The autonomic nervous system (ANS) is the control mechanism of heart rate variability (HRV). Assessing HRV can lead to prominent information about this control system, taking into account the two control sympathetic and vagal branches. HRV can be evaluated by analyzing RR time series (consecutive heart beats) from linear methods in time and frequency domain in order to extract HRV indexes. Moreover, it is known that heart rate dynamics is not strictly linear, this is the reason that analyzing HRV dynamics by non-linear techniques can provide additional and essential information to the ANS. This project focuses on the quantification of several linear and non-linear metrics from athletes’ RR recordings obtained during a trail and rest conditions, concretely, the days before and after this effort under supine and orthostatic positions.
