المحددات البدنية للتفوق عند لاعبي كرة القدم فئة أقل من 20 سنة

Abstract EN

The aim of this study is to identify the most physical elements that create the difference in the level of performance between football players of the U20 category.

Thus , we applied a number of physical tests (speed 10m,30m,speed endurance 10×30m (RSA), aerobic aptitude with 20m shuttle run), on a sample of 10 elite players from the first professional Algerian league (League 1)(age 19.4±0,24years old ; height 1,74±0,04 m, weight 66,67±4,51 kg) and 10 non elite players , from the second professional league (League 2)( (age 19.21±0,11 years old, height 1,76±0,04 m , weight 68,84±4,83 kg) .The results show that the elite players are faster on short distances in sprint 10m and 30m , with noticeable statistical outcomes between the two groups in test result with p<0.01 and p<0.001 consecutively according to the RSA all in favor of elite players, whereas we have not noticed any statistical difference with other indicators.

Thus, we deduce that the speed on a 10m and 30m track; in addition to endurance speed or RSA, are the main physical factors that indicate more the difference between U20 football players with different levels of play.

Consequently, we ought to focus on them during training, while absence of the difference between the two groups in our study as far as the aerobic aptitude is concerned, can be because of the lack of concern of this element in our case study’s training program.
