男大学生中长跑运动员训练过程生理生化指标研究——心率恢复率、血乳酸清除率变化情况

通过实验室研究方法、文献资料法、数理统计法、综合分析法等研究方法对业余男中长跑运动员在不同训练阶段的血乳酸清除率、心率恢复率等指标进行测定，得出了不同训练阶段运动员的运动强度安排、间歇时间安排应不同的结论．运动员在训练初期运动强度要小些，间歇时间为9min左右；训练三个月后训练强度可适当加大，间歇时间调整为8min左右；当系统训练半年后由于运动员的血乳酸清除率和心率恢复率都达到了一个较高的水平，可以采用较大的训练强度，适当地缩短训练时间，将间歇时间调整为7min左右．

A Study of the Physiological Index of Male College Middle- Distance Race Athletes in Different Training Stages Changes in Heart Rate Recovery Rate, and Blood Lactate Clearance Rate

Through the methods of laboratory research, literature consultation, mathematical statistics, comprehensive analysis, etc. , this article studies the blood lactate clearance rate and heart rate recovery rate in different training stages. By measuring the blood lactate clearance rate and heart rate recovery rate, we find that athletes arrangement of intensity and intermittent time arrangements are not the same： in the initial stage, athletes exercise intensity is smaller; intermittent time is about 9min; training after three months, training intensity can be appropriately increased; intermittent time adjustment is about 8min, when the system continues to six months after training, the athletes blood lactate clearance rate and heart rate recovery rate have reached a higher level, so it can be used with larger intensity of training, appropriately to reduce the training time and the interval time can be adjusted to about 7min.
