Audiovisual Conditions During Eight Weeks of BOSU Training in Taekwondo Athletes

This nonrandomized three-group study described changes in taekwondo-specific electronic impact scores, selective attention and repeated-sprint performance over eight weeks of supplementary BOSU ball balance and proprioception training delivered under three different audiovisual conditions. Athletes were recruited from three taekwondo clubs in Malatya, Turkiye, and each club trained under one condition: high-tempo music (140-160 beats per minute) combined with projected elite competition footage (MV), low-tempo music alone (110-130 beats per minute; LTM), or no music and no video (CON). All three groups completed the same BOSU programme, three sessions per week for eight weeks (24 planned sessions of 40-45 minutes), in addition to their usual taekwondo training. Assessments were conducted at week 1, week 4 and week 8. Because allocation was not randomized and each condition was delivered predominantly within one club, audiovisual condition is confounded with club and the analyses are exploratory and descriptive rather than causal.

Effects of Myofascial Release, Dynamic and Static Stretching in Adolescent Karate Athletes

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
