In order to investigate some characteristics of physical fitness in children, we measured the heart rate of 1069 kindergarten children (aged 4-6years) and 20 adults during treadmill running. After analyzing the data we obtained the following results : heart rate before, during, and after the running tended to diminish with the increase in age of the subjects in both men/boys and women/girls. The relationship of the heart rates before running and the maximum heart rates during in 25m run, standing long jump, and softball throw, showed a significant level of 5-0.1% in both boys/men and girls/women. The heart rates of children before, during and after running were higher than those of adults. The rate of increase in heart rate was higher in adults, while more raped recovery of heart rate was observed in children, when compared to adults.
