Effects of blood flow restriction (BFR) with resistance exercise on musculoskeletal health in older adults: a narrative review

AbstractBackgroundAging leads to a number of structural and physiological deficits such as loss of muscle mass and strength. Strength training at ~  70% of 1 repetition max (RM) is recommended to prevent age-related loss of muscle mass and strength. However, most older adults may not be able to perform 70% of 1RM or higher intensity. An alternative exercise training program combining low intensity resistance exercise with blood flow restrict ion (BFR) can result in similar acute and chronic benefits to skeletal muscles in older adults.Main body and short conclusionThe potential mechanisms involved are discussed, and include reactive hyperaemia, metabolic stress, and hypoxia. Key issues and safety with the use of BFR in older adults, especially those with chronic conditions are also discussed. Although there has been no reported evidence to suggest that BFR elevates the risk of clinical complications any more than high intensity exercise, it is recommended for individuals to be medically cleared of any cardiovascular risks, prior to engaging in BFR exercise.
