- AIM: To evaluate correlations between physical activity, VO2PEAK and body fat versus autonomic function in children.METHODS: Children (n = 98) between 10 and 12 years underwent a maximal exercise test (VO2PEAK) and dual-energy X-ray absorptiometry measured body fat. General physical activity, moderate to vigorous physical activity and vigorous physical activity were assessed by accelerometers. Deep breath test with E/I-ratio calculation and a head-up tilt test were performed. The sum of z-scores represented an index score for autonomic function profile and included E/I-ratio plus difference in blood pressure and heart rate between supine and tilted position. Correlation analyses were performed between physical activity parameters, body fat and VO2PEAK versus autonomic function profile.RESULTS: No significant correlations were found between autonomic function profile and physical activity or body fat (p > 0.05). VO2PEAK was correlated with autonomic function profile in boys (r = 0.30, p < 0.05), but not in girls (r = 0.04, NS). One girl and eight boys terminated head-up tilt test prematurely due to intolerance. Minutes of vigorous physical activity per day was lower in these boys compared with those (n = 48) who completed the head-up tilt test (5.1 ± 3.3 vs. 10.4 ± 6.6, p < 0.05).CONCLUSION: Physical activity or body fat was not associated with autonomic function profile. VO2PEAK correlated to autonomic function profile in boys.
