Why & When?

Occlusion training for bodybuilders only?

No, not at all! In fact, there are important research on miscellaneous muscle and skeletal pathologies which proves that occlusion training has significant effect on both strength and Patient Reported Outcome Measures (PROM)!

As a rule of thumb occlusion training is indicated if you have an acute or overload injury where you cannot do conventional resistance training i.e. lift heavy. For example, following orthopedic surgeries with relevant weight-bearing restrictions. Or more chronic conditions such as arthritis, as a majority will find joint pain worsens during heavy training. In theses cases occlusion training should be “first-line therapy”.

One can wonder why few private or public providers offers BFR? – But as with so much other new technology, thus evidence-based by research, the implementation is always delayed. Especially considered the amount of high quality research i.e. randomized controlled trials and the meta-analysis, occlusion training is here to stay and grow in popularity.

Below is listed some of the relevant issues and pathologies in which scientific litterature suggests that occlusion training is an effective treatment strategy.

The 4 Pillars of BFR

BFRE can be effectively combined with training, in several different ways and even without training! These different “applications” should be used accordingly to the objective of the training, this is called “implications”. In popular science we identify these applications as “the 4 pillars of Blood Flow Restriction”:

 

1. Application

Passive BFR: Short intervals with partial or complete occlusion with or even without muscle work. Follow this link for an abstract on how to slow down loss of muscle mass in even in the absence of muscle work.
Implications: For example, as partially bedridden after major orthopedic surgical operations with severe restrictions, e.g. reconstruction of cruciate ligament or traumatic shoulder luxation’s.
Relevant products for you or your client will be “Rehab – Lower Body” or “Rehab – Upper Body”.

2. Application

Combined with cardiovascular exercise: Performed continuously or in intervals with your preferred exercise.
Implications: In extension of 1st application when weight bearing is aloud, simple walking on a treadmill or bike in combination of BFR are useful. You can actually improve your muscle mass, strength and aerobic function depending on the starting point even at this stage. In daily speech, this means that one can improve rapidly, i.e. “fast-track rehabilitation”.
Relevant products for you or your client, primarily: “Performance – Lower Body”, but also “performance – Upper Body” e.g. in the case of exercises with relevant fatigue of the upper body muscles.

 

3. Application

Combined with low- or moderate load resistance training: Many know BFRE primarily as supplement to low load training.
Implications: For all who wants to increase or maintain their strength but especially for those who want to build or maintain muscle mass often as supplementation to lifting heavy loads.
Relevant products for you or your client: “Fit Cuffs – Complete”.

4. Application

Ischemic pre-conditioning and restitution modality (before or after sports performance): Recent research shows that short-term intermittent occlusion can be used to augment sports performance. Post sports you can optimize recovery time.
Implications: Primarily within elite sports.
Relevant products for you or your client: “Performance – Lower Body” or even “Performance – Upper Body” especially used in the professional climbing/bouldering community.
