Research the effects of plyometrics studies which are applied to professional footballers on phisical and physiogical parameters

This research was done by applying to the footballers of Bozüyük football team,which is in minör league, red group in Turkey during 8 weeks,twice each week in order to search the effects of the footballers vertical bounces (jumps) on some physical and physiological parameteres. Plyometric training program which was developed to determine the effect of plyometric training on vertical jump of soccer players and some physical and physiological parameters was applied to Bozüyükspor Football Team, which play in the sixth group of third football league, two times in each week during 8 weeks. In this study pre and post-testing experimental approach with control group was used. Test group was formed from n=24 Footballers , the percentage of subcutaneous fat thickness, the of back and leg, left and right hand grab strength, elasticity and the speed for 30 m.run were tested. To determine the differences in the improvements, arithmetic means and standard deviations were calculated. The difference between arithmetic means was calculated by using Paired-Samples T Test test . At the end of this study ; considerable increases were observed on some parameters of soccer players by means of the used training programme. In experimental group, considerable increases were observed on (P<0.05) vertical jump, the speed for 30m run (P<0.05). In control group considerable increases were observed only on leg strength.However,slight differences were observed on vertical jump ,the percentage of body fat , the of back and leg ,elasticity. It wasn't found meaningful statitistically.
