Publisher Summary This chapter reviews results obtained for muscles and fibers from
different species and different anatomical locations and assesses their similarities and …

Skeletal muscles comprise a substantial portion of whole body mass and are integral for
locomotion and metabolic health. Increasing age is associated with declines in both muscle …

Normal adult aging is associated with impaired muscle contractile function; however, to what
extent cross-bridge kinetics are altered in aging muscle is not clear. We used a slacken …

Abstract In the United Kingdom (UK), it is projected that by 2035 people aged> 65 years will
make up 23% of the population, with those aged> 85 years accounting for 5% of the total …

Skeletal muscle is a highly malleable tissue which, in youth, can respond to altered patterns
of contractile activity with remarkable adaptations. Since a reduction in adaptive capacity is …

One of the remarkable features of skeletal muscle is its adaptability. Skeletal muscle
adaptations are characterized by modifications of morphological, biochemical, and …

We review here the use and reliability of Hill-type muscle models to predict muscle
performance under varying conditions, ranging from in situ production of isometric force to in …

Although high-velocity contractions elicit greater muscle fatigue in older than young adults,
the cause of this difference is unclear. We examined the potential roles of resting muscle …

Following active muscle shortening, the steady-state isometric torque at the final muscle
length is lower than the steady-state torque obtained for a purely isometric contraction at that …

There is currently a limited amount of literature investigating the age-related changes in
eccentric muscle function in vitro. The present study uniquely uses the work loop (WL) …
