### Dynamic Analysis of Lateral Jump  
An analysis was conducted on the kinetic parameters of the lateral jumps in the pre-test and post-test, including the jump distance, the ground reaction force of the left and right foot (GRF of left and right), the vertical ground reaction force (V-GRF), the resultant ground reaction force (R-GRF), and the trajectory at the peak resultant force (T-PRF). After 12 weeks of the ASTP, the post-test results of all parameters of the experimental group were better than the pre-test results of the experimental group and the pre-test results of the control group, and the two-factor mixed variance analysis results showed that the \(F\)-values of each parameter were significantly different (\(p\) < 0.05), as shown in Table 3. Lateral jumps were detected four times, as shown in Figure 1. Each time a participant jumped, from take-off to landing and from landing to take-off, it took about 1 s. As shown in Figure 2, for list No. 7 of the participants of the experimental group, the time from the third landing of the right foot to take-off was 0.98 s (7.363 s to 8.343 s), with a total energy conversion of 4658.84 N, and angle of the T-PRF was 62.4\({}^{\circ}\). \begin{table}

Table 3: Analysis of the dynamic parameters of lateral jumps. The V-GRF on the back of the participants was lower than the R-GRF, indicating that the participants distributed force into a horizontal force. The T-PRF angle was between 60.7\({}^{\circ}\) and 68.6\({}^{\circ}\). For example, experimental group member No. 7's right foot jumped 60.7\({}^{\circ}\)
