The cognitive complexity of concurrent cognitive-motor tasks reveals age-related deficits in motor performance
Abstract Aging reduces cognitive functions, and such impairments have implications in mental and motor performance. Cognitive function has been recently linked to the risk of falls in older adults. Physical activities have been used to attenuate the declines in cognitive functions and reduce fall in...
