The ONYX PRO gives you the opportunity to
enter your lactate values to control your training
in a very precise manner via your individual
anaerobic threshold IAT. The anaerobic
threshold is determined by measuring lactate:
several blood samples are taken from the
ear in a stepped interval test.
Information on IAT
The anaerobic threshold is very important for
training efficiency as important performance
parameters can be determined with reference
to this value (% above and below IAT).
Depending on the level of load the body takes
the energy required from various sources. We
can differentiate between three situations
relating to the anaerobic threshold:
k
For loads below the anaerobic threshold the
energy is primarily provided by converting
oxygen, i.e. “aerobically”. It is possible to
maintain endurance for a very long time,
e.g. for a marathon race.
k
Loads on the anaerobic threshold are
relatively high to be maintained over a long
period of time (the glycogen reserves are
virtually exhausted after 60 to 90 minutes
depending on the training stated at high
intensity).
k
Loads above the anaerobic threshold are
handled primarily by providing energy
“anaerobically”. The lactate increases and
this can adversely affect performance so
that it is only possible to maintain the
performance for a short period of time
(a few minutes).
Note:
Fitness studios and sports medics
carry out lactate tests.
