The facts about caffeine and athletic performance Nancy Clark, M. Questions arise about caffeine: Should I use caffeinated gels during long runs? How much caffeine is in Red Bull?
Email Summary This research tested the effects of Red Bull, an energy drink, on the performance of women athletes.
Participating in this study were 15 female soccer players, about 20 years of age. They were asked to drink either ml equal to one serving of Red Bull or a placebo drink, an hour before their daily exercise.
During this period, their heart rates, ratings of perceived exertion RPE and sprint times were recorded. There was no significant effect on any of these variables, indicating that a single serving of Red Bull gave no benefits in sprint-based exercise in women athletes.
Introduction Caffeine is known to reduce fatigue and increase attention and alertness. It is also considered to be a performance-enhancing aid. However, its beneficial effects on activities requiring high strength are unclear.
Most athletes consume caffeinated energy drinks like Red Bull, containing 80 mg of caffeine per serving. Recent studies have shown that Red Bull has a positive effect on stamina in aerobic, as well as anaerobic, exercises like bench pressing or cycling.
Although the effects of high doses of pure caffeine have been tested, lower doses as in Red Bull need more investigation. In this study, the researchers hypothesized that Red Bull consumption will improve the sprint performance in women athletes.
All the participants had been soccer players for 12 to 15 years and were currently involved in an intense exercise routine of 12 hours per week.
The participants were asked to report if they felt any side effects after consuming the drinks. Their sprint time, heart rates and levels of fatigue were recorded during the exercise.
However, no difference was observed between consumers of the placebo drinks or Red Bull. A better performance did not seem to be related to the consumption of either of the two drinks. The remaining five participants showed no difference in performance with or without Red Bull.
The heart rates of the fastest women in the Red Bull group were higher than the heart rates of the fastest women in the placebo group. Another limitation of this study is that it only tested a very low dose of caffeine available from one serving of Red Bull.
In addition, the number of sprints performed in this study is not sufficient for testing the performance enhancing effects of Red Bull.
The authors suggest future studies on the effects of higher doses of Red Bull on the performance of athletes in diverse sports involving high intensity exercises.
Conclusions The intake of one serving of Red Bull an hour before exercise was found to have no effect on the performance of trained women sprinters. No significant difference in fatigue, tiredness and heart rate was noticed between the Red Bull and the placebo drinkers.
These results are contradictory to those obtained from other studies. This may have resulted due to differences in the designs of these studies. While caffeine in small amounts may not have performance-enhancing effects on women athletes, higher doses of caffeine may increase stamina and reduce fatigue.
In addition, small amounts of caffeine in energy drinks may be effective in lower-intensity workouts.Athletes. Products. Golf Alexis Thompson.

Fifteen collegiate soccer players participated, with mean age, height, and body mass equal to ± year, ± cm, and ± kg, respectively.
To investigate the effects of a caffeine-containing energy drink on soccer performance during a simulated game. A second purpose was to assess the post-exercise urine caffeine concentration derived from the energy drink intake.
A caffeine-containing energy drink in a dose equivalent to 3 mg/kg. The effects of Red Bull Energy Drink, which includes taurine, glucuronolactone, and caffeine amongst the ingredients, were examined over 3 studies in a total of 36 volunteers.
Assessments included psychomotor performance (reaction time, concentration, memory), subjective alertness and physical endurance.
