description | OBJECTIVES: To determine the effect of energy drink consumption before exercise on indices of physical performance in untrained females. METHODS: This single blind placebo controlled experimental study was carried out at the Physiology Department, University of Dammam, Dammam, Kingdom of Saudi Arabia from September 2011 to May 2012, on 32 healthy female students, in a crossover design. They were given either a standardized energy drink or the placebo 45 minutes before the exercise. Time to exhaustion and the stages of Bruce protocol achieved were noted. Heart rate, blood pressure, peripheral capillary oxygen saturation, and blood lactate were recorded before and after the exercise. Maximum oxygen consumption (VO(2)max) was calculated by formula. Paired sample t-test was used for statistics. RESULTS: The mean age was 19.93±0.8 years, mean height 156.40±3.83 cm, and the mean weight 51.73±3.65 kg. Time to exhaustion in the placebo group was 11.67±1.51 minutes and 11.41±1.56 in the energy drink group (p<0.157). The VO(2)max in the placebo group was 34.06±6.62, while it was 32.89±6.83 in the energy drink group (p<0.154). There were no significant differences between the placebo and the energy drinks groups in regards to heart rate, blood pressure, and blood lactate levels, before or after the exercise. However, there were significant differences before, immediately, and 30 minutes post exercise for all parameters between each group. CONCLUSION: The effects of energy drinks intake on physical performance during the exercise in our small sample does not significantly differ from placebo. |
