Whey enhances the effect of strength training on muscle mass, collagen does not
Study
The women consumed about 1 gram of protein per kilogram of body weight every day through their regular diet. The shakes increased this to about 1.7-1.8 grams per kilogram of body weight per day.
The researchers determined how much muscle tissue the women built up in their leg muscles before the experiment started and after 5 days of supplementation. Before and after 5 days of supplementation, they had the women train their thighs on a leg-extension machine, and again measured the build-up of muscle protein in the leg muscles in the following hours.
Results
Conclusion
"Consumption of whey protein when consumed in conjunction with resistance exercise resulted in a further stimulation of muscle protein synthesis, reinforcing the importance of resistance exercise in the maintenance of skeletal muscle health."
"Importantly, we also show that resistance exercise in combination with low-quality collagen protein was not sufficient to elevate rates of myofibrillar muscle protein synthesis above baseline in healthy older women indicating that the selection of protein sources for older women may be of great significance."
