1. A method for training control of a test person in sports, comprising the steps of:
- radiating light into body tissue of the test person from outside the body of the test person into the body of the test person at a thigh of the test person which is highly stressed;
measuring light intensity reflected in venous blood in the body tissue of the thigh of the test person;
using an evaluator with an evaluation circuit, deriving a temporally oscillating measurement quantity from the measured light intensity which temporally oscillates corresponding to a heart rate of the test person where each heart rate induced oscillation is substantially the same as the previous oscillation at least during a rest state and an aerobic state of the test person;
determining a plurality of temporally successive minima in a time curve of the measurement quantity at a bottom of each said heart rate induced oscillation;
defining the rest state of the test person when said plurality of temporally successive minima remain substantially constant at a first value, determining the aerobic state for the test person when said plurality of temporally successive minima remain substantially constant at a second value which is less than said first value, and determining an anaerobic state for said test person when said temporally successive minima are not constant but are falling with time so that decreasing values result which are below said second value;
analyzing said plurality of temporally successive minima;
generating via the analysis of the plurality of temporally successive minima a quantity characterizing oxygen saturation in the venous blood as a performance rating from which a current metabolic state of the test person can be read out; and
displaying the generated performance rating.

Abstract
A method and apparatus are used for training adjustment in sports, particularly in running sports, in which light is radiated into the body tissue of a test person by at least one light source, the light intensity reflected in the body tissue is measured via at least one light sensor, a temporally oscillating measurement quantity is derived from the measured light intensity via an evaluator, a minima in the time curve of the measurement quantity are determined, and a performance rating from which the current metabolic state of the test person can be read out is generated via analysis of a plurality of temporally successive minima and displayed.

10. An apparatus for training control of a test person in sports, comprising:
-
at least one light source configured to radiate light into body tissue of the test person from outside the body of the test person into the body of the test person at a thigh of the test person which is highly stressed; at least one light sensor configured to measure light intensity reflected in venous blood in the body tissue of the thigh; an evaluator configured to derive a temporally oscillating measurement quantity from the measured light intensity which temporally oscillates corresponding to a heart rate of the test person where each heart rate induced oscillation is substantially the same as the previous oscillation at least having a rest state and an aerobic state of the test person, to determine a plurality of temporally successive minima in a time curve of the measurement quantity at a bottom of each said heart rate induced oscillation, and via an analysis of the plurality of temporally successive minima, determining a quantity characterizing oxygen saturation in the venous blood as a performance rating of the test person from which a current metabolic state of the test person can be read out; and said evaluator comprising an evaluation circuit which defines the rest state of the test person when said plurality of temporally successive minima remain substantially constant at a first value, determines the aerobic state for the test person when said plurality of temporally successive minima remain substantially constant at a second value which is less than said first value, and determines an anaerobic state for said test person when said temporally successive minima are not constant but are falling with time so that decreasing values result which are below said second value. - View Dependent Claims (11, 12, 13, 14)
