Study On The Test And Application Of Body Function State And Body Quality Index Of Fujian Elite Rowing Athletes During Winter Training

Research purposes: This study takes the elite rowers in Fujian Province as the research object,and takes the hemoglobin,creatine kinase,blood urea,testosterone,cortisol,body fat rate,blood lactic acid,strength and endurance of male and female rowers in the winter training cycle of 2020-2021 as the detection indexes,The purpose of this study is to explore the changes of blood lactic acid of male and female rowers in single rowing 16 km before and after the experiment and the influence of winter training on the physical function of the athletes,and reveal the characteristics of the changes of physical fitness,so as to evaluate the scientific effectiveness of the stage training plan in real time,intervene and adjust it in time,provide the basis and data for the coaches to control the training process scientifically,and continuously improve the efficiency of preparation training,Improve the competitive level.Research objects and methods: the research objects are 24 rowers of Fujian rowing team preparing for the National Games of Shaanxi Province.This study adopts the methods of literature review,expert interview,mathematical statistics,tracking observation and experimental test.The results and conclusion are as followsResearch results:1.After winter training,the results of single rowing 16 km test of male and female rowers improved.After two 16 km long distance rowing tests,the blood lactic acid had a downward trend in the recovery period.2.The hemoglobin value of male rowers after winter training was significantly higher than that in winter training,with significant difference(P < 0.05).Compared with before winter training,the hemoglobin test value in winter training has a downward trend,but there is no significant difference(P > 0.05).The hemoglobin test value of female rowers after winter training is significantly higher than before winter training,with significant difference,P < 0.05.The CK value of male rowers in winter training was significantly lower than that before winter training,with significant difference(P < 0.05).The CK value of male rowers after winter training was significantly lower than that in winter training,with significant difference(P < 0.05);The value of CK of female rowers in winter training has a downward trend compared with that before winter training,but it is not obvious.The value of CK of female rowers after winter training has a significant increase compared with that in winter training,with significant difference(P < 0.05).The blood urea value of male rowers in winter training was significantly higher than that before winter training(P < 0.05);The blood urea value of female rowers increased significantly after winter training compared with that before winter training(P < 0.05).The testosterone level of male rowers in winter training was significantly higher than that before winter training(P < 0.05);Compared with the winter training,the testosterone value after winter training has an upward trend,but there is no significant difference(P > 0.05).The testosterone value of female rowers after winter training is significantly higher than that before winter training,with significant difference,P < 0.05.The cortisol value of male rowers after winter training was significantly lower than that in winter training(P < 0.05);The cortisol value of female rowers after winter training was significantly lower than that in winter training,with significant difference(P < 0.05).During the whole winter training period,the body fat rate of male and female rowers showed a gradual downward trend.There was a significant difference between the body fat rate before and after winter training(P < 0.05).The body fat rate of male and female rowers after winter training decreased significantly compared with that before winter training(P < 0.05).The maximum strength and strength endurance of male and female rowers increased significantly after winter training compared with that before winter training(P < 0.05).The maximum squat strength of male and female rowers increased to a certain extent,but there was no significant difference.The maximum strength and strength endurance of male and female rowers increased significantly after winter training compared with that before winter training(P < 0.05).Conclusion:3.Characteristics of body function state changeIn the whole winter training,the function of athletes is in good condition,which is in line with the adaptation stage of the research process of human physiology.The results showed that the athletes showed obvious stimulus depth response and good recovery state to the training load.The hemoglobin level of male and female rowers did not decrease due to training fatigue,and there was no significant recovery.There were not too many index characteristics of breaking their own mechanical state and reestablishing a higher functional level;From the perspective of endocrine level,the blood testosterone level and cortisol level of athletes have increased progressively in the three tests.4.Change characteristics of physical fitness indexesThe results show that the maximum strength of horizontal pull,the maximum strength of horizontal push,the endurance of horizontal pull and the endurance of horizontal push of male and female rowers increase.In the whole winter training,the body fat of male and female athletes decreased and their weight was stable,and their strength quality reached a high level;The results of long-distance water rowing test improved,blood lactic acid index decreased and aerobic capacity increased;During the winter training,the training load is arranged reasonably,and the athletes maintain a good physical function and achieve the predetermined physical fitness training goal.
