Abstract
Objectives: To evaluate the effects of an 18-week workplace gymnastics (WG) program on selected components of health-related physical fitness in administrative workers.
Methods: This non-randomized study (n=66) compared low (LA, <35 sessions) and good adherence (GA, ≥35 sessions) groups across an 18-week program (15-min sessions, 3x/week), assessing handgrip strength (HGS), flexibility, and lower-limb endurance.
Results: The GA group showed greater reductions in body fat (-1.7% vs -1.0%) and gains in muscle mass (+1.0% vs +0.8%), although not significant, and significantly higher post-intervention flexibility (30.9 vs 22.2 cm; p=0.004) and lower-limb endurance (33.0 vs 26.1 reps; p=0.0002). No significant HGS changes occurred. Attendance correlated positively with post-intervention outcomes.
Conclusions: Participation in WG was associated with selected components of health-related physical fitness; higher attendance was associated with better outcomes, without implying causality or a dose-response relationship.
目的：评价为期18周的工作场所体操（WG）计划对行政工作人员健康相关体质部分的影响。方法：这项非随机研究（n=66）比较低（LA），结果：GA组体脂减少幅度更大（-1.7% vs -1.0%），肌肉质量增加（+1.0% vs +0.8%），尽管不显著，但干预后柔韧性（30.9 vs 22.2 cm, p=0.004）和下肢耐力（33.0 vs 26.1 reps, p=0.0002）显著提高。HGS未发生明显变化。出勤率与干预后结果呈正相关。结论：WG的参与与健康相关体质的选定成分相关；较高的出勤率与较好的结果相关，不暗示因果关系或剂量-反应关系。
