本研究的目的是检查即将退休的健康男性和女性的膝关节伸/屈肌力量和身体活动。使用等速测力仪测量了95例患者（平均年龄59.4岁）双侧膝关节伸肌和屈肌群的峰值扭矩。在角速度为1.05和3.14 rad时进行等速同心收缩。(1)。身体活动，包括家庭活动、休闲活动和体育活动进行了评估。结果表明，所展示的平均峰值扭矩比以前报道的研究使用相同的方法，不同的人群相似的年龄和体型。超过三分之一的参与者久坐不动，只有13%的人足够活跃以获得健康益处。这群自我选择的健康工作成年人的肌肉力量差，体力活动少，这令人惊讶，而且可能引起人们的关注。退休是身体活动减少的潜在分水岭，而已知的年龄相关的身体表现下降表明，其中一些参与者在退休阶段很早就有失去功能独立性的风险。我们建议对临近退休的个人采取有效的健康促进干预措施，鼓励他们多运动。
The purpose of this study was to examine knee extensor/ flexor muscle strength and physical activity in healthy males and females approaching retirement. Peak torques of the knee extensor and knee flexor muscle groups were measured bilaterally in 95 individuals ( mean age 59.4 years) using an isokinetic dynamometer. Isokinetic concentric contractions were performed at angular velocities of 1.05 and 3.14 rad . s(-1). Physical activity, including household, leisure, and sporting activities, was assessed. The results show that the average peak torques exhibited were lower than previously reported in studies using the same methodology with different populations of similar age and body size. Over one-third of the participants were sedentary, with just 13% being active enough to obtain health benefits. The poor muscle strength and low physical activity of this self selecting group of healthy working adults were surprising, and potentially a cause for concern. The combination of retirement being a potential watershed for a decrease in physical activity and the known age-related decline in physical performance indicates that some of these participants are at risk of losing their functional independence fairly early in the retirement stage. We recommend the introduction of effective health promotion interventions for individuals approaching retirement, encouraging them to become more physically active.
