IMPACT OF MORPHOLOGICAL CHARACTERISTICS AND MOTOR SKILLS WHEN PERFORMING GYAKU TSUKI

ABSTRACT Objective The aim of this study was to determine the influence of morphology on karate characteristics and basic motor skills for the criterion variable counter-punch (gyako zuki) in boys, after a two-year training program. Methods A system of 25 variables (12 morphological, 12 motor, and one situational (gyako zuki)) was applied in a sample of 82 karatists, aged 10 to 14 years. Data were processed using regression analysis. Results Body weight had a statistically significant influence on the criterion variable in the initial measurement, as well as on the triceps and back skinfolds in the final measurement. In the motor space, semi-squat endurance had a significant impact on both initial and final measurements. In the reduced system, triple jump, half-squat endurance, and long jump impacted the initial measurement, while the 30-second torso lift, hyperextension on the bench, and semi-squat endurance impacted the final measurement. Conclusion From the data obtained, it can be concluded that the counter-punch (gyako zuki) performance results were better in participants with higher body weight, longer arms, less subcutaneous upper arm and back fat, greater static and explosive power in the lower limbs, and greater hamstring and spine flexibility.
