The aim of the study was to estimate changes in heart rate (HR) values in response to the exercise under isokinetic conditions, with defined protocol using three different angular velocities and 2 minute break. The subjects were divided into two groups. The first group contained 18 males aged between 40 and 50, and the second group contained 20 males who were 20–30 years old. The heart rate was monitored before, during and after the strength moment measurement under isokinetic conditions of extensors and flexors of knee joint. The strength moment was measured with an angular velocity of 180 °/s, 120°/s and 60 °/s. The number of repetitions of extension and flexion of the knee joint was 10 for the angular velocity of 180 °/s, 8 for the angular velocity of 120 °/s and 5 for the angular velocity of 60 °/s. The break between each series of repetitions took 2 minutes. The peak torques for extensors and flexors of both lower extremities were measured. The peak torque and heart rate values increased with a decrease in the preset angular velocity and were lower in the second group. The results were within the norm accepted for submaximal heart rate index in both age groups.
