Abstract
  • The purpose of this study was to evaluate the effects of different peri-workout nutrition strategies on strength, body composition, and metabolism in trained females. Young, trained females (n=43) completed body composition and strength testing before and after training. Participants were randomized into three groups using baseline leg press strength; pre-exercise supplementation of a protein-carbohydrate shake (PRE), post-exercise supplementation (POST), or a control group (CON). Following baseline testing, participants were trained twice per week for six weeks using high intensity resistance training. At the first and last training, metabolic testing was completed before and after exercise. There were significant main effects for time for LM (p=0.003) and %fat (p<0.0005). All three groups experienced significant increases in strength. There were no significant between groups differences for metabolic measurements (p>0.05). These results demonstrate that peri-workout nutrition is potentially important for body composition, but either a PRE or POST strategy is effective.
