수영선수들의 체격 및 신체조성이 전신반응시간에 미치는 영향

Abstract

This research is about analyzing the motor activity reaction of elite swimmers, related to their physique and body composition and in use of this data is for collecting basic essential data for elite swimmers performance enhancing. From the measurement held from the Korea Institute of Sport Science has collected data from 5 different Regional Sports Science Center’s, middle school and high school students physical ability measure scale was used to 586 students that are elite swimmers the measure was held throughout 5 years, from 2011 to 2014. The measurements were height, weight, sitting height, thigh and measurement of circumference of chest. Swimmers reaction time was measured and body fat percentage, BMI were used for the body composition’s variable. The research results that were correlated were the weight for middle school girl students and high school boy students, for middle school boy students the physique and body composition’s variable were not correlated. In the multiple linear regression with the reaction time, middle school girl students and high school boy student’s data was shown that there is a significant correlation with the BMI and also for high school girl student’s body fat percentage was shown a significant correlation. In conclusion, high school students in both sex showed that the higher BMI and body fat percentage the lower in reaction timing, for middle school girl students when the BMI grows the reaction time got faster.
