This research replicates and extends an occupational therapy research project reported by Kircher in 1984. Thirty women aged 18 to 31 years jumped with a rope on one day and jumped in place on another day in a counterbalanced design. Each subject stopped jumping when she reached what she perceived as the very hard level on the Borg Scale of Perceived Exertion (Borg, 1970). Differences from Kircher's design included an imposed target zone formula for safe maximum exertion, use of a portable, more easily read heart rate monitor (Exersentry, Model 3), use of the Osgood Semantic Differential to measure affective meanings, and asking the subjects to identify the type of jumping they preferred. Data analysis supported Kircher's finding that at the given rate of perceived exertion, heart rate increase after jumping rope was significantly higher (p = .01) than after jumping without a rope. The difference in duration of jumping approached significance (p = .06), but in the direction opposite to what Kircher found. There were no significant differences in affective meanings or preference. Results are discussed in terms of the need for a growing body of occupational therapy literature in regard to the purposefulness of activities.
本研究重复并扩展了基尔彻于1984年报告的一个职业治疗研究项目。30名年龄在18至31岁之间的女性，按照平衡设计，一天跳绳，另一天原地跳跃。每位受试者在达到她所认为的伯格主观用力程度量表（伯格，1970年）上的非常困难级别时停止跳跃。与基尔彻设计的不同之处包括用于安全最大用力的强制目标区域公式、使用便携式且更易读取的心率监测器（Exersentry，型号3）、使用奥斯古德语义分化法来测量情感意义，以及要求受试者识别她们更喜欢的跳跃类型。数据分析支持了基尔彻的发现，即在给定的主观用力程度下，跳绳后的心率增加显著高于（p = .01）无绳跳跃后的心率增加。跳跃持续时间的差异接近显著水平（p = .06），但方向与基尔彻的发现相反。在情感意义或偏好方面没有显著差异。根据职业治疗文献中关于活动目的性的不断增长的需求对结果进行了讨论。
