Quantification of Athlete’s Heart Condition: A Detrended Fluctuation Analysis
Detrended fluctuation analysis (DFA) technology was used to check the heartbeats of athletes in the Indonesian olympic training center. We report results of time series analysis of heartbeat on subjects who underwent ergometer exercise. The objective of this research was to determine whether DFA could function as a useful computation method for the evaluation of the subject’s quality of cardiovascular system. Since there are no 2 individuals that are identical physiologically, we present case studies but novel findings regarding how wellness of subjects can be evaluated by the electrocardiography. Even from the case studies, we can propose a general conclusion that DFA is a new, useful numerical method for quantifying the degree of wellness through the heartbeat recording.
