The most impressive application of BFR training is in rehabilitation after injury, surgery, disuse and muscle wasting conditions BFR training has repeatedly been shown to be an effective method for increasing muscle mass 6 , strength 7 , muscular endurance 8 and sporting performance 9 in both males and females 10 . Research has not demonstrated a superior training effect of BFR when compared to traditional, high-load resistance training, therefore the key benefit is that a comparable 11 training response can be achieved with considerably lower loads, which has the potential to minimise load- induced injuries and reduce recovery duration between training sessions. It is also useful when the trainee does not feel sufficiently motivated to perform a high-load strength training session (that is, they are mentally fatigued and just ‘not feeling up to it’). Rehabilitation The most impressive application of BFR training is in rehabilitation after injury, surgery, disuse and muscle wasting conditions, such as paralysis injuries, cancer cachexia and sarcopenia, and for astronauts 12 . Muscle wasting is an inevitable consequence post-surgery or during recovery after an injury where a limb 12 | NETWORK SUMMER 2017 or muscle requires rest or immobilisation in order to reduce pain. Research has demonstrated that BFR is a highly effective training method to preserve or even build muscle mass in these conditions 13 , which is especially important when high-load training protocols might not be indicated due to potential aggravation to the surgery site, compromised joints or weakened connective tissue. A similar argument can be made for the effective application of BFR in the ageing population, where high loading may not be appropriate. BFR training has been shown to promote similar gains in strength and muscle mass compared to high-load training in the elderly 14 . World BFR expert professor Jeremy Loennecke has proposed a four sequential phase rehabilitation protocol for those recovering from injury 15 : 1) BFR alone during periods of bed rest or immobilisation; 2) BFR during low-work rate walking; 3) BFR during low-load resistance exercise and; 4) low-load BFR training combined with normal high-load training. Progression through these different phases should follow a continuum, with gradually increasing exercise intensities within each stage, to limit risk of further injury resulting from a return to training too early 16 . Protocols The most common protocol is to inflate the cuff around the upper thighs or upper arms and perform 30 repetitions of a movement, rest for 30 seconds, perform 15 reps, rest a further 30 seconds and perform a final set of 10 to 15 reps. The cuff would stay on for the entire three-set duration and only be removed after the final set has been completed. The 30/15/15 and 30/20/10 repetition schemes are the most commonly used BFR training methods, using approximately 30% or less of the individual’s 1RM.
