Abstract:
Objective: We performed a randomized double-blind study in distance runners to investigate the possible biological effects of daily consumption of soybean peptides. Methods: Twenty-one trained male distance runners, randomly divided into three groups: control group (C,n=7), carbohydrate supplementation group (CS, n=6) and soybean peptides supplementation group (SP,n=8), took part in the study.Their hormonal and serum metabolic profile was examined in a 4-week program of strenuous training. Daily training (4～6 hours per day, endurance and strength), food and medication were similar for all athletes. Group SP received a soy sports beverage supplement containing 8g soybean peptides and 35g carbohydrate once a day. Group CS received a sport drink containing 35g carbohydrate. Group C supplemented a placebo identical in appearance and flavor. Body weight, lean body mass, RPE, serum total testosterone, blood urea, hemogram, lactate dehydrogenase, creatine kinase and immunoglobulins were measured before, during and after the 4-week training program. Results: Data demonstrated that Group SP had an increase in body weight, especially in lean body mass and cyclic total testosterone level (P
