Whey Protein - Benefits For Muscle Building

Benefits For Muscle Building

The effects of whey protein supplementation on muscle growth in response to resistance training are debatable. One study demonstrated some increase in lean body mass and strength in men supplementing whey protein vs. no supplementation, while another study found greater increases in strength in a group supplementing whey compared to another group supplementing casein, which could be evidence of whey protein's superior amino acid profile. However, other research exists that show little to no benefit of whey protein supplementation. The authors of one study concluded that "young adults who supplement with protein during a structured resistance training program experience minimal beneficial effects in lean tissue mass and strength,", although it did not control for other sources of protein in the participant's diets. The timing of protein supplement ingestion may not have any significant effects on strength, power, or body-composition. A study of elderly men found supplementation with whey protein after exercise improved muscle protein synthesis.
