The enhanced exercise performance resulted in a significantly greater increase in both growth P505-15 hormone and insulin concentrations, indicating an augmented anabolic hormone response to this pre-exercise supplement. Although the ergogenic benefits associated with high energy supplements have been demonstrated, the ability to improve subjective feelings of focus, awareness or improve reaction time is not clear. Anecdotal reports suggest that many athletes use high energy supplements prior

to an athletic contest to enhance these specific components. However, studies examining the ability of these pre-exercise energy supplements to improve reaction time and performance are scarce. Many pre-exercise high energy supplements www.selleckchem.com/products/nvp-bsk805.html consist of multiple ingredients that are proposed to either increase metabolic rate, enhance exercise performance or both. One such supplement is known as Redline Extreme™. It consists of various herbal and amino acid ingredients which include evodiamine, vinpocetine, yohimbine, hordenine, salbutiamine, beta-alanine, tyrosine,

and tyramine. These herbs and amino acids are suggested to work synergistically to enhance exercise performance. Thus, it is the purpose of this study to examine the effect of a popular, over-the-counter high energy supplement on physical performance and subjective feelings of energy, focus, awareness and fatigue in strength/power MYO10 athletes. Methods Subjects Twelve male strength/power

athletes (mean ± SD; 21.1 ± 1.3 y; 179.8 ± 7.1 cm; 88.6 ± 12.1 kg; 17.6 ± 3.3% body fat) volunteered for this study. Following an explanation of all procedures, risks and benefits each subject gave his written informed consent to participate in this study. The Institutional Review Board of The College of New Jersey approved the research protocol. Subjects with any known metabolic or cardiovascular disease, or psychiatric disorder were excluded. Subjects were also required to have been free of any nutritional supplements or ergogenic aids for the 6 weeks preceding the study, and were asked to refrain from taking any additional supplement during the duration of the study. Study design The study followed a randomized double-blind, crossover design. Subjects reported to the Human Performance Laboratory on two separate days. Each testing session was separated by one week. Subjects were instructed to refrain from consuming any caffeine products on the day of each testing session and from performing any strenuous physical activity for the previous 12 hours. In addition, subjects were instructed not to eat or drink for 3 hours prior to each trial. Following a 10 min resting period subjects were randomly provided with either the supplement (SUP) or the placebo (PL). On the subject’s second visit to the laboratory they were provided with the opposite treatment.
