we propose that this extended progressive model should be reversed for the general population. That is, if you are able to lift heavy without any pain, conventional exercise should be first line healthcare, but if this is not applicable regress one step, etc. . In the video, a woman with a total knee replacement is training with high intensity intervals for late stage rehab, as in her case, even very low-load training is associated with excessive joint swelling. .

This post is about relative loads (% of 1RM), relative blood flow restriction (% of LOP) and the potential of a minimum effective pressure for very low loads. . The default recommendation for upper body and lower body BFR exercise is to use at least 40% LOP and 50% LOP, respectively, for non-failure BFR protocols like the standard four sets of 30-15-15-15 reps. But because both BFR Stimuli and load contribute to the fatigue caused by BFR exercise, we must also consider relative load for a final recommendation (1,2): . Because higher blood flow restriction pressures are likely to be beneficial for muscle growth when very low loads are used (1), it turns out that simple bodyweight-based BFR exercises such as squats and lunges are sufficient to increase muscle mass and strength in active adults (3). . For practical applications, if the relative load is very low (10-15% 1RM), then it can be compensated by higher reps and using a higher pressure (1), as about >70% and >80% for upper and lower body, respectively. This is especially relevant for well-trained people who do not have the opportunity to hit the gym, because of travel, lack of time or simply just for convenience. . Reversely, the current data suggest little or no differences in muscle growth, muscle size or endurance in response to 40% vs. 90% LOP when using higher relative load (30% 1RM). But the 90% LOP condition produced higher ratings of perceived discomfort (2), which is counter productive for adherence to about any exercise program. . But as the data also suggests, that the combined effect of higher loads and higher pressures means less exercise volume, this might have some relevance. So, if you can withstand the high discomfort by combining higher pressure and load, aim for about four sets of about 30-10-10-10 reps (2). . As displayed in the video, a higher relative load (30-50% 1RM) is being used, but as a tradeoff, use less pressure (40% LOP) and maybe slightly longer inter-set rest (45s -1 min). .

This post is about the width and material properties of BFR cuffs and how this effect different physical parameters and perceived discomfort.

A newly published review on BFR and discomfort concludes that particularly for the upper body, narrower cuffs seems to be favorable as wider cuffs seems to increase discomfort during exercise (1). For the general public and healthcare this is of huge importance as the adherence to exercise or rehabilitation is imperative for effect regardless of goal setting.

Though, there is a range of tradeoffs or pros and cons to consider when choosing the right cuff width:

Narrow cuffs require higher absolute pressures to elicit the same relative pressure which can inhibit estimation of LOP and increase compression into the underlying tissue (2). The relative fluctuation of pressure and mechanical compression during muscle contractions is also larger.

On the other hand, narrow cuffs allow for more freedom of movement and even though the localized pressure is higher, a smaller area of the muscle is affected by this which seems of importance (1).

During the prolonged development of Fit Cuffs into it’s current form, the cuff material has also been discovered as extremely important especially for the upper body, Thus, the research has yet to confirm this point (3).

Since muscle contractions in the upper arm expands the girth relatively more compared to the upper leg, a stiff material is not alone discomfortable, but also hinders muscle contractions and in extreme cases can lead to tissue damage (1,2).

For a visualization of the inherent properties of different cuff material, see the figure from Mcewen & Casey (cuff type B vs C). This is also why Fit Cuffs is designed with differentiated properties with the upper body cuffs being more pliable.

