Acute effect of injury-prevention-exercise-based warm-up vs. small-sided-game-based warm-up on speed performance in young amateur soccer players

Abstract

Purpose: This study aimed to investigate the effects of an Injury-Prevention-Exercise (IPE)-based warm-up and a Small-Sided-Game (SSG)-based warm-up on subsequent speed performance in young soccer players. Method: Twelve male soccer players from the fourth division regional league in Algeria participated in the study. The participants completed both the IPE-based warm-up and the SSG-based warm-up in a counterbalanced order with a one-week interval between conditions. Linear and curved sprint performances, and change of direction (COD) speed, were assessed. Results: The results showed no significant differences between the two warm-up protocols in linear sprint performance (10m and 20m tests) or COD speed (zigzag test) (p > .05). However, in curved sprinting, the IPE-based warm-up demonstrated a significant improvement in the 8.5m curve sprint on the right side (p = .017, ES = -1.04). No significant differences were observed in the other curved sprint variables (17m on both sides and 8.5m on the left side). Conclusion: the findings suggest that the IPE-based warm-up may enhance speed performance in curved sprints. However, both warm-up protocols had similar effects on linear sprint performance and COD speed. Coaches and Strength and conditioning coaches should consider incorporating neuromuscular exercises in warm-ups to optimize curved sprint performance in young soccer players.
