老年人日常生活活动（ADL）的维持涉及几个因素。骨骼肌的质量和力量是维持老年人独立性和生活质量的重要因素。最近的几项横断面研究表明，肌肉力量与身体健康和残疾的关系[1，2]。肌肉质量损失（肌肉减少症）在老年人中很普遍[3]，代表着一种健康受损的状态，伴有运动障碍、福尔斯和骨折的风险增加、ADL能力受损、残疾和丧失独立性[4-6]。害怕跌倒在老年人中很常见。患病率从21%到85%不等，女性高于男性，并随年龄增长而增加[7]。害怕跌倒的风险因素包括身体虚弱[8]、健康状况不佳[9]、肥胖、认知障碍、抑郁、平衡能力差[10]和至少一次跌倒史[7]。阻力训练是通过增加力量和身体表现来改善老年人身体功能的有效干预措施[11]。然而，阻力训练是否对所有级别的老年人都有效仍然存在争议。例如，我们报告说，肌肉力量下降是一个可靠的预测福尔斯只在体弱的老年人[12]。
SIR—Several factors are involved in the maintenance of activities of daily living (ADL) in older adults. Skeletal muscle mass and strength are important factors for maintaining independence and quality of life in elderly. Several recent cross-sectional studies have shown the associations of muscle strength with physical fitness and disability [1, 2]. Loss of muscle mass (sarcopenia) is prevalent in older adults [3] and represents an impaired state of health with mobility disorders, increased risk of falls and fractures, impaired ability to perform ADL, disabilities and loss of independence [4–6].Fear of falling is common in older adults. The prevalence varies from 21 to 85%, is higher in women than in men, and increases with age [7]. The risk factors of fear of falling are shown to be physical frailty [8], perception of poor health [9], obesity, cognitive impairment, depression, poor balance [10] and history of at least one fall [7]. Resistance training is an effective intervention to improve the physical function in older adults by increasing strength and physical performance [11]. However, it is still controversial whether resistance training is effective for all levels of elderly people. For example, we reported that decreased muscle power is a reliable predictor of falls only in frail elderly [12].
