Effects of high-intensity training on neuromuscular fatigue in early adolescent soccer players
Main Article Content
Abstract
Purpose: This study aimed to assess the extent of neuromuscular fatigue in early adolescent soccer players following a high-intensity training session that combined Speed, Agility, and Quickness (SAQ) drills with small-sided game (SSG). Method: Fourteen youth soccer players participated in the study (year: 13.21 ± 0.69 years, height: 156.28 ± 3.95 cm, weight: 47.14 ± 10.77 kg). A within-subjects, repeated-measures design was used to evaluate the variations in neuromuscular fatigue, assessments were conducted immediately before the training session, immediately after, one hour post-session, 24 hours post-session, and 48 hours post-session. The study employed the 10-meter speed test and the Countermovement jump (CMJ) test, both recognized as valid and reliable indicators of neuromuscular fatigue. Statistical analysis was performed using SPSS software. Results: The results revealed statistically significant differences in CMJ test scores between the initial measurement (pre-session) and one hour post-training (p < .05), as well as 24 hours post-training (p < .05). Conclusion: The high-intensity training session for youth soccer players induced significant neuromuscular fatigue, persisting up to 24 hours. These findings underscore the importance of monitoring neuromuscular fatigue to optimize recovery and reduce the risk of overexertion and injuries in early adolescent soccer players.
