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.
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).
Karabuk University is the lead sponsor of 126 studies on the registry; 30 are open to participants now.

Behavioral: Calisthenic/Plyometric HIIT · Behavioral: Kettlebell HIIT
Participants in this group perform a Tabata-based high-intensity interval training program focused on kettlebell exercises, in addition to their regular table tennis training. Sessions are conducted three times per week for eight weeks.
Behavioral: Calisthenic/Plyometric HIIT · Behavioral: Kettlebell HIIT
Participants perform a high-intensity Tabata protocol focusing on calisthenic and plyometric exercises designed to improve agility, flexibility, vertical jump performance, and neuromuscular function. Each session lasts 20-30 minutes, three times per week for eight weeks, in addition to regular table tennis training.
Also known as: Tabata-style Calisthenic HIIT
Participants perform a high-intensity Tabata protocol focusing on kettlebell exercises designed to improve sprint performance, VO₂max, and overall physiological adaptations. Each session lasts 20-30 minutes, three times per week for eight weeks, in addition to regular table tennis training.
Also known as: Tabata-style Kettlebell HIIT
Agility Performance (seconds)
Agility will be assessed using a standardized T-test protocol to measure change-of-direction speed.
Time frame: Pre-intervention and post-intervention (8 weeks)
Flexibility (cm)
A sitting and reaching test will be used to assess lower body flexibility.
Time frame: Pre-intervention and post-intervention (8 weeks)
Vertical Jump Height (cm)
Vertical jump performance will be measured using a countermovement jump test performed on a jump mat.
Time frame: Pre-intervention and post-intervention (8 weeks)
Sprint Performance - 10 m (seconds)
Sprint performance will be assessed over a distance of 10 meters using electronic timing gates.
Time frame: Pre-intervention and post-intervention (8 weeks)
Peak Power Output (Watts)
Peak power output will be measured using a standardized lower-body power assessment.
Time frame: Pre-intervention and post-intervention (8 weeks)
Maximal Oxygen Uptake (VO₂max) (ml/kg/min)
Maximal oxygen uptake (VO₂max) will be assessed using a graded exercise test performed on a treadmill or cycle ergometer.
Time frame: Pre-intervention and post-intervention (8 weeks)
