Definitions

  • the invention relates to a method and a device for determining the current physical performance of people directly during the training, in which the heart rate is determined continuously, and in which the anaerobic threshold is determined from the determined heart rate and the speed of movement of the person, which Efficiency of the person printed out
  • the measurement of the speed of movement of the person is carried out with a radar device carried by the person
  • a miniature radar speed measuring device which is worn directly on the body and detects the current speed of a person traveling by means of detection and evaluation of the Doppler effect is known from US Pat. No. 4,757,714
  • a mobile, portable body measuring device for the heart rate is known, inter alia, from US Pat. No. 4,566,461.
  • the heartbeat is detected by means of a chest belt and transmitted by radio to a device attached to the wrist
  • the anaerobic threshold is decisive for assessing the endurance performance of an athlete.To determine this threshold, the so-called heart rate deflection point is determined in a heart rate diagram, from which the heart rate can no longer increase linearly with increasing load, e.g. with increasing running speed, the body becomes Loaded up to this point, the oxygen absorbed through the lungs and transported through the blood to the muscles is sufficient to break down the lactate produced during energy conversion to the same extent as it is produced.This is also referred to as sufficient aerobic energy supply, if the Labor intensity is not increased, so there is a lactate balance.
  • the anaerobic threshold indicates the maximum speed at which the load can be sustained over a longer period of time. If the speed is increased above the anaerobic threshold, then k there is an increase in lactate that can no longer be completely broken down
  • the Conconi test is a very simple, non-invasive method for determining the anaerobic threshold.
  • a heart rate-speed diagram is created. The athlete is moving on a closed track Starting at 8 to 12 km / h, he must increase his speed by 0.5 km / h every 200 meters. The heart rate is recorded throughout the test. The test is finished when the athlete can no longer keep to the target speed.
  • the speed specification is either a time table or, in more modern tests, a loudspeaker that emits a signal tone every 20 meters according to the speed that he runs past a hat at every beep
  • the object of the present invention is therefore to provide a method and a device for detecting a current anaerobic threshold, which is independent of location and does not require additional inpatient facilities, as well as without medical assistance.
  • the method according to the invention and the device are intended to enable the athlete , completely independent and on their own, to receive the desired information about their performance during training
  • the device according to the invention consists of a miniature radar speed measuring device for determining the distance covered and the current speed, a heart rate measuring device for determining the current heart rate and a computer unit which detects the values from the signals of the radar device and the heart rate monitor and from them the desired values calculated, all components are combined in a portable device on the body of the athlete
  • This facility independently registers the following data
  • these data can also be used to determine the current output (in watts) and the daily energy consumption (in kJ or kcal)
  • a current threshold value determination can be carried out, the athlete's running speed being permanently controlled via the display device of the device according to the invention. He is completely independent of the location of the determination of the threshold value and can make this determination Carry out completely independently and without external help or auxiliary devices As soon as the anaerobic threshold has been exceeded, the device ends the test and informs the athlete of its speed and heart rate at the anaerobic threshold. The corresponding speed is used to assess the performance and the corresponding heart rate as a guide for future training planning
  • the device is able to measure the gradient of the heart rate curve via the speed as an index for the current state of regeneration Depicting the resilience of the athlete
  • the gradient of the heart rate curve changes depending on the training design of the past days or weeks. If an athlete approaches "overtraining, the maximum heart rate drops, the resting frequency increases. As a result, the regression line flattens out. Conversely, the regression line becomes steeper again after a period less training
  • This regeneration or resilience index can also be calculated without exceeding the anaerobic threshold.
  • the position of the regression line (three to five heart rate points are determined at low speed) can also be used to calculate a possible change in the position of the anaerobic threshold compared to the last test, without it to have to go through
  • the anaerobic threshold can also be calculated with an acceptable accuracy based on these regression lines, without the person ever having to the stress that must go through the anaerobic threshold. This is particularly advantageous in the elderly or sick people
  • the drop in performance compared to the start of the training can also be calculated and presented as protection against overload
  • the device according to the invention and the method according to the invention have a very wide field of application. They are for example for competitive athletes who are in their
  • Suitable for moving sports essentially without aids are sports such as running, skiing, cross-country skiing, athletics, tennis, soccer, ice hockey, ice skating
  • Microwave module 1 a signal of a certain frequency directed obliquely to the walking floor. According to the Doppler effect, those reflected on the floor experience Microwaves a frequency shift linear to the running speed
  • the Doppler frequency is separated out in the microwave module 1 by means of a mixer or filter via the collected reflection signal.
  • the doubling frequency is amplified and filtered in a signal processing module 2.
  • the corner frequencies of the filters can be freely set by the user via the restriction of the frequency range, the Doppler signal is adjusted to a preferred speed range.
  • the athlete for example, runs along a street, he can prevent the radar device from also detecting the cars passing by, thus falsifying measurements or falsifying the distance covered, in this case, for example, he chooses 25 km / h as the upper speed limit, so the sources of interference on the road are eliminated.
  • the Doppler signal is converted into a square wave signal via a Schmitt trigger and fed to the microcontroller 3. Then the formula is used
  • f d ((2v 0 xf 0 ) / c) x cos ⁇
  • f d Doppler frequency
  • c speed of light
  • f 0 transmission frequency
  • the current speed is determined The distance traveled can be determined from the number of square-wave pulses.
  • the heart rate pulses are received and microcontroller 3 is fed in to calculate the heart rate. The results of the calculations in microcontroller 3 can optionally be shown on display 5.

Abstract

L'invention concerne un procédé et un dispositif pour la détermination de la puissance physique du moment de personnes. Selon l'invention, la fréquence cardiaque est déterminée en continu, et à partir de la fréquence cardiaque déterminée et de la vitesse de déplacement de la personne est calculée une grandeur qui exprime la puissance de la personne. La vitesse de déplacement est mesurée par un appareil radar (1) porté par la personne elle-même, par évaluation d'un signal Doppler, et elle est exploitée dans une unité de calcul (3) avec les données de la fréquence cardiaque. Les mesures peuvent être réalisées à n'importe quel endroit. Le sportif est ainsi complètement indépendant d'une aide extérieure ou de dispositifs auxiliaires.
