Comparison of the results in the experimental group before and after the experiment (Note: * indicates that the difference is statistically significant).
The experimental group demonstrated significant improvements in various performance metrics after the experiment. Specifically, there was a substantial 1.6% improvement (P = 0.000 < 0.05) in the 10-meter running performance. The 30-meter run performance showed a 1.95% improvement (P = 0.000 < 0.05), and the Illinois run performance increased by 6.38% (P = 0.000 < 0.05). Additionally, the experimental group exhibited a 5.29% improvement (P = 0.000 < 0.05) in the 5x25m shuttle running performance and a 4.73% improvement (P = 0.000 < 0.05) in throwing performance. Notably, the kicking performance of the experimental group significantly increased by 49.73% (P = 0.000 < 0.05) as a result of the trial.
