| Objective:The Chinese Tennis Hope Project included in the National Fitness Program,Short Tennis,is an effective means and method for children aged 5-10 to learn tennis[1].7-8 years old is the first sensitive age group for children's physical development.The development of their physical fitness in this age group is critical to their ability to exercise and growth.This article studies the impact of short tennis training intervention on children's physical fitness,can better promote children's future growth and development,and enhance their athletic ability.At the same time,more children can participate in the sport,expand the tennis population,and transport more tennis balls.Many people.Methods:The paper used short tennis as an intervention.From the Chengdu Chadianzi Primary School,50 randomly selected boys?26 boys and 24 girls?were divided into experimental and control groups?25 students each,13 boys and 12 girls?.Short-term tennis training interventions were conducted after school and the control group did not participate in other sports after leaving school.The experimental group passed short-term tennis training for 1 hour three times a week for 12 weeks,learning to grasp the forward and reverse swings and starting serve techniques within 12 weeks,and able to perform a simple game after the training.Before and after the exercise intervention,subjects'grip strength,seat flexion,50m run,1m skipping,4x10m return run,single leg closed eye indicators were tested and the experimental data were recorded.SPSS was used to analyze the experimental data.And make an analysis.Results:After 12 weeks of short-term tennis exercise intervention:?1?In the control group,the results of the 50-meter race were 11.74s,the experimental group was10.96s,and the experimental group was 0.78s higher than the control group,with significant differences.?2?In the control group,the jump score was 44.12 in 1 minute,68.40 in the experimental group,and 24.28 in the experimental group,which was significantly different from the control group.?3?In the control group,the score of the 4×10 meter reentry run was 16.12 s,and that of the experimental group was 15.25 s.The results of the experimental group were 0.87 s higher than those of the control group,and there was a significant difference.?4?In the control group,the results of standing with closed eyes on one leg were 3.37 s,and the experimental group was 4.47 s.The experimental group was 1.1 s faster than the control group,with significant difference.?5?The grip strength of the control group was 2.44kg,and that of the experimental group was 3.61.The experimental group had a 1.23kg increase compared with the control group,with significant differences.?6?In the control group,the standing long jump score was 106.32cm,and the experimental group was 115.72cm.The experimental group had 9.4cm increase compared with the control group,with significant difference.?7?In the control group,the anteversion of the sitting position was 9.47 cm,and that of the experimental group was 10.42 cm.The experimental group was 0.95 cm higher than the control group,but there was no significant difference.Conclusions:?1?The 12-week short tennis ball has a significant increase in children's 50-meter speed performance,and has a higher impact on boys than girls.?2?The 12-week short tennis ball has a significant improvement in the 1-minute rope skipping of children's coordination ability and the 4×10 meter return-to-run performance of sensitive quality.?3?The 12-week short tennis has a significant increase in children's upper body strength grip strength and leg strength long-range long jump performance,and the influence of boys in standing long jump indicators is greater than girls.?4?The 12-week short tennis ball has a certain effect on the children's flexible quality of seated body flexion and balance of single-legged closed eyes,but the effect is not obvious. |
