The invention relates to a method for determining the stress capacity of a person
taking into consideration the individual anaerobic threshold by measuring lactate
concentrations in relation to physical effort. To make it possible to deduce from
the changes in lactate concentration other performance data characteristic of the
person tested, the invention provides for the following process steps: measurement
of time-dependent lactate concentration changes above the individual anaerobic
threshold; adjustment of the measurement cure, in which lactate concentration is
recorded in relation to time, to the measurement values obtained in this way; determination
of a first rise in the measurement curve at a time tIAT which corresponds
to the individual anaerobic threshold: determination of at least one other rise
in the measurement curve at a time tx where txtIAT
and subtraction of the second rise from the first rise to determine a difference A.
