SENSOR, DISPOSITIVO, SISTEMA Y METODO NO INVASIVO PARA DETERMINAR PARAMETROS DE ENTRENAMIENTO DURANTE LA REALIZACION DE UN EJERCICIO FISICO

A non-invasive, ring-shaped sensor (1) for determining blood oxygen saturation and heart rate of a person performing a physical exercise comprises a signal transmitter that transmits signals through the tissue and the arterial blood volume in the finger of the person, a receiver for receiving the transmitted signals and a first communication unit (4) that sends these signals wirelessly to a second communication unit (9) of a remote electronic device (7). In the device (7) the maximum lactate concentration, in the case of the performance of a progressive and intense exercise, and the training heart rate range are determined on the basis of the oxygen desaturation value in the arterial blood volume. The invention also relates to a system that comprises a sensor (1) and a device (7), as well as to the method for determining working zones using this system.
