Physical Activity, Sleep and Age

Maastricht University Medical Center45 enrolled

Overview

Ageing is associated with a reduction of physical activity, movement efficiency, and quality of sleep. This leads to reduced health and well being in elderly subjects. Exercise training can increase movement efficiency and quality of sleep. Objectives: 1. Laboratory validation test of body acceleration based indexes for movement efficiency and quality of sleep; 2. Cross-sectional analysis to assess relations between these indexes and age; 3. Intervention study to assess the effect of exercise training on daily life movement efficiency and quality of sleep in ageing subjects 45 healthy human volunteers, age 50-83 yr, BMI 20-30 kg/m2 are divided in control or intervention group. Subjects that will have practiced fitness activities in the previous year, as well as pregnant or lactating women, will be excluded.

Inclusion Criteria: * Men and women * Age between 50-85 years * No fitness activity in the previous year, to amplify training effects on movement efficiency and quality of sleep. * Body mass index between 20 and 30 kg/m2, obesity limits the training capacity of subjects. Signed informed consent by the participants Exclusion Criteria: * Age below 50 or above 85 years; * body mass index below 20 kg/m2 or above 30 kg/m2; * neurologic, cardiologic or invalidating orthopaedic disease; * pregnancy or lactation.

Outcomes

Primary Outcomes

Changes in movement efficiency

The primary objective is to identify features of body acceleration to be included in an index to assess daily life movement efficiency. Secondly, the index is related with age to quantify how ageing affects daily life movement efficiency. The third objective is to show the effects of regular physical activity training on this index. The expected improvement of the index would show that exercise delays the age related decrease of movement efficiency.

Time frame: At baseline and after 1 year

Secondary Outcomes

Changes in quality sleep

The primary objective is to identify features of body acceleration to be included in one index to assess quality of sleep in daily life. Secondly, the index is related with age to quantify how ageing affects quality of sleep. The third objective is to show the effects of regular physical activity training on this index. The expected improvement of the index would show that exercise delays the age related decrease of quality of sleep.
