For the evaluation of your fitness it is very important a test methodology safe and reliable.
The Conconi test allows you to estimate the anaerobic threshold thanks to a series of samples during which the associated heartrate will be monitored.
As an alternative to the previous methodology, SportPlusHealth makes available the Mader test. In this case, you will be able to estimate the aerobic and anaerobic thresholds thanks to a series of samples spaced by measures of the amount of lactic acid in the blood.
