Physical activity (PA) is essential for physical, mental, and emotional health; however, few adults engage in enough PA. Group exercise environments such as CrossFit can promote sustained exercise habits through social influence, support, and norms. This cross-sectional study aims to provide evidence for PA social influence at CrossFit. CrossFit members ( = 62) reported PA, workout logging frequency, and members at their gym they: (1) work out with and (2) go to with personal matters. Separate linear network autocorrelation models (LNAMs) determined if individuals reported similar PA scores as those of their social ties at CrossFit that they work out with and/or those they go to for personal matters. Participants reported a mean of 2740.55 MET minutes/week (SD = 1847.08), working out with a mean of 9.89 members (SD = 6.26), and speaking to a mean of 2.66 members about personal matters (SD = 3.68). A person's PA was significantly associated with that of their ties they go to with personal matters (PE = 0.08, SE = 0.02), but was not associated with the PA of their ties they work out with (PE = 0.02, SE = 0.01). Social influence on PA levels was present when a deeper connection is made between members. Fostering and promoting deeper connections between members may help promote PA and continued exercise habits.
身体活动（PA）对身心健康至关重要；然而，很少有成年人进行足够的身体活动。团体运动环境，如 CrossFit，可以通过社会影响、支持和规范来促进持续的运动习惯。本横断面研究旨在为 CrossFit 的 PA 社会影响提供证据。CrossFit 会员（n = 62）报告了 PA、锻炼记录频率以及他们在健身房与：（1）一起锻炼和（2）一起处理个人事务的成员。分别的线性网络自相关模型（LNAMs）确定个体是否报告与他们在 CrossFit 一起锻炼和/或一起处理个人事务的社会关系具有相似的 PA 得分。参与者报告的平均每周 2740.55 MET 分钟（SD = 1847.08），平均与 9.89 名成员一起锻炼，平均与 2.66 名成员谈论个人事务（SD = 3.68）。一个人的 PA 与他们因个人事务而与之交往的关系成员的 PA 显著相关（PE = 0.08，SE = 0.02），但与他们一起锻炼的关系成员的 PA 无关（PE = 0.02，SE = 0.01）。当成员之间建立更深层次的联系时，PA 水平的社会影响就会显现出来。促进和促进成员之间更深层次的联系可能有助于促进 PA 和持续的锻炼习惯。
