背景：建筑工人的职业体力活动（OPA）和休闲时间体力活动（LTPA）缺乏量化。目标：描述建筑工人的体力活动能量消耗（PAEE）、体力工作量以及PA干预的效果。方法：67名建筑工人自我报告他们的体力活动（PA），直接进行PA评估（PAEE），并使用“姿势、活动、工具和处理”工具观察OPA。 PA 干预（干预；n = 29，对照；n = 24）包括每周 3x20 分钟训练，持续 12 周。结果：基线中位 OPA 为 5036 MET 分钟/周，LTPA 为 2842 MET 分钟/周，p < 0.01。直接记录的 OPA 为（平均值 +/- SE）：56.6 +/- 3.2 J/kg/min，LTPA 为：35.7 +/- 2.2 J/kg/min (p < 0.001)。超过 50% 的参与者在>= 25% 的工作时间中进行了手动物料搬运。干预后，与对照组相比，培训组总体 PAEE 降低，但在工作期间并未具体降低。结论：OPA 在共识指南中提出的最大推荐水平 1/3 内，但并未随着 PA 干预而降低。
Background: There is a lack of quantification of occupational physical activity (OPA) and leisure time physical activity (LTPA) among construction workers.Objectives: To describe physical activity energy expenditure (PAEE), physical workload, and the effect of a PA-intervention among construction workers.Methods: Sixty-seven Construction workers self-reported their physical activity (PA), had PA assessed directly (PAEE), and observed OPA using the tool "Posture, Activity, Tools and Handling." The PA-intervention (Intervention; n = 29, Controls; n = 24) included 3x20-min training/week for 12 weeks.Results: Baseline median OPA was 5036 MET-min/week and LTPA 2842 MET-min/week, p < 0.01. OPA directly recorded was (mean +/- SE): 56.6 +/- 3.2 J/kg/min and LTPA was: 35.7 +/- 2.2 J/kg/min (p < 0.001). Manual material handling was performed for >= 25% of working time by more than 50% of the participants. Post-intervention, the training group reduced overall PAEE compared to the control group but not specifically during work.Conclusions: OPA was within the maximum recommended level of 1/3 proposed in consensus guidelines but did not decrease with PA-intervention.
