Acute caffeine consumption improves performance in many different athletes. Lara B and others (2015) demonstrated that acute consumption of a caffeinated beverage or other caffeinated substance could improve the performance of sprint swimmers. Energy drinks have become very popular in sports. Caffeine is no longer a drug, so athletes are increasingly interested in improving their performance. Today there are numerous studies demonstrating that a moderate dose of caffeine is ergogenic for swimming endurance. Say no to plagiarism.

Get an original essay This study was conducted on fourteen male swimmers between the ages of 16 and 22, who performed two tests after ingesting a caffeinated beverage. The swimmers also performed a countermovement jump, a grab test, and a maximum swim test on a swimming ergometer. One group drank an energy drink with caffeine and another group drank the same drink without caffeine. This particular group of men were light caffeine consumers, had no history of cardiopulmonary disease, and had had no injuries in the past three months. The substances were ingested 60 minutes before the start of the tests. Once the tests were completed, a blood sample was taken. It was shown that caffeine intake increased jump height and showed increased grip strength during the grip test. It also increased peak power during the swimming ergometer test. To determine how much caffeine each individual should consume, subjects were weighed 2 days before the start of the first experimental trial. Individuals were encouraged to abstain from all dietary sources of caffeine, alcohol or stimulants one week prior to running the trail. Individuals began with a standardized 45-minute warm-up, then progressed to the jump test. Two maximal countermovement jumps were performed with one minute of rest in between. The higher jump of the two was used for the analysis. Individuals then proceeded to the two-handed grip test. Two attempts were made with both hands and the highest value was used for analysis. After a short recovery period, they began swimming their best style for a 50-meter swim. Three different times were recorded for each swim and the fastest of the three was used for analysis. No other swimmers were present in the pool during the individual time trial. The last test performed was the swimming ergometer test. The swimmers started in a stationary position and were then told to swim as fast as possible against resistance. The maximum and average values ​​were taken and used for analysis. A caffeine-containing substance or placebo was administered to trained and untrained swimmers before a 2x100 relay. After ingesting caffeine, trained swimmers showed great beneficial effects. Trained swimmers reduced their time to completion by 2%. The performance of the placebo group (untrained swimmers) did not show the same beneficial effect as the trained swimmers. However, both untrained and trained swimmers showed elevated levels of blood lactate concentrations. The same test was used for a 2x200m freestyle time trial but it did not show the same effectiveness as the other time trial. Caffeine has not been shown to be effective in improving swimmers' performance. Even if the.
