中长跑等耐力项目的运动员,在极量运动时表现出来的心肺功能水平对了解运动项目的特点、选拔运动员和评定运动员的训练状态等均有重要意义。近年来,各国学者比较一致公认最大摄氧量是反映运动员心肺功能水平高低的一个主要指标。 我们对我国少年中长跑运动员进行了多年系统的观察和检查。本文就少年运动员的最大摄氧量及其影响因素,达最大摄氧量时心肺功能指标的变化进行一些探讨,以便了解剧烈运动负荷对少年机体的影响,为选择测定少年心肺功能水平的指标以及合理安排少年的运动训练等方面提供某些生理依据。 Long-distance runners and other endurance athletes, cardiopulmonary exercise performance in extreme sports to understand the characteristics of sports, selection of athletes and assess the training of athletes are important. In recent years, scholars across the world have agreed that the maximum oxygen uptake is a major indicator of the level of cardiopulmonary function in athletes. We have conducted systematic and systematic inspections and inspections on our junior middle distance runners for many years. In this paper, the maximum oxygen uptake of juvenile athletes and its influencing factors, up to the maximum oxygen uptake of cardiopulmonary function indicators to explore some of the changes in order to understand the impact of strenuous exercise load on the juvenile body, in order to choose the indicators of adolescent cardiopulmonary function and Reasonable arrangements for sports training and other aspects of youth to provide some physiological basis.
