Effects of consuming soy and whey protein

It is believed that proteins are of great importance for all athletes. It is logical that the growing popularity of nutritional supplements among athletes has led to the fact that the group of experts became interested in this phenomenon. There has been extensive research under the capacious name "the Effects of consumption of soy and whey protein for men". The research results were published in the Journal of the American College of nutrition. The publication is a confirmation of previously conducted research works that were devoted to the study of the effects of consumption of whey and soy protein on indicators of testosterone hormone in the blood in response to training.

William J.Kraemer, who stood at the head of the study shows that the provided information was unique about the use of protein practicing men. The experiment involved 10 men who trained with weights. Age the percentage of men ranged from 20 years or more.

A group of men divided into three types:

• whey isolate;
• soy protein isolate;
• control group a placebo.

Other supplements was not used for food. Those citizens who consider themselves vegetarians or sitting on a high-protein diet, were excluded from the analysis. Within two weeks, the participants ate 20 grams of one of the dietary supplements. Every morning after their adoption, they performed the squats with the weights that lay in six approaches of 10 repetitions using a load of 80 percent of the maximum score. As a result of experiments the results obtained clearly showed the researchers that the consumption of soy protein lowered the rate of testosterone in serum. For those men who were in the group of whey protein, it was possible to observe the weakening of the release of cortisol. On this basis, supplementation of protein can alter the physiological response properties to workout with the weights. It all depends on the type of the used protein. So say the creators of the study.
