Combined effects of natural products and exercise on apoptosis pathways in obesity-related skeletal muscle dysfunction.

Abstract

Obesity and related metabolic disorders are closely linked to increased apoptosis in skeletal muscle, leading to muscle degeneration, insulin resistance, and the progression of diseases such as type 2 diabetes and sarcopenia. This review explores the combined effects of natural products, including resveratrol, curcumin, and quercetin, and physical exercise on modulating apoptosis pathways in skeletal muscle. Both natural products and regular physical activity independently reduce oxidative stress and improve mitochondrial function, thereby regulating the balance between pro-apoptotic and anti-apoptotic signals. When combined, these interventions amplify their protective effects on muscle health, promoting mitochondrial biogenesis, reducing apoptosis, and enhancing muscle regeneration. This review also discusses the molecular mechanisms by which these strategies influence apoptosis, with a focus on the Bcl-2 pathway, and explores the clinical implications for the prevention and treatment of obesity-related diseases. The synergistic benefits of combining exercise with natural product supplementation offer a promising therapeutic approach for managing metabolic disorders, preserving muscle function, and improving overall metabolic health.
