Practical analysis of power in professional footballers

Abstract

The vertical jump measure the impulsive capacity, the main goal of this study is describing the coordination and elastic and contractile components of professional soccer players when performing the power test, through jumps, made on the Axom Jump 4.0 contact platform. It is an applicative study, since it carried out a jump test which provided inputs to define the training from the evaluated athletes must do. Sample population was 9 players who acted as midfielders average age: 22 years, size: 1,77: weight: 73kg and BMI of 23.38, power was achieved through the Abalakov, SJ and CMJ jumps. The coordination and elastic influence was determined and correlated with BMI and compared with the other national and international populations. The IMB SPPS Statistics version 24 program was considered for the statistics. The assumption of normality was verified by applying the Shapiro-Wilk test and the correlation and differences with the parametric statistics were established. The power obtained was from 848,4 in the ABK, 845,0 w in the squat jump and 844,2 w in CMJ, which represents acceptable values against an international parameter. The jump valuation is related to the IE of the muscle fibres from the lower bod, and the CB which indicates the coordinative capacity of the players, the relationship of these determine the contribution of the muscle fibres, in this type of case the 9 evaluated players present very high values of muscular work or IC.
