Determining the relative contribution of physical fitness factors in the success of Shotokan style kataro

Identifying effective factors in the performance of karate athletes to design better training programs is one of the most important goals of trainers. In this regard, the aim of the present study was to determine the relative contribution of physical fitness factors in the success of Shotokan-style kataros in Kerman. 14 Shotokan style young men, all of whom had national medals, were purposefully selected and based on an official competition (led by the researcher) and the number of medals won in the last year, they were divided into two successful groups (n=5) and Failed (n=9) were divided. Each subject participated in this research for three sessions. The first session included filling out a questionnaire, measuring body composition, measuring leg and paw strength, and trunk muscle endurance. The second session included measurement of flexibility, agility and anaerobic power tests, and the third session included measurement of balance, speed and aerobic power. To compare factors between successful and unsuccessful groups, Student's t-test was used and to determine whether group membership is possible based on physical factors or not, diagnostic regression analysis was used. The results showed that muscle endurance factor (shoulder girdle) (P<0.5), muscle endurance (abdominal) (P<0.5) and dynamic balance factor (P<0.5) between successful and Failed had a significant difference. Together, these factors defined 39% of the variance changes in group performance and correctly predicted group membership in 76% of cases. In general, the results of this research showed that upper body muscular endurance and dynamic balance are physical factors that define success in Shotokan style kataro. Therefore, emphasizing on the improvement of these physical fitness factors is recommended to coaches and athletes of this style.
