HIIT Effects on Table Tennis Players

This study is designed as a randomized parallel-group interventional trial to examine the effects of two different Tabata-based high-intensity interval training (HIIT) modalities on neuromuscular and physiological parameters in competitive table tennis players. Twenty-four male athletes aged between 18 and 24 years will be randomly assigned to one of two groups: a calisthenic/plyometric HIIT group or a kettlebell-based HIIT group. Both groups will continue their regular table tennis training and additionally perform their assigned HIIT protocol three times per week for a total duration of eight weeks. The calisthenic/plyometric HIIT program consists of bodyweight and plyometric exercises performed in a Tabata format, while the kettlebell HIIT program consists of resistance-based exercises using kettlebells performed in the same interval structure. Each training session lasts approximately 20-30 minutes. Outcome measures will be assessed before and after the intervention period and will include agility, flexibility, vertical jump performance, sprint performance, peak and average power output, and maximal oxygen uptake (VO₂max).
