Maximal work capacity and aerobic fitness of wheelchair-confined subjects generally have been determined by one of three modes of exercise: wheelchair ergometry, wheelchair exercise on a treadmill (TM), and arm crank ergometry. In the present study, two new types of arm ergometers, the Cybex Upper Body Exercise ergometer (CUBE) and the Schwinn Air-Dyne ergometer (SAE), have been evaluated and compared with older methods for determining aerobic capacities of wheelchair-confined subjects. Seven persons with paraplegia with lesions ranging from T-3 to L-1 and one bilateral amputee each performed four exercise tests to volitional exhaustion, on separate days, utilizing four modes of exercise. These included wheelchair exercise on a treadmill and arm exercise using a Monark arm ergometer (MAE), a CUBE, or an SAE. Peak values for oxygen consumption, heart rate, and blood lactate were similar during each type of exercise. Significant (p less than 0.05) differences were observed only in the peak values for minute ventilation (CUBE greater than MAE, SAE greater than MAE). The similarity of the maximal responses observed in this study indicates that the CUBE and SAE are comparable to TM exercise and to the MAE in assessing the aerobic capacity of wheelchair-confined subjects.
一般来说，长期依赖轮椅的受试者的最大工作能力和有氧适能是通过三种运动模式之一来确定的：轮椅测力计测试、在跑步机（TM）上进行轮椅运动以及手臂曲柄测力计测试。在本研究中，对两种新型手臂测力计，即赛百斯上肢运动测力计（CUBE）和施温空气动力测力计（SAE）进行了评估，并与用于确定长期依赖轮椅的受试者有氧能力的旧方法进行了比较。七名截瘫患者，损伤范围从T-3到L-1，以及一名双侧截肢者，每人在不同日期进行了四项运动测试，直至自愿力竭，采用了四种运动模式。这些运动模式包括在跑步机上进行轮椅运动以及使用莫纳克手臂测力计（MAE）、CUBE或SAE进行手臂运动。每种运动类型期间，耗氧量、心率和血乳酸的峰值相似。仅在分钟通气量的峰值上观察到显著（p小于0.05）差异（CUBE大于MAE，SAE大于MAE）。本研究中观察到的最大反应的相似性表明，在评估长期依赖轮椅的受试者的有氧能力方面，CUBE和SAE与跑步机运动以及MAE相当。
