Change of the differentiation accuracy of spatial and power parameters of movements of young 13-15 year-old football players under the influence of fatigue

The article shows the features of the changes of distinctive sensitivity of spatial movements and muscle efforts when performing movements by 13-15 year-old football players under the influence of increasing fatigue in the process of performing a training load of a game orientation. The need to study this issue is justified by experts in connection with great promising opportunities of this data to improve the training and competitive activity of football players. The determination of the ability to differentiate parameters of spatial movements under the influence of increasing fatigue has been conducted using a pedagogical assessment test by a young football player to estimate a ball flight distance after the team-mate kicks of the ball for a short (15-20 m), an average (25-30 m) and a long distance (35-40 m). The determination of the ability to differentiate given parameters of muscle efforts under the influence of increasing fatigue has been made with the help of a pedagogical test, which involved instep kick of the ball into the target at a distance of 15 m, 30 m и 45 m from the start line in the 10 m corridor wide...
