“…It has been reported that a decrease in HRV might predict mortality after myocardial infarction (Brateanu, 2015 ;Sen & McGill, 2018). Decreased HRV can be also associated with diabetic neuropathy, cardiac transplantation and sudden cardiac death (Islam, Kim, Lee, & Moon, 2018 ;Lin et al, 2017 ;Sessa et al, 2018).…”

This study aims to investigate how different types of regular physical activity affect cardiac functions in school children. This is a cross-sectional review of 15 children who are not engaged with any regular physical activity (controls) and 60 athletes who swim (n=15), play basketball (n=15), play volleyball (n=15), and play tennis (n=15) regularly. The mean age of the control children was computed as 11.3±1.8 years whereas the mean ages of swimmer children, the children who play basketball, volleyball and tennis regularly were calculated as 10.7±1.5 years, 12.0±1.9 years, 12.6±2.2 years and 10.6±1.4 years respectively. The children who are not engaged with any sports, the children who swim, and the children who play basketball, volleyball, and tennis are statistically similar with respect to age, sex, height, weight, and body mass index (p>0.05 for all). When compared to the controls and other athletes, the swimmer children have significantly higher left ventricle diastolic mass, higher left ventricle posterior wall systolic thickness, lower mitral A wave, higher mitral annular plane systolic excursion, and higher mitral E/A ratio (p=0.006, p=0.035, p=0.030, p=0.025 and p=0.043 respectively). The swimmer children have significantly lower interventricular septum E and A waves and significantly longer left ventricle isovolumic relaxation time than the controls and other athletes (p=0.001, p=0.040 and p=0.004 respectively). When compared with the controls and other athletes, the swimmer children have significantly lower p-wave dispersion and QT dispersion values (p=0.038 and p=0.035 respectively). The swimmer children have significantly higher total power and SDNN values than the controls and other athletes (p=0.046 and p=0.026 respectively). Swimming might contribute to the growth of cardiac muscles and help to improve the cardiac conduction system and enhance parasympathetic innervation of the heart in children.

Fractal correlations and linear analyses of heart rate variability in healthy young people with different levels of physical activity

et al. 2019

Changes in cardiac autonomic regulation, expressed by increased sympathetic activity and decreased heart rate variability, have an important relationship with the onset of lethal cardiac phenomena. Therefore, we aimed to evaluate the cardiac autonomic behaviour in young people according to their level of physical activity. Through the International Physical Activity Questionnaire, 55 healthy young non-smokers with no history of previous diseases and whose parents did not suffer from metabolic syndrome were assessed and divided into groups: sedentary (n=12), insufficiently active (n=16), active (n=14), and very active (n=13). We collected respiratory rate, systolic and diastolic blood pressure at rest, and body mass index. Subjects remained supine at rest, and without mental stress for 15 minutes in a controlled environment. Using a cardiofrequency meter (Polar® RS800CX), data were analysed in the time domain, frequency domain, and detrended fluctuation analysis. For the sedentary group, the mean RR and rMSSD were significantly lower, and the insufficiently active group showed higher means, but significantly only for rMSSD. The insufficiently active group showed in the detrended fluctuation analysis that α2 was significantly lower compared with the sedentary, active, and very active groups. We conclude that young, healthy, sedentary individuals present an increased heart rate and that insufficiently active individuals present a decreased fractal correlation and increased parasympathetic activity.
