Leisure-time physical activity (LTPA) is known to be associated with positive health benefits, but the role of occupational physical demands remains inconsistent. The purpose of the current study was to assess the relationship between LTPA and work ability in different occupational physical activity (OPA) levels between young adult men.
We performed physical activity measurements in work and leisure time with the long version of International Physical Activity Questionnaire (IPAQ) and work ability with the Work Ability Index (WAI) in 921 Finnish employed male volunteer participants. The participants were divided into LTPA tertiles I (< 8 MET-h/week), II (8-28 MET-h/week), and III (> 28 MET-h/week) and OPA tertiles I (0 MET-h/week), II (< 64 MET-h/week), and III (≥ 64 MET-h/week).
There was a significant relationship between LTPA and WAI in OPA tertiles (adjusted for age, alcohol consumption, working class status, BMI, and employment years). Moreover, each LTPA tertile showed significant linear associations with WAI (P < 0.001).
LTPA is positively associated with work ability among young adult men. More specifically, the relationships between LTPA and WAI were significantly greater in physically demanding jobs than in more passive jobs. Our results indicate the importance of LTPA, particularly with individuals under higher work-related physical strain.
休闲时间体力活动（LTPA）已知与健康益处呈正相关，但职业体力需求的作用仍不一致。本研究的目的是评估 LTPA 与不同职业体力活动（OPA）水平的年轻成年男性工作能力之间的关系。
我们使用国际体力活动问卷（IPAQ）的长版本在工作和休闲时间进行体力活动测量，并使用工作能力指数（WAI）评估工作能力，共有 921 名芬兰受雇男性志愿者参与者。参与者被分为 LTPA 三分位数 I（<8MET-h/周）、II（8-28MET-h/周）和 III（>28MET-h/周）和 OPA 三分位数 I（0MET-h/周）、II（<64MET-h/周）和 III（≥64MET-h/周）。
在 OPA 三分位数中，LTPA 与 WAI 之间存在显著关系（调整年龄、饮酒量、工作阶级地位、BMI 和就业年限）。此外，每个 LTPA 三分位数与 WAI 呈显著线性关联（P<0.001）。
LTPA 与年轻成年男性的工作能力呈正相关。更具体地说，LTPA 与 WAI 之间的关系在体力要求较高的工作中比在更被动的工作中更为显著。我们的结果表明 LTPA 的重要性，特别是对于那些承受更高工作相关体力压力的个体。
