Poor physical fitness of wheelchair-dependent individuals may result in excessive cardiorespiratory responses during locomotion. The purpose of this study was to develop and implement an interval training program (ITP) incorporating wheelchair ergometer (WERG) exercise to improve fitness for wheelchair activity. Of thirteen able-bodied female volunteers, seven were selected to participate in a 5-week ITP, while the remainder served as sedentary controls. Both the exercise training (ET) group and the sedentary control (SC) group completed a standardized fitness test on the WERG before (pre-test) and after (post-test) the 5-week period. Following the ITP, submaximal heart rate, pulmonary ventilation and oxygen uptake responses of the ET group were generally found to be significantly lower during the post-test. These improvements in WERG exercise performance were not observed in the SC group. The ITP may have contributed to adaptations of upper body muscles, improved cardiorespiratory function, and/or a higher level of skill for wheelchair propulsion. We conclude that applying the concepts of interval training to wheelchair exercise may substantially improve the performance and fitness characteristics of wheelchair users. This could reduce the relative stresses of wheelchair locomotion and lead to a higher level of rehabilitation.
依赖轮椅的个体身体素质较差可能导致运动过程中心肺反应过度。本研究的目的是制定并实施一项包含轮椅测力计（WERG）运动的间歇训练计划（ITP），以提高轮椅活动的适应性。在13名身体健康的女性志愿者中，7人被选中参加为期5周的ITP，其余作为久坐对照组。运动训练（ET）组和久坐对照（SC）组在为期5周的时间段前后（预测试和后测试）均在WERG上完成了标准化适应性测试。在ITP之后，一般发现ET组在测试后的次最大心率、肺通气和摄氧量反应显著降低。SC组未观察到WERG运动表现的这些改善。ITP可能有助于上身肌肉的适应性、改善心肺功能和/或提高轮椅推进技能水平。我们得出结论，将间歇训练的概念应用于轮椅运动可能会显著改善轮椅使用者的表现和适应性特征。这可以降低轮椅运动的相对压力，并带来更高水平的康复效果。
