Muscle fibre capillarization is a critical factor in muscle fibre hypertrophy during resistance exercise training in older men

BACKGROUND Adequate muscle fibre perfusion is critical for the maintenance of muscle mass; it is essential in the rapid delivery of oxygen, nutrients and growth factors to the muscle, stimulating muscle fibre growth. Muscle fibre capillarization is known to decrease substantially with advancing age. However, whether (relative) low muscle fibre capillarization negatively impacts the muscle hyper...

Nox4 Is Dispensable for Exercise Induced Muscle Fibre Switch

INTRODUCTION By producing H2O2, the NADPH oxidase Nox4 is involved in differentiation of mesenchymal cells. Exercise alters the composition of slow and fast twitch fibres in skeletal. Here we hypothesized that Nox4 contributes to exercise-induced adaptation such as changes in muscle metabolism or muscle fibre specification and studied this in wildtype and Nox4-/- mice. RESULTS Exercise, as in...

Increased Skeletal Muscle Capillarization Independently Enhances Insulin Sensitivity in Older Adults After Exercise Training and Detraining

Intramuscular signaling and glucose transport mechanisms contribute to improvements in insulin sensitivity after aerobic exercise training. This study tested the hypothesis that increases in skeletal muscle capillary density (CD) also contribute to exercise-induced improvements in whole-body insulin sensitivity (insulin-stimulated glucose uptake per unit plasma insulin [M/I]) independent of oth...

Jitter in the muscle fibre.

Direct stimulation of muscle fibres with a regular 10 Hz rate, three computer generated random rhythms and a sequence of voluntary discharges was used to quantify the interdischarge interval (IDI) dependent jitter due to velocity recovery function (VRF). This jitter was found to depend on conduction time and strength of VRF, but not on propagation velocity. The results suggest that in the usual...

Fuel selection, muscle fibre.

The fuel selection of muscle fibres at rest is dependent on substrate availability. Increased lipid availability results in an increase citrate concentration with inhibition of glycolysis. Fat utilization also increases the concentration ratio acetyl-CoA:CoASH, with inhibition of PDH transformation to the active form. The result is an inhibition of carbohydrate utilization in conformity with th...
