Abstract
Abstract
Introduction: Reaching the peak of sports performance is the main goal of athletes and coaches. Nutrition is a very important factor in achieving this goal. The purpose of this study was to investigate the effect of caffeine consumption on the reaction and performance of soccer goalkeepers.
Materials and methods: The statistical population of the present study included Iranian football goalkeepers with at least four years of training and playing experience in Iranian football leagues, with an age range of 40-18 years. The number of participants was 12 people who were divided into 3 groups of 4 people. The groups, including the control group, the placebo group, and the caffeine group, performed the Sargent jump test using the my jump 2 application and the reaction test on the wall by touching colored lights with the reaxing train in react device. Tests were carried out 5 days apart and by moving the groups. The changes were implemented in three stages with an interval of 5 days.
Findings: One session of caffeine consumption had a significant effect on jump height, jump speed and jump time of soccer goalkeepers. This effect in the third stage was between the caffeine group and the placebo group (p<0.05). One session of caffeine consumption had no significant effect on the explosive power and jumping power of soccer goalkeepers (p<0.05). One session of caffeine consumption had no significant effect on reaction time, reaction and average reaction of football goalkeepers (p<0.05).
Discussion and conclusion: Our findings show that a dose of 0.5 mg/kg of caffeine does not have a small and significant effect on jumping performance in soccer goalkeepers.
