Related Data for: A case study to overcome barriers and enhance motivations through experience of a variety of exercises: Theory-based intervention on an overweight and physically inactive adult

A 5-month exercise intervention using self-determination theory was conducted for a physically inactive male adult with a body mass index >25 kg/m2 to overcome perceived exercise barriers and increase autonomous motivation to exercise through a variety of exercise programs. The participant underwent three different forms of exercise programs: trainer guided, self-guided via YouTube channels, and accustomed exercises for 3 hr weekly. The participant completed a questionnaire and body mass index measurement at baseline and during the second, fourth, and fifth months of intervention and kept an exercise log throughout the 5 months. Consultations were conducted during the second and fourth months. At the end of the program, a semistructured interview was conducted. The data showed that psychological needs satisfaction, autonomous motivation, and exercise behavior had improved, while perceived barriers had decreased. This case study provides insight into how a theory-based intervention could effectively promote exercise behavior by targeting psychological factors.

本研究针对一名体重指数（Body Mass Index, BMI）>25 kg/m²的身体活动不足男性成人，开展了一项基于自我决定理论（Self-Determination Theory）的5个月运动干预，旨在通过多种运动项目帮助其克服感知到的运动障碍，并提升运动自主动机。该参与者每周进行3小时的三种不同形式运动：教练指导、通过YouTube频道自主指导及习惯化运动。参与者在干预基线期、第2个月、第4个月及第5个月完成问卷调查与体重指数测量，并在整个5个月期间持续记录运动日志。干预第2个月和第4个月进行了咨询，项目结束时开展了半结构化访谈。数据显示，其心理需求满足感、自主动机及运动行为均有所改善，而感知到的运动障碍则有所减少。本案例研究为基于理论的干预如何通过靶向心理因素有效促进运动行为提供了见解。