This post is about the brand new Bluetooth Unit for measurement of Limb Occlusion Pressure (LOP) by means of Oscillatory Blood Pressure (BP) (1,2). . When assessing BP you should always use a calibrated cuff in terms of the width of the cuff relative to the circumference of the limb you are assessing. The recommended cuff width is 0.4 relative to the circumference of the limb (3). . That is why a standard BP cuff is about 14 cm wide, which is a calibrated cuff size relative to the upper arm for most adults. But if you are assessing BP on obese or bodybuilders, this would not be a valid measurement of BP, as in these cases you would need a wider cuff to avoid overestimating BP (4). The same principles apply for a very small upper arm, as you need to use a narrow cuff (4). . So even though measurement of BP is only valid when using a calibrated cuff, the amount of pressure to completely stop arterial blood flow is both valid and reliable (5). . Practical Application - how to find LOP via Bluetooth: . Connect the Unit with your phone via standard bluetooth tech. . Connect the Bluetooth Unit with the hose of the Fit Manometer, then connect the unit to the cuff. . Completely rest the corresponding limb and follow the displayed guide provided by the app. . After appropriate measurement you will find SYS (SBP) on the top left corner on the phone. This is the Limb Occlusion Pressure (LOP) for that limb in that particular position, just as the standard but prolonged method with a hand held doppler. . When preparing for exercise just detach the Bluetooth Unit and set the pressure relative to SYS (40-80%). . Research has shown that this method (oscillatory blood pressure measurement), is more precise compared to a hand held doppler ultrasound, relative to the golden standard i.e. invasive methods (5). . Our preliminary testing is showing a very good inter-rater reliability, by comparing this bluetooth device vs. LOP by hand held doppler, as a variance of only 3-6%. . Source in the comments. .

This post is about some relevant considerations for BFR in rehab. . First of all, there is no such thing as an optimal rehab regime, and secondly, optimal rehab must be individualized. No people are alike, the same goes for any injury, because of this an individual approach is always recommended. . Individual components such as daily activity, type of surgery, pain levels and not at least personal preference of exercises should be considered. But for most people or relevant stakeholders, the expected time to return to sport or daily activity is of high priority. . Especially in cases of load or weight bearing restrictions, the application of BFR is an effective way to attenuate muscle loss as a supplement to other rehab modalities, as this can accelerate muscle strength and function much earlier compared to a conventional rehab protocols. Though, as always consider the healing properties of subsequent tissues. . E.g. post ACL reconstruction, muscle strength and function can conceivably be reestablished at a higher rate than the remodelling properties of the transplanted tendon. But by following the guidelines and time for return to play, the inclusion of BFR can lead to greater functional symmetry (1) and probably higher estimated pre-injury capacity (2), which are both proven to lower the risk of reinjury. . In rare occasions there can be adverse side effects or other contra indications that inhibits the use of BFR, especially for early stage rehab (0-2 weeks post op.). That is why it is recommended to consult the surgeon before implementation of early stage BFR and always be aware of any additional swelling compared to other conventional exercises. . Conclusion: BFR should be used on the basis of an individual preference with consideration of physical components, such as healing properties of surrounding tissues and potential contra indications. .

The incidence of fractures in DK/year is approx. 80,000, of which 3,000-4,000 are ankle-related. . Most often, the fracture is plastered, which can include marrow sewing, osteosynthesis and rarely external fixation. For the first 3 weeks, load is inhibited, at approx. 3 weeks post op. gradually increased weight bearing is recommended. . Therefore, one should be careful about starting exercising, to avoid compromising the healing mechanisms of the bones. As adjacent to the fracture, muscles, arteries and nerves can be injured due to the sharp surfaces of the fracture or during the operation, which potentially complicates the rehab. . Because of the required immobilization following operation, severe muscle atrophy (muscle loss) will occur. As ankle fractures results in longer periods without weight bearing and local immobility, the rehabilitation options are very limited in the early phase. . Though, it has been proven that atrophy can be reduced by a swift implementation of BFR, in respect to fracture type and possible complications. By reducing the associated loss of muscle mass, one could expect a shorter rehab period and therefor a faster return-to-play. By combining BFR with conventional low-load resisted knee-extension and knee-flexion exercises you got an effective combo to counter act the atrophy of the thighs, hamstrings and the superficial calf muscles. . Considering the recommendation of high frequency training as 1-2 daily for an effective retention of muscle mass for, elastic bands are being used as a low practical setup for 3 consecutive weeks. . Adjacent to this, BFR may reduce the fracture associated pain (hypoanalgesic effect) and improve overall functioning which may translate to less long-term disability, which is especially relevant for the elderly. .

