Protein and Amino Acid Metabolism During Exercise... 

Specific exercise such as weightlifting can increase muscle mass (9,10). While the potential to develop muscle mass is established, the metabolic changes that lead to these changes remain unclear. Relatively few studies have examined amino acid metabolism during exercise-induced hypertrophy. The primary reason for the lack of information is the absence of a convenient animal model for weightlifting studies. Human studies utilizing nonradioactive, stable isotopes have not yet been done. 

The material presented in the preceding sections concerns n ainly carbohydrate metabolism during exercise. Before considering fatty acid metabolisrn in exercise, a special carbohydrate should be covered — fructose.

One of the long-term benefits of exercise may be to increase the amount of superoxide dismutase in the cell. The elevated aerobic metabolism during exercise causes more ROS to be generated. In response, the cell synthesizes more protective enzymes. The net effect is one of protection, because the increase in superoxide dismutase more effectively protects the cell during periods of rest.
