Effects of Judo Sport-Specific Training on Muscles Power in Youth Judo Female Athlete

Abstract

The purpose of this quasi-experimental study was to examine the effects of judo sport-specific exercise on muscle power in a young female judo athlete after weeks 4 and 8. The 15 female judo athletes, aged between 15 and 19, who registered as athletes in Sisaket Province provided the sample size for using simple random sampling to estimate the mean population once the population size was known. The experimental instrument was a judo sport-specific exercise performed three days per week for eight weeks. In the 1-2 week training, the heart rate while exercising was 60–70 percent of the maximum heart rate, and the perceived physical exertion score was 6-11. In weeks 3–4, the heart rate during exercise increased to 70–80 percent of the maximum heart rate, and the perceived physical exertion score was 12–16. In the next 5-8 weeks, the heart rate while exercising increased to 80–90% of the maximum heart rate, and the perceived physical exertion score was 12–16 as determined by an Index of Consistency--IOC of 1.00. The tools used for data collection were standard tools: the overhead medicine ball throw and the single jump test. Percentage, mean, and standard deviation were descriptive statistics. Inferential statistics, including one-way analysis of variance with repeated measures and comparing the pairwise differences by the method of Tukey Statistical significance was set at 0.05. The average resting heart rate was 72.60 beats per minute, and during exercise, it was 169.95 beats per minute. The mean rating of perceived exertion was 14.60. The results of a one-way analysis of the variance of the change in muscle power pre-training, after the 4th week, and after the 8th week showed statistically significant differences.
