Th e purpose of this study was to evaluate the validity and reliability of the accelerometer S3+. Th is is an optional part of the new model heart rate monitor Polar RX5. Four endurance athletes completed the on treadmill (0% slope) graded exercise test with an initial speed of 5 kmh-1 with the increase of 0.5 kmh-1 every 200 meters. Th e test was conducted to rejection. From 8 kmh-1 walking was directive turned to running locomotion. Test was repeated under similar conditions to determine the degree of measurement stability. Th e study results showed that accuracy of running measurement is within the error provided by the manufacturer (3%). For walking, the error rate is higher (10%). Reliability of measurements was observed in all parameters is high (r> 0, 80) except to the overall stability of the measurement of walking distance (r = 0.53).
