Article Review: The effectiveness of two Energy Drinks on Selected Indices of Maximal Cardiorespiratory Fitness and Blood Lactate Levels in Male Athletes

This study aims to study the effectiveness of energy drinks which are commonly used by athletes to boost their energy levels. These drinks are touted to reenergize their users replenishing the energy consumed during physical activities and enable them perform at a higher level. There are other benefits mentioned in this study which include mental alertness, improved performance, and stimulation of the body. This study was conducted in Iran where very few studies on the effectiveness of energy drinks had been conducted. Participants were selected from those who had filled questionnaires and were required to meet certain conditions which would ensure the results obtained were not affected. The participants were subjected to a couple of aerobic and anaerobic exercises. The participants were supposed to be physically active and had no issues with the energy drinks that were being tested. They were also expected to undertake a treadmill exercise whose speed was varied after every four days (Nader, Gaeini, and Fahimeh, 128).

In addition, these participants were fed the same diet during the day of the exercise and were not supposed to consume alcohol, and other stimulant. The study found that there was significant difference between the results obtained when a participant consumed a placebo and when they consumed Red Bull and Hype. This clearly indicates that these energy drinks affect the performance of an athlete by improving their body resilience leading to better performances. The drinks are effective because of the stimulants that they contain that are credited with the improved performance due to their stimulating effect. Consequently, the study found that Red Bull and Hype drink drinks improved the performance by 10.5% and 9.7% through by increasing time that an athlete could exercise. This improvement is closely associated with carbohydrates that are contained in the energy drinks. Caffeine on the other hand contributes to improvement of this time due to its ability to increase lipolysis from body’s adipose tissues. This processes results in oxidation of fats leading to access to stored oxygen during exercises. This allows the body to withstand more physical exercise by supplying it with that extra energy that contributes to more stamina. However, the study found that there was no increase in heart rate after consumption of the energy drinks. This observation was attributed to presence of taurine which negated the effect of caffeine. There was also a significant change in blood lactate levels after the treadmill exercise. Furthermore, there was a significant increase in the blood lactate levels as the intensity of the exercise changed (Nader, Gaeini, and Fahimeh, 128).

Study analysis

The study aimed at determining the effect energy drinks had on the users. This meant that the user had to be observed for a period of time to monitor the lifestyle of the participant and control them. This was done to satisfactory levels because the participants were not allowed to consume alcohol a day to the exercises and also were given the same meal and quantity to ensure they were all having similar body conditions. This was an important approach because it ensured that other individual body conditions notwithstanding, the participants would all have consumed similar food. The results obtained were consistent and indicated that there was an effect arising from the energy drinks. The use of placebos was also important because it duped the participants into believing they had consumed an energy drink. Therefore, their dedication to the exercise did not drop because they just thought it was a different energy drink which may not be effective like the others under study. Consequently, the results obtained indicated substantial differences which are acceptable. In addition, the statistical analysis approach used was justified and reveled the expected differences in the findings.

Strengths and weakness

The research had the right participants because it used athletic college students were likely to be highly active. This is a necessary requirement in this kind of experiment because you cannot use any subject to determine the effects of energy drinks on athletes. On top of that, the participants were observed to make sure they did not consume substances that could affect the outcome of the tests. This is very important especially when dealing with college athlete students because they are likely to use different drugs that can have an impact on the effectiveness of energy drinks. In addition, the participants were subjected to similar exercises and the time they took to get exhausted noted. This was a strength of the study because it acknowledged the difference in physical abilities of different participants which implies that they recorded different times when they engaged on the different exercises used in the study. 

The main weakness of this study is that it did not observe the lifestyle of the participants during the entire period. This implies that it cannot be determined whether the participants used other drugs that could have affected the outcome of the study. This is an important consideration due to the effect other stimulants ingested during the study period could have had on the effects of the energy drinks. On the other hand, the diet of the participants is also an important element to observe closely because food consumed contributes to long term abilities of the consumer. Therefore, this should also have been observed during the entire study period.

The only thing I could have changed in this study is to control the lifestyle of the participants during the entire period to ensure that they did not engage in activities that could affect the outcome of the study. This could have ensured that the results obtained were not affected by the lifestyle of the participants. This is important because the food consumed over the course of the study is likely to affect the outcome of the study.
