Study type | Interventional |
Post-resistance training high protein milk supplementation may be a viable method to elicit
muscular gains.
The investigators hypothesis is that high protein milk supplementation would improve skeletal
regulatory markers, hormonal responses and body composition in resistance-trained men.

Primary | Circulatory Myokines levels | Fasting blood samples were collected from the antecubital vein using standard procedures and then analyzed to establish concentration of myostatin and follistatin. | 6 weeks | |
Primary | Circulatory hormone levels | Fasting blood samples were collected from the antecubital vein using standard procedures and then analyzed to establish concentrations of testosterone, IGF-1, growth hormone, insulin and cortisol | 6 weeks | |
Primary | Body composition | Lean body mass and body fatness will be evaluated using bioelectrical impedance | 6 weeks | |
Secondary | Muscular Strength | Using a 1 repetition maximum test (defined as the maximal weight an individual can lift for only one repetition) for the bench press and back squat exercises | 6 weeks | |
Secondary | Muscular Power | Using the Wingate test | 6 weeks |
