背景：体力活动和肌肉力量之间的关系尚未在老年人中详细研究。本研究的目的是检查≥ 60岁的成年人体力活动与手握力之间的相关性。 方法：使用来自英国生物银行研究的数据，我们纳入了66582名具有完整基线数据的男性和女性，以及6599名具有4.5年随访数据的男性和女性。我们使用多元线性回归模型来检查中到剧烈体力活动（MVPA）和握力之间的横截面，纵向和双向关联，调整年龄，性别，身高，体重，健康状况，教育水平，吸烟状况，汤森剥夺指数和退休状况的潜在混杂。 结果：在横断面分析中，握力与MVPA呈线性正相关。纵向上，基线MVPA与随访时的握力无关{五分位数[Q] 5和Q1之间的差异= 0.40 [95%置信区间（CI）：-0.14，0.94]kg}，而基线握力与随访时的MVPA相关[Q5 vs Q1 = 7.15（1.18，13.12）min/d]。保持/增加MVPA时间的人在握力方面没有任何好处[0.08（-0.20，0.37）kg]，而增加握力的人每天在MVPA中额外花费3.69（0.20，7.17）分钟。 结论：促进力量训练活动可以使老年人能够并保持定期参加体育活动。
Background: The relationship between physical activity and muscular strength has not been examined in detail among older adults. The objective of this study was to examine the associations between physical activity and hand grip strength among adults aged ≥ 60 years. Methods: Using data from the UK Biobank study, we included 66 582 men and women with complete baseline data and 6599 with 4.5 years of follow-up data. We used multiple linear regression models to examine the cross-sectional, longitudinal and bidirectional associations between moderate-to-vigorous physical activity (MVPA) and grip strength, adjusting for potential confounding by age, sex, height, weight, health status, education level, smoking status, Townsend deprivation index and retirement status. Results: In cross-sectional analyses, grip strength and MVPA were linearly and positively associated with each other. Longitudinally, baseline MVPA was not associated with grip strength at follow-up {difference between quintile [Q] 5 and Q1 = 0.40 [95% confidence interval (CI): -0.14, 0.94]kg}, whereas baseline grip strength was associated with MVPA at follow-up [Q5 vs Q1 = 7.15 (1.18, 13.12) min/day]. People who maintained/increased time spent in MVPA did not experience any benefit in grip strength [0.08 (−0.20, 0.37) kg] whereas those who increased their grip strength spent 3.69 (0.20, 7.17) min/day extra in MVPA. Conclusion: Promotion of strength-training activities may enable and maintain participation in regular physical activity among older adults.
