The Effect Of Rest Period On Muscle Fatigue During Weight Plyometric Training

Basketball include a large number of rapid start and jump movements,which requires athletes to have a good explosive power,as the basis for the completion of these technical actions.Current research shows that increasing the explosive force requires increasing the maximum strength and movement speed.The traditional training method cannot meet the above two points at the same time.Therefore,a new training method has been developed for weight plyometric training,which can satisfy the increase in maximum strength.At the same time,the speed of movement is also increased to achieve the purpose of increasing explosive power.However,there is no clear conclusion about the training intensity of weight plyometric training,especially the study of the time between breaks.This study aims to explore the effect of different breaks on muscle fatigue of the lower extremities of the athletes by measuring the weight plyometric training tests between the different groups of basketball players in order to find the appropriate time between breaks for the sake of scientific future.Training provides some reference and help.This article will study the aerobic capacity and muscle fatigue of basketball players,and record the data of the whole experimental process through surface electromyography,near-infrared spectroscopy,and force-measuring systems,and analyze the results for the sake of future athletes.Training provides a certain reference.In this study,10 high-level men's basketball team members of Dalian University of Technology were selected as the study subjects.Ten athletes were subjected to a weight-bearing jump test during the rest time using surface electromyography,near-infrared spectroscopy,and a force measuring system to record the lower extremities.The electromyography signals of major muscles,changes in muscle oxygen saturation during exercise and recovery,and mechanical parameters of weight-bearing jump movements were calculated and analyzed.1.During the weight plyometric training test with different resting time between groups,the electromyography intensity of the surface myoelectric signals did not vary among the groups,but there was no significant difference on the whole;the average power frequency of the soleus muscles was 1 minute.There was a significant downward trend in the rest period between groups,and the mean power frequency of other measured muscles varied from group to group,but there was no significant difference overall.2.In the weight plyometric training test with different resting time between groups,the muscle oxygen saturation of the near-infrared spectrum showed a significant downward trend with the increase of the number of jumps in the exercise phase,but no minimum value appeared;the muscle oxygen saturation in the recovery phase Showing a rapid upward trend,the subjects can basically recover to the pre-exercise level within 1 minute,indicating that the rest time between the groups can meet the needs of muscle recovery.3.In the weight plyometric training with different resting time between groups,the peak force of mechanical parameters,ground contact time and average power group did not show any difference.The results of the athletes' indicators are different.The coaches can formulate suitable training programs according to the characteristics of each athlete.In addition,it can also provide references for the monitoring and evaluation of sports training.
