Waist and hip circumferences were
measured using a gulick measuring tape having a calibrated tension device to the nearest .25 inch. Waist measurements see more were taken at the minimal circumference of the abdomen and hip circumference was measured at the maximal gluteal protrusion of the buttocks. Fat free mass was calculated as body weight minus fat mass. Diet Analysis During the initial screening process subjects were instructed by a registered dietitian how to maintain proper 3-day food records. Each subject completed a food record prior to beginning the exercise program and at the end of each exercise block (every 3 weeks) for a total of 5 diet records throughout the study. Records were analyzed utilizing Nutritionist Pro software (First Databank, San Bruno, CA). Based on data from diet records, the registered dietitian provided feedback to assist each subject in maintaining a protein intake equivalent between groups to approximate 1.2 g/kg body mass/day (including
the supplement). Experimental Protocol Subjects were initially screened by a phone interview and eligible candidates were invited LEE011 to visit the laboratory, after a 12-hour fast. Potential subjects obtained additional information about the study and reviewed and signed informed consent. Subjects provided a blood sample for a blood lipid profile and blood glucose concentration The lipid profile included total cholesterol, high and low density lipoprotein cholesterol (HDL-C and LDL-C, respectively), and triglycerides using the Cholestech L· D·X® (Cholestech Corporation, Hayward, CA). Height and body mass were measured to calculate BMI. If the inclusion
criteria were met the participant was scheduled for a baseline blood draw in The Center for Preventive Medicine at the University at Buffalo, after a 12 hour fast (except for water) and after abstaining from caffeine, alcohol and exercise for the previous 24 hours. During this visit, body composition was measured and each subject was given diet record forms and instructed on proper completion. Subjects were also instructed how to Ergoloid mix (with 8 oz water or fruit juice) and to consume individual protein packets on a daily basis. Subjects were instructed that the timing of consumption of the supplement was critical. On workout days the supplement was to be taken within 60 minutes of the scheduled workout and on “”off”" days, at approximately the same time of day as the workout days. Subjects were instructed to limit other soy containing products in their diet as well as to maintain protein intakes as close to 1.2 g/kg body mass/day as possible (from feedback given after analysis of each of the five 3-day diet records). The resistance exercise program was reviewed and each subject underwent a medical evaluation by a physician to determine appropriateness to participate in the study.
