The causes of muscle loss

The causes of muscle loss

Most researchers believe there are many factors other than age related activity changes that contribute to this condition. Amongst these are the metabolic changes that take place within the muscle tissue itself. Recent research has found that older individuals may not be getting enough protein in their diet and that they do get, may not be efficiently utilized in building muscle tissue. This effect may be caused by an altered response to the available and diminishing hormones. Be this as it may, older muscle still responds well to amino acids particularly to the essential and branched chain amino acids (BCAA) due to their ability to intensely stimulate protein synthesis in older individuals.

Further literature review indicates this is due to leucine [1], an essential amino acid that is not manufactured by the body and has to be obtained from food sources. So if you are considering protein supplementation, then adding in extra branched chain amino acids, essential amino acids with a little bit of extra leucine may be in order.

Is becoming more evident that older people should take in more protein by raising the limit to a least 1.3 g per kilogram. Another aspect of the protein in question is a type of protein that your taking. For example, whey protein is assimilated better than soy protein. Most plant-based proteins are not sufficiently converted; therefore, more is needed to get the minimum amount.

Additionally, before leaving the dietary issue of protein, the timing of the protein intake may make a difference. Most strength research indicates a consuming 25 to 30 grams of protein 10 to 15 minutes before and 10 to 15 minutes after an intense training session is the most beneficial.

Before doing so, check with your doctor or a registered dietitian because many older people may have impaired kidney function and the extra protein can exacerbate this condition.

Along with less protein intake comes a diminishing hormone production.

These lower levels of hormones, combined with some pro-inflammatory compounds and the free radicals, which are known to damage the cells, can also promote the wasting of muscle tissue which affects muscle fibers. Severe dieting, illness and/or extended bed rest also accelerates muscle loss.

A final thought in this matter is to consider taking 800-1000 international units of vitamin D a day or more if your Dr. tells you that your blood tests have indicated that it is low. Studies of various populations have shown a link between low vitamin D levels and increased risk of sarcopenia.

Stay strong, and remain passionately committed to your hearts chosen path.

[1] Leucine works with the amino acids isoleucine and valine to repair muscles, regulate blood sugar, and provide the body with energy. It also increases production of growth hormones, and helps burn visceral fat, which is located in the deepest layers of the body and the least responsive to dieting and exercise. http://www.vitaminstuff.com/amino-acid-leucine.html
