| Yuan Weimin pointed out: "The road to winning the championship of the Chinese women’s volleyball team comes from every training session." The quality of training courses is the basis for the improvement and development of the skills and combat level of the entire team and athletes,and plays an irreplaceable role.As the second-tier team of women’s volleyball in China,the youth women’s volleyball team is the foundation and guarantee for the Chinese women’s volleyball team to continue to maintain the foundation and guarantee of the world’s strong team,and to improve the competitive ability and training level of the national youth women’s volleyball team.The purpose and significance of this thesis is to clarify the current characteristics of China’s young women’s volleyball training sessions and to provide a scientific basis and reference for further improving the quality of China’s young women’s volleyball team training sessions.The research uses literature,observation,testing,mathematical statistics and logical analysis to investigate the density of the training sessions,the number of touches,the number of jumps and the heart rate of the 13 young women’s volleyball teams that participated in the "2022 National Youth Volleyball Training" organised by the Volleyball Management Centre of the State General Administration of Sport of China during the training sessions.The data of the training sessions were monitored in the field,including the number of touches,the number of jumps and the heart rate.Through the analysis and research on the quality of the training sessions of our young women’s volleyball team,the following conclusions were drawn:1.The organisational density of the sessionsThe 2022 national youth women’s volleyball training sessions were divided into six modules: warm-up activities,training practice,explanation and discussion,organisation and scheduling,rest and end relaxation.The proportion of each module was 6.8%,83.3%,4.7%,0.8%,2.5% and 1.9% respectively,and the organisational density of lessons for all teams in the training set reached over 94%,with a high organisational density of lessons.By comparing with the last 2 training cycles,the coaches of each team gradually realised the importance of the organisational density of classes to enhance the training intensity of the athletes,and the characteristics of compact and high frequency training gradually became the training style of the youth team coaches.2.Practice densityThe average total time of each lesson in the 2022 national youth women’s volleyball training set was 202.8±30.6 minutes,with 169±34.9 minutes of lesson practice time and an average practice density of 82.8±5.6%,with a maximum value of 89.6% and a minimum value of 75.6%.The average practice density of individual players was 57.3%,with a maximum value of 72.8% and a minimum value of 36.6%.By comparing the practice density of the youth volleyball training sessions with that of the last 2 cycles,the increase in practice density of the youth volleyball training sessions in the new2022 cycle was not significant compared to the last 2 cycles.3.Heart rateThe average heart rate of the athletes in the 2022 national youth volleyball training sessions was 120.7 beats/min per session,with a maximum heart rate of 184 beats/min and a mean maximum heart rate of 164.82 beats/min.The overall heart rate in the fourth range(≥160beats/min)accounted for 1.4% of the total time,while the heart rate in the third range(159-140beats/min)accounted for 14.1% of the total time.14.1%,40.7% in the second interval(139-120beats/min)and 43.8% in the first interval(≤119 beats/min).Compared to the heart rate of the teaching game,there is a certain difference between the maximum heart rate of the players in the second passer and sub attacker positions and the teaching game.This reflects that the coaches have a lower proportion of training programmes for the second passer and the sub attacker in their daily training.Compared to the heart rate of the last two training sessions,the average heart rate and the duration of the high-intensity heart rate interval of the training sessions of the new 2022 youth volleyball cycle have increased significantly.4.Number of ball touchesThe average number of touches per session in the 2022 national youth women’s volleyball training sessions was 677.9,with a maximum value of 12795 and a minimum value of 383.The average number of ball touches per training session for the main attacker,secondary attacker,second passer and setter were 667.5,603.9,884.1 and 592.7 respectively.By comparing the number of touches per training session with the last 2 cycles,the average number of touches per training session in the new 2022 cycle has increased by nearly 100,reaching the highest value.5.Number of jumpsThe average number of jumps per training session for the 2022 national youth volleyball team was 170,with a maximum of 431 and a minimum of 61.The average number of jumps per training session for the main attacker,secondary attacker,second passer and setter were 174.6,177.4,158.6 and 176.4 respectively.By comparing the number of jumps in the training sessions with the last 2 cycles,the average value as well as the maximum value of the number of jumps in the training sessions of the new 2023 youth volleyball cycle have been reduced. |
