چکیده
Methods Twenty-two males (n = 13) and females (n = 9) ages 20– 36 years (23.68 +/3.91), volunteered as subjects. Each subject performed two VO2max treadmill tests within two weeks of each other. Administration of the trials was double-blinded and randomized with half of the participants ingesting PRX1 during the first trial and PRX2 during their second trial with the product order being reversed for the other subjects performing both exercise trials. In this crossover design, each subject ingested the PRX1 or PRX2 exactly 20 minutes before each exercise bout. VO2max, maximal heart rate (HR), time to exhaustion (Time), respiratory exchange ratio (RER), and fat substrate utilization (%), during graded exercise testing were evaluated.
