About this study
Official title: Comparative Effects of High-Intensity Interval Training Modalities on Physical Performance and Physiological Responses in Competitive Table Tennis Players
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.
Read the detailed description
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).

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Calisthenic/Plyometric HIITBehavioural
Also called Tabata-style Calisthenic 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.
Kettlebell HIITBehavioural
Also called Tabata-style Kettlebell 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.

A sitting and reaching test will be used to assess lower body flexibility.
Measured: Pre-intervention and post-intervention (8 weeks)
Secondary outcomes (4)
Vertical Jump Height (cm)
Vertical jump performance will be measured using a countermovement jump test performed on a jump mat.
Measured: 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.
Measured: Pre-intervention and post-intervention (8 weeks)
Peak Power Output (Watts)
Peak power output will be measured using a standardized lower-body power assessment.
Measured: 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.
Measured: Pre-intervention and post-intervention (8 weeks)

On the ClinicalTrials.gov record for NCT07403461, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Feb 2026.
