Comparative Effectiveness of Active Recovery and Static Stretching During Post-Exercise Recovery in Elite Youth Basketball.

Purpose : To compare the effectiveness of active recovery (AR) versus static stretching (SS) during post-exercise recovery in basketball. Methods : Using a counterbalanced crossover design, 17 elite youth male players completed two 90-min training sessions, followed by either AR or SS. Differences in jump height (CMJ), heart rate variability (Ln-rMSSD), muscle soreness (VAS), perceived recovery (TQR) and hormonal biomarkers (cortisol, testosterone, testosterone:cortisol ratio) between interventions were assessed at pre-session, post-session (except hormonal biomarkers), post-recovery and 24 h post-session. Differences in Ln-rMSSD were additionally assessed upon awakening on training day, and the following morning. Results : No significant differences were found between interventions at corresponding time points ( p  > .05). However, the within-intervention time course of recovery differed, as CMJ values were lower at post-recovery, compared with all other time points, in SS only ( p  < .05, effect size [ES] moderate-to-very large ). Additionally, Ln-rMSSD values failed to return to baseline at post-recovery in AR only ( p  < .05, ES large-to-very large ). Similarly, TQR scores were impaired at post-session and post-recovery in AR only ( p  < .05, ES moderate-to-large ). No differences were reported for the remaining variables ( p  > .05). Conclusion : Differences between AR and SS were probably due to short-term phenomena, indicating that neither strategy was likely superior for improving recovery in the longer term. Overall, neither strategy seemed to significantly improve post-exercise recovery.
