Physical Activity and Its Correlation to Maximal Oxygen Uptake in an Elderly Population (Gen100sub2)

Self Reported Physical Activity vs Objectively Measured Physical Activity and Its Correlation to Maximal Oxygen Uptake in an Elderly Population: an Observational Study

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).

Study Overview

• Status: Completed
• Conditions: Aging

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.

• Study Type: Observational
• Enrollment (Actual): 1237

What is the study measuring?

Primary Outcome Measures

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

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Difference between self reported recall physical activity and activity monitor measured physical activity	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.	Baseline

Other Outcome Measures

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