Resistance Training and Milk Supplementation
- Conditions
- Muscular Hypertrophy
- Interventions
- Dietary Supplement: high protein milkDietary Supplement: Placebo
- Registration Number
- NCT04509297
- Lead Sponsor
- Marymount University
- Brief 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.
- Detailed 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.

Group Intervention Description High protein milk high protein milk Experimental: High protein milk consumption This arm involved High protein milk whole 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 high protein milk This arm involved 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. drink r High protein milk Placebo Experimental: High protein milk consumption This arm involved High protein milk whole consumption concomitant with 6 weeks of resistance training.

- Primary Outcome Measures
Name Time Method Body composition 6 weeks Lean body mass and body fatness will be evaluated using bioelectrical impedance
Circulatory hormone levels 6 weeks 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
Circulatory Myokines levels 6 weeks Fasting blood samples were collected from the antecubital vein using standard procedures and then analyzed to establish concentration of myostatin and follistatin.
- Secondary Outcome Measures
Name Time Method Muscular Strength 6 weeks 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
Muscular Power 6 weeks Using the Wingate test
