Medical school can produce intense psychological distress in its students; however, there is a paucity of research exploring potential means of improving medical students' well-being.
To investigate the relationship between physical exercise and stress and quality of life (QOL) in a medical student population.
This nonrandomized, controlled, 12-week study used a survey research design. First- and second-year osteopathic medical students at the University of New England College of Osteopathic Medicine were recruited to participate in 1 of 3 groups: (1) students participating in 30-minute CXWORX (Les Mills International LTD) group fitness classes; (2) students exercising alone or with up to 2 additional partners regularly (eg, running, weight lifting), henceforth called the health-enhancement group; and (3) students in a control group who did not engage in regular exercise. Participants completed the Perceived Stress Scale survey once every 4 weeks, as well as visual analog scale surveys to assess physical, mental, and emotional QOL weekly during the course of the study. Statistical significance was defined as P<.05.
Sixty-nine participants met the inclusion criteria and completed the study protocol, with 25 in the fitness class group, 29 in the health-enhancement group, and 15 in the control group. Compared with baseline values, the fitness class group demonstrated decreased perceived stress (P=.038) and increased physical QOL (P=.007), mental QOL (P=.046), and emotional QOL (P=.004) after 12 weeks. Participants in the health-enhancement and control groups showed no statistically significant changes between baseline and week 12 for any of these parameters, with the exception of mental QOL, which improved in the health-enhancement group (P=.023).
Participation in regular group fitness classes led to a statistically significant decrease in perceived stress and an increase in physical, mental, and emotional QOL compared with exercising regularly on one's own or not engaging in regular exercise. Attending weekly group fitness classes could be a solution to improving the emotional well-being and stress level of medical students.
医学院校的学生可能会承受巨大的心理压力；然而，探索改善医学生幸福感潜在方法的研究却很匮乏。
调查医学生群体中体育锻炼与压力及生活质量（QOL）之间的关系。
这项非随机、对照、为期12周的研究采用了调查研究设计。招募了新英格兰大学整骨医学院的一年级和二年级整骨医学生，让他们参加以下3组中的一组：（1）参加30分钟CXWORX（莱美国际有限公司）团体健身课程的学生；（2）定期独自锻炼或与最多另外两名伙伴一起锻炼（如跑步、举重）的学生，以下称为健康促进组；（3）不进行定期锻炼的对照组学生。参与者每4周完成一次感知压力量表调查，并在研究过程中每周完成视觉模拟量表调查，以评估身体、心理和情绪方面的生活质量。统计学显著性定义为P<0.05。
69名参与者符合纳入标准并完成了研究方案，其中健身课程组25人，健康促进组29人，对照组15人。与基线值相比，健身课程组在12周后感知压力降低（P=0.038），身体生活质量（P=0.007）、心理生活质量（P=0.046）和情绪生活质量（P=0.004）提高。健康促进组和对照组的参与者在这些参数的基线值和第12周之间没有显示出统计学上的显著变化，但健康促进组的心理生活质量有所改善（P=0.023）。
与独自定期锻炼或不进行定期锻炼相比，参加定期团体健身课程导致感知压力在统计学上显著降低，身体、心理和情绪生活质量提高。每周参加团体健身课程可能是改善医学生情绪健康和压力水平的一种解决方案。
