Although motor output of the postural function clearly influences postural performance in
young and older subjects, no relationship has been formally established between them …

The purpose of this study was to clarify the difference in muscle coactivation during postural
control between older and young adults and to identify the characteristics of postural control …

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 …

Background The human foot has competent mechanisms for supporting weight and
adapting movement to various surfaces; in particular, the toe flexor muscles aid in …

BACKGROUND: The purpose of this study was to investigate the effects of trunk extensor
muscles fatigue on undisturbed postural control in young healthy adults. METHODS: Fifteen …

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 …

Background. Deficits in balance and muscle function are important risk factors for falls in
older adults. Aging is associated with significant declines in muscle size and density, but …

The aim of this study was to assess the relative torque (a percentage of the maximal capacity
of torque production) at the ankle joint in young and elderly adults during different postural …

Background: muscle functions to generate force-producing movement and also has a role in
proprioception. If ageing compromises these sensorimotor functions of muscle, the ability of …

Muscle fatigue can influence the various mechanisms that regulate balance. Few studies
have investigated the effects of trunk extensor muscle fatigue on postural control. The …
