Polyphenols and Their Potential Role in Preventing Skeletal Muscle Atrophy

Salucci, Sara, Falcieri, Elisabetta·2020·Nutrition Research

Abstract

Skeletal muscle atrophy is the consequence of various conditions, such as disuse, denervation, fasting, aging, and disease. Even if the underlying molecular mechanisms are still not fully understood, an elevated oxidative stress related to mitochondrial dysfunction has been proposed as one of the major contributors to skeletal muscle atrophy. Researchers have described various forms of nutritional supplementation to prevent oxidative stress-induced muscle wasting. Among a variety of nutrients, attention has also focused on polyphenols, a wide range of plant-based compounds with antioxidant and inflammatory properties, many of which have beneficial effects on human health and might retard skeletal muscle loss and function impairment. The purpose of this review is to describe polyphenol actions in skeletal muscle atrophy prevention. Published articles from the last 10 years were searched on PubMed and other databases. Polyphenols are important molecules that should be considered when discussing possible strategies against muscle atrophy. In particular, the collected studies describe, for each polyphenol subclass, the beneficial effect on muscle mass preservation in various skeletal muscle disorders. In these examples, the polyphenol compounds appear to mainly act by reversing mitochondrial dysfunction. Given that the current information on polyphenols is mostly restricted to basic studies, more comprehensive research and additional studies should be performed to clarify their mechanisms of action in improving skeletal muscle functions during atrophy.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Evidence from preclinical studies reveals nutraceuticals play a significant role in maintaining muscle health and are potential therapeutic agents in a broad range of muscle atrophy models.

    “Evidence from various preclinical studies has revealed that nutraceuticals play a significant role in maintaining muscle health and emerge as potential therapeutic agents in a broad range of muscle atrophy models [17,18].”
  • Phytochemicals play an essential role in the prevention and treatment of muscle atrophy, especially in reducing muscle protein degradation and promoting muscle protein synthesis.

    “Collectively, phytochemicals play an essential role in the prevention and treatment of muscle atrophy, especially in reducing muscle protein degradation and promoting muscle protein synthesis [17,18].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
