本文对以上肢训练为主的15名优秀皮划艇运动员和以下肢训练为主的14名优秀中长跑运动员在两种常规负荷方式下的无氧阈及最大吸氧量进行了测定分析,以探讨训练专一性对无氧阈测定的影响。采用踏车式功量计和活动平板方式逐级递增负荷,通过与Apple Ⅱ_E辅助联机的Jaeger EOS自动分析系统,以通气和气体交换指标的变化,无创性地测定无氧阈和最大吸氧量。结果表明,训练专一性会影响无氧阈测定结果。欲测得最高的无氧阈值,实验室测试手段就应当尽量模拟训练时的运动形式。此外,能敏感地反映出运动训练专一性适应的是无氧阈时的吸氧量绝对值(1/min),而不是无氧阈的相对值(％Vo_2max)。
In this paper, 15 elite canoe athletes mainly based on upper limb training and 14 excellent middle-long-distance runners based on lower limb training were measured and analyzed under two kinds of conventional load modes, and the maximum oxygen uptake Discuss the influence of training specificity on anaerobic threshold measurement. The treadmill-type dynamometer and moving plate method were used to increase the load step by step. The Jaeger EOS automatic analysis system, which was connected with Apple Ⅱ_E, was used to noninvasively measure the anaerobic threshold and maximum oxygen uptake . The results show that training specificity affects the results of anaerobic threshold measurement. To measure the highest anaerobic threshold, laboratory tests should try to simulate the form of exercise training. In addition, the absolute value of oxygen uptake (1 / min) at anaerobic threshold, rather than the relative value of anaerobic threshold (% Vo_2max), can be sensitively reflected in the specificity of exercise training.
