Is there a better type of protein to preserve hard-earned muscle mass during times of inactivity? The answer – yes!
A recent study tested the ability of rapidly digested whey protein and slowly digested casein protein to stimulate net whole-body protein synthesis during prolonged physical inactivity.
This study used 8 young male volunteers after they consumed casein protein or whey protein after 12 to 14 days of experimental bed rest.
Rates of phenylalanine hydroxylation were measured by primed-constant oral administration of tracers of tyrosine and phenylalanine for 3 hours in the post-absorptive state and 6 hours after an isonitrogenous meal containing sucrose (0.27 grams/kg) and casein or whey (0.40 grams/kg).
Net protein synthesis was calculated. During bed rest, net protein synthesis was significantly greater after the consumption of whey protein than after casein protein consumption. The rapidly digested whey protein was more efficient than the slowly digested casein in increasing net protein synthesis during short-term bed rest in young men. The whey protein promoted greater protein synthesis.
During illness or injury, most bodybuilders and athletes don’t use supplements because they think there is no benefit. In fact, the opposite is true. The results of this study suggest that using VP2 Whey Isolate is highly effective at preserving valuable muscle mass during times of inactivity such as illness or injury. And this study shows if more effective than casein protein.
Want to make sure you take advantage of this latest science? It’s simple, on days you don’t train, have a VP2 shake in the morning and another VP2 shake in the evening. And just as important, on your off weeks or during times you are forced to take time off, make sure you have a couple of VP2 shakes a day, and you’ll maintain the valuable muscle mass you have worked so hard to build. We all know how quickly your body gives up muscle when you don’t train, but it doesn’t have to be like that.
