在这项课题中,共选定112名从事耐力项目的运动员参加,按其年龄分成3个组。任意选定32名受试者(每个年龄组11名)参加实验室和场地两项无氧阈测试。在实验室和场地两种条件下,无氧阈出现时其相关系数介于0.82～0.90之间,且与年龄最大组的关系更加密切。所有运动员参加不同距离的一系列比赛,测出无氧阈跑速与真正比赛时的跑速的关系。经测试发现,距离为5公里及5公里以上时,无氧阈跑速同比赛跑速密切相关,其中12～18岁和19～30岁年龄组的10公里跑以及年龄最大组的1小时跑,无氧阈跑速同比赛跑速的关系最为密切。短距离跑(例如800米)显示不出与无氧阈跑速的密切关系,年龄最大组对此表现得尤为明显(R=0.30)。
In this issue, a total of 112 athletes engaged in endurance projects were selected and divided into three groups according to their age. Thirty-two subjects (11 in each age group) were randomly selected to participate in two anaerobic threshold tests in laboratories and venues. Under the two conditions of laboratory and field, the correlation coefficients of anaerobic thresholds ranged from 0.82 to 0.90, and were more closely related to the oldest group. All athletes participated in a series of competitions at different distances and measured the relationship between the anaerobic threshold running speed and the actual running speed. The test found that at a distance of 5 km and 5 km above, the anaerobic threshold running speed is closely related to the race speed, of which 12 to 18 years and 19 to 30 years of age 10 km run and the oldest group of 1 hour run, The anaerobic threshold running speed is most closely related to the running speed. Short distance runs (eg 800 meters) did not show a close relationship with the anaerobic threshold running speed, especially for the oldest group (R = 0.30).
