摘要:
Long-term implementation of preventive training programs (PTP) in youth sport requires coach involvement. However, the optimal training of coaches to effectively implement a PTP remains unknown. It is also unknown if the benefits of PTP can be enhanced with multiple sport seasons of exposure. Objectives: To evaluate the influence of prior PTP exposure on movement technique in youth soccer players after completing a coach-led PTP. Design: Cluster-randomized controlled trial. Methods: Twelve youth soccer teams (n=89: age range 8-14 years)were divided into groups with (Experience (EXP);6 teams [n=18 females, n=25 males]) and without (Novice (NOV);6 teams In 30 females, n= 16 males]) previous professional-led PTP experience. The coaches and players of the EXP teams were exposed to an eight-week professional-led PTP before the coach-led PTP. EXP and NOV coaches attended the educational workshop prior to implementing the coach-led PTP. The Landing Error Scoring System (LESS) was used to evaluate movement technique. Results: Both groups improved LESS scores over time (mean difference +/- SD [post-pre] = -0.8 +/- 0.2, 95%Cl 1-1.2, 0.41, p=0.0001). Of the 64 participants classified as high risk for injury (LESS >= 5) prior to FTP implementation, a greater proportion of EXP (n = 14) compared to NOV (n = 7) participants changed risk classification from high to low (LISS Delta >= 1 and LESS <5;p = 0.03). Conclusions: Our PTP enhanced movement technique regardless of PTP experience, but the benefits of the PTP impacted a proportionally greater number of players with previous PTP experience supporting continued PTP implementation. Coaches effectively implemented an exercise-based PTP after attending a training workshop regardless of previous PTP experience. (C) 2017 Sports Medicine Australia. Published by Elsevier Ltd.
