Peak physiological capabilities are necessary for top level performance in sports, although skills and motivation play an important role. Laboratory assessments often give us valuable insights concerning the physiological factors underlying athletic performance. The Physical Fitness Index (PFI) determined by the Harvard Step Test (HST) is one of the most important indexes which predicts the physical abilities of athletes. HST, Cooper's 12-min run-walk test and one-mile run are good measures of cardiorespiratory fitness. In the present study, we have attempted to determine the relationship between HST and the one-mile run in an open field on 31 school boys of a rural village, 14-15 years of age, who were in early puberty. The mean HST score was 90 +/- 7.07, and one-mile running time was 443.45 +/- 29.82 s. There is a good correlation between HST and running time (r = 0.94). Probable running time for one-mile may be determined from the HST score by using the regression equation: Running time in s = 783 - 4* HST +/- 0.13 (SE of estimate).
尽管技能和动机起着重要作用，但巅峰生理能力对于体育顶级表现而言是必要的。实验室评估常常能让我们深入了解运动表现背后的生理因素。通过哈佛台阶试验（HST）测定的体能指数（PFI）是预测运动员体能的最重要指标之一。HST、库珀12分钟跑走测试和一英里跑都是心肺适能的良好衡量指标。在本研究中，我们试图确定14 - 15岁处于青春期早期的某乡村31名男学生的HST与在开阔场地进行的一英里跑之间的关系。HST平均得分是90±7.07，一英里跑时间是443.45±29.82秒。HST与跑步时间之间存在良好的相关性（r = 0.94）。可使用回归方程根据HST得分确定一英里的可能跑步时间：跑步时间（秒）= 783 - 4×HST±0.13（估计标准误） 。
