为了确定过度训练的客观指标,我们有意识地对4名长跑运动员在两周正常训练中增加了4次大强度的间歇训练课,从而造成运动员的过度训练。在过度训练前二周、过度训练期间和过度训练后两周进行了实验资料的(?)集。测定了睡眠状态、训练过程中的心率,5000米的检查性记时测验,每周进行一次跑台上的最大氧耗、心率和最高血乳酸的测定。另外还测定了静脉血中游离睾酮、肾上腺皮质素,肌酸(?)酸激酶(CPK)。对所有测试结果进行了多重统计学比较,结果(平均±标准差)如下:
In order to determine objective indicators of over-training, we consciously added 4 intensive training sessions to 4 long-distance runners during the two-week normal training, resulting in over-training of athletes. The (?) Set of experimental data was conducted two weeks prior to over-training, during over-training, and two weeks after over-training. Measurements of sleep status, heart rate during training, an examination of the chrono-meter of 5,000 meters, weekly maximum oxygen consumption, heart rate and maximum blood lactate determination were performed. In addition, free testosterone, adrenocortical, and creatine kinase (CPK) were also measured in venous blood. Multivariate statistical analyzes were performed on all test results. The results (mean ± standard deviation) were as follows:
