This study aims to investigate the effects of two different Tabata-based high-intensity interval training (HIIT) modalities on neuromuscular and physiological performance in competitive table tennis players. Participants will be randomly assigned to either a calisthenic/plyometric HIIT group or a kettlebell-based HIIT group. Both groups will perform their respective training protocols in addition to regular table tennis training for eight weeks. Physical performance and physiological variables will be assessed before and after the intervention.
