Glutamine and athletic performance -

Overtraining Syndrome and Immunosuppresion During exercise or other times of physical stress such as fasting, severe injury, illness, or trauma the demand for plasma glutamine increases markedly. Enhanced Protein Synthesis and Prevention Of Muscle Atrophy A decreased ratio of testosterone to cortisol is believed to be directly responsible for losses in muscle mass since cortisol promotes the synthesis of glutamine synthetase.

Glucose Regulation and Glycogen Formation Glutamine also plays a role in glucose regulation. Growth Hormone The most notable study that showed glutamine had an effect on growth hormone levels was done by Welbourne when he administered an oral glutamine load to nine healthy subjects.

Some people prefer to take them before or after exercise, while others take them before bedtime. In one study, 31 people took either glutamine or a placebo during six weeks of weight training.

By the end of the study, both groups showed improved muscle mass and strength. Some research has reported that glutamine supplements may decrease muscle soreness and improve recovery after intense exercise. In fact, one study found that glutamine or glutamine plus carbohydrates can help reduce a blood marker of fatigue during two hours of running.

Glutamine does seem to offer some benefits for people who exercise regularly. The intestines are a critical part of the immune system, and glutamine plays an important role in maintaining intestinal health.

Glutamine is an energy source for intestinal and immune cells, and it helps to maintain the barrier between the inside of the intestines and the rest of the body. This prevents harmful bacteria or toxins from moving from the intestines into the rest of the body.

Additionally, glutamine is important for the normal growth and maintenance of cells in the intestine. By supporting intestinal health, glutamine indirectly helps to boost immunity.

This is why glutamine is often used as a natural supplement to improve immune system function. Glutamine is an important amino acid that is found in many foods. It is estimated that a typical diet contains 3 to 6 grams per day.
