Results were calculated with a generalized linear model using a normal probability distribution and identity link function. BMI, body mass index; HR, heart-rate; RMSSD, root mean square of successive differences; PEP, pre-ejection period; SampEn, sample entropy; DFA, detrended fluctuation analysis;
