To evaluate the impact of a curricular intervention to promote health-related fitness (HRF) among medical students in Bogota, Colombia.
The study was conducted between May 2014 and December 2015 as part of the medical physiology course, in which 208 medical students were enrolled.The curricular intervention included two lectures on physical activity (PA) and student-led group presentations on the physiological effects of exercise on human physiology. An academic incentive (10% of final grade) was given to students who reported and documented regular PA practice during the semester. This study assessed students' HRF variables, perceptions of the curriculum intervention, and PA practices using quantitative and qualitative approaches.
55% of the students were female, with a mean age of 19.5 years. Body fat, estimated maximum oxygen consumption (VO2max), handgrip, and sit-up strength showed statistically significant improvements at the end of the intervention. Students reported that PA practice was positively influenced by the curriculum intervention, particularly the academic incentive and the HRF tests. Students reported a wide variety of PA practices, which were mainly done with friends, classmates, or family members. Lack of time was the main reported barrier to PA practice.
The curricular intervention was effective in improving HRF and promoting PA. It remains to be investigated whether these gains are sustained over time.
评估在哥伦比亚波哥大开展的一项课程干预措施对医学生健康相关体适能（HRF）的影响。
该研究于 2014 年 5 月至 2015 年 12 月期间在医学生理学课程中进行，共有 208 名医学生参与。课程干预包括两次关于体力活动（PA）的讲座和学生主导的小组报告，介绍运动对人体生理学的生理影响。对于在学期内报告并记录有规律的 PA 实践的学生，给予学术激励（总成绩的 10%）。本研究采用定量和定性方法评估学生的 HRF 变量、对课程干预的看法以及 PA 实践情况。
55%的学生为女性，平均年龄为 19.5 岁。干预结束时，体脂肪、估计最大摄氧量（VO2max）、握力和仰卧起坐力量均有统计学意义上的显著改善。学生报告说，课程干预特别是学术激励和 HRF 测试对 PA 实践有积极影响。学生报告了各种各样的 PA 实践，主要是与朋友、同学或家人一起进行。缺乏时间是报告的主要 PA 实践障碍。
课程干预有效提高了 HRF 并促进了 PA。这些收益是否能持续下去仍有待调查。
