أثر تمرينات البلايومترك على الأداء المهاري و بعض المتغيرات الفسيولوجية لدى لاعبي التايكوندو

Abstract EN

This study aims at identifying the effects of using plyometric exercises on the development of skill performance and the improvement of some physiological variables of taekwondo players besides determining the differences that occurred between the two groups.

The experimental group (plyometric exercise) and the control group (normal exercise) in term of the extent of development of skill performance and the improvement of some plyometric variables, the sample of the study consists of 26 of taekwondo players who got the black belt 1 Dan, they were divided into two groups.

The experimental and the control group, the experimental group has been experienced the plyometric exercise while the control group has been experienced the normal one, in order to collect data needed for this study, the researcher used the following variables in measuring the Before / After skill performance the experimental group (turn kick 3.6(0.35%), rize kick 4.0(0.63%).

back kick 3.48(0.57%), and back turn 3.15(0.42%) the control group (turn kick 1.2(0.13%), rize kick 1.6(0.27%), back kick 1.15(0.15%) and back turn 1.46(0.18%)) whereas measuring the physiological variables needs the experimental group (weight-4.05(0.2%), pulse.

Rest time -1.46(0.2%) and vital capacity 0.006(0.006%) the control group (weight-2(0.03%), pulse.

Rest time -0.7(0.09%) and vital capacity 0.003(0.003%).

The results of the study showed that using plyometric exercises has differences with statistical significance on skill performance variables of the After/ Before measuring of the two groups, so that the averages showed the notable excellence of the experimental group comparing with the control group .the results as well as indicated that there are some differences with statistical significance among the following variables of the after/ before measuring of the physiological variables on the after measuring of both groups, again the averages showed the excellence of the experimental group, based on the above results, the researcher recommends the plyometric exercise as a way to improve and develop the skill and physiological characteristics of taekwondo players.
