Background
Nutritional supplements intended for consumption in proximity to resistance exercise are extremely popular among young males and athletes. Common components of these products include caffeine, creatine monohydrate, β-Alanine (BA), citrulline, L-arginine, branched chain amino acids (BCAA), and whey protein in proprietary blends. To date, there have been no investigations of the potential health risks or benefits associated with consumption of these products over the course of a resistance training (RT) regimen despite anecdotal reports to health complications. The purpose of this study was to investigate the effect of the commercial sports nutritional supplements NO-Shotgun® (SHOT) and NO-Synthesize® (SYN) (Vital Pharmaceuticals, Inc., Davie, FL) on cardiovascular risk, blood lipids, and glucose in resistance trained men following 6weeks of supplementation and concurrent resistance exercise.
