Aerobe und anaerobe Energiebereitstellung als Funktion einer statistischen Verteilung der maximalen oxidativen Leistungsfähigkeit der einzelnen Muskelfaser

Summary

The oxygen uptake during exercise can be conceived as the sum of the oxygen uptake of all involved muscle fibres. Starting from this thesis and under the supposition of a normal distribution of oxidative capacity of the muscle fibre computer calculations are presented for step load and ramp load.

They allow simple explanations for the following:

1. why lactate is produced below a load corresponding to the maximal oxygen uptake

2. why a rise in the aerobic-anaerobic threshold results from an endurance training with persistent maximal oxygen uptake

3. for the “levelling-off-phenomenon„ in oxygen uptake

4. for the different flexures of lactate curves in the graded test depending on endurance performance capacity.
