Abstract
Purpose
The purpose of this research was to compare the differences in resting blood pressure and heart rate variability (HRV) in spontaneous obesity between obese and non-obese adolescents. This obese (OB, age: 17.1, 0.74 yrs; height: 173.5, 4.94 cm; weight: 103.9, 16.4 kg;% BF: 29.0 ± 5.68; SBP: 119.2 ± 5.9; DBP: 74.6 ± 6.7; ; physical activity level: 36.9 ± 9.48; breathing rate / min: 15.9 ± 2.6) and ten non-obese (NO, age: 16.5, 0.71 yrs; height: 166.7, 5.33 cm; weight: 55.1, 106 kg;% BF: 10.5 ± 5.22; SBP: 100 ± 11.5; DBP: 62.6 ± 6.6; WC: 68.3 ± 6.4; physical activity level: 41.1 ± 14.8; breathing rate / min: 15.9 ± 2.7) healthy male adolescents participated in the study.
Methods
Subjects visited the laboratory science and underwent a 5-minute spontaneous breathing condition. Independent T-Tails with Cohen's D analyses were carried out to establish the variable differences. Pearson's correlation was utilized to determine the relationship of waist circumference to blood pressure and HRV.
Results
Findings revealed that OB participants showed higher systolic pressure (119.2 ± 5.9 mmHg) than NO (100.0 ± 11.5 mmHg) at t (18) = 4.71, d = 3.53, p <0.01. Diastolic blood pressure was also higher in OB (74.6 ± 6.7 mmHg) compared to NO (62.6 ± 6.6 mmHg) at t (18) = 4.08, d = 1.80, p <0.01. No significant differences in HRV between OB and NO were detected. Waist circumference was not associated to any measure. of HRV. There was a significant significant relationship between waist circumference (WC) and systolic blood pressure, r = .796, n = 20, p <0.01. There was also a significant correlation between WC and diastolic blood pressure, r = .691, n = 20, p <0.01.
Conclusion
In conclusion, SBP and DBP were higher in NO than OB. There was no significant difference in HRV between NO and OB. Lastly, WC was positively correlated with SBP and DBP.
