High-intensity training such as long-distance running has reduced the motivation of preschool children. Soccer is characterized by a significant amount of high-intensity exercise performed during a game and child-friendly sports. Therefore, the present study investigated the effects of soccer at a frequency of once a week on heart rate (HR) response the small-sided soccer games in preschool children. Twenty preschool boys (soccer group, n=10; sports group other than soccer, n=10) participated in the study. Data were collected from the small-sided soccer games. HR and coefficient of variation of RR interval (CVRR) was recorded using short-range telemetry HR monitor systems. The activity profiles of subjects were assessed using Global Position System technology. No significant differences were observed in the mean values of total distance covered or HR during the small-sided soccer games between the soccer group and multi-sport group. During the recovery period, the mean values of HR were significantly lower and CVRR were significantly higher in the soccer group than in the multi-sport group. In conclusions, the present results indicate that playing small-sided soccer only once a week in preschool children induces the faster recovery of HR by the intermediary of cardiac parasympathetic nerve after high-intensity exercise.
