Experimental Research on the Effect of Rope Ladder Exercises on the 30-Meter Straight Sprint Speed of 11～12-Year-Old Children
Objective: To explore the effect of rope ladder exercises on the 30-meter straight sprint performance of 11～12-year-old children, and further verify their benefits and applicability to children, so as to provide a basis for the development of scientific children training plans. Method: The 11～12-year-old sprinting sprinters in Daxing Sports School were selected as experimental subjects for a 9-week (twice a week, 15 minutes each time, in physical education classes on Mondays and Wednesdays) experimental study. They were divided into the experimental group and the control group with 8 boys and 8 girls in each group, and there was no significant difference between the children in the two groups (P> 0.05). The experimental group performed rope ladder exercises in addition to daily training, the control group only completed daily training without rope ladder exercises, and the experiment collected their 30-m sprint performance data for analysis and discussion. Result: Experimental results showed that after 9-week intervention training, the experimental group had a significant difference in 30-m straight sprint performance compared with that of the control group (P< 0.05), and its performance improvement was better than that of the control group. Conclusion: The improvement of the 30-m straight sprint performance of the children in the experimental group was better than that in the control group, which showed that rope Ladder exercises had a positive effect on improving the 30-m straight sprint results of children aged 11～12.
