Essay On Effects Of Caffeine On Exercise
Effects of energy drinks caffeine on exercise
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…
They had written consent from a parent or guardian to participate in the study. 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 and keep the diet as normal as possible on test days. The placebo was just 118 mL of …show more content…
Peak power was the highest in group (CAF-3) which received 3 mg·kg–1 of caffeine and average power was highest in group (CAF-5) where the subjects received 5 mg·kg–1 of caffeine. These results can be useful for parents who want their elementary school ages boys to have an edge on the completion, and it can lead to a further study to see what the optimal amount of caffeine per mg·kg–1 that would be best for athletic performance or just all day performance in the classroom or at home. The study was beneficial to see whether or not different doses of caffeine could enhance anaerobic functions in boys aged 8 to 10. But, I did not hypothesize that a lower dose would account for higher peak power and that a high dose would be higher mean power. Caffeine is rapidly absorbed by the body and can be found inside the blood stream 5 to 15 minutes after consumption, and will spike 40 to 80 minutes after consumption and is beneficial for athletes to ingest 1 hour before they are going to engage in physical activity. Many high school and college aged students rely on energy drinks and caffeine to get them through their school day and late night study sessions. Caffeine can be used as a supplement to increase endurance and to increase muscular
