背景：体育锻炼在整个生命周期中都对健康有益，但只有13%的加拿大老年人足够活跃。许多观察性研究的结果表明，成年人对与年龄相近、性别相同的人一起锻炼表现出积极的偏好，而组内年龄和性别相似性与锻炼依从性的提高有关。然而，研究还没有实验检验组内年龄和性别相关的相似性在多大程度上影响运动坚持行为。方法/设计：老年人群体体育活动（GOAL）试验是一项三组随机对照试验，将检验两种不同的老年人群体运动计划（根据自我分类理论的原则）与标准群体运动计划的效果。在本文中，我们概述了GOAL试验的设计和建议评价。第一组是由年龄相仿、性别相同的参与者组成的锻炼组；第二组由年龄相仿的混合性别参与者组成；对照组由混合年龄、混合性别的参与者组成。我们的目的是比较不同条件下参与者的依从率，以及潜在的调节效应和中介机制。讨论：本试验的结果将为干预设计提供信息，以改善老年人的运动坚持行为。在系统层面上，应该支持本试验中测试的干预措施的有效性，改变组组成（即年龄、性别）代表了体育活动中心的可行方案适应。
Background: Physical activity has health benefits across the lifespan, yet only 13 % of Canadian older adults are sufficiently active. Results from a number of observational studies indicate that adults display positive preferences for exercising with others of a similar age and same gender, and that intra-group age- and gender-similarity are associated with elevated exercise adherence. However, research has yet to experimentally examine the extent to which intra-group age- and gender-related similarity affect exercise adherence behaviors.Methods/design: The GrOup-based physical Activity for oLder adults (GOAL) trial is a three-arm randomized control trial that will examine the efficacy of two different group-based exercise programs for older adults (informed by the tenets of self-categorization theory) in relation to a standard group-based exercise program. Within this manuscript we outline the design and proposed evaluation of the GOAL trial. The first arm is comprised of exercise groups made up of participants of a similar-age and of the same gender; the second arm consists of groups with similar-aged mixed gender participants; the control arm is comprised of mixed-aged mixed gender participants. We aim to compare the adherence rates of participants across conditions, as well as potential moderation effects and mediating mechanisms.Discussion: Results from this trial will inform intervention designs to improve the exercise adherence behaviors of older adult. At a systems-level, should support be derived for the efficacy of the interventions tested in this trial, changing group composition (i.e., age, gender) represents a feasible program adaptation for physical activity centers.
