To explore the physical activity level of community environmental volunteering (CEV) participants and the differences in physical functions and daily activity patterns between the older adults who engaged in intensive CEV (≥15 hours/week) and non-intensive CEV (<15 hours/week) groups.
Cross-sectional study.
Three recycling stations in Taiwan.
In total, 113 community-dwelling older adults who regularly participated in CEV. The response rate was 53%.
The ActiGraph wGT3x-BT accelerometer for the percentage of sedentary, light, and moderate to vigorous physical activity (MVPA) of CEV time and awaken time; the Jamar hand dynamometer for grip strength; and the MicroFET3 muscle testing dynamometer for knee extension strength.
Analysis of covariance with the baseline characteristics as covariates.
Overall, MVPA, light, and sedentary activities accounted for 53.73%, 41.10%, and 5.23% of CEV time, respectively. The intensive group (n = 61) displayed greater dominant handgrip strength ( = .004) and higher MVPA percentage in daily life ( = .044) than the non-intensive group (n = 52).
CEV provides sufficient opportunities for older adults to perform physical activity. Intensive CEV is related to greater handgrip strength but not lower limb strength. Further study is needed to establish the causal relationship between CEV and health variates.
探索社区环境志愿活动（CEV）参与者的身体活动水平，以及从事高强度 CEV（每周≥15 小时）和非高强度 CEV（每周<15 小时）的老年人之间身体功能和日常活动模式的差异。
横断面研究。
台湾的三个回收站。
共有 113 名经常参与 CEV 的社区居住老年人。回复率为 53%。
ActiGraph wGT3x-BT 加速度计用于测量 CEV 时间和清醒时间的久坐、轻度和中高强度身体活动（MVPA）百分比；Jamar 握力计用于握力；MicroFET3 肌肉测试测力计用于测量膝关节伸展力量。
协方差分析，以基线特征为协变量。
总体而言，MVPA、轻度和久坐活动分别占 CEV 时间的 53.73%、41.10%和 5.23%。高强度组（n=61）的主导手握力（p=0.004）和日常生活中的 MVPA 百分比（p=0.044）均高于非高强度组（n=52）。
CEV 为老年人提供了充足的身体活动机会。高强度 CEV 与更大的握力有关，但与下肢力量无关。需要进一步研究以确定 CEV 与健康变量之间的因果关系。
