To do that, electrocardiogram signals from 6 subjects were recorded in a reservoir immersion. Two different stages were analyzed: baseline stage, where subjects remained seated outside the water; and immersion stage, where subjects performed physical activity in a non-controlled environment. The smoothed pseudo Wigner-Ville distribution was used for the timefrequency analysis. Results show a statistically significant increase of the mean heart rate and a significant decrease in the root mean square of the successive normal beats during the immersion stage. However, frequencydomain parameters did not show any significant difference between stages. Whereas time-domain parameters reflect a sympathetic activation during the immersion, caused by the predominance of the physical activity and the stress of the challenging environment, frequency-domain parameters are not able to capture it. Further studies are needed to draw more robust conclusions by increasing the number of subjects and exploring alternative methods to compute the Autonomic Nervous System frequency content. info:eu-repo/grantAgreement/ES/DGA-FSE/T39-20R info:eu-repo/grantAgreement/ES/MINECO-FEDER/PGC2018-095936-B-I00 info:eu-repo/grantAgreement/ES/MINECO-FEDER/RTI2018-097723-B-I00 info:eu-repo/grantAgreement/ES/UZ/CUD2019-10 info:eu-repo/grantAgreement/ES/UZ/UZCUD2019-TEC-01 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 0.257 2020 Computer Science (miscellaneous) 2020 Cardiology and Cardiovascular Medicine 2020 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Dolores Pelaez Coca, María Sánchez, Carlos Juan, Bolea Izquierdo, David (orcid)0000-0002-4746-3139 Teresa Lozano Albalate, María Gil, Eduardo Universidad de Zaragoza (orcid)0000-0001-7285-0715 5007 520 Universidad de Zaragoza Dpto.
