Objective: This study aims to assess the effects of a 6-week training program that combines stretching and strength exercises on the performance of novice football players aged 15 to 18.
Methods: A double-blind randomized controlled trial was conducted with 46 participants divided into four groups: A) DHIRT (n=12), B) Static Stretching (n=13), AB) Combined DHIRT + Stretching (n=11), and C) Control (n=10). Performance outcomes included vertical and horizontal jump (VJ and HJ) distance, running speed (RS), acceleration (ACC), endurance (VO₂ max), shooting speed (SS), and heart rate (HR). Repeated measures ANOVA and post-hoc analyses were used to assess group differences and time effects.
Results: Repeated measures ANOVA showed a significant effect of time (η² = 0.827) and a significant time-by-group interaction (η² = 0.418), indicating large intervention effects. Pairwise comparisons revealed that the combined training group (AB) demonstrated statistically significant improvements over the control group (C) in HJ (p = 0.003), RS (p = 0.003), VO₂ max (p = 0.000), endurance (p = 0.000), SS (p = 0.018), and ACC (p = 0.000). VJ improved by 2.97%, HJ by 6.85%, and VO₂ max by 5.83% in the combined group. No significant changes were observed in heart rate between groups (p > 0.05).
Discussion: Combining DHIRT and static stretching is more effective than either intervention alone for improving football-related physical attributes in novice players.
