Weighted vs Unweighted Plyometric Conditioning on Vertical Jump Performance in Young Male Soccer Players

Explosive lower-limb power is essential for soccer performance and contributes to jumping, sprinting, and rapid changes of direction. Plyometric exercises are commonly used during warm-up to improve neuromuscular readiness and may enhance subsequent athletic performance through post-activation performance enhancement (PAPE). However, it remains unclear whether adding external load during plyometric conditioning provides greater benefits than performing the same exercises without additional load. The purpose of this study is to compare the acute effects of weighted and unweighted plyometric conditioning on vertical jump performance in young male soccer players. Participants complete two experimental sessions separated by 48 hours. In one session, they perform a standardized single-leg plyometric protocol without external load, and in the other session they perform the same protocol while wearing a weighted vest equivalent to 10% of their body mass. Vertical jump height is assessed before exercise and at several time points after the conditioning activity to examine the time course of performance changes. The findings of this study are expected to improve understanding of the optimal use of weighted plyometric conditioning during warm-up and provide practical guidance for coaches and sports practitioners seeking to maximize explosive performance before training and competition.

Comparative Effects of Kinesio and Dynamic Taping on Ankle Performance in Basketball Players

This study aims to compare the effects of two different ankle taping methods-kinesio taping and dynamic taping-on balance, vertical jump performance, and reaction time in basketball players. Basketball involves frequent jumping, rapid changes in direction, and single-leg balance tasks that place substantial demands on ankle stability. Reduced ankle stability may negatively affect athletic performance and increase injury risk. Taping methods are commonly used in sports settings to support the ankle joint and enhance functional performance; however, limited comparative evidence exists in basketball players. In this non-randomized, fixed-sequence crossover study, healthy male basketball players aged 18 to 30 years will receive both kinesio taping and dynamic taping applications separated by a one-week interval. Kinesio taping will be applied during the first session and dynamic taping during the second session. Each participant will serve as their own control. Performance assessments will be conducted immediately before and after each taping application. Outcome measures include dynamic balance assessed using the Y-Balance Test, vertical jump performance assessed using a mobile application-based jump test, and lower extremity visuomotor reaction time assessed using a visual stimulus-response task. All procedures are non-invasive and associated with minimal risk. The findings are expected to contribute to evidence-based taping strategies aimed at improving athletic performance and supporting ankle function in basketball players.

Stretching to Improve Jumping Performance

The study involves comparison of an 8-week plantar flexor stretching program to a shoulder stretching program for improving vertical jump performance in adolescent athletes.
