Abstract

In this study, we use the complex correlation method derived from the Poincare map along with standard SD1 and SD2 parameters to obtain a better understanding of the relationship between optimal autonomic control of the heart rate and the correlation to fitness and exercise. Fifty participants were randomized into a moderate volume (n=19), high-volume (n=15) and control group (n=16). The duration of the signal is divided into Day (9am-6pm), Night (12am-6am) and 24h groups. Standard Poincare based parameters of heart rate variability SD1, SD2, SD1/SD2 and complex correlation measure (CCM) was calculated for each subject and duration. CCM indicated that there was a greater change associated with moderate volume exercise (median ± iqr 19.96 ± 29.62 vs 14.76 ± 23.14) compared to high volume exercise during the Day with both being significantly different to control (p<;0.05). We conclude that autonomic balance and heart rate variability affects day time function more so than night time function, as metabolic and physiological processes slow down during the night.
