Known for its ability to improve fitness and health, high-intensity functional training (HIFT) focuses on functional movements completed at high intensities, often yielding outcomes superior to repetitive aerobic workouts. Preference for and tolerance of high-intensity exercise are associated with enjoyment of and adherence to HIFT. Similarly, the social environment present within CrossFit, a popular group-based HIFT modality, is important to the enjoyment of and adherence to HIFT. This study aimed to test whether preference and tolerance were related to social connections within CrossFit networks. Linear network autocorrelation models (LNAMs) and exponential random graph models (ERGMs) were computed on sociometric and attribute data from members of three CrossFit networks (n = 197). LNAMs showed the preference and tolerance scores of someone's social connections were associated with their own in all three gyms, and ERGMs demonstrated preference and tolerance scores were associated with the presence of social ties within all networks. This study is the first to provide evidence for a relationship between social connections and preference and tolerance. Future longitudinal research is needed to determine if the social environment may influence and optimize a person's preference of and tolerance for HIFT.
高强度功能性训练（HIFT）以提高健康和健身水平而闻名，其专注于高强度完成的功能性运动，其结果通常优于重复性有氧运动。对高强度运动的偏好和耐受性与对 HIFT 的享受和坚持有关。同样，在流行的基于团体的 HIFT 模式 CrossFit 中，社交环境对于享受和坚持 HIFT 也很重要。本研究旨在测试偏好和耐受性是否与 CrossFit 网络中的社交关系有关。使用来自三个 CrossFit 网络的成员的社会计量学和属性数据，计算了线性网络自相关模型（LNAMs）和指数随机图模型（ERGMs）（n = 197）。LNAMs 表明，在所有三个健身房中，某人社交关系的偏好和耐受性得分与他们自己的偏好和耐受性得分有关，而 ERGMs 则表明，偏好和耐受性得分与网络内的社交关系存在有关。这项研究首次提供了社交关系与偏好和耐受性之间存在关系的证据。需要进行未来的纵向研究，以确定社交环境是否会影响和优化个人对 HIFT 的偏好和耐受性。
