Special Issue Information
Dear Colleagues,
The high oxygen consumption and metabolic rate of muscle fibers cause them to continuously generate reactive oxygen and nitrogen species (RONS) during rest, and their production is increased during muscle contraction. However, an imbalance between the antioxidant system and the generation of RONS triggers oxidative stress, which provokes damage to molecules and affects specific functions such as excitation–contraction coupling. Skeletal muscles are equipped with various enzymatic and non-enzymatic antioxidants, including superoxide dismutase, catalase, glutathione peroxidase, γ-glutamylcysteine synthetase and heme oxygenase-1. Accumulating evidence has shown that antioxidants can achieve optimal concentrations of RONS to perform physiological signal transduction in muscle. They function as biosensors of RONS and render skeletal muscle extremely flexible in both health and disease. As an example, RONS play a very important role in protein turnover, which can promote muscle hypertrophy and regeneration.
This Special Issue aims to provide a comprehensive overview of the skeletal-muscle-focused antioxidant responses accompanying both physiological (e.g., exercise) and pathological challenges. The latter involves muscle injury, metabolic diseases, muscle dystrophy, carcinogenesis, systemic inflammation, inactivity or immobilization, to only name a few disorders capable of altering redox balance. Authors are invited to submit their latest original and innovative research findings or review articles with new insights into the association between scavenging capacity and cell signaling, muscle function and muscle metabolism in the response to stressors. Both human and animal studies are welcome.
We 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 100 words) can be sent to the Editorial Office for announcement on this website.
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. Antioxidants is an international peer-reviewed open access monthly 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.
