Summary

This randomized single-blind crossover trial investigated the acute effects of three different exercise modalities, namely self-myofascial release with a foam roller, dynamic stretching, and static stretching, on posture, flexibility, dynamic balance, and lower-extremity performance in adolescent karate athletes (12-18 years). Participants attended four weekly sessions at the same time of day and after a 48-hour rest period. In the first week a baseline (control) measurement was performed, and in the following three weeks each participant received the three interventions in a randomized order. Outcomes included a four-view smartphone-based posture analysis (PostureScreen Mobile), the Sit-and-Reach Test, the Y Balance Test, the 30-second Sit-to-Stand Test, and the Vertical Jump Test (My Jump Lab 2). The aim was to identify which warm-up modality offers the greatest acute benefit before karate-specific performance

Interventions

BEHAVIORAL

Static Stretching

Single-session static stretching protocol for the lower-extremity (knee flexors, knee extensors, hip extensors): 30-second hold x 5 repetitions x 15-second rest, performed under physiotherapist supervision.

BEHAVIORAL

Dynamic Stretching

Single-session dynamic stretching protocol targeting the hip flexors/extensors and knee flexors/extensors with continuous walking-based movements; 30 seconds x 5 sets per exercise with 15-second rest, performed under physiotherapist supervision.

BEHAVIORAL

Self Myofascial Release

Self-myofascial release applied with a medium-density EVA foam roller. Each lower-extremity muscle group received 5 sets of 30-second rolling at 40-60 bpm, with 4-second forward-and-back rolling cycles, performed under physiotherapist supervision
