Abstract：
BACKGROUND: Aging 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 restriction (BFR) can result in similar acute and chronic benefits to skeletal muscles in older adults.
UNASSIGNED: The 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.

摘要：
背景：衰老导致许多结构和生理缺陷，例如肌肉质量和力量的丧失。建议在1次重复最大（RM）的70％进行力量训练，以防止与年龄相关的肌肉质量和力量损失。然而,大多数老年人可能无法执行1RM或更高强度的70%。一种将低强度阻力运动与血流限制（BFR）相结合的替代运动训练计划，可以对老年人的骨骼肌产生类似的急性和慢性益处。
■讨论了所涉及的潜在机制，包括反应性充血,代谢应激，和缺氧。在老年人中使用BFR的关键问题和安全性，特别是那些患有慢性病的人也进行了讨论。尽管没有报道的证据表明BFR比高强度运动更能提高临床并发症的风险，建议个人在医学上清除任何心血管风险，在进行BFR锻炼之前。