This post is about the effect of BFR Resistance Training (BFR-RT) on strength and muscle mass in comparison to Conventional Resistance Training (C-RT) or High Load Resistance Training (HL-RT). . Because of the inherent difficulties of a fair comparison, results are varying of wherever BFR-RT is more or less effective. Though, at least 4 meta-analysis has explored the potential effect of BFR-RT vs (C-RT) / (HL-RT). . But even though this has been explored in several metal-analysis, methodological difficulties make the question hard to answer without further clarification. . If we take a look at short term follow-up it seems that BFR-RT can be more effective, but probably only in regards to hypertrophy. For longer follow-up periods (>10 weeks) it seems that C-RT is more effective on most parameters. . But the largest issue for measuring the effect of BFR-RT, is the different group designs, i.e. type of exercise intervention. Therefore, we have tried to pin-point some relevant comparisons and the results extracted from various meta-analysis: . BFR-RT vs C-RT (repetition matched): Strength, significant in favor of BFR-RT. Hypertrophy, significant in favor of BFR-RT. Though much higher Ratings of Perceived Exertion for BFR-RT . BFR-RT vs C-RT (voluntary/repetition failure): Similar effects, thus in favor of BFR-RT. Similar Ratings of Perceived Exertion. But anywhere from 30-50% more repetition needed without BFR. . BFR-RT vs HL-RT (relative RM matched or voluntary failure): Strength, in favor of HL-RT. Hypertrophy, similar effect. Though, longer exercise duration for HL-RT. Similar Ratings of Perceived Exertion. . Summarized: Short-term muscle mass: Probably BFR-RT. Long-term muscle mass: Approximately same. Short-term muscle strength: Approximately same. Long-term muscle strength: HL-RT. Side note: Muscle endurance and anaerobic performance: BFR-RT. Maximum power development and training to improve running velocity: HL-RT. . But these comparisons have only limited practical importance as BFR-RT is primarily targeted the impaired e.g. injured or just as an adjunct to HL-RT for the majority of athletes and average Joe´s. .

In this post we present the interesting results from a yet another BFR-running RCT.

The present study explored the effects of interval running performed with or without BFR on different parameters of muscle physiology and performance.

Method: Sixteen participants randomized as either BFR or No-BFR for 8 running training sessions. Before and after training, subjects completed an incremental test to determine peak running velocity/maximal running speed maximal oxygen uptake “(VO2max)” and running economy, followed by a time to exhaustion run performed at peak running velocity.

Running training for both groups consisted of progressively increasing volumes of 30 s. intervals completed at 80% of their peak running velocity.

Results: Running economy only improved in the BFR group.

Peak running velocity improved in both groups with small but significant effect size of 0.31 in favor of BFR.

Incremental test time also increased in both groups with small but significant effect size ~0.3 in the BFR group.

Time to exhaustion run was also observed in both groups (27 ± 9% vs. 17 ± 6%) as a small but significant effect size ~ 0.3 in favor of BFR.

“VO2max” improved in both improved in both groups (6.3 ± 3.5 vs 4.0 ± 3.3%) with a trend for higher gains in the BFR group vs. No-BFR.

Conclusion: Running augmented by BFR seems to improve several parameters of performance. The beneficial adaptations after BFR-running are speculated to be primarily muscular rather than cardiovascular.

In the video @frederiksass has elastic band attached to his thighs for additional activation of the hip muscles, performed at a constant pace i.e. 20-30% of his peak running velocity.

We propose, that elastic band resistance combined with BFR-running to be just as beneficial compared to high velocity running, but evading the rapid fluctuation of pressure under the cuff during forceful strides.

In this post we present the results from a BFR-futsal RCT conducted on 12 elite futsal players.

The study combined futsal training with BFR and showed that the addition of BFR was superior to normal futsal training.

