Abstract
The main problem to monitor heart rate by photoplethysmography during physical exercise is the presence of movement artefacts. We have recorded transmittance photoplethysmogramms in athletes along a maximal exercise test by treadmill ergometer using a new sensory system with multiple near infrared laser diodes. The obtained heart rates agree with those by electrocardiography
