Brief summary

This is a substudy of the Generation-100 study (NCT01666340). Self reported physical activity versus objectively measured physical activity and its correlation to maximal oxygen uptake in an elderly Norwegian population (observational study).

Detailed description

Data is collected using activity monitors. This data then compared to self reported physical activity obtained through questionnaires. Questionnaires are based on recall. Overall physical activity will then be correlated to maximal oxygen uptake to see whether people with high activity also have high maximal oxygen uptake.

Design outcomes

Primary

Measure	Time frame	Description
Correlation between maximal oxygen uptake and activity level	baseline	maximal oxygen uptake measured using Metamax on a Treadmill. Activity level assessed using triaxial activity monitors.

Secondary

Measure	Time frame	Description
Difference between self reported recall physical activity and activity monitor measured physical activity	Baseline	self reported Physical Activity is assessed by having participants fill out a questionnaire (developed by HUNT) outlining their Physical Activity (through recall). Physical activity is objectively measured using triaxial accelerometers.

Other

Measure	Time frame	Description
total daily energy expenditure	Baseline	Measured through triaxial accelerometer.
activity energy expenditure	baseline	Measured using triaxial accelerometer
sedentary time	baseline	Measured using triaxial accelerometer
