摘要

Previously we have demonstrated that an accelerated arm ergometry testing protocol results in a higher peak oxygen consumption than continuous or discontinuous protocols reported in the literature (Brit. J. Sports Med. 20: 25-26, 1986). The purpose of this investigation was to determine if an accelerated protocol was superior to two commonly used protocols in cycle ergometry. Nine 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 70 W with the power output (PO) being increased 35 W.min-1. The DT began at a work rate of 70 W; the work rate was increased by 35 W every 2 minutes with 2-minutes rest between stages. The JMT began with a 3-minute pretest to determine a PO which elicited a HR of 145 +/- 5 bpm. After a 2-minute rest, subjects began exercise at the predetermined work rate with the PO being increased 35 W.min-1. Testing sessions were terminated when subjects failed to maintain the desired PO. No significant difference (p greater than 0.05) existed in peak PO or peak oxygen consumption (VO2) between the three protocols. However, JMT protocol did result in a shorter time to exhaustion than the other protocols employed (P less than 0.05).

Sports Med。20:25-26,1986)。这项研究的目的是确定在循环测功中加速方案是否优于两种常用方案。九名男性受试者接受了三种不同运动方案的测试;不连续测试(DT),连续测试(CT)和新提议的“最大跳跃测试”(JMT)。 CT以70 W的工作速率开始,功率输出(PO)增加了35 W.min-1。 DT的工作速率为70 W;每2分钟将工作效率提高35 W,阶段之间要休息2分钟。 JMT从3分钟的预测试开始,以确定引起145 +/- 5 bpm的HR的PO。休息2分钟后,受试者开始以预定的工作速率运动,同时PO升高35 W.min-1。当受试者未能维持所需的PO时,测试会议终止。三种方案之间的PO峰值或耗氧量(VO2)没有显着差异(p大于0.05)。但是,JMT协议确实比其他协议所用的时间更短(P小于0.05)。
