When you hydrolyze a protein, you break larger pieces down into smaller pieces. What might this process offer active adults who incorporate hydrolyzed whey into their supplementation strategy? A study published in Journal of the American College of Nutrition offers some interesting findings.
Researchers gave 56 men with weight training experience a 30 gram serving of whey protein concentrate or hydrolyzed whey concentrate twice daily for 8 weeks. During this time, subjects performed 2 upper body training sessions and 2 lower body training sessions each week.
After the training period, upper body one rep max (1RM) increased 4% to 7% and lower body 1RM increased 24% to 35% with no significant differences between groups. Subjects who got hydrolyzed whey concentrate lost an average of 6% body fat. Subjects who received a carbohydrate placebo gained around 4.4% body fat.
