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 as 6 BFR-players vs. 6 No-BFR. 10 sessions as small sided games 3 vs. 3, 3 min play followed by 2 min rest as 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 muscle peak 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. But regarding the high exercise intensity, olieveira et al. showed that Low-intensity BFR-interval running had similar benefit compared to high-intensity BFR. . Source: Amani et al.

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". . 1st. pic- copyright @elitestlab. .

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) in a real setting. (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. .

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. . Thanks to @Sinisa_Entrenador for the videos. .

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 adwise 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 unweigted 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 with out any pain." . If this case has any interest or if you would like to know the exact protocol used in Sørens rehab, please make a comment below.

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 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 with Fit Cuffs is a brief stimuly with a sub occlusion pressure you can identify by the The 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. . (SOURCE) Park et al.

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. They find 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. . SOURCE: Reynolds et al. (2006) Prediction of one repetition maximum strength from multiple repetition maximum testing and anthropometry.

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. . SOURCE: Zachary et al.

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. .

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. .

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. .

As explained in a previous post BFR can successfully be used to augment the effect of cardiovascular exercise. These effects are presented in a review by H. Bennett and F. Slattery as they discover that BFR can improve aerobic capacity (VO2 max). . Increased muscle capillarization and central adaptations after a training period results in improvements in VO2 max! But also on running endurance performance even at low intensities and low volumes of BFR training! . This is beneficial for individuals in prehab or rehab or just for everyone undertaking concurrent high intensity strength or endurance training, as the effects are archived with much less mechanical stress on the body. . Please check below for two easy to follow protocols to try on yourself to improve VO2 max with Fit Cuffs®: . Pressure calculated by the Fit Cuffs App “fitcuffs.dk/web-app” or about 50-80 % of resting state LOP. . 4 to 6 consecutive weeks. Complete 6 training sessions each week. A maximum of 2 training sessions each day equals 3 days of exercise with at least 5 min complete rest between sessions. . Interval or intermittent based protocol: 5 intervals at an intensity about 50 % VO2 max then progressed by 1 interval and 5 % intensity for each week. The intervals consisting of 2 minutes of effort followed by 1 min passive rest. Cuffs deflated during the rest period. . Continuous protocol: 8 min with constant pressure and constant intensity at about 40 %. Progressed by 2 min and 5 % intensity each week. .

This is the second post in a miniseries about BFR cuffs used for pneumatic devices such as Fit Cuffs® and the impact of different parameters which are relevant for in vivo applications. . As explained in the recent post the most important factors are the width and the elastic properties or pliability of the cuff. . Different materials are used for BFR cuffs as some are made of elastic textiles whereas other cuffs are made of less pliability materials i.e. nylon. . The research shows that the acute muscular responses are similar and that elastic vs. less-elastic cuffs set at the same pressure restrict blood flow similarly at rest. During exercise the research data finds no differences in markers of blood flow or Ratings of Perceived Effort (RPE), even considering the different elastic properties suggesting that cuffs of different elasticity but same width causes similar BFR stimulus. . Though, the research data shows preliminary evidence for pliability not being an important factor. The nature of the cuff material will influence the fluctuation of pressure that occurs during muscle contraction e.g. expansion underneath the cuff which is relevant for comfort and mechanical tension. . Conclusion: Both the width and to a less degrees the pliability of the cuff has meaning full implications for BFR Training. . Fit Cuffs® is designed with a Upper Body Cuff that is more pliable then the Lower Body Cuff because the expansion of the upper arm muscles are greater than of the thigh muscles. But be aware when applying BFR with Fit Cuffs® that you must completely deflate the cuffs before attachment as this will impact blood flow at the same pressure and not at least the fit during training. .

This is the first post in a miniseries about BFR cuffs used for pneumatic devices such as Fit Cuffs® and the impact of different parameters which are relevant for in vivo applications. . The two most important factors to consider are the width and the elastic properties or pliability of the cuff. . As for the width of the cuff the research data has proven this as the second most important factor for the pressure needed to elicit arterial occlusion pressure (AOP), just after limb circumference. . The data from several studies validates that the width has an inverse correlation for the pressure needed to elicit AOP during passive BFR protocols such as pre-ischemic conditioning. .  It has been speculated, that less pressure and thereby less mechanical tension associated with wider cuffs is less harmful for the tissue underneath the cuff. However, the research data actually propose that the ischemic crisis e.g. shortage of oxygen + time and not the mechanical tension, to be the important risk factors for tissue damage and prolonged inhibited nerve conductivity. . However, in BFR training wider cuffs (not considering elasticity), are associated with less fluctuation of pressures when muscles expands, which is relevant for the brief discomfort when muscles contracts. Though, this is a trade-off, as wider cuffs can be detrimental for range of motion and perceived effort. . Fit Cuffs® is actually designed to be a compromise considering those factors to accomplish One-Size-Fit-All! . But be aware when applying Fit Cuffs that you must completely deflate the cuffs before attachment, as this will impact the distribution of pressure into the tissue and not at least the actual fit. .

