Effects of Acute Exercise on Blood Pressure and Heart Rate in a Pediatric Population: a Comparative Investigation
Year: 2024
Type: article
Abstract: Pediatric hypertension is one of the main cardiovascular problems today. The aim of this study was to evaluate the hemodynamic effect after an aerobic test in children and adolescents. Methods: The effects of systolic blood pressure (SBP) and diastolic blood pressure (DBP) were analyzed before and after a 6-minute run and walk test (between rest, immediately after, 15 and 30 minutes after the run test) in volunteers with increased blood pressure (n=22) in the experimental group (EG), compared to the control group (n=22) (CG). Anthropometric measurements were taken (weight (kg) and height (m)), body composition (body mass index kg/m2 and % fat) and heart rate variability (HRV). Results: There was a reduction in SBP after 30 minutes of activity in the SG (118.3±10.5 vs 109.2±11.3 mmHg) compared to rest. The CG remained the same (112.2±11.6 vs 112.6±14.0) with no statistical difference (p>0.05). For DBP, there was no significant variation (p>0.05) between the groups or between the time points. When assessing heart rate (HR), there was a significant increase between the SG and CG groups (91.36±11.6 vs 110.9±12.2 and 88.2±17.7 vs 101.7±15.5) bpm). Only BMI and the SDNN, PNN50 and HF indices showed a statistical difference between the two groups (p<0.05). Conclusion: There was a reduction in SBP 30 minutes after the running and/or walking test in the experimental group, demonstrating positive effects after the running and walking test in children and adolescents.
