Clinical Trial Summary

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.


Description:

The aim of this investigation was to compare the effects of high protein milk supplementation (daily and after training sessions) during 6 weeks of resistance training on skeletal muscle regulatory markers, hormonal responses and body composition in resistance-trained men. Specific aims of the study are to:

To investigate the extent to which high protein milk supplementation will improve anabolic factors, lean body mass, fat mass and decrease catabolic markers after 6 weeks of resistance training in resistance-trained men.

Intervention

Dietary Supplement:
high protein milk
This intervention consisted of high protein milk consumption concomitant with 6 weeks of resistance training. Subject ingested consumed 1 x 250 mL immediately after resistance training and 1 x 250 mL half an hour before bedtime.
Placebo
This intervention consisted of the consumption of a maltodextrin drink with a 9% solution with a vanilla flavor concomitant with 6 weeks of resistance training. Subject ingested consumed 1 x 250 mL immediately after resistance training and 1 x 250 mL half an hour before bedtime.

Outcome

Type Measure Description Time frame Safety issue
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
