The reliability and concurrent validity of a simple questionnaire to assess leisure time physical activity has been investigated on 306 self-selected healthy adults of both sexes (163 M; 143 F). Values of body fat (BF) and maximum oxygen intake (VO2 max) expressed as percentiles of appropriate age and sex categories were used as criteria of validity for the questionnaire. BF and VO2 max were predicted from the Durnin and Womersley skinfold equations, and the laboratory version of the Canadian Home Fitness Test respectively. The strongest correlation was between VO2 max (percentile) and reported strenuous exercise (r = 0.35). The optimum discriminant function for VO2 max was based on a combination of reported strenuous and light activity. This yielded a correct 2-way classification of 69% of the subjects. A combination of sweat-inducing and moderate exercise yielded a correct 2-way classification of BF for 66% of subjects. The reliability coefficients for the optimum discriminant functions classifying VO2 max and BF were 0.83 and 0.85 respectively. We conclude that this simple instrument has potential value for the assessment of leisure time exercise behavior, offering the possibility of examining changes in behavior following the implementation of health and physical fitness promotion programmes in the community.
一项用于评估休闲时间体力活动的简单问卷的信度和同时效度，已在306名自行选择的健康成年男女（163名男性；143名女性）中进行了调查。以适当年龄和性别类别的百分位数表示的体脂（BF）值和最大摄氧量（VO2 max）用作该问卷效度的标准。BF和VO2 max分别根据杜宁和沃姆斯利皮褶厚度公式以及加拿大居家健身测试的实验室版本进行预测。最强的相关性存在于VO2 max（百分位数）与报告的剧烈运动之间（r = 0.35）。VO2 max的最佳判别函数基于报告的剧烈和轻度活动的组合。这使得69%的受试者得到了正确的双向分类。导致出汗的运动和适度运动的组合，使66%的受试者得到了BF的正确双向分类。对VO2 max和BF进行分类的最佳判别函数的信度系数分别为0.83和0.85。我们得出结论，这种简单的工具对于评估休闲时间的运动行为具有潜在价值，为在社区实施健康和体能促进计划后检查行为变化提供了可能性。
