The purpose of this study was to investigate the effect of three levels of work intensity on the performance of a fine motor skill during steady-state exercies. Subjects were administered a progressive bicycle ergometer test to exhaustion in order to determine maximum heart rate (HRmax). Following practice sessions on the pursuit rotor, subjects performed 3 different rides on a bicycle ergometer at 60, 75, and 90% of HRmax. The order to test administration was varied randomly in an attempt to control for sequential effects. Analysis of variance with repeated measures was used to determine differences in pursuit rotor performance by days and by levels of work intensity. No confounding of learning was noted. A significant F ratio (p less than .001) between work intensities showed that fine motor performance during steady-state exercise is affected by levels of work intensity.
本研究的目的是调查三种工作强度水平对稳态运动期间精细运动技能表现的影响。对受试者进行递增式自行车测力计测试直至 exhaustion，以确定最大心率（HRmax）。在追踪转子上进行练习后，受试者在自行车测力计上以 HRmax 的 60%、75%和 90%进行了 3 次不同的骑行。测试管理的顺序随机变化，以试图控制顺序效应。使用重复测量的方差分析来确定追踪转子表现按天数和工作强度水平的差异。未发现学习的混淆因素。工作强度之间显著的 F 比率（p 小于 0.001）表明，稳态运动期间的精细运动表现受工作强度水平的影响。
