Age-related alterations of skeletal muscle are numerous and present inconsistently, and the
effect of their interaction on contractile performance can be nonintuitive. Hill-type muscle …

Key points Muscle fatigue can be defined as the transient decrease in maximal force that
occurs in response to muscle use. Fatigue develops because of a complex set of changes …

Efficient muscle-tendon performance during cyclical tasks is dependent on both active and
passive mechanical tissue properties. Here we examine whether age-related changes in the …

With aging, motoneurons and muscle tissue undergo significant changes, which influence
function in terms of strength, mobility, and overall independence. Mathematical modeling …

Natural adult aging is associated with declines in skeletal muscle performance, including
impaired Ca 2+ sensitivity and a slowing of rapid force production (rate of force …

Aging in humans is associated with a loss in neuromuscular function and performance. This
is related, in part, to the reduction in muscular strength and power caused by a loss of …

Tendons transfer forces produced by muscle to the skeletal system and can therefore have a
large influence on movement effectiveness and safety. Tendons are mechanosensitive …

Purpose The purpose of the study was to determine:(1) the relationship between ankle
plantarflexor muscle strength and Achilles tendon (AT) biomechanical properties in older …

The generation of muscle-actuated simulations that accurately represent the movement of
old adults requires a model that accounts for changes in muscle properties that occur with …

Overall reductions in muscle strength typically accompany the aging process. However,
older adults show a relatively preserved capacity of producing eccentric strength. The …
