Beginning early in midlife, natural/primary aging is inevitably associated with a progressive reduction in muscle mass and function. This process can progress with aging to a substantial loss of strength, particularly in the lower extremities, reducing mobility. This condition, commonly referred to as sarcopenia, can result in frailty, reducing one's ability to live independently. This article reviews the underlying biological process contributing to the development of sarcopenia and the roles of regular exercise and nutritional support for attenuating aging-associated muscle loss as well as risk and management of sarcopenia and associated frailty.
从中年早期开始,自然/原发性衰老不可避免地伴随着肌肉质量和功能的逐渐下降。随着年龄的增长,这个过程会导致力量大幅丧失,尤其是下肢力量,从而降低活动能力。这种情况通常被称为肌肉减少症,会导致身体虚弱,降低独立生活的能力。本文综述了导致肌肉减少症发生的潜在生物学过程,以及规律运动和营养支持在减轻与衰老相关的肌肉流失方面的作用,以及肌肉减少症和相关虚弱的风险与管理。
