To determine whether a submaximal one-arm cranking test could be used to predict an individual's upper body aerobic capacity. This issue has potential importance for the fitness assessment of individuals with neurological disease or damage who have hemiplegia.
Nine healthy male volunteers (33+/-2.4 years) and nine female volunteers (27+/-1.9 years) performed a two-arm maximal, two-arm submaximal test and a one-arm submaximal arm crank ergometry test. Heart rate (HR) was monitored via a three-lead electrocardiogram (ECG) and expired air was analysed every 30 seconds throughout Prediction of peak oxygen consumption (Vo2peak) was calculated by linear extrapolation to an age-adjusted HRpeak.
Heart rate and Vo2 were highly correlated in each test, and there were no significant differences between the Vo2peak values obtained from maximal crank ng and Vo2peak predicted from one- and two-arm submaximal tests for males and females. As expected, males were found to have significantly (p<0.001) higher actual and predicted Vo2peak values, indicating that separate regression equations should be used for males and females.
Heart rate values obtained during one-arm submaximal cranking have the potential to predict arm cranking Vo2peak, and therefore provide an estimation of an individual's aerobic capacity, in addition to those obtained from the more traditional two-arm tests.
确定次最大强度单臂手摇测试是否可用于预测个体的上身有氧能力。对于患有偏瘫的神经疾病或损伤个体的体能评估而言,该问题具有潜在的重要性。
9名健康男性志愿者(33±2.4岁)和9名女性志愿者(27±1.9岁)进行了双臂最大强度测试、双臂次最大强度测试和单臂次最大强度手摇测力计测试。通过三导联心电图(ECG)监测心率(HR),并在整个测试过程中每30秒分析一次呼出气体。通过线性外推至年龄校正后的心率峰值来计算预测的最大耗氧量(Vo2peak)。
在每项测试中,心率与Vo2高度相关,男性和女性通过最大强度手摇测试获得的Vo2peak值与通过单臂和双臂次最大强度测试预测的Vo2peak值之间无显著差异。正如预期的那样,发现男性的实际和预测Vo2peak值显著更高(p<0.001),这表明男性和女性应使用不同的回归方程。
除了从更传统的双臂测试中获得的心率值外,单臂次最大强度手摇过程中获得的心率值有可能预测手摇Vo2peak,从而提供个体有氧能力的估计值。
