Effect of proteins on skeletal muscle mass
When it comes to the preservation of skeletal muscle mass in advanced age, the question is, which proteins are effective to maintain, are animal or vegetable proteins.
In a study of the King’s College London, it was found that animal proteins are apparently more effective for maintenance of muscle mass, as Protein from soy or wheat. The results were at the event, The Physiological Society’s virtual early career conference Future Physiology 2020 is presented.
Why build muscles in old age?

A main reason for muscle wasting in old age in healthy individuals is due to a reduction in the amino acids built up muscle proteins, according to the research group. These amino acids come from proteins that are taken up from food, or from proteins that are formed during the Sport.
Protein from soy and wheat, or animal sources?
The number of vegetarian or vegan living people continues to grow. A plant-based diet is definitely very good for the environment, but the question remained open, how effective such a diet to maintain the muscle mass in increasing age? In order to clarify this question, the examined, the researchers proteins from soy especially and wheat and compared this with animal sources.
Higher dose of animal proteins necessary

In a comparison of animal proteins and proteins from soy and wheat showed that a larger dose of these plant proteins is required to achieve a comparable response in muscle building. A simple Transition from an animal to a plant-based diet without adaptation of the total protein intake would have a direct effect likely to be detrimental to the muscle health during aging, explain the researchers.
The diet should be balanced
A more balanced and less extreme approach to Changing dietary behaviour seems to be to maintain muscle mass in old age at best, more reported the research team. In other words, the consumption expressed: both animal and vegetable proteins should be combined, explain the researchers in a press release of the study results.
How quickly muscles amino acids build?
It is carefully controlled laboratory studies have been conducted on voluntary Participants, the vegetable proteins compared to animal sources of protein consumed. In order to analyze changes in the muscles of the Participants applied the research group various techniques, for example, the method of stable isotopes, blood samples and skeletal muscle biopsies. The research group wanted to find out how quickly the muscles of amino acids were constructed.
Animal Protein is more effective
The results show that on a gram-for-gram Basis of animal proteins are actually more effective than vegetable proteins, with the support of the preservation of skeletal muscle mass with advancing age, so the conclusion of the research team.
Other plant-based proteins should be investigated
The research work dealt exclusively with two vegetable protein sources (soy and wheat). Therefore, further studies are appropriate, what are the other promising plant proteins of oat, Quinoa and Corn include. (as)
