An inexpensive, fast and reliable estimation of cardiorespiratory fitness
Importance of Cardio Respiratory Fitness
Statement Paper from American Heart Association
“At a minimum, all adults should have CRF estimated each year using a non-exercise algorithm during their annual healthcare examination. Clinicians may consider the use of submaximal exercise tests or field tests as alternatives because these involve individual-specific exercise responses. “
What is Cardio-Respiratory Fitness?
Cardio Respiratory Fitness reflects metabolism and as the name indicates lungs and heart interact by supply of oxygen to tissues and organs and by elimination of carbon dioxide. Maximal oxygen capacity of a person means the maximal oxygen consumption determined until exhaustion and is called VO2max.
Cardio respiratory fitness measured as VO2max correlates not only to fitness but to general health.
Cardiorespiratory fitness (CRF) measured as VO2max may be determined by the Seismofit® System by use of seismocardio graphy. Seismofit® measures vibrations arising from heart beats and transmitted to the chest. Each heart has its own signature relating to opening and closing of valves and the relaxation and contraction of the heart chambers. The system further includes an adhesive patch, a smartphone App and a cloud-based algorithm.
Current methods are too complicated
Ergometer cycling or treadmill running are golden standards for determining VO2max. Various protocols are used i.e. increasing load in given time intervals with measure of oxygen consumption during the test until exhaustion. Submaximal testing protocols not reaching maxial pulse and exhaustion may be used if the test person may be at any health risk with maximal exercise.
The test will when including dressing and preparation take up to 30 minutes.
EASY TO USE
Importance of Cardio Respiratory Fitness (CRF)
VO2 max is a predictor of performance, although its correlation to athletic success in endurance sports is only 30-40%, with other factors such as sustainable lactate threshold, motivation, training, etc. also playing a role. In general, however the higher a VO2 max the more potential for a successful performance in an aerobic endurance event.
Making Cardiorespiratory Fitness measurement a part of everyone’s health check
VentriJect was established as a spin-out from a leading research center in cardiology at Aalborg University in 2018 and is situated in Hellerup near Copenhagen, Denmark.
