Time of reaction and time of execution in goalkeeper of football category sub-15

Abstract

Introduction and objectives: The goalkeeper’s position of football demands a good perceptive capacity, speed of reaction and of execution. The purpose of this study is to evaluate the speed of reaction and of execution for visual stimuli in goalkeeper sub-15 of two sports clubs of Santiago of Chile.
Method: 6 goalkeepers sub-15 were evaluated (14,0 ± 0,63 years of age; 60,5 ± 3,62 kg; 1,69 ± 0,06 mts). Each one received twelve launches of a ball of football realized by a located machine 25 meters of the zone of fall. Every sportsman had to intercept the ball in someone of 4 zones, measuring his speed of reaction and execution opposite to the visual stimulus.
Results: The percentages in the decision of the zone of fall of the ball were 100 % in the left, right zone and forward. The zone of behind presents a failure of 50 %. The times of reaction and of execution show significant differences between the goalkeepers (p=0,007; p=0,001 respectively). The speed of reaction for zones, they show significant differences (p=0,012).
Conclusions: The speed of reaction and of execution they are different between the goalkeepers, existing a relation between the time of execution and the weekly days of training.