Aim: The effect of 3 weeks of BFR-Futsal on performance, strength and hormone levels.

Method: 12 players, 6 BFR-players vs. 6 No-BFR. 10 sessions as small sided games 3 vs. 3, 3 min futsal followed by 2 min rest for 4-8 intervals. BFR group had cuffs inflated to 110% of leg systolic blood pressure and further increased by 10% after every two completed sessions. Intensity 80–100 % HRmax in both groups.

Results: BFR-group had significantly greater improvements in peak torque knee extension (30.9 ± 8.0% vs. 14.9 ± 7.5%), flexion (23.8 ± 8.4% vs. 8.1 ± 5.7%), favorable serum concentration of myostatin and a trend for a greater improvement in a Futsal Special Performance Test. Though, Ratings of Perceived Exertion were higher in the BFR-group: (13–14 Borg) vs. (15-17 Borg).

Conclusion: The addition of BFR to futsal practice can enhance muscle activation, strength and hormonal responses. But please consider several limitations, e.g. sample size was fairly small.

Our recommendation regarding augmentation of BFR to team sports like futsal: Be cautious if you apply BFR in situations with near maximal effort such as jumping, acceleration and change of directions, as these types of movements are associated with peak muscle forces comparable to heavy lifting. And not least, the risk of adverse events in relation to contusions on blood flow restricted limbs, which is obviously not appealing.

The inclusion of BFR in futsal or similar sports is twofold. As shown in the current study the potential performance enhancement is obvious and for rehab and return to play this seems relevant. Regarding the high exercise intensity, olieveira et al. showed that Low-intensity BFR-interval running had similar benefit compared to high-intensity BFR.

In this post we present the outstanding results from a BFR-running RCT conducted on physically active women.

The study combined interval running with BFR and showed that training intensity and pressure are important for aerobic, anaerobic, and muscular performance!

Purpose: Comparison of different BFR stimuli and exercise intensities on aerobic, anaerobic, and muscle strength in 4 different groups, as a dose response study.

A 4-week intervention period consisted of 3d/week, 10 sets for each session as 2 min running on a treadmill with BFR interspersed by 1 min of recovery without BFR. The pressure was estimated from thigh circumference.

The four groups:
(IP-CE): Increasing Pressure with Constant Exercise intensity. (CPP-IE): Constant Partial Pressure with increasing Exercise intensity. (IP-IE) Increasing pressure with increasing exercise intensity. (CCP-IE): Constant Complete occlusion with increasing exercise intensity.

The study demonstrated improvements in all aerobic and anaerobic variables in all 4 groups, with a trend for greater gains for all parameters in response to progressing intensity and high BFR stimuli.

The CCP-IE (complete occlusion) group had a trend for the greatest overall effect (Vo2max Ꙟ 14.8%). – Though, it might be contrary for safety and could hypnotically lead to adverse events. Nevertheless, this is not the first study that shows a higher BFR stimuli is superior and this was also conducted on a young population + a trend for higher Ratings of Perceived Exertion (RPE) in the CCP-IE group.

Conclusion of the study: Interval based BFR-running with higher BFR stimuli and progressive intensity is superior for overall effectiveness.

We do not recommend complete occlusion for the general public, but it is common practice that you either progress effective running time or pace.

Another discovery is that circumference seems to be a legit way to set the pressure, while using Fit Cuffs, we recommend that you use the “App”.

This post is about a pragmatic research project at Odder Fitness Center.

A group of Physical Therapy Students from Copenhagen University of Applied Sciences are currently exploring the potential benefit of Low Load – Blood Flow Restriction Training (BFR) for people suffering from varying degrees of knee osteoarthritis (OA). (1,2)

Freely translated as:
The effect of BFR for pain, quality of life (QOL) and functioning in knee OA – a case series

Background for their study:
OA is the most common joint disease in Denmark (5%), most of those people have symptoms that negatively impact QOL. Currently, the treatment for these patients is exercise based, particularly popular is the initiative “Good Life with osteoArthritis in Denmark (GLA:D®)”

Purpose of the study:
To explore the importance of BFR for patients with knee OA in terms of pain level, functioning and QOL in clinical practice.

