A total of 80 healthy volunteers subjected to a standard stress protocol have been analyzed. Some features derived from the WCB, such as the frequencies at which the maximum peak is located, the distribution of the dominant peaks and the phase entropy have shown statistical significant differences between stress and relax stages. A support vector machine classifier based on these features discriminates stress stages from relax ones with an accuracy ranging from 68 to 89%, suggesting that the interactions between respiration and HRV are altered during stress and may be used to assess it. 000063112 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/TIN2014-5356-R$$9info:eu-repo/grantAgreement/ES/FIS/PI12-00514$$9info:eu-repo/grantAgreement/ES/DGA/Grupo Consolidado BSICoS$$9info:eu-repo/grantAgreement/ES/UZ/UZ2014-TEC-01 000063112 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000063112 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000063112 700__ $$0(orcid)0000-0001-8742-0072$$aLázaro, Jesús$$uUniversidad de Zaragoza 000063112 700__ $$aHernando, Alberto 000063112 700__ $$aArza, Adriana 000063112 700__ $$aGarzon, Jorge Mario 000063112 700__ $$0(orcid)0000-0001-7285-0715$$aGil, Eduardo$$uUniversidad de Zaragoza 000063112 700__ $$0(orcid)0000-0003-3434-9254$$aLaguna, Pablo$$uUniversidad de Zaragoza 000063112 700__ $$aAguiló, Jordi 000063112 700__ $$0(orcid)0000-0003-1272-0550$$aBailón, Raquel$$uUniversidad de Zaragoza 000063112 7102_ $$15007$$2520$$aUniversidad de Zaragoza$$bDpto.
