Validation of Ventriject Determined Maximal Oxygen Uptake

Completed

• Conditions: Healthy

• Registration Number: NCT03504306
• Lead Sponsor: University of Copenhagen

Brief Summary

This study aims to validate the use of the Ventriject product to estimate VO2 max, through a non-physically active test using ECG, echoseismography and echosonography.

Detailed Description

this study will be composed of the following tests:

* blood sample for measurement of blood values

* blood pressure measurement to rule out risks affiliated with maximal effort testing

* DXA body composition scanning

* Measurement on ECG, echosonography and echoseismography with accelerometer, microphone and ECG wires

* Measurements with phone (iPhone)

* VO2 max assessment by maximal oxygen uptake testing on a training bike, using online oxygenmeasurement equipment

* Hand-grip strength assessment

Primary Outcome Measures

Name	Time	Method
Comparing how well the Ventriject software can estimate VO2 max	4 months data collection, although cross sectional	VO2 max tested on bike with online software Ventriject will estimate VO2max based on ECG, echoseismography and echosonography obtained at rest

Secondary Outcome Measures

Name	Time	Method
comparing how well the measurements from the mobile phone test compare to the same measurements with accelerometer and echosonography	4 months data collection, although cross sectional	comparison of ECG, echoseismography and echosonography obtained at rest to a measurement of movement (caused by heart contraction) by mobile phone, also at rest