Study design:
A series of patients undergo PT supervised BFR twice weekly for one month.

As this is only a pragmatic trial designed to assess the outcome of BFR for knee OA in a clinical real-life practice, the sample size is too small for the results to be generalized and applied directly. But this is interesting from other perspectives, as it evaluates the potential effectiveness of BFR for this population in a direct setting. The next step for researchers would be a larger feasibility study on BFR for OA in direct clinical practice, which involves more factors to also measure cost-effectiveness.

If you have any questions related to this pragmatic study or how to utilize BFR for all types of arthritis (3), please comment below. Stay tuned for the upcoming results from this project.

Please mind that the video footage is not from this trial.

This is second post in a miniseries about the less known effects of BFR training.

Conventional high intensity exercise as both aerobic and resistance training have proven to reduce pain, known as exercise-induced hypoalgesia.

In the recent years, BFR research has also shown to reduce pain both acutely and long lasting, with huge implications for both accelerated rehab and performance. For the modulation of acute pain, at least 3 interacting pathways have been proposed (1):

(A) Changing the feedback of the central nervous system via the working muscle and hypoxia which produces pain inhibiting hormones. (B) The short increases of blood pressure simply leads to hypoalgesia. (C) The training induced discomfort creates a reduction in perception of other painful stimuli.

Regarding the potential chronic pain relief from BFR, research shows that in people with pain underneath the kneecap (PFP) and osteoarthritis this effect long lasting effect seems legit. As BFR has been compared to conventional resistance training to treat PFP and osteoarthritis in at least two separate RCT’s. It seems that BFR is superior in regards to both pain relief and improvement of strength of whom with symptoms reproduces during conventional resistance exercise (2,3).

A potential explanation of the augmented hypoalgesic effect of BFR vs conventional resistance exercise, is probably an interaction of acute pain modulation and less stress on the joints during exercise.

We recommend that future BFR research explores the potential comparable benefit for shoulder and elbow pain. But if you already know of any relevant research for the upper body, please let us know in a comment.

This post is a case story on how BFR can make a huge difference for post-surgery knee-rehab.
@SorenRotne 51, has always been active as a committed runner, swimmer and cyclist, but for years he had suffered from severe pain in his left knee because of damage to his meniscus and cartilage, as early signs of osteoarthritis.

After several doctor visits and numerous attempts with different terapedic modalities, such as acupuncture, massage etc., he was eventually referred for surgery. Subsequently he got the judgment from the surgeon: I advise you not attempt to run again.

Søren inaugurated her wife Runa, in this sad message. She immediately contacted her personal trainer at Odder Fitness Center, @AlexOdfit and asked if he could help Søren.

Alex was of a completely different view of the prognosis of Søren knee and the potential for a succesfull return to run. So Alex went to see Søren the day after the operation, explaining about BFR training with the use of a Leg Cuff for an immediate start of rehab.

Søren started by unweighted BFR exercises for the first 10 days, before he was joined by Lars Pårup (PT & MSc) who progressed the BFR training for an intense rehab at Odder Fitness Center. The progressive rehab continued for the next 10 weeks, after which Søren moved on to conventional resistance training.

Just 3 months after the operation, he performed a 1/4 ironman in just under 3 hours.

Søren states:
“A great commitment and a big thanks you to Lars and Alex at Odder Fitness Center, for a targeted and effective rehabilitation that was tough, but well worth it. Today, I can run and exercise 4-5 times a week without any pain.”

If this case has any interest or if you would like to know the exact protocol used in Sørens rehab, just ask!

