The Effect of Plyometric, Strength and Complex Training on Agility of Young Free Style Wrestlers in Ilam City

The aim of the present study was to investigate the effect of 8 weeks of plyometric، strength and complex (plyometric-strength) training on the agility of young free style wrestler in Ilam city. This study was semi-experiment and its statistical population consisted of 328young free style wrestler of Ilam city. For this purpose، 40 subjects were randomly selected and divided into four groups (each group 10 subjects) of strength، plyometric، complex and control after Illinois agility test as their pretest. Then they performed training protocols for 8 weeks and again Illinois agility test was administered as the posttest. For data analysis، dependent t test، one-way analysis of variance and post hoc LSD test were used at PP<0. 05). Considering the differences among the groups، the results of one-way variance analysis showed no significant difference in agility among the groups in the pretest (f=856، P=0. 655) while after 8 weeks of training interventions، there was a significant difference (f=4. 48، P=0. 009). The results of post hoc LSD test showed that complex training، then plyometric and finally strength training had the highest effects on agility improvement. Of course، this difference was not significant between complex and plyometric groups and also between strength and control groups. It can be concluded that to improve the agility of wrestlers، plyometric training، particularly complex training (plyometric-strength) is more useful than only strength training. So this kind of training with an emphasis on research subjects'' characters and their input and output indexes is suggested.
