Abstract: OBJECTIVES Penalty kick has always been the most exciting moment of the soccer game.Many cups have been won and lost with the penalties.Some players choose focusing on goal keepers movements; some however decide at the shooting point while waiting for the referees whistle.However, the most important factor is the technique of the player.A perfect technique should be executed in order to put the ball in the goal.Thus, the aim of this study was to investigate the kinetic and kinematic features of the penalty kicking technique of professional soccer players. METHODSFive professional soccer players participated in this study.Markers were placed on the thigh, knee and the ankle of the players.Each player executed 10 instep penalty kicks to the targets.Each kick was recorded on two digital cameras with 60 fps.The cameras were placed approximately 90 degree to each other.Photogrammetric analyses of the pictures were done by Pictra Software. RESULTSThe results revealed that for a successful penalty kick a perfect kinetic chain was needed.The analysis showed that players flexed their knees approximately 60 degrees and laterally rotated their ankles approximately 70 degrees and a follow through were executed by the players. DISCUSSIONIn conclusion, in order to execute a perfect penalty kick, body segments should be in a perfect coordination.Players should be aware of their body segments and use technology to analyse their techniques.