This is the first post in a miniseries about the less known effects of BFR training.
It has been proven that complete occlusion over long periods, e.g. hours can be detrimental. Some even fear that blood clots or even venous thromboembolism (VTE) could be formed during BFR, which is known as a hypercoagulable effect. But please remember that BFR is a brief stimuly with a sub-occlusion pressure, that can be calculated by Web App or Android App (40-80 % LOP). The actual effect of BFR on the vascular system are probably the opposite i.e. hypocoagulational!

It has been proven that both BFR and regular resistance training results in optimized working conditions for the enzymes that degrade microscopic blood clots i.e. a fibrinolytic effect. It seems plausible that BFR promotes fibrinolysis and that blood thickening will be dissolved in connection with BFR as a long-term effect.(1)

Thus, for some patients there is additional considerations prior initiating BFR, as relevant contraindications should be screened for in the acute postsurgi­cal patient by a general VTE risk question­naire.(2) There is also need for additional research to completely understand the risks of BFR on the acutely post orthopaedic surgery patients, as the potential benefit for this population is enormous!

Conclusion: For the general population, BFR is likely beneficial in terms of the effects on vascular health , similarly to conventional resistance training. When the amount of research in BFR on vascular health increases, BFR might become a standard therapedic modality for various circulatory disorders and acutely after orthopaedic surgery.(3)

Exercise bands are the perfect supplementation to BFR-walking, as presented in this video with the collab of @Kipeconcept (KE:PE) and @Fitcuffs.

So far all of the walking-BFR studies have yet to explore the potential of elastic band resistance. Thus, at this point of time several studies have demonstrated impressive results of BFR-Walking!

It might not seem of much and for this particular athlete i.e. @frederiksass, this is probably not a sufficient stimuly. But we find the potential synergistic benefit of combining walking-BFR with elastic bands to be obvious, especially for the load compromised individuals. As the compression of relevant joints is kept to a minimum, the injured and the elderly can improve on numerous parameters of performance:

Park et al. explored the potential benefit of only 2-weeks BFR-Walking in an semi-athletic population, they found significant increases in VO2max, thigh muscles and improvements in 1.5-mile runs!

Regarding the elderly, Letieri et al. found that BFR-Walking improves functional tests, as the 30 s sit to stand, 6‐minute walk, timed up‐and‐go, and stept-test, by 10-20 min walking at 4 km/t for 5d/week. Also, Ozaki et al 2011 found improved arterial compliance after 10 weeks of BFR-walking in a similar population.

In another study on younger individuals, Sakamaki et al. found hypertrophy of the thigh (3.8%) and lower leg (3.2%) after only 3 weeks of BFR-walk as 6 d/week, 2 times/day. Thus, hypertrophy only occurred in muscles downstream relative to the cuff, as the non-restricted muscles did not.

We propose that proximal gains can be achieved by adding elastic bands to BFR-walks, as they predominantly increase the demand of the hip flexors, extensors and abductors.

This is the 4. post in a mini-series about BFR training as a supplement or substitute to traditional resistance training.

In the video you see #JustLiftArmBlaster and #FitCuffs in synergi to isolate the Biceps Muscles- the unmistakable hallmark of gym training for bodybuilders of all levels.

The Arm Blaster is a harness with a metal plate, that locks the arms into the grooved padded sections on each side. It provides greater isolation of the biceps, which means greater tension and stress on the muscles, equals more potential growth of the biceps. Besides, it is easier to keep a neutral spine giving the lower back less of a workout. The Arm Blaster works perfect with a conventional curl bar as it works both heads of the biceps.

Just grab the barbell with an underhand grip and let it hang with arms fully extended and palms facing forward. Press your upper arm back into to the Arm Blaster, bend your elbows and curl the barbell as close to your shoulders as you can, then lower the barbell back to the starting position.

With the supplementation of BFR you put a ton of work through the bicep muscle, sculpting serious mass and shape. That is why this combination of gadgets is so potent to stress the biceps, as the external fixation by the Arm Blaster makes it easier to use a heavier weight than a standard BFR biceps curl. This symbiotic effect seems of substantial importance as discovered by Buckner et al. as they discovered that loads equal or less than 15% 1 RM should be avoided if clinical applicable even with BFR.

