PS has been shown to reduce stress and increase performance in runners cyclists and golfers. The purpose of this study was to investigate the effects of a PS containing formulation on cognitive function mood and endocrine response before and after intense resistance exercise. Methods 18 lower body resistance trained college aged males ingested 14 days of supplement IQPLUS Focus providing 400 mg of soy-derived PS and a Placebo PL in a randomized double-blind placebo controlled crossover manner. Following 14 days of supplementation participants performed an acute bout of lower body resistance training. Mood Profile of Mood States POMS and cognitive function Serial Subtraction Test SST were measured prior to 5 minutes after and 60 minutes after exercise. Venous blood samples were collected prior to and 5 15 25 40 and 60 minutes after exercise. Blood samples were analyzed for plasma cortisol and testosterone. Data were analyzed using repeated measures ANOVA. Results PS supplementation significantly reduced the time needed for a correct calculation on the SST by 20 reduced by s per calculation PL s PS s p and reduced the total amount of errors by 39 PL .69 PS .78 .27 p and increased the amount of correct calculations by 13 PL PS p prior to or in response to exercise compared to PL.
