Sažetak

Fifty-three 5.5-year-old children (25 boys and 28 girls) participated in the research that took place during a 45-minute physical education class. Before the class started, every child’s heart rate (HR) in the state of rest had been measured. During the main part of the class, the children participated in relay races, after which the highest values of HR were obtained. On the basis of the results and Karvonen’s formula the intensity of effort, ranging from 50% to 100%, was calculated for groups and for individuals. In the state of rest the HR in boys reached 99.28 beats per minute (bpm) (SD 5.08), and in girls - 98.72 bpm (SD 9.11). The highest HR value in boys was 214.24 bpm (SD 8.88), and in girls 213.71 bpm (SD 8.93). Most of the individual results differ from the results of the group, which proves that the HR is an individual feature, and that the levels of intensity of the effort calculated on the basis of HR should not be generalized.
