The aim of this study was to investigate effects of two different high intensity interval program for 3 weeks on body
composition and strength of combat sport athletes. Twenty-nine combat sport athletes (karate, judo, taekwondo, wrestling) (age
21.41±1.50 years) voluntarily participated in this study. Participants were randomly assigned to two groups; Tabata protocol
and running based high intensity interval protocol. Both methods were applied to participants 3 days per week for 3 weeks.
Body composition, leg strength, back strength and hand grip strength of the participants were measured before and after the
application. Paired Sample T Test was used to determine intragroup changes while Independent Sample t-test as used to
determine intergroup changes. There was no significant difference between groups during the first measurement (p>0.05). No
significant change was found in the variables between two measurements. When groups were compared, there was difference
in back strength in favour of Tabata group.
