In recent years, the use of energy drinks and preworkout supplements have increased in athletes and fitness enthusiasts across the globe. According to recent findings from the Department of Biomolecular and Sports Sciences at Coventry University in the United Kingdom, these drinks are indeed beneficial to athletes and their workouts. Their findings suggest that caffeinated energy drinks improve the results of a work out over time in trained male athletes.
In this study, the four researchers set out to determine the effects of drinking an energy drink before a workout, in particular studying the caffeinated beverage’s effects on repetitions to failure, repetitions of perceived exertion and the readiness and willingness of the trained male athlete to exert both physical and mental effort during the workout. To perform this study, 13 trained male athletes volunteered to participate. Randomly, each athlete was given either a caffeinated beverage or a placebo solution and then asked to perform a variety of exercises, including bench presses, deadlifts, prone rows and back squat exercises. The beverages were ingested about an hour before the exercises were performed.
Once the results were analyzed, the team of researchers found a variety of interesting results related to the effectiveness of taking a caffeinated energy drink before a workout. For instance, repetitions to failure increased significantly for those who had taken the caffeinated beverage, as opposed to the placebo supplement; however, repetitions of perceived exertion were higher in those who had taken the placebo supplement than those who had drank the caffeinated beverage. The biggest finding was that the readiness and willingness of the trained male athlete to exert both physical and mental effort during the workout was significantly higher in those who had taken the caffeinated beverage than those who had simply drank the placebo supplement.
This study, published in November 2011, presents trained male athletes with an interesting finding. Given the results of the experiment, one can conclude that drinking an energy drink about an hour before a workout will increase your effectiveness in the exercise as well as your mental ability to complete the exercise. Those who have consumed a pre-workout supplement are not just imagining that they are more interested, willing and able to complete the exercise regime at hand, they actually are more willing and capable of completing the routine. Of course, all athletes in training should consult with a professional before making significant changes to their diet and exercise routine, and also, athletes should keep in mind that the study finds that drinking a regulated amount of caffeine will help — not guzzling down gallons of energy drinks.
