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

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
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 …

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 …
