Chronic Moderate Exercise: A Potential Therapeutic Approach for Enhancing Klotho Levels and Alleviating Peripheral Neuropathy in Metabolic Syndrome

Abstract

Metabolic syndrome (MetS) is a multifaceted condition characterized by obesity, insulin resistance, and chronic inflammation, often associated with peripheral neuropathy and reduced levels of Klotho, a protein with significant anti-aging and metabolic regulatory functions. Chronic moderate exercise (CME), a sustainable lifestyle intervention, has emerged as a promising non-pharmacological approach to mitigating these complications. This review explores the effects of CME on Klotho levels and peripheral neuropathy status in individuals with MetS, highlighting the molecular and physiological mechanisms involved. CME has been shown to upregulate Klotho expression through pathways involving oxidative stress reduction, inflammation modulation, and improved insulin sensitivity. By enhancing Klotho levels, CME helps counteract systemic inflammation, oxidative damage, and vascular dysfunction, which are central to the pathogenesis of peripheral neuropathy in MetS. Furthermore, CME promotes the release of neurotrophic factors such as nerve growth factor (NGF), supporting nerve regeneration and repair. The review synthesizes evidence from preclinical and clinical studies, demonstrating that CME improves nerve conduction velocity, alleviates neuropathic pain, and restores sensory function in individuals with MetS. These benefits are attributed to CME-induced improvements in mitochondrial function, vascular health, and systemic metabolic parameters, all of which contribute to peripheral nerve protection.

Despite these promising findings, gaps remain in understanding the dose-response relationship between CME and Klotho regulation, as well as the long-term effects on neuropathy progression. This article highlights the need for further research to optimize exercise protocols, investigate the interaction between Klotho and neuropathy-related pathways, and validate findings in diverse populations. By integrating CME into comprehensive management strategies, significant strides can be made in improving quality of life for individuals with MetS.
