The Effects of Resistance Training on the Strength of the Leg Muscles of Judo Athletes

Abstract

       In this thesis, the researcher studies the effects of resistance training on the strength of the leg muscles of judo athletes.

       The sample population consisted of twenty-four male judo athletes at Ramkhamhaeng University using the technique of purposive sampling. The members of the sample population were divided into two groups of twelve each. The first group was the control group (trained with a judo training program) and the second group was the experimental group (trained with a judo training program and a resistance training program. The training was conducted for eight weeks with three days each week. The strength of the leg muscles was tested prior to the training and after the training in the fourth and eighth weeks. The statistics used in data analysis were mean (M) and standard deviation (SD). The techniques of t test, one-way analysis of variance (ANOVA) with repeated measures, and Tukey B’s multiple comparison were employed.

       Findings are as follows:

1. The strength of the leg muscles prior to the training and after the training in the fourth and eighth weeks of the control group was 2.30, 2.39, and 2.54 kilograms, respectively.


2. The strength of the leg muscles prior to the training and after the training in the fourth and eighth weeks of the experimental group was 2.31, 2.44, and 2.63 kilograms, respectively.


3. The mean of the strength of the leg muscles between the control group and the experimental group after the training in the eighth week exhibited differences at the statistically significant level of .05. There were no other differences.


4. The mean of the strength of the leg muscles of the control group prior to the training and after the training in the fourth and eighth weeks exhibited no differences.


5. The mean of the strength of the leg muscles of the experimental group prior to the training and after the training in the fourth and eighth weeks exhibited differences at the statistically significant level of .05
