Abstract

BACKGROUND

Despite the health benefits of regular physical activity, across the globe older adults represent the least active section of society.

PURPOSE

The GrOup-based physical Activity for oLder adults (GOAL) trial was a three-arm parallel randomized controlled trial (RCT) that was designed to test the efficacy of two group-based exercise programs for older adults, informed by self-categorization theory (SCT), in comparison to a standard group-based exercise program.

METHODS

RCT conducted in Greater Vancouver, Canada, enrolled 627 older adults (Mage = 71.57 years, SD = 5.41; 71.0% female). Participants were randomized to similar age same gender (SASG), similar age mixed gender (SAMG), or 'standard' mixed age mixed gender (MAMG) exercise group conditions. In addition to group composition, the intervention programs operationalized principles from SCT designed to foster a sense of social connectedness among participants. The primary outcome of the trial was exercise adherence behavior over 12 and 24 weeks.

RESULTS

Analyses of variance revealed that older adults randomized to the SAMG (12-weeks d = .51, p < .001; 24-weeks d = .47, p < .001) and SASG (12-weeks d = .28, p = .012; 24-weeks d = .29, p = .016) conditions adhered to a greater extent than those in the MAMG comparison condition. There were no significant differences between the SAMG and SASG conditions.

CONCLUSIONS

The results provide support for the efficacy of group-based physical activity programs informed by SCT. Furthermore, the results suggest that community group-based exercise programs should attempt to engage in age-targeting but not necessarily gender-targeting among older adults.

摘要

背景

尽管有规律的身体活动对健康有益，但在全球范围内，老年人是社会中最不活跃的群体。

目的

基于团体的老年人身体活动（GOAL）试验是一项三臂平行随机对照试验（RCT），旨在测试两种基于团体的运动方案对老年人的功效，这两种方案基于自我分类理论（SCT），并与标准基于团体的运动方案进行比较。

方法

该 RCT 在加拿大大温哥华进行，招募了 627 名老年人（平均年龄 = 71.57 岁，标准差 = 5.41；71.0%为女性）。参与者被随机分配到相似年龄同性别的组（SASG）、相似年龄异性别的组（SAMG）或“标准”混合年龄混合性别的组（MAMG）运动组条件。除了团体组成外，干预方案还实施了 SCT 的原则，旨在促进参与者之间的社会联系感。试验的主要结果是 12 周和 24 周的锻炼依从性行为。

结果

方差分析显示，随机分配到 SAMG（12 周 d =.51，p <.001；24 周 d =.47，p <.001）和 SASG（12 周 d =.28，p =.012；24 周 d =.29，p =.016）条件的老年人比 MAMG 比较条件的老年人更遵守锻炼计划。SAMG 和 SASG 条件之间没有显著差异。
