We examine whether adolescents’ participating in a variety of physical activities, locations, and/or with a variety of people relates to physical activity 16 months later and whether perceptions of variety mediate these relationships. Adolescents (N = 369) completed measures indicating various physical activities they participated in, where they primarily participated, and with whom they primarily participated, at three time points over a year (averaged for baseline measures). Perceptions of variety was measured 8 months later. Physical activity was measured 16 months after baseline. Mediation analyses tested perceptions of variety as a mediator of variety support and physical activity. Results indicated that variety of activities and variety of locations were indirectly associated with physical activity through perceptions of variety. Participating in a breadth of physical activities in a variety of locations during adolescence is positively associated with perceptions of variety, which relates to physical activity 16 months later.

我们研究了青少年参加各种体育活动、地点和/或与不同的人是否与 16 个月后的体育活动有关，以及对多样性的看法是否介导了这些关系。青少年 ( N = 369) 在一年内的三个时间点完成了测量，表明他们参加的各种体育活动、主要参加的地点以及主要与谁一起参加（基线测量的平均值）。 8 个月后测量了对多样性的看法。基线后 16 个月测量体力活动。中介分析测试了对多样性作为多样性支持和体育活动中介因素的看法。结果表明，活动的多样性和地点的多样性通过对多样性的感知与身体活动间接相关。青春期期间在不同地点参加广泛的体育活动与多样性感知呈正相关，这与 16 个月后的体育活动有关。
