Functional Impairments and Exercise in Older Adults With Low Physical Function,

Not Applicable

Completed

• Conditions: Functionally Impaired Elderly; Aging
• Interventions: Other: Active life-style intervention

• Registration Number: NCT02051725
• Lead Sponsor: University of Southern Denmark

Brief Summary

* Aging is associated with a progressive and generalized deterioration of physiologic systems and greater incidence of chronic conditions, which ultimately translates into functional impairment, disability and dependency.

* Physical activity and exercise have been recognized as key pillars for the management of chronic diseases in support of medical treatment, and essential to increase physiologic function, but there is only limited evidence indicating increased physical function, following exercise interventions. One of the greatest challenges in the science of aging and exercise is to understand whether and to which extent exercise and active life-style may postpone the onset of disability and/or reverse physical impairments.

* Maintenance/improvements of physical function and mobility should be considered as primary targets for independent living, active engagement in societal challenges, and, more in general, when promoting "active ageing".

* The aim of this study is to collect preliminary data to identify the feasibility and sustainability of an "active life-style intervention" in older adults with reduced mobility receiving a preventive home visit from the public health care authority.

* This study will represent the base for a larger phase III parallel group study implemented in the public health care setting, with the specific aim of improving physical function and delay the onset of functional impairment in older adults.

Arm && Interventions

Group	Intervention	Description
Active life-style intervention	Active life-style intervention	The "active life-style intervention" is designed as 12-week structured and progressive heavy-resistance power training combined with recommended everyday physical activity.

Primary Outcome Measures

Name	Time	Method
Changes in leg press muscle power	Changes in muscle power from baseline to 12-week follow up	Muscle power will be assessed on the dominant leg with the Notthingham power rig and expressed as Watt/kg. Subjects are sitting with

Physical activity, sedentary behaviour and sleep quality (objectively assessed by accelerometry)	Changes from baseline to 12-week follow up
Cognitive function (Mini Mental State Examination and Digit Symbol Substitution Test)	Changes from baseline to 12-week follow up
Self-report Health-related measures including quality of life, pain, depression, sleep quality, fatigue, activities of daily living, anxiety.	Changes from baseline to 12-week follow up
Body composition including muscle, fat and bone quantity and quality	Changes from baseline to 12-week follow up
Neuromuscular function including strength, power, explosive force, postural control, motor/sensor nerve function	Changes from baseline to 12-week follow up
Selected blood biomarkers related to physical, muscle-skeletal and cognitive function (e.g. C reactive protein, insulin like growth factor, IL-6, BDNF)	Changes from baseline to 12-week follow up
Physical function including short and long distance walking speed, stair climbing, Short Physical Performance Battery Test	Changes from baseline to 12-week follow up
