Resistance Training and Milk Supplementation

Not Applicable

Completed

• Conditions: Muscular Hypertrophy

• 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.

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
