Aspects of muscle performance, mobility limitations, excercise interventions and cognitive functioning in older adults

Abstract

In section A, two studies were conducted to systematically investigate and compare the cross sectional and longitudinal physiological determinants of the age-related loss of lower extremity muscle power in healthy and mobility-limited older adults (n = 93). Computed tomography was utilised to assess mid-thigh body composition and measures of muscle quality. Surface electromyography was used to assess neuromuscular function and muscle biopsies were taken to evaluate intrinsic single muscle fibre contractile properties.
