THE EFFECT OF TRAINING USING RUBBER MEDIA AND LEG DUMBBELLS TO IMPROVE UCHI-MATA ABILITY IN JUDO ATHLETES

This study aims to determine the effect of training using rubber and leg dumbbells on improving
uchi-mata technique skills in beginner judo athletes. The research method used is a quantitative method
with a one-group pretest–posttest design. The population and sample of the study were 10 judo athletes at
the Al-Jabbar Dojo, Tuban Regency, selected using a saturated sampling technique. The research
instrument used a 1-minute uchi-mata throwing technique ability test before and after treatment. The
training program was given for 16 meetings with a frequency of 4 training sessions per week using rubber
and leg dumbbells as training aids. Data analysis used the Shapiro-Wilk normality test and paired sample
t-test with the help of SPSS version 23 software. The results showed an increase in uchi-mata technique
skills after being given training treatment. The average score of athletes' abilities increased from 24 in the
pretest to 36 in the posttest. The results of the hypothesis test showed a significance value of 0.000 (<0.05),
which means there is a significant effect of training using rubber and leg dumbbells on improving uchi
mata technique skills. Based on the research results, it can be concluded that training using rubber and leg
dumbbells is effective in improving leg muscle strength, balance, and motor coordination, which supports
the uchi-mata technique in beginner judo athletes. This training method can be recommended as an
alternative for coaches to improve the throwing technique of beginner athletes.
