Overview

The coexistence of obesity and sarcopenia results in sarcopenic obesity, a high-risk geriatric condition associated with metabolic perturbations and several co-morbidities. Despite the rising numbers of older adults diagnosed with sarcopenic obesity, few studies have characterized this condition on the muscle cell and systemic level. This study sought to comprehensively assess the influence of sarcopenic obesity on muscle and blood-related parameters and compare it to non-sarocopenic obese and non-sarcopenic lean older adults.
