Characteristics of Heart Rate Changes of Elite Sprinters during Speed Training

摘要

Objective:To infer the training load from the characteristics of heart rate changes of elite sprinters during maximum intensity training.Methods:Different training loads were determined according to different running distances.Multi-person running in the same group was used to collect the heart rate data of elite sprinters during speed training.Results:the heart rate level was directly related to the exercise load.During the maximum intensity exercise,the heart rate generally increased for about 12 s after the race,which was about 110%of the end-point heart rate.Compared with the low load group(60m),the heart rate of the high load group(100m)continued to rise,but the maximum heart rate level was higher than that of the low load group.The exercise intensity and heart rate change rate of the low load group are greater,the work done by the high load group is more,and the envelope area of the heart rate curve is larger.During intermittent training,under the condition of controlling the interval between groups,the heart rate curve envelope area of the low load group is small,the physical recovery is good,the parameter consistency of each group is good,the heart rate curve envelope area of the high load group is large,and the heart rate response decreases gradually.
