Background: The cardiovascular (CV) and metabolic health benefits or risks associated with consumption of multi-ingredient performance enhancing supplements (MIPS) in conjunction with periodized resistance training (RT) in resistance trained men are unknown. This population is a major target audience for performance supplements, and therefore, the purpose of this study was to investigate the combined effect of RT and commercially available pre- and post-exercise performance supplements, NO-Shotgun® (SHOT) and NO-Synthesize® (SYN), respectively, on CV risk and body composition in resistance trained men. Methods: Twenty-four resistance trained men completed 6 weeks (3 times/week) of whole-body periodized RT while either ingesting SHOT 30 min pre-exercise and SYN immediately post-exercise or an isocaloric maltodextrin placebo (PL) 30 min pre-exercise and immediately post-exercise. Before and after 6 weeks of RT and supplementation, resting heart rate (HR), blood pressures (BP), total body fat, android fat, gynoid fat, fat-free mass (FFM) and fasting blood measures of glucose, lipids, nitrate/nitrite (NOx), cortisol, and high sensitivity C-reactive protein (CRP) were measured. Statistical analysis was conducted using a 2 x 2 (group x time) repeated measures ANOVA. Significance was set at p<0.05. Results: There was no group x time interaction for HR, BP, blood glucose, lipids, NOx, CRP, cortisol concentrations or body fat. However, there was a time effect where significant decreases in body fat (MIPS: -1.2±1.2%; PL: -0.9±1.1%), android fat (MIPS: -1.8±2.1%; PL: -1.6±2.0%), and gynoid fat (MIPS: -1.3±1.6%; PL: -1.0±1.4%) for both groups were observed. FFM increased in both groups, with MIPS increasing significantly more than the PL group (4.2% vs. 1.9%, p=0.0247). Conclusions: 6 weeks of MIPS ingestion and periodized RT does not alter CV health parameters or blood indices of health or body fat more than a PL treatment in healthy, resistance-trained men. However, MIPS significantly increased FFM. / A Thesis submitted to the Department of Nutrition, Food, and Exercise Sciences in partial fulfillment of the requirements for the degree of Master of
