Arm ergometry (AE) is necessitated for individuals unable to perform leg ergometry (LE) exercise. This study explored gender differences in RPE and workload (WL) during AE and LE at submaximal target heart rates (THR).
35 healthy college-aged individuals were randomly allocated to begin exercise on either AE or LE. Participants exercised on both modes with increasing WL to achieve submaximal THRs of 110, 120, 130, 140 and 150 beats per minute (bpm). Factorial ANOVAs tested for differences in RPE and WL.
No significant differences were found in RPE between genders, as well as between arm and leg exercise ( > 0.001). For WL, a significant main effect was found for mode with LE greater than AE ( < 0.001), and gender, with males greater than females ( < 0.001). A significant interaction effect was also found for HR and mode, with a greater increase in WL during LE compared to AE in both genders ( = 0.001).
Exercise specialists typically prescribe exercise based on a chosen THR. The results of this study provide meaningful data on mean RPE and WL responses that a given THR elicits for ergometry. The finding of no differences in RPE between AE and LE informs the clinician that at any given submaximal THR, similar RPE scores can be expected during AE and LE. Further research is warranted to investigate differences in wider populations.
对于无法进行腿部测力计（LE）运动的个体，手臂测力计（AE）运动是必要的。本研究探讨了在次最大目标心率（THR）下进行AE和LE运动时，主观用力程度（RPE）和工作量（WL）的性别差异。
35名健康的大学生被随机分配开始进行AE或LE运动。参与者在两种运动模式下随着工作量增加进行运动，以达到每分钟110、120、130、140和150次心跳（bpm）的次最大THR。析因方差分析测试RPE和WL的差异。
性别之间以及手臂和腿部运动之间的RPE均未发现显著差异（>0.001）。对于WL，发现运动模式有显著的主效应，LE大于AE（<0.001），性别也有显著主效应，男性大于女性（<0.001）。还发现心率和运动模式有显著的交互效应，与AE相比，男女在LE期间WL的增加幅度更大（=0.001）。
运动专家通常根据选定的THR来规定运动。本研究结果提供了关于给定THR引起的平均RPE和WL反应的有意义数据。AE和LE之间RPE无差异的发现告知临床医生，在任何给定的次最大THR下，AE和LE期间可预期有相似的RPE分数。有必要进行进一步研究以调查更广泛人群中的差异。
