Hypertrophic signalling in human skeletal muscle : impact of exercise, ageing and dairy proteins

Ý-lactoglobulin enriched whey protein isolate, but not carbohydrate, increased growth signalling in human skeletal muscle when consumed in conjunction with resistance exercise. Ageing did not impair the anabolic signalling response; however this response was attenuated after training. These findings help identify strategies to prevent, or delay the onset of sarcopenia.
