Effects of resistance exercise volume and nutritional supplementation on anabolic and catabolic hormones

Abstract. Seven resistance-trained men performed six bouts of resistance exercise, each separated by at least 1 week, in a crossover design. High, moderate and low volumes of exercise were used, each performed twice and followed immediately post-exercise by either a placebo or carbohydrate-protein supplementation. All bouts of resistance exercise were performed using a load equal to 100% of each subject's ten-repetition maximum (10-RM), and all rest periods between sets of exercise were 1 min. Blood was obtained before and at intervals after exercise until 120 min post-exercise. Lactate levels were significantly (P
