The effects of fatigue on instep kick performance in soccer

Abstract

This study was applied to investigate the effects of fatigue on instep kick performance in soccer. Seven male soccer players participated in this research. Each had a minimum 6 years of soccer playing experience. The age was (mean±SD) 22.85 ± 1.57 years, height 178.14 ± 3.08 cm, weight 69.35 ± 3.71 kg, body mass index 21.86 ± 1.25 kg/m2 and maxVO2 values were 59.14 ± 4.77 ml/kg/min of subjects. The high intensity endurance protocol selected to be used in the present study has been previously applied to simulate soccer field conditions to occur fatigue on subjects. The subjects performed 5 instep kicks from the 16 m distance to the goal targets prior to, in the middle and after the implementation of a 90 min intermittent exercise protocol. Analysis of the sprint times taking a part in an exercise protocol, the significant difference was found (P
