Calf muscle-tendon properties and postural balance in old age
GL Onambele, MV Narici… - Journal of applied …, 2006 - journals.physiology.org
We tested the hypothesis that compromised postural balance in older subjects is associated
with changes in calf muscle-tendon physiological and mechanical properties. Trial duration …

Changes in postural muscle dynamics as a function of age
Histologic studies have demonstrated both a decrease in size and loss in number of type II
muscle fibers with increasing age. Although these age-related histologic changes are …

Leg and trunk muscle coordination and postural sway during increasingly difficult standing balance tasks in young and older adults
Ageing impairs body balance and increases older adults' fall risk. Balance training can
improve intrinsic fall risk factors. However, age comparisons of muscle activity responses …

Effect of leg muscle contraction velocity on functional performance in older men and women
Objectives: To explore the relationship between impairment (skeletal muscle strength and
contraction velocity) and function in community‐dwelling older adults. Design: Cross …

Aging, muscle activity, and balance control: physiologic changes associated with balance impairment
Older adults demonstrate increased amounts of postural sway, which may ultimately lead to
falls. The mechanisms contributing to age-related increases in postural sway and falls in the …

Relationship between muscle function, muscle typology and postural performance according to different postural conditions in young and older adults
T Paillard - Frontiers in Physiology, 2017 - frontiersin.org
Although motor output of the postural function clearly influences postural performance in
young and older subjects, no relationship has been formally established between them …

Muscle pre-and coactivity during downward stepping are associated with leg stiffness in aging
T Hortobágyi, P DeVita - Journal of Electromyography and Kinesiology, 2000 - Elsevier
We have previously reported that elderly compared to young women executed downward
stepping with substantially greater leg stiffness. Because antagonist muscle coactivity …

Differences in lower-extremity muscular activation during walking between healthy older and young adults
A Schmitz, A Silder, B Heiderscheit, J Mahoney… - … of electromyography and …, 2009 - Elsevier
Previous studies have identified differences in gait kinetics between healthy older and
young adults. However, the underlying factors that cause these changes are not well …
