Predator Caffeine Boosts Testosterone and Increases Sprint Performances
It’s no secret that caffeine helps to keep you awake and alert, which is great for when you’re feeling a little tired or in need of a pick-me-up at work. However, research undertaken in New Zealand has set out to try and prove that caffeine-rich products such as coffee can do much more than just keep you awake for longer. The study wanted to see if a pre-workout drink of something rich in caffeine would help as much as using supplements from Predator Nutrition.
The researchers asked a group of nine male cyclists to drink a caffeine-based beverage before doing four sets of five 30-second sprints. They were given either caffeine or a placebo in order to compare how they performed using one or the other after the second set of each session. To see whether they had any effect, they took cortisol and testosterone samples via saliva testing after every set.
It was no surprise to some involved in the study that those given gum laced with caffeine instead of the placebo saw their fatigue levels drop by far less than those given the placebo-based gum. The cyclists who were given the placebo saw their power levels drop by 5.8%, while the cyclists given caffeine saw a far less dramatic drop of just 0.4%. These statistics are sure to generate lively discussion on the Predator Nutrition Forum.
The results of this study prove that caffeine does have a positive effect on sprint performances, as well as boosting testosterone. The testosterone levels of the cyclists given caffeine rose by between 12-14% more than those given a placebo, which shows that, by having a drink of black coffee or something with similar caffeine content pre or mid-workout, you’ll be able to perform better.
