Universidad de Zaragoza (orcid)0000-0001-6025-5070 Validity of the polar h7 heart rate sensor for heart rate variability analysis during exercise in different age, body composition and fitness level groups 2021 Access copy available to the general public Unrestricted This work aims to validate the Polar H7 heart rate (HR) sensor for heart rate variability (HRV) analysis at rest and during various exercise intensities in a cohort of male volunteers with different age, body composition and fitness level. Cluster analysis was carried out to evaluate how these phenotypic characteristics influenced HR and HRV measurements. For this purpose, sixty-seven volunteers performed a test consisting of the following consecutive segments: sitting rest, three submaximal exercise intensities in cycle-ergometer and sitting recovery. The agreement between HRV indices derived from Polar H7 and a simultaneous electrocardiogram (ECG) was assessed using concordance correlation coefficient (CCC). The percentage of subjects not reaching excellent agreement (CCC > 0.90) was higher for high-frequency power (PHF) than for low-frequency power (PLF) of HRV and increased with exercise intensity. A cluster of unfit and not young volunteers with high trunk fat percentage showed the highest error in HRV indices. This study indicates that Polar H7 and ECG were interchangeable at rest. During exercise, HR and PLF showed excellent agreement between devices. However, during the highest exercise intensity, CCC for PHF was lower than 0.90 in as many as 60% of the volunteers. During recovery, HR but not HRV measurements were accurate. As a conclusion, phenotypic differences between subjects can represent one of the causes for disagreement between HR sensors and ECG devices, which should be considered specifically when using Polar H7 and, generally, in the validation of any HR sensor for HRV analysis. info:eu-repo/grantAgreement/ES/DGA-FEDER/Construyendo Europa desde Aragón info:eu-repo/grantAgreement/ES/DGA-FSE/LMP124-18 info:eu-repo/grantAgreement/ES/DGA-FSE/LMP24-18 info:eu-repo/grantAgreement/ES/DGA-FSE/LMP44-18 info:eu-repo/grantAgreement/ES/DGA-FSE/T39-20R-BSICoS group info:eu-repo/grantAgreement/EUR/ERC-2014-StG-638284 info:eu-repo/grantAgreement/ES/MECD/FPU16-05879 info:eu-repo/grantAgreement/ES/MICINN-FEDER/PID2019-105674RB-I00 info:eu-repo/grantAgreement/ES/MINECO-FEDER/RTI2018-097723-B-I00 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.847 2021 CHEMISTRY, ANALYTICAL 29 / 87 = 0.333 2021 Q2 T2 INSTRUMENTS & INSTRUMENTATION 19 / 64 = 0.297 2021 Q2 T1 ENGINEERING, ELECTRICAL & ELECTRONIC 95 / 277 = 0.343 2021 Q2 T2 0.803 2021 Analytical Chemistry 2021 Q1 Biochemistry 2021 Q1 Instrumentation 2021 Q1 Information Systems 2021 Q1 Electrical and Electronic Engineering 2021 Q1 6.4 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Hernando, D.
