背景和目的：观察到的衰老后果是肌肉性能下降，包括肌肉力量和肌肉力量的损失。这种下降可能导致功能和独立性的丧失，是老年人残疾的预测因素。虽然2008年美国人身体活动（PA）指南提供了肌肉强化的指导方针，但没有证据表明每周对所有主要肌肉群进行2次肌肉强化与已知是老年人虚弱发展或进展的重要因素的措施的更好表现有关。本研究的目的是评估老年人的肌肉强化和有氧PA行为，并确定PA行为和身体性能指标之间的关系。研究方法：这是一项对85名社区居住的非卧床成人（50名女性，35名男性）进行的横断面研究，平均（标准差）年龄为67.5（5.6）岁。所有人都使用了一项基于互联网的调查，TREST（跟踪阻力锻炼和力量训练），以报告肌肉增强和有氧PA行为。在完成调查后，获得了握力、10米步行试验（10-MWT）、五次坐立试验（FTSST）和爬楼梯试验（SCT）等身体性能指标。参与者根据他们是否符合2008年PA指南进行分组：（1）每周肌肉强化2天或更长时间，（2）每周使用所有主要肌肉群进行肌肉强化2天或更长时间，或（3）每周150分钟或更长时间的有氧中度至剧烈体力活动。使用多变量分析，对符合和不符合指南的参与者进行身体表现指标的比较。显著的多变量结果随后进行单尾t检验。结果和讨论：每周进行2天或2天以上肌肉强化的参与者在握力和SCT测量方面表现明显更好。只有27%的参与者符合每周使用所有主要肌肉群2天或更多天的更严格的加强指南，这些人在SCT和FTSST上表现得更好。符合有氧活动指南的受试者在SCT、FTSST和10-MWT上的表现明显更好。然而，同时符合加强运动和有氧活动指南的参与者在所有4项身体表现指标上的表现明显优于不符合这两项指南的参与者。结论：满足有氧和肌肉强化活动的指南可能是老年人保持肌肉力量，肌肉力量和步态速度的最有效方法，但这一结论必须通过干预研究进行验证。
Background and Purpose: An observed consequence of aging is a decline in muscle performance that includes a loss in both muscle strength and muscle power. This decline can lead to loss of function and independence and is a predictor of disability in older adults. Although the 2008 Physical Activity (PA) Guidelines for Americans provides a guideline for muscle strengthening, there is no evidence that performing muscle strengthening 2 times a week for all major muscle groups is related to better performance on measures known to be important factors in development or progression of frailty in older adults. The purposes of this study were to assess muscle-strengthening and aerobic PA behaviors in older adults and to determine the relationship between the PA behaviors and physical performance measures. Methods: This was a cross-sectional study of 85 community-dwelling, ambulatory adults (50 women, 35 men) with a mean (standard deviation) age of 67.5 (5.6) years. All used an internet-based survey, TREST (Tracking Resistance Exercise and Strength Training), to report muscle-strengthening and aerobic PA behavior. Physical performance measures of grip strength, 10-m walk test (10-MWT), five-time sit-to-stand test (FTSST), and stair climb test (SCT) were obtained following completion of the survey. Participants were grouped by whether they met 2008 PA Guidelines for (1) muscle strengthening 2 or more days per week, (2) muscle strengthening 2 or more days per week using all major muscle groups, or (3) 150 minutes or more per week of aerobic moderate to vigorous physical activity. Comparisons of physical performance measures were conducted between participants who met and did not meet guidelines using multivariate analyses. Significant multivariate results were followed with one-tailed t tests. Results and Discussion: The participants meeting muscle strengthening 2 or more days per week performed significantly better on measures of grip strength and SCT. Only 27% of participants met the more stringent-strengthening guideline of 2 or more days per week using all major muscle groups, and these individuals performed significantly better on the SCT and FTSST. The participants meeting the aerobic activity guideline performed significantly better on the SCT, the FTSST, and the 10-MWT. However, participants who met both the strengthening and aerobic activity guidelines performed significantly better on all 4 physical performance measures than participants who met neither of the guidelines. Conclusions: Meeting guidelines for both aerobic and muscle-strengthening activities may be the most effective way of preserving muscle strength, muscle power, and gait velocity in older adults, but this conclusion must be tested with an intervention study.
