摘要：Objectives: 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. Method: This investigation involved 41 children (20 boys and 21 girls), aged between 10 and 11 years (average age=10.78 and standard deviation=0.42). 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. Results: Data analysis was performed through SPSS 22 and significant improvements were obtained in systolic blood pressure and heart rate (Sig p < 0.05). Discussion: In the scientific literature, most studies also find that physical activity significantly improves blood pressure and heart rate in both sexes and at different ages, although some studies do not find significant relationships. Conclusions: The physical activity program implemented in this study may be useful to improve systolic blood pressure and heart rate in 10- and 11-year-old school children.
