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. info:eu-repo/grantAgreement/ES/MINECO/TIN2014-5356-R info:eu-repo/grantAgreement/ES/FIS/PI12-00514 info:eu-repo/grantAgreement/ES/DGA/Grupo Consolidado BSICoS info:eu-repo/grantAgreement/ES/UZ/UZ2014-TEC-01 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0001-8742-0072 Lázaro, Jesús Universidad de Zaragoza Hernando, Alberto Arza, Adriana Garzon, Jorge Mario (orcid)0000-0001-7285-0715 Gil, Eduardo Universidad de Zaragoza (orcid)0000-0003-3434-9254 Laguna, Pablo Universidad de Zaragoza Aguiló, Jordi (orcid)0000-0003-1272-0550 Bailón, Raquel Universidad de Zaragoza 5007 520 Universidad de Zaragoza Dpto.
