简要总结
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.
详细描述
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.

结局指标
主要结局
Body composition
时间窗: 6 weeks
Lean body mass and body fatness will be evaluated using bioelectrical impedance
Circulatory hormone levels
时间窗: 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
时间窗: 6 weeks
Fasting blood samples were collected from the antecubital vein using standard procedures and then analyzed to establish concentration of myostatin and follistatin.