This is a #repost from @elitetestlab as they are testing the benefits of Blood Flow Restriction (BFR) with #fitcuffs on the track. . On the second picture, you can see the athlete doing 6 intervals of 2 min at 12 km/h (7.5 mph) with a pressure of 120-220 mmHg – which is actually very intense but described as tolerable. . He is also testing them in the lab, where oxygen uptake and blood lactate are measured to see how energy turnover changes at different cuff pressures. It can be used to find out how occlusion training (BFR) can enhance endurance in running and cycling which can be extrapolated to other sports with high petition on endurance. . You can read more about the vast applications of BFR to improve sports performance on fitcuffs.dk/com and elitetestlab.dk. . Please see the relevant research on endurance training augmented by BFR on the muscular adaptations (muscle glucose uptake, ion regulation, improved fatigue time, and greater blood flow). . Actually, the portraited athlete is the first author of the two uppermost research articles. . /Pictures are subject to copyright of @elitestlab. . SOURCE: Christiansen et al. (2018).

This is the 3rd post in a mini-series on the different ways to utilize Blood Flow Restriction (BFR). This is still relevant as false dichotomies in BFR still thrives, i.e. safe vs. unsafe or effectful vs ineffectfual. . When measuring Limp Occlusion Pressure (LOP) with a cuff like Fit Cuffs in the Lower body, of 100 randomly picked people 90 % will be in the range of 150-250 mmhg. Then just add limb circumference, which alone explains about 70 % of the variance in LOP (1), we get into the sweet spot of 40-80 % LOP using a simple algorithm. As our app includes other factors such as accustomization and gender the utility is just about complete: www.fitcuffs.dk/web-app or Google Store "Fit Cuffs". . Pros: Effective, Convenient and Safe as the pressure is 40-80 % resting LOP measured by doppler or standard blood pressure monitor. . Cons: For Ischemic Pre Conditioning you need a small margin to sustain 100 % LOP. . Conclusion: Algorithm based methods are simple, fast and effective. This is probably the most feasible and convenient way to personalize pressures and utilizes Fit Cuffs® pneumatic system about perfect. . Disclaimer: The algorithm/app is developed exclusively to be used with Fit Cuffs Training system. .

This is the 2. post in a mini-series on the different ways to BFR in clinical practice or supplement for the general public. . As explained in the last post beware of the incentives when people preach about how to do BFR. Some go as far as claiming that if clinicians use it in the wrong way and experience adverse events BFR could possibly be banned. . Though, this post is about practical BFR (pBFR) – The to go method when using elastic bands: . The literature suggests a subjective scale from 0-10 with a prefered perceived tightness anywhere from 4-8 (1). Some preliminary studies have explored the validity of measuring the band length as a way to standardize the pressure, but this is probably to early to be operationalized (2). . But is this method is actually safe? Yes, even considering the arbitrary and subjective nature, as even with a tightness of 100 % restriction, blood flow is not completely occluded when muscles contract (3,4). But pBFR is hard to standardize and thereby not optimal for muscle strength and hypertrophy especially relevant in clinical settings (5). . Pros: Convenient in every sense and cheap. Cons: You should take every set close to voluntarily failure and difficult to standardize. . pBFR do not utilize Fit Cuffs® precise pre- and post-exercise pressure readings and a submaximal method from our perspective. . SOURCE: (1) Lowery et al. 2018 - Practical blood flow restriction training increases muscle hypertrophy. . (2) Abe et al. 2019 - A method to standardize the blood flow restriction. .

This is this first post in an upcoming miniseries on the different ways to standardize/personalize the pressure in "BFRE" with reference to clinical experience, research articles and it is potential utility with Fit Cuffs®. . Recently, different methods have been proposed and debated, especially the use of Limp Occlusion Pressure (LOP) has been proposed as the “only” way to do it right. Some individuals even go as far as claiming that autoregulated systems e.g. hospital standard equipment is the only safe way to do BFR, when in reality many different methods, if used appropriately is completely safe. Thus, obviously different methods come with pros and cons. . So when people claim that some methods and equipments are unsafe and in effective, beware of the potential incentives that lies behind these false dichotomies. . So follow us and look out for the upcoming post on practical BFR (pBFR)! . In the mean time go check the available Web App on Fitcuffs.dk. And for all of you who already purchased a Fit Cuffs product, please DM us for instant access to the android app! Ps. Algorithm based pressures will also be discussed in an upcoming post.

