The aim of this study was to propose a way of testing the maximum HR in the pool with counter current (flume). To obtain relevant data, we modified the methodology used for testing maximum HR on land.
A sample of probands was chosen from students and teachers of Faculty of Physical Education and Sport of Charles University who are former or still active swimmers. A sporttester was used to detect a heart rate.
Data processing was made by Polar Precision Performance program. After completing the test, we checked the collection of blood lactate.
Each proband warmed up on his individual submaximal speed which we determined using the CSS test. The analysis results show that four of the six probands reached maximum values of HR, which was higher than the values obtained by theoretical calculation of max HR.
Lactate levels ranged from 7.7 to 13.4 mmol/l.
