The purpose of this investigation was to determine if a new proposed arm ergometer protocol was advantageous in eliciting higher peak oxygen uptake (peak VO2) when compared with two protocols currently referred to in the literature. Ten male subjects were tested on three different exercise protocols; a discontinuous test (DT), a continuous test (CT) and a new proposed jump-max test (JMT). The CT began at a work rate of 33 watts (W) (40 rpm) with the power output (PO) being increased 16 W every 3 minutes. The DT began without resistance on the ergometer flywheel (50 rpm) and the work rate was increased by 25 W every 3 minutes with a 1-minute rest between stages. The JMT began with a 3-minute pretest to determine a PO which elicited a HR of 120 +/- 5 beat min-1. After a 2-minute rest, subjects began exercise at the predetermined work rate (80 rpm) with the PO being increased 20 W each minute of the test. Oxygen uptake was measured minute by minute via open circuit spirometry. Peak VO2 was higher (p less than 0.05) in the JMT (mean +/- SEM = 2.36 +/- 0.06 l.min-1) when compared with either (means +/- SEM = 2.16 +/- 0.07 l.min-1) or the CT (means +/- SEM = 2.04 +/- 0.10 l.min-1). No difference (p greater than 0.05) existed in peak VO2 between the CT and the DT. These data suggest that the proposed JMT may result in a higher measured peak VO2 in subjects when compared with either DT or CT of moderate to long duration.
本研究的目的是确定新提出的手臂测力计方案与文献中目前提及的两种方案相比，在引出更高的峰值摄氧量（峰值VO₂）方面是否具有优势。对10名男性受试者进行了三种不同运动方案的测试；间断测试（DT）、连续测试（CT）和新提出的跳跃最大值测试（JMT）。CT以33瓦（W）（40转/分钟）的工作速率开始，每3分钟功率输出（PO）增加16 W。DT在测力计飞轮无阻力（50转/分钟）的情况下开始，每3分钟工作速率增加25 W，各阶段之间休息1分钟。JMT开始时进行3分钟的预测试，以确定能引出心率为120±5次/分钟的PO。休息2分钟后，受试者以预定的工作速率（80转/分钟）开始运动，测试期间每分钟PO增加20 W。通过开路肺量计逐分钟测量摄氧量。与DT（均值±标准误=2.16±0.07升/分钟）或CT（均值±标准误=2.04±0.10升/分钟）相比，JMT中的峰值VO₂更高（p<0.05）（均值±标准误=2.36±0.06升/分钟）。CT和DT之间的峰值VO₂无差异（p>0.05）。这些数据表明，与中长时间的DT或CT相比，所提出的JMT可能会使受试者的测量峰值VO₂更高。
