Abstract

Karate punching is an integral component of karate such as punch force, punch speed and punch response time. Previous research indicated punch force, punch speed and punch response time can be predicted from power, balance and agility tests in males. Research aim was to predict punch force, punch speed and punch response time based on general motor and karate specific motor fitness factors. Participants were 31 young adult female karate athletes classified as elite, intermediate andnovice by experience and belt rank. General motor ability tests were standing long jump, isometric grip strength, sit-reach flexibility, arm crank and dynamic balance. Karate specific tests were karate agility, karate flexibility, punch force, punch response time, punch speed 50cm and punch speed 100cm. Statistical analyses were descriptive statistics; correlations between reverse punch factors and general motor and karate specific variables; stepwise multiple linear regression to evaluate predictor variablesfor different punch factors; and factor analysis evaluated interrelationships between four punchperformance variables. Punch force was significantly and positively correlated with general balance, karate flexibility, long jump and strength; whereas punch response time with balance and karate flexibility; punch speed 50cm with general flexibility, karate flexibility and balance; and punch speed 100cm with general balance and inversely related. Regressions indicated punch force was predicted by balance; punch response time by balance; punch speed 50cm by general flexibility and balance; and punch speed 100cm by balance. Punch response time, punch speed 50cm and punch speed 100cm loaded on one factor and punch force was loaded on a second factor. Regression analysis indicated the most predictive variable for punch performance was dynamic balance, which has relevance to prepunch stance and punch delivery. Factor analysis indicated punch force is a different concept from punch response time and punch speed, suggesting different training types to enhance punch performance.
