Description of the project

The lactate threshold is a good guideline for the endurance performance and for the control of training. Repeated measurements for individual athletes are of interest, as the threshold is related to types of muscle fibres involved, blood levels of glucose and fatty acids, and the altitude for the exercise. The lactate threshold is generally established by using blood tests. There are also non-invasive techniques to establish the ventilatory threshold. Still there is an interest in finding more cost effective and useful non-invasive methods to estimate the threshold.

In previous pilot studies it has been shown that the lactate threshold is possible to estimate using an electro acoustic sensor system, LACTA, analysing the respiratory air. The system measures the molecular weight of the gas inside the sensor. The aim of the project is to further evaluate the system and to evaluate more applications for the sensor system.
