Background: Protein intake is a popular dietary strategy designed to optimize the adaptive response to exercise. The strategy involves consuming protein in and around a training sessions in an effort to facilitate muscular repair, remodelling, and thereby enhance post-exercise strength and muscle anabolism. The Purpose of the current study was to investigate the effect of whey protein and resisted exercise on anabolic and catabolic hormones regarding growth hormone, testosterone and cortisol and muscle strength in normal subjects. Materials and Methods: Sixty normal male subjects, their mean age was 18.82±0.72 years, mean weight was 68.08±5.36 Kg, mean height was 176.63±4.61 cm and mean BMI was 21.83±1.58 Kg/m² were assigned randomly into two equal groups. Data obtained from both groups 75% of the one repetition maximum before starting, after three weeks and at the end of the sixth week and blood analysis to test anabolic and catabolic hormones (testosterone, growth hormone and cortisol) were statistically analysed and compared pre with post training program. Study group received whey protein and resisted exercise. Control group received only resisted exercise. Resistance exercise was done for both upper limbs (biceps and triceps) using dumbbell according to the one repetition maximum. Three sets was done with 10 repetition for each set. The training protocol consisted of three sessions per week for six weeks for both groups. Whey protein was taken by mouth following the exercise in a dose of 1.2 g/kg/day for the study group
