The paper entitled “Assessment of heart rate variability during an endurance mountain trail race by multi-scale entropy analysis“, authored by Montserrat Vallverdú, Aroa Ruiz-Muñoz, Emma Roca, Pere Caminal, Ferran A. Rodríguez, Alfredo Irurtia and Alexandre Perera has been published in Entropy (JCR IF: 1.821).
The study analyzed the heart rate variability (HRV) response to high-intensity exercise during a 35-km mountain trail race to ascertain whether fitness level could influence the autonomic nervous system modulation. Time-domain, frequency-domain, and multi-scale entropy indexes (MSE) were calculated for 11 mountain-trail runners. Many changes were observed, mostly related to exercise load and fatigue. The time-domain, frequency-domain, and MSE indexes were also able to discriminate faster from slower runners, mainly in the more difficult and in the final stages of the race. These findings suggest the use of HRV analysis to study cardiac function mechanisms in endurance sports.
