INTRODUCTION: Obesity affects postural sway during normal quiet standing; however, the
reasons for the increased postural sway are unknown. Improving muscular strength is …

The purpose of this study was to investigate the effect of lumbar extensor fatigue on postural
strategy in response to a balance perturbation. Anteriorly-directed force perturbations were …

Ageing impairs body balance and increases older adults' fall risk. Balance training can
improve intrinsic fall risk factors. However, age comparisons of muscle activity responses …

The ageing neuromuscular system is affected by structural and functional changes that lead
to a general slowing down of neuromuscular performance and an increased risk of falling …

The influence of age on spinal muscle activation patterns and its relation to kinematics is
poorly understood. We aimed at understanding age-related changes to spine and trunk …

The purpose of this study was to determine whether the mechanical contribution of ankle
muscles in the upright stance differed among young adults (YA)(n= 10, age:~ 24.3), elderly …

Background and purpose In aging, lower extremity muscle power is undoubtedly one of the
most important parameters of neuromuscular function implicating lower extremity physical …

In frail older subjects, the motor output of the antigravity muscles is fundamental in resisting
falls. These muscles undergo accelerated involutions when they are inactive and the risk of …

The purpose of this study was to examine age-related gait characteristics and their
associations with balance function in older adults. A total of 51 adult volunteers participated …

Background Muscle co-activation plays an important role in enhancing joint stability for
movement regulation during motor learning activities. In normal aging, greater muscle co …