Exercise bands are the perfect supplementation to just about any BFR workout, as presented in this video with the collab of @Kipeconcept (KE:PE) and @Fitcuffs.

We find it obvious why this is such a great combo, as you can augment your rehab or performance training anywhere and anytime by both external and internal resistance by simple means of KI:PE Lite and Fit Cuffs – Performance Lower Body.

This is especially relevant for rehab scenarios and load compromised individuals, as both modalities add resistance to the exercise without compression of the spine and comparatively adds minimal load on other relevant joints.

Walking lunges are effective as they engage nearly the entire lower body musculature and the stabilizers of the core and hip, in order to maintain balance. With the addition of elastic resistance you particularly increase the demand of the abductors and hip flexors. All of this is extremely beneficial for challenging the movement and increasing the effect of your workout

Begin your lunges so that your back knee almost touches the ground with a vertical thigh, then push yourself back up to starting position while keeping the back straight throughout. Perform the reps controlled to target both the quads, glutes, hamstrings and calves. Aim for a controlled pace with about 30 steps for each set x 4, with 30-45 s. interest rest.

About KI:PE Lite: Designed to ensure the maximum power of each workout by 3D attachment clips that ensures all-direction resistance, with the possibility to switch bands for optimal resistance.

This is the third post in a mini-series about BFR training as a supplement or substitute to traditional resistance training.

Below we will present a simple field-method to calculate the load needed for effective BFR stimulus.

In most BFR literature you will find that heavy lifting is to be avoided, especially as a novice to BFR. That is also why we recommend a load approx. 25% of the maximum load that can be lifted once, also known as 25% 1 RM.

But most people do not know their actual 100% 1 RM, and in a rehab setting, this is often not applicable to test by direct methods. That is also why we recommend to use a more simple, thus indirect method.

For general exercises you might recognize the load that you are able to lift for a maximum of 10 reps. This load should be multiplied by 1.3 or 1.4 if you are slightly more optimistic regarding your 1 RM.

Example: Estimated maximum load in a traditional leg press for a single set of 10 reps (10 RM) = 140 kg.

140 kg x 1.3 = 182 kg multiply this by 0.25 ≈ 45 kg. Which is actually pretty close to 1/3 of the estimated 10 RM, to use as a rule of thumb.

But please remember for the estimation of 1 RM, this field method should be modified for bodyweight exercises i.e. squats, by including the weight of the person. Besides, this is primarily recommended to be used with the generic 30x15x15x15 rep protocol.

Occlusion training (BFR) is not just for people with injuries, pain or aches as the potential for performance optimization is huge for all athletes of any level!

Especially the king of upper body compound exercise, the bench press, has been explored in at least 3 studies with the augmentation of BFR.

In a study by Zachary et al., the BFR group underwent the common 30x15x15x15 protocol, but with progressive loads from 20 to 32 % 1RM for 3/week in the 4 weeks training period. The BFR group demonstrated significantly greater increases in bench press performance (6 kg) compared to a conventional high load training group (1.5 kg).

Yasuda et al. (2010) looked at how non-restricted trunk muscles are affected by compound exercise with the supplementation of BFR. The BFR group trained twice daily, 6d/week for 2 weeks, performing bench press at 30% 1RM with the common 30x15x15x15 protocol. The results were significant, as an increase in 1RM bench press in the BFR group of 6% with no improvements in the non BFR group. Muscle thickness in the triceps and pectoralis major increased by 8% and 16% respectively in the BFR group, with just about no change in the non BFR group.

Yamanaka et al. (2012) studied BFR on National Collegiate Athletic IA football players, but with a lighter load of 20% 1RM, thus higher rep protocol as 30x20x20x20. The results concluded that the average 1RM bench press increased by 7.0% in the BFR group, which was significantly greater than the 3.2% increase in the non BFR group.

