About this study

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

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • healthy adults between 18 and 45 years of age

Exclusion criteria

  • current or previous cardiovascular disease
  • chronic use of medicine
  • pregnancy
  • illnesses which prohibits the testing of maximal oxygen uptake

Treatment and study plan

Ventriject validation

Other

comparing measurements from echocardiography, echoseismography to measurements of maximal oxygen uptake

Primary outcomes

  1. Comparing how well the Ventriject software can estimate VO2 max

    Time frame: 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 outcomes

  1. comparing how well the measurements from the mobile phone test compare to the same measurements with accelerometer and echosonography

    Time frame: 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
