An inexpensive, fast and reliable estimation of cardiorespiratory fitness
Cardiorespiratory fitness (CRF) measured as VO2-max may be determined by the Seismofit® System. Seismofit® measures the vibrations that arises from the beating heart and transmits to the chest wall. The method of measuring these vibrations is referred to as Seismocardiography.
Each heart has its own signature relating to opening and closing of valves and the contraction and relaxation of the heart chambers. The Seismofit® System measures these vibrations with the Seismofit® device. The signal is transferred to a smartphone App and a cloud-based algorithm analyses the signal. The estimated VO2-max is returned to the smartphone App.
Importance of Cardio Respiratory Fitness
In resent years, the importance of measuring, estimating and monitoring cardio respiratory fitness (CRF) has been increasing. CRF is a good indicator for overall health and accordingly to a statement paper from the American Heart Association, it is potentially a stronger predictor of mortality, compared to commonly used risk factors.
From the 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 VO2-max.
Cardio respiratory fitness measured as VO2-max correlates not only to fitness but to general health.