Conclusion: The data from the 3 studies suggests that BFR is effective for improving bench press strength and muscle size both upstream and downstream relative to the cuff. Probably most potent with loads above 20 % 1 RM, thus obviously, only when clinical feasible to use higher loads.

Occlusion training (BFR) is not just for people with injuries, pain or aches as the potential for performance optimization is huge for all athletes of any level!

Just take a look below, as we present the original training protocol and results from the famous study on elite rugby players. As this is particularly interesting for everyone interested in performance optimization.

The inclusion criteria for this study was a history of at least 5 consecutive years of conventional resistance training prior enrollment. .
The actual training protocol for the group of interest (BFR) was very simple: Only 4 sets of resisted knee extensions to voluntary failure, with an inter-set rest period of 30 s. Though, importantly augmented by BFR, but only done twice a week for 8 weeks as a supplement to their normal training regime.

However, the relative load where slightly heavier than commonly used in BFR studies, as the load intensity was 50 % of 1 RM. But nevertheless, the researchers found tremendous progress in regards to strength and cross-sectional area of knee extensors ≈ 14 % and 15 %, respectively, besides the functional markers of muscle endurance.

Individuals with many years of resistance training normally reach a plateau in their progress of either strength or hypertrophy. Particularly, such individuals can achieve great improvements by augmenting their training with Fit Cuffs, as this is an ideal supplement to virtually any workout routine.

Conclusion: Resistance exercise augmented by BFR causes, in almost fully developed athletes, relevant increases in muscle size, strength and endurance.

August 26, 2019

This is the second post in a mini-series about BFR training as a supplement or substitute to traditional resistance training.

Here we present the relevant parameters to consider for appropriate intensity in BFR.

The primary parameters are common: Relative load (% of 1 RM), reps and percentage of voluntary failure. Secondary parameters: Tempo (time under tension) and rest between sets. As slow tempo, isometric holds and shorter rest periods between sets equals relative higher intensity. Additionally, consider the overall volume (load x reps).

BFR should be interpreted as an additional parameter. For simplicity, this is like adding more resistance and as consequence the load must be less than normal. If you do higher relative pressures the internal load is higher and you should use less weight, to obtain the same relative intensity. This is why BFR is very potent directly after surgery, as high external load is contraindicated but higher pressures can be implemented safely in most cases.

As a rule of thumb, if you use the typical protocol of 30x15x15x15 reps with 30 s. inter-set rest, use a load about 25-35 % of 1 RM, with a pressure of 40-80 % LOP. If for any reason contraindicated to use a load of 20 % of 1 RM, use a higher relative pressure. For more advanced users, try higher loads but less pressure, longer inter-set rest period and fewer reps pr. set.

The combined intensity is sufficient when reaching voluntary failure within the 30x15x15x15 protocol. Then for the concecutive session, re-think either your load, pressure or inter-set rest period.

August 21, 2019

This is the first post in a mini-series about BFR training as a supplement or substitute to traditional resistance training.

In this post about exercise selection we argument for doing compound exercises that works multiple muscle groups, as this is preferable for most people in regards to overall effect. We recommend a load that is 20-50 % of 1 RM, which is trivial for most people doing BFR.

Squat or lunges is compound exercises that works the quadriceps, glutes, calves, etc. This can be paired with romanian deadlifts that primarily works the glutes and hamstrings.

The same principals are extrapolatable for upper body workouts. If you do chest press that works the pectoralis deltoideus, triceps, etc. then try to pair with a pulling motion which works primarily the opposite muscles

Of course, this is only a generic recommendation as individuals might have different preferences, injuries or minor pain and aches contraindicating multi joint exercises to be used. Another aspect to consider is the overall training volume, which is relevant for people undergoing high volume training. In these cases, single joint exercises might be a better option.

The 30/15/15/15 protocol with 30 s. interset rest period is what appears the most in the literature which also seems convenient from a clinical perspective.

If the total of 75 reps can be completed ad load for the next workout. If less than 60 reps were completed, we recommend to lower the load, or just prolong the rest period with 10-15 seconds.
