Comparative biomechanical analysis of mid-height reception between professional and amateur soccer players/Análisis biomecánico comparativo de recepción a media altura entre jugadores profesionales y amateurs de fútbol

Soccer is a sport of various motor actions, where the reception of the ball is classified as a control action at different heights, speeds and angles. The player must have the ability to receive the ball in order to generate a different action: a pass, shot or dribble; its optimization implies greater probabilities of technical-tactical performance. In this sense, the objective of the research was to biomechanically analyze the mid-height reception technique in professional and amateur soccer players using video analysis as a measurement method. The research was descriptive-explanatory of correlational order, four variables of the motor movement (D: distance covered; AM: maximum acceleration; VM: maximum speed and AF: amplitude of the femorotibial joint) are analyzed through video-analysis with Kinovea . Five professional players (group 1) and 15 amateur players (group 2) were studied. The amateur soccer players presented a higher mean in all the variables studied, “D” (group 1: 72.17cm; group 2: 101.27cm; p=0.001), “AM” (group 1: 61.84m/s 2 ; group 2: 101.73m/s 2 ; p=0.000), “VM” (group 1: 8.18m/s; group 2: 12.55m/s; p=0.000) and “AF” (group 1: 62.6°; group 2 : 75.2°; p=0.002), which behaves significantly different in all cases. The biomechanical analysis carried out on professional and amateur soccer players, in the technique of receiving the ball at mid-height, concludes that amateur players require greater technical improvement, regardless of their experience in competitions.
