Spiroergometry is important for modern performance diagnostics, and reference values have been evaluated for bicycle and treadmill ergometers. The aim of this study is to assess the comparability of bicycle and hand-crank spiroergometry and its associated parameters, as hand-crank spiroergometry can be used during rehabilitation in patients with definitive or temporally impairment of the lower extremity.
Thirty-seven healthy volunteers completed 2 exhausting performance diagnostics on hand-crank and bicycle spiroergometry. Participants' anthropometric characteristics, maximum power, multiple exertion criteria, maximum aerobic capacity, and maximum heart rate were detected, and ventilatory and metabolic thresholds were determined.
The maximum power, maximum heart rate, maximum aerobic capacity, and ventilatory thresholds were significant higher on the bicycle ergometer (P < .001). The metabolic thresholds occurred on higher lactate values on the hand-crank ergometer. Equations for calculating maximum aerobic capacity from the maximum power measured in either hand-crank or bicycle ergometer could be found through regression analysis.
Although there are problems in interpreting results of different ergometries due to severe physiology differences, the equations can be used for patients who are temporally unable to complete the established ergometry due to a deficit in the lower extremity. This could improve training recommendations for patients and para-athletes in particular.
运动心肺功能测试对现代运动表现诊断很重要，且已针对自行车和跑步机测力计评估了参考值。本研究的目的是评估自行车和手摇运动心肺功能测试及其相关参数的可比性，因为手摇运动心肺功能测试可用于下肢有明确或暂时损伤的患者的康复过程中。
37名健康志愿者完成了手摇和自行车运动心肺功能测试的2次力竭性运动表现诊断。检测了参与者的人体测量学特征、最大功率、多项运动标准、最大有氧能力和最大心率，并确定了通气和代谢阈值。
自行车测力计上的最大功率、最大心率、最大有氧能力和通气阈值显著更高（P <.001）。手摇测力计上的代谢阈值出现在更高的乳酸值时。通过回归分析可以找到根据手摇或自行车测力计中测得的最大功率计算最大有氧能力的方程。
尽管由于严重的生理差异，在解释不同测力计的结果时存在问题，但这些方程可用于因下肢缺陷暂时无法完成既定测力计测试的患者。这尤其可以改善对患者和残疾运动员的训练建议。
