The influence of Red Bull energy drink on speed, power and rebound performance of female volleyball players at the performance level
HARRISOVÁ, Helena Estella
The aim of the bachelor's thesis was to find out the influence of Red Bull energy drink on the speed, strength and rebound performance of female volleyball players at the performance level. Fifteen first-league volleyball players of VK Madeta České Budějovice club from the women's category were tested. The performance of female volleyball players was assessed using a bicycle ergometer, rebound board and hand dynamometer in the middle of the 2023/2024 season at the laboratory of load diagnostics at the department of physical education, University of South Bohemia. Each player underwent testing twice with a one-week break. Participants were given a Red Bull energy drink and a placebo in random order. Drinks were blinded. Anaerobic parameters were examined together with the blood lactate concentration using Wingate test, the average height recorded by the Bosc test and the maximum hand grip strength using the hand dynamometer. We did not confirm any significant effect of Red Bull energy drink on the observed performance. The t-test and Cohen's d were used to assess the statistical and substantive significance of the results. No significant effect of Red Bull energy drink on the observed parameters was found, with the exception of the maximum strength of the right-hand grip (d=0,29), the average height of the jump with a bounce from the left leg (d=0,22), maximum heart rate (d=0,29), maximum relative power (d=0,31), fatigue index (d=0,4) and lactate (d=0,2), for which substantive significant influence was recorded with only a small effect. Based on the evidence obtained from the measurements, it was proved that the Red Bull energy drink in a short period of time (20 min) had no effect on the performance of athletes.
