Whey Protein Builds Strength

Scientist have debated the proein requirements of athletes for more than 100 years. Nutritionists recommend 0.9 grams of protein per kilogram of bodyweight per day, but serious body builders need more – about 1.5 grams per kilogram. The type of protein in the diet influences gains in strength and muscle mass in weight-training athletes. Last month we reported that experienced weightlifters who took a whey protein supplement during an intense 10-week weight training program increased bench press and leg press strenght an lean mass ( Journal Strength Conditioning Reasearch, 28:643-653, 2006). An Australian study found similar results. Bodybuilders given a whey isolate supplement ( 1.5 grams per kilogram per day ) made larger gains in lean mass and strength and experienced greater fat loss than subjects given casein supplement. Neither supplement increased glutamine, which becomes depleted during intense training. A whey protein supplement helps maximize training gains in bodybuilders ( International Journal Sports Nutrition, 16:494-509, 2006 )
