This study aimed to determine if there was a significant difference in heart rate recovery (HRR) after consuming an energy drink during sport activity. Male subjects aged 17-18 participated in standardized aerobic exercises, categorized as athletically active or inactive based on V02 max measured by Beep test. Each group consumed a caffeine, sugar and taurine-containing energy drink and a placebo effect drink and performed a sport activity (rowing simulation), after which HRR was measured and the effect on the two experimental groups compared. Results showed that moderate consumption of energy drinks had no visible effect on HRR for students who are not professionally involved in sport.
