Abstract

Seven female and eight male elite junior skaters performed cycle ergometer tests at four different times during the 1987/1988 season. The tests consisted of a Wingate-type 30-s sprint test and a 2.5-min supramaximal test. The subjects were tested in February, May and September 1987 and in January 1988. Maximal oxygen consumption was measured during the 2.5-min test. With the exception of the maximal oxygen consumption of the women in May which was about 6% lower than in the other three tests, no seasonal changes in the test results could be observed--this, in spite of a distinct increase in training volume (from 10 to more than 20 h.week-1) and training intensity in the course of the season. When the test data were compared to those of elite senior skaters, it appeared that the junior skaters showed the same values for mean power output during the sprint test [14.2 (SD 0.4) W.kg-1 for the men and 12.6 (SD 0.5) W.kg-1 for the women] and maximal oxygen consumption [63.1 (SD 2.8) ml.kg-1.min-1 for the men and 55.3 (SD 3.5) ml.kg-1.min-1 for the women, respectively] as found for senior skaters. It seemed, therefore, that the effects of training in these skaters had already levelled off in the period before they participated in this investigation. In contrast to previous studies, no relationship could be shown between the test results and skating performance. This was most likely due to the homogenous character of the groups (mean standard deviations in power and oxygen consumption were only 5%).(ABSTRACT TRUNCATED AT 250 WORDS)

摘要

1987/1988赛季期间,7名精英青年女滑冰运动员和8名精英青年男滑冰运动员在四个不同时间进行了自行车测力计测试。测试包括一次温盖特式30秒冲刺测试和一次2.5分钟超最大测试。受试者分别在1987年2月、5月、9月以及1988年1月接受测试。在2.5分钟测试期间测量最大耗氧量。除了5月份女性的最大耗氧量比其他三次测试低约6%外,未观察到测试结果有季节性变化——尽管在赛季过程中训练量(从每周10小时增加到超过20小时)和训练强度明显增加。当将测试数据与精英成年滑冰运动员的数据进行比较时,发现青年滑冰运动员在冲刺测试中的平均功率输出值[男性为14.2(标准差0.4)瓦·千克-1,女性为12.6(标准差0.5)瓦·千克-1]和最大耗氧量[男性为63.1(标准差2.8)毫升·千克-1·分钟-1,女性为55.3(标准差3.5)毫升·千克-1·分钟-1]与成年滑冰运动员相同。因此,似乎这些滑冰运动员的训练效果在他们参加本次调查之前的时期就已经趋于平稳。与先前的研究不同,测试结果与滑冰成绩之间没有显示出相关性。这很可能是由于这些组的同质性(功率和耗氧量的平均标准差仅为5%)。(摘要截选至250词)
