Study Objectives 
To examine the comparative effects of calisthenic/plyometric HIIT and kettlebell-based Tabata 
HIIT on physical performance and physiological responses in competitive table tennis players. 
Study Design 
Randomized, parallel-group experimental study conducted over 8 weeks. 
Participants 
 
Sample size: 24 male competitive table tennis players 
 
Age range: 18–24 years 
 
Inclusion criteria: actively training competitive athletes 
 
Exclusion criteria: musculoskeletal injury, cardiovascular or metabolic disease 
 
 

Interventions 
Group 1 – Calisthenic/Plyometric HIIT 
 
Tabata-based HIIT protocol 
 
3 sessions/week for 8 weeks 
 
Performed in addition to regular table tennis training 
Group 2 – Kettlebell HIIT 
 
Tabata-based HIIT protocol 
 
3 sessions/week for 8 weeks 
 
Performed in addition to regular table tennis training
