Problems solved by technology

[0007] While wrist measurement technology has indeed been developed, it may not be possible to reliably measure heart rate from the wrist in the near future, and it may never be possible to reliably measure heart rate from the back of the wrist—at least during exercise when using a standalone device carried by the athlete. Wrist PC, or other similar devices

Embodiment Construction

[0026] Each heartbeat causes flow in a blood vessel and in turn causes a small bump that moves in the direction of the blood vessel, which in image 3 is indicated by reference numeral 32 . Based on the plethysmograph measurements, it was learned that the temporary dilation of blood vessels is not only a result of the heartbeat but also accompanied by respiration in real time. Thus, breathing periodically changes the pressure in the circulatory system. This is because when inhaling, and the resulting expansion of the chest muscles, the pressure in the blood vessels decreases, and the opposite happens when exhaling. The "pump" produced by breathing thus produces a change in pressure which is well transmitted into the fluid, blood in this example. In a healthy person, the pulsation rate is many times greater than the respiration rate. Respiration thus appears as a lower frequency modulation in the blood flow, ie as a change in the cyclic height of the pulse. this is in Fig...

Abstract

The invention relates both to a method and wristop device(20) for monitoring physical exercise. The wristop device 20 comprises a central unit, in which there is a display face 25 and to which a wristband 23 is, or can be, attached, sensor means for collecting a hemodynamic signal from the wrist 21, and a data-processing unit 26 functionally connected to the sensor means, for deriving at least one physiological parameter from the hemodynamic signal. The data-processing unit 26 of the wristop device is arranged to derive from the hemodynamic signal at least one physiological parameter depicting respiration, and further, on the basis of this, to calculate at least one training-effect parameter depending on the person and the exercise. With the aid of the invention, it is possible to eliminate the use of pulse bands in monitoring the training effect of exercise.

Description

technical field [0001] The present invention relates to methods and devices capable of monitoring the movement of a person during exercise, in particular the present invention relates to wrist-top devices. Background technique [0002] Establishing heart rate measurement directly from the wrist has been a longstanding goal in the heart rate monitoring sector. Many methods have been developed to detect heart rate, the most important of which are based on the use of EMFi (Electromechanical Films) to capacitively "listen" to the pulse, the monitoring of changes in the impedance or inductance (bioimpedance / bioinductance) of the blood caused by the pulse and mechanical detection of the pulse. The pulse can be detected using pulse echo by means of ultrasound and light reflection, scattering or absorption in the infrared range. In addition, acoustic monitoring of the pulse has also been attempted. [0003] A disadvantage of the known methods and devices is the poor signal qualit...
