Caffeinated energy drinks are commonly taken to improve exercise performance, but there few studies on the influence of different doses an athlete's performance. We conducted a double-blind, randomized, counter-balanced, and crossover research study examine effects low caffeinated drink (Low ED) or high (High supplement haematological response, oxidative stress in triathletes. Twelve male participants underwent three testing sessions separated by weekly intervals, consisting sprint triathlon training (0.75 km swim, 20 cycle, 5 run). Before during trials, were randomly provided with either placebo (PLA) group, Low ED High group. Exercise performance group decreased significantly compared PLA groups (p < 0.05). However, also experienced improved = 0.054). Analysis variance revealed no differences among cortisol testosterone levels, Borg Rating Perceived Exertion score > 0.5). Furthermore, superoxide dismutase (SOD) was reduced lowest PLA, significant decrease thiobarbituric acid reactive substances (TBARS) observed This indicates that consumption may reduce athletes. individual should be considered when supplementing side effects.
