Gyrocardiography- A New Non-invasive Cardiac Measurement Method to Measure Exercise Capacity and Cardiorespiratory Fitness
The goal of this study is to produce a solution to measure the cardiorespiratory fitness (CRF), which can be used by commercially available smartphones without extra equipment, add-ons and special know-how.
This observational study with follow-up is to test the feasibility of a new non-invasive cardiac measurement method (gyrocardiography, GCG) in detecting hemodynamic parameters to measure exercise capacity and cardiorespiratory fitness in healthy subjects.
The objective is to produce a solution which can be used to measure the exercise capacity and cardiorespiratory fitness (CRF) of the exercisers, keep-fit athletes and professional athletes using hemodynamic parameters such as:
Participants are either athletes or non-athletic persons. The athletes will perform spiroergometry and non-athletic persons ergometry to measure the CRF expressed as VO2max.
Following parameters will be measured during the (spiro)ergometry:
The GCG measurements for acquiring the hemodynamic parameters are performed before and after the (spiro)ergometry using smartphone. During a 1- minute GCG measurement, the smart phone is placed on the chest in the middle of the sternum.
