Protein and Amino Acid Intake on Skeletal Muscle Metabolism

Dear Colleagues,

There are many studies on muscle metabolism, focusing on the effect of amino acids and protein intake on supporting muscle mass and muscle tissue function in the event of altered metabolism. The skeletal muscles have an essential role as a major energy storage depot, in movement, and in regulation of body temperature homeostasis. Thus, an impaired metabolism of striated muscle tissue can generate numerous primary or secondary pathologies in some diseases. It is essential to maintain a proper functioning of skeletal muscle, as well as keeping normal muscle mass both in the case of muscle diseases and in muscle cachexia due to cancer, diabetes, neurodegenerative diseases, etc. There is also a scientific interest in the morphological and physiological maintenance of skeletal muscles in sarcopenia in the aging population. All of these must take into account the changes that occur in the cellular metabolism of the striated muscle fibers and how it can be regulated by the intake of amino acids and proteins. It is known that amino acids and proteins are the building blocks for muscle growth and repair, and their supplementation enhances muscle protein synthesis needed for preserving muscular mass during aging, illness, and resistance training. They are also vital for muscle energy and myokine production.

The aim of this Special Issue is to find cutting-edge research on these developments. We are encouraging researchers to publish their findings that will ultimately highlight the advances in protein and amino acid intake on skeletal muscle metabolism. Contributors are encouraged to submit original and review papers dedicated to these topics.

I look forward to receiving your contribution.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Nutrients is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
