Slowing of the contractile properties of skeletal muscle is one of the characteristic features of
fatigue. First studied as a slowing of relaxation from an isometric contraction, it has become …

Non‐technical summary Prolonged muscle activity leads to a reduction of mechanical power
and force output which is commonly indicated as muscular fatigue. The development of …

Slow relaxation from an isometric contraction is characteristic of acutely fatigued muscle and
is associated with a decrease in the maximum velocity of unloaded shortening (Vmax) and …

We have studied the force-velocity relation and the relaxation speed in intact, single fibres
from Xenopus during fatigue produced by repeated tetani. Slack tests were used to obtain …

The force produced by muscles declines during prolonged activity and this decline arises
largely from processes within the muscle. At a cellular level the reduced force could be …

Skeletal muscles are used in several different ways. Often they form variable-length struts,
stiffening joints and appendages for such tasks as standing or holding objects. During …

Muscle performance declines during prolonged and intense activity; important components
are a reduction in force production and shortening velocity and a prolongation of relaxation …

It is well established that muscle fatigue, defined as a decline in maximal force generating
capacity, is a common response to muscular activity. To what extent metabolic factors …

The objective of this study was to estimate the limitations imposed by the kinetics of
activation and relaxation on the ability of slow skeletal muscle to produce mechanical work …

1. We have investigated the loss of power seen during high‐intensity exercise of human leg
muscles such as might occur during sprinting. Subjects exercised the quadriceps and …
