This study examined the relationship between unselected first-year medical students' knowledge and attitudes about health or exercise and their personal physical fitness. The 131 subjects performed a maximal exercise test to determine physical fitness by measuring maximal oxygen consumption (VO2max), underwent hydrostatic weighing to assess body fat content (percent body fat), and completed a questionnaire to measure their knowledge and attitudes about health promotion/disease prevention and exercise. Many independent variables were significantly associated with VO2max in bivariate analyses, but only percent body fat, resting systolic blood pressure, and perceived barriers to health promotion/disease prevention and to exercise were significant predictors of VO2max (mL x kg-1 x min-1) in the multivariate analyses. The absolute VO2max (L x min-1) can be predicted from percent body fat, weight, and perceived barriers to health promotion/disease prevention. Freshmen medical students' attitudes toward health promotion/disease prevention and exercise constitute one of three strong predictors of physical fitness levels and should be determined, along with percent body fat and resting systolic blood pressure, when estimating fitness levels in a medical student population.
本研究调查了未经筛选的一年级医学生关于健康或运动的知识与态度与其个人身体素质之间的关系。131名受试者进行了最大运动测试，通过测量最大耗氧量（VO2max）来确定身体素质，接受了水下称重以评估体脂含量（体脂百分比），并完成了一份问卷，以测量他们关于健康促进/疾病预防和运动的知识与态度。在双变量分析中，许多自变量与VO2max显著相关，但在多变量分析中，只有体脂百分比、静息收缩压以及对健康促进/疾病预防和运动的感知障碍是VO2max（毫升×千克-1×分钟-1）的显著预测因素。绝对VO2max（升×分钟-1）可根据体脂百分比、体重以及对健康促进/疾病预防的感知障碍进行预测。大一医学生对健康促进/疾病预防和运动的态度是身体素质水平的三个重要预测因素之一，在评估医学生群体的身体素质水平时，应与体脂百分比和静息收缩压一起确定。
