Effects of old age on human skeletal muscle energetics during fatiguing contractions with and without blood flow

IR Lanza, RG Larsen… - The Journal of physiology, 2007 - Wiley Online Library
We recently reported lower glycolytic flux (ATPGLY) and increased reliance on oxidative
ATP synthesis (ATPOX) in contracting muscle of older compared to young humans. To …

A reduced activity model: a relevant tool for the study of ageing muscle

O Perkin, P McGuigan, D Thompson, K Stokes - Biogerontology, 2016 - Springer
Skeletal muscle mass is in a constant state of turnover, and atrophy is the result of a shift in
the balance of muscle protein synthesis and breakdown resulting in net muscle protein loss …

Single muscle fibre contractile function with ageing

GJ Grosicki, CS Zepeda… - The Journal of …, 2022 - Wiley Online Library
Ageing is accompanied by decrements in the size and function of skeletal muscle that
compromise independence and quality of life in older adults. Developing therapeutic …

Age-induced oxidative stress: how does it influence skeletal muscle quantity and quality?

CW Baumann, D Kwak, HM Liu… - Journal of Applied …, 2016 - journals.physiology.org
With advancing age, skeletal muscle function declines as a result of strength loss. These
strength deficits are largely due to reductions in muscle size (ie, quantity) and its intrinsic …

The clinical impact and biological mechanisms of skeletal muscle aging

Z Aversa, X Zhang, RA Fielding, I Lanza… - Bone, 2019 - Elsevier
Skeletal muscle is a highly plastic tissue that remarkably adapts to diverse stimuli including
exercise, injury, disuse, and, as discussed here, aging. Humans achieve peak skeletal …

Muscle atrophy and weakness with aging: contraction-induced injury as an underlying mechanism

JO Holloszy, JA Faulkner, SV Brooks… - The Journals of …, 1995 - academic.oup.com
In old compared with young animals, muscle mass is decreased by 30% to 40%, and
maximum force and power are decreased to an even greater extent. The age-related …

Plasticity of dynamic muscle performance with strength training in elderly humans

ND Reeves, CN Maganaris… - Muscle & Nerve: Official …, 2005 - Wiley Online Library
Data are scarce relating to the plasticity with strength training of dynamic muscle
performance in older humans. Hence, we investigated alterations in the torque–velocity …

Innervation and neuromuscular control in ageing skeletal muscle

RT Hepple, CL Rice - The Journal of physiology, 2016 - Wiley Online Library
Abstract Changes in the neuromuscular system affecting the ageing motor unit manifest
structurally as a reduction in motor unit number secondary to motor neuron loss; fibre type …

A predictive model of fatigue in human skeletal muscles

J Ding, AS Wexler… - Journal of applied …, 2000 - journals.physiology.org
Fatigue is a major limitation to the clinical application of functional electrical stimulation. The
activation pattern used during electrical stimulation affects force and fatigue. Identifying the …

Human ageing: impact on muscle force and power

H Degens - Muscle and exercise physiology, 2019 - Elsevier
During ageing, muscle loses much of its power-generating capacity. This is attributable to
both a decrease in force-generating capacity and a reduction in the shortening velocity. The …
