Abstract

Aging is associated with inflammatory chronic conditions such as obesity, cardiovascular disease, insulin resistance, and arthritis. Sarcopenia-muscle loss with aging-is multifactorial with contributing factors that may include loss of α-motor neuron input, changes in anabolic hormones, decreased intake of dietary protein, and decline in physical activity. Research findings suggest that sarcopenia is a smoldering inflammatory state driven by cytokines and oxidative stress. Elevated levels of interleukin-6 and C-reactive protein are often detected. Sarcopenic obesity manifests the added inflammatory burden of adiposity and associated adipokines. Potential interventions for sarcopenia include nutritional supplements, physical activity/resistance exercise, caloric restriction, anabolic hormones, anti-inflammatory agents, and antioxidants. A key question is whether sarcopenia is truly a distinct syndrome or a milder form of a cachexia continuum.
