The effects of ten weekly plyometric training of judokas on anaerobic power and balance

This study was conducted to determine the effects of ten weekly plyometric training on anaerobic power in judokas. 30 male judokas participated in the study and the subjects were divided into two groups as an experimental (15 male age = 21,40 ± 1,99) and control (15 male age = 21,53 ± 1,80) groups. Judo training programme was applied in both groups for 3 days / 90 minutes per week. Experimental and control group were made warm up exercises for 20 minutes. Both groups continued with the special preparatory period judo training program. After warm up exercises, experimental group judokas were made plyometric training consisting of 15 different movements for 20 minutes loading intensity between 80% and 100%. Then they were allowed to continue the judo training. As the groups showed normal distribution, Paired Samples T-Test was applied for the significance between pre-test and post-test measurements of the groups. Independent Samples T-Test was used to analyze the difference between the test group and control group. The Independent Samples T-Test was used to analyze the difference between the experimental group and the control group. As a result of the plyometric training, when the pre-test and post-test differences of the physical measurement parameters for the experimental and control groups were compared, the mean values of back strength, anaerobic power and body fat percentage were found to be significant(p<0.05). However, there was no significance in the mean values of right hand grip strength, left hand grip strength, leg strength and flexibility(p>0.05). When the pre-test and post-test differences of the statistical balance measurement parameters were compared for the experimental and control groups, and a significant difference was found in the left anterior posterior value (p <0.05).There was no significant difference difference between mean values of right overal stability, anterior posterior right, medial lateral right, overal stability left and medial lateral left (p> 0.05). As a result, it is seen that the regular plyometric exercises increase the performance of anaerobic power and balance of judokas. It can be said that putting plyometric training besides judo training has a positive effect for performance. Keywords: Judo, plyometric training, anaerobic power , balance
