The aim of this study was to examine the effects of aging on perceived exertion (PE) and perceived arm pain (PaP) at the end of a maximal graded arm test in 70- to 80-year -old women. Twelve healthy young (mean age 22.9 ± 3.3 years), and 12 healthy elderly (mean age 74.6 ± 3.7 years) women performed a maximal graded test (GXT) on an arm crank ergometer until exhaustion. The results revealed no significant difference between both groups concerning PE (p > 0.05; Effect Size = 0.62) and when heart rate (HR) was expressed as a theoretical maximal heart rate (THRmax) (p > 0.05; Effect Size = 0.17). Nevertheless, PaP was significantly lower (p < 0.05; Effect Size = 2.95) in the elderly compared to the young group. In conclusion, these results suggest that, at the end of GXT, PE is not influenced, whereas PaP may be altered by aging of the women tested in the present study. Therefore, it appears difficult to use PaP in these elderly women to regulate exercise intensity during a training program. Key PointsAt the end of a maximal graded arm test, perceived exertion is not influenced, whereas perceived arm pain may be altered by aging.It appears difficult to use perceived arm pain in elderly women to regulate exercise intensity during a training program.
本研究旨在探讨衰老对 70-80 岁女性最大分级手臂测试结束时感知用力（PE）和感知手臂疼痛（PaP）的影响。12 名健康年轻女性（平均年龄 22.9 ± 3.3 岁）和 12 名健康老年女性（平均年龄 74.6 ± 3.7 岁）在手摇曲柄测功计上进行最大分级测试（GXT），直至力竭。结果表明，两组之间的 PE（p > 0.05；效应大小= 0.62）和当心率（HR）表示为理论最大心率（THRmax）时（p > 0.05；效应大小= 0.17）无显著差异。然而，与年轻组相比，老年组的 PaP 明显较低（p < 0.05；效应大小= 2.95）。结论：这些结果表明，在 GXT 结束时，PE 不受影响，而 PaP 可能因本研究中测试的女性衰老而改变。因此，在这些老年女性中，使用 PaP 来调节训练计划期间的运动强度似乎很困难。关键点在最大分级手臂测试结束时，感知用力不受影响，而感知手臂疼痛可能因衰老而改变。在训练计划期间，使用老年女性的感知手臂疼痛来调节运动强度似乎很困难。
