Abstract- Children are one of the largest groups of consumers for things like sports drinks and energy drinks. But in kids caffeine is rarely used as a supplement to enhance performance.
Introduction- The purpose of this study was to observe and determine if different doses of caffeine can enhance anaerobic functions of males aged 8 to 10 years old. I hypothesized that the larger the dose of caffeine, the higher the anaerobic performance of that boy would be. There have been many other studies on a similar topic and they were inconclusive about whether or not caffeine had a major effect on anaerobic performance or not so, another purpose was to further data to …show more content…
All 26 participants were healthy with no past medical concerns, and were active, but did not participate in any extracurricular sports. Every participant had to visit the lab five times. The first time was to fill out a questionnaires, consent forms, and to take skinfold measurements for determine body fat. They also had to do an exercise test to determine peak oxygen consumption by using the Wingate test. On visits2-5, 1 of 4 random treatment trials was used to assign groups. Group one was (PL), which means 0 mg caffeine·kg–1. 1 mg caffeine·kg–1 was group (CAF-1), 3 mg caffeine·kg–1 was group (CAF-3), and 5 mg caffeine·kg–1 was group (CAF-5). One hour before trials the subjects ingested the treatment drink to have maximum cardiovascular effect. Each subject had a 3 minute warm up on a bike. During the warmup there were 2 all out exertions of peak force for 5 seconds followed by 3 or 4 maximum voluntary contractions on a dynamometer. The Wingate test was followed by maximum grip strength tests. All trials were done in a 2 to 3 week period with at least 48 hours in between bouts. This regiment included no exercise before testing and no eating 3 to 4 hours before testing …show more content…
My hypothesis is that energy drinks will have a positive effect on exercise performance. This study is to further confirm that energy drinks are beneficial to exercise performance, and it adds to the existing data and knowledge on the topic.
Methods- Subjects include: 10 endurance athletes, 12 young trained cyclist, 17 moderately trained subjects, 15 recreationally active subjects and 6 endurance trained runners. They were all in good health and had no past issues for medical concern. A bike was used to find VO2 max.
The 10 endurance athletes used the following and then got on the bike to go 60 minutes at 70% of VO2 max. 1) A: 500 mL regular Red Bull, 2) B: 500 mL Red Bull only CHO and caffeine without taurine. 3) C: 500 mL Red Bull only CHO without caffeine or taurine ∼2.0 mg/kg). After testing it was concluded that there was an increased endurance time in A compared to B and B compared to
