Effects of Integrated Neuromuscular Training on Speed and Power in Male High School Soccer Players in Shandong, China

Abstract

This study examined the effects of integrative neuromuscular training (INT) on sprint speed and explosive power in high school male soccer players. A total of 20 participants were randomly assigned to either the experimental group (EG, n=10), which received an INT program, or the control group (CG, n=10), which followed regular physical fitness training. Pre- and post-intervention assessments included the 20-meter sprint and standing long jump tests. Generalized Estimating Equations (GEE) were used to analyze group-by-time interactions. Results showed that both groups significantly improved their sprint speed over time (EG: p=0.047; CG: p=0.042), with no significant differences in explosive power between groups (p>0.05). These findings suggest that while INT may enhance sprint performance, its short-term effect on explosive power appears limited. Further research with larger sample sizes and longer intervention periods is recommended.
