摘要：This paper focuses on studying the effects of a vigorous-intensity physical activity program on the blood pressure (BP) and heart rate (HR) of a group of school children. This investigation involved 33 children (14 boys and 19 girls), aged between 6 and 7 years (average age=6,45 and standard deviation=0.5). The variables considered were: blood pressure (systolic and diastolic) and resting heart rate. Blood pressure and heart rate were measured by arm sphygmomanometer Visomat Comfort 20/40. The procedure was as follows: pre-test, intervention and post-test. The intervention consisted of 3 days per week of high-intensity physical activity, 15 minutes per day, during 12 weeks. Data analysis was performed through SPSS 20 and significant improvements were obtained in systolic blood pressure and heart rate (Sig p < 0.05). The physical activity program implemented in this study may be useful to improve systolic blood pressure and heart rate in 6- and 7-year-old school children.
