Changes in postural muscle dynamics as a function of age

RP Huang, CT Rubin, KJ McLeod - Journals of Gerontology …, 1999 - academic.oup.com

Leg and trunk muscle coordination and postural sway during increasingly difficult standing balance tasks in young and older adults

L Donath, E Kurz, R Roth, L Zahner, O Faude - Maturitas, 2016 - Elsevier
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 …

Aging, muscle activity, and balance control: physiologic changes associated with balance impairment

CA Laughton, M Slavin, K Katdare, L Nolan, JF Bean… - Gait & posture, 2003 - Elsevier
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 …

[HTML][HTML] 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
