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. 000153007 536__ $$9info:eu-repo/grantAgreement/ES/DGA-FSE/T39-20R$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/PGC2018-095936-B-I00$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/RTI2018-097723-B-I00$$9info:eu-repo/grantAgreement/ES/UZ/CUD2019-10$$9info:eu-repo/grantAgreement/ES/UZ/UZCUD2019-TEC-01 000153007 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000153007 592__ $$a0.257$$b2020 000153007 593__ $$aComputer Science (miscellaneous)$$c2020 000153007 593__ $$aCardiology and Cardiovascular Medicine$$c2020 000153007 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000153007 700__ $$aDolores Pelaez Coca, María 000153007 700__ $$aSánchez, Carlos 000153007 700__ $$aJuan, Bolea 000153007 700__ $$0(orcid)0000-0002-4746-3139$$aIzquierdo, David 000153007 700__ $$aTeresa Lozano Albalate, María 000153007 700__ $$0(orcid)0000-0001-7285-0715$$aGil, Eduardo$$uUniversidad de Zaragoza 000153007 7102_ $$15007$$2520$$aUniversidad de Zaragoza$$bDpto.
