Monitoring And Evaluation Of TRIMP Based On Heart Rate In Chinese Women Basketball Training

Research objectives: With the transformation of China from a sports power to a sports power,sports training is scientific,science and technology to help sports,and the sports and science integration guarantee system is gradually improved.The National Women's Basketball team attaches great importance to the role of science and technology in women's basketball training and purchased a Firstbeat sports monitoring system to monitor athletes' heart rate in real time.A scientific research group was set up to carry out scientific and technological services to record the heart rate of athletes during training and competition,so as to determine the "load characteristics" of athletes and to explore the monitoring of athletes' training with heart rate as the object,so as to improve the training quality of athletes.Research methods: This paper takes 14 Chinese women's basketball players preparing for the 2019 Women's Basketball World Cup as the research object,USES Firstbeat sports monitoring device in Finland to conduct tracking test for the whole training cycle,records the quiet heart rate,daily training session and heart rate in different forms of competitions of 14 Chinese women basketball players before training.Select TRIMP calculation method as the main index to monitor the load of the movement of athletes,strength of defense,fast break,physical training,shooting,eight layup,location technology,help and roll technology training,11 games international exhibition,6 games the team teaching and session domestic actual combat to sorting and analyzing the monitoring data,fitting for the load of the movement of athletes monitoring,feedback and evaluation.Conclusion :(1)When the athletes execute the same training plan,the training load is relatively consistent.The training load of different technical training contents is from large to small in order for defense,fast break,physical training,intensity shooting,8-character layup,position technique,and defense pick-and-roll.(2)The analysis of individual TRIMP during the competition shows that the TRIMP value of athletes in upwind plate competition is higher than that in downwind plate competition.The training intensity of the teaching competition in the team cannot meet the requirement of the exercise intensity in actual combat.(3)TRIMP value is basically consistent with physiological and biochemical indexes and has a certain correlation.TRIMP reflects the change of athletes' load,and physiological and biochemical indicators reflect the athletes' response to training.The two detection methods have their respective advantages.Compared with physiological and biochemical indicators detection,TRIMP provides more convenient and timely feedback to training.TRIMP only reflects the internal load of athletes.If a comprehensive evaluation of sports load is needed,it should be combined with other calculation methods of sports load.