This post is actually a follow-up on the fixation of a torn supraspinatus. Alex got operated in his shoulder after a crash on MB. He was told by the surgeon that he should expect 13 months of rehab before assessment of the potential success of the operation, as the supraspinatus was completely torn off the upper arm. . But after only 5 months of intensive rehab with focus on occlusion training (BFR) combined with VR e.g. #FitCuffs and #GonioVR in #OdderFitnessCenter, he was declared 100 % rehabilitated. This was evaluated by assessment of ROM and strength by the physical therapists at the rehabilitation center – municipality of Aarhus. . An explanation of why BFR seems beneficial in this case and similar cases are thought to be multifactorial: . A. BFR slows down the loss of muscle mass, with regard to the muscles lying below, but also upstream relative to the cuff (1). This is very interesting as a tear and surgical intervention are normally treated with immobilization of the limb. . B. A potential secondary explanation is that bone healing seems accelerated after intensive use of BFR, thus in these studies downstream relative to the cuff. (2,3,4). . C. Potential specific tendon healing properties of BFR. (5,6) .

A relative new systematic review on the effects of BFRT on aerobic capacity and performance have been published by H. Bennett and F. Slattery. . The authors find that despite some methodological problems, BFRT seems to be a potent supplement to cardio-vascular exercise. As the combination of BFR with aerobic exercise can improve VO2 max irrespective of training intensity! That is also why the authors, propose that the key benefit of BFRT is when individuals can not tolerate high-intensity aerobic exercise. . An interesting sub finding is that it seems to stimulates different systems in older and younger individuals, peripheral (muscular fitness) and central (aerobic fitness), respectively. . The authors conclude that BFR-aerobic exercise at light intensities cause improvements in both aerobic fitness and aerobic performance in young adults when using higher occlusion pressures (130 mmHg or greater). This statement can be debated as it is already proven that the width of the cuff relative to the circumference of the limb under restriction are the largest determents of the restriction of blood flow (LOP). . Readers should also consider the type of occlusion gear they use in their practice. As the majority of the original studies utilizes dynamic pressure systems, it is not directly applicable to use the same pressure (130 mmHg) on a static system like Fit Cuffs® or similar products. . That is why it is important always to approximate the pressure individually with respects to limb size, cuff width, age and probably also training intensity. When using Fit Cuffs® we recommend using the App which is available at www.fitcuffs.com and google store. SOURCE: H. Bennett and F. Slattery (2019) Effects of Blood Flow Restriction Training on Aerobic Capacity and Performance: A Systematic Review.

In the recent posts we have seen how cardio vascular exercise effectively can be augmented by BFR. This clip follows this trend as the good old stair climbing machine (SCM) is in the spotlight. . As presented in the cycling post it is possible to improve VO2 max with BFR at an intensity below the normal threshold, i.e. < 50 % of VO2 max (without BFR). That is also why SCM can be beneficial at much lower watts as we utilize BFR. . Well-trained individuals would normally have to climb at a high pace on a SCM to get the cardio vascular and peripheral benefit. . Thus the impact of the SCM can help strengthen and maintain bone health, as for all weight bearing exercises, in early joint rehab or in more chronic cases, the relative high impact of SCM can be disruptive. . In a normal gait or running pattern the impact occurs when the knees and hips are at an angle about 0-20 degrees of flexion, where the cartilage is thickest. But when we take a step “upstairs” the knee and hips are in an angle about 40-70 degrees of flexion, where the cartilage is much thinner. This is not a problem for a healthy joint, but for all you that have been working in a musculoskeletal rehab setting you know that stair climbing often aggravate symptoms. . This is why BFR becomes interesting, as we are able to slow down the pace considerably, equal lesser impact force, without compromising the primary benefits of the SCM e.g VO2 max! . As a metabolic side effect, if your exercise is really strenuous your Post Oxygen Consumption (EPOC) is increased for several hours afterwards. . #fitcuffs #inocera #occlusiontraining #bloodflowrestriction #evidencebased #okklusionstræning #kaatsu #bfrtraining #oclusao #okklusjonstrening #oclusaovascular #ocklusionsträning #stairmaster #vo2max #kneepain #hypertrophy #exercise #workout #personaltraining #personligtræning #bfrbands #bfr #trainsmart #strongbyscience #bfrtraining #bfrexercise #bodyweight #stairclimber #afterburn #arthritis #acl

Research proves that the trap/hex bar may help you deadlift (DL) with more power (1). . The main reason of this change in power output is that the mass moves closer to the center of gravity, with lesser torque around the lower back. . This has relevant change in the muscle activation pattern as the hamstring and back muscles i.e. erector spinae works less than the conventional DL and shifts the load to the quads and calves. . It seem that the athlete is able to generate more peak force and peak power. Besides one could argue that it is better for optimizing sports performance as the movement is closer to the muscle activation pattern in acceleration and jumping sports. . Thanks to @bevaegelse for sharing this clip of low-load hex bar DL augmented by effective implementation of BFR with Fit Cuffs in his rehab after knee surgery. .
