| Cognitive Performance and Heart Rate Variability: The Influence of Fitness Level |
Luque-Casado A , Zabala M, Morales E, Mateo-March M & Sanabria D | 2013 | PLoS One. 8(2): e56935. | Cross-sectional study; Males, n=28 | Applied use | HRV | The study investigated the relation between cognitive performance and HRV as a function of fitness level. Two groups of participants, a high-fit group and a low-fit group were performing three cognitive tasks (a psychomotor vigilance task, a temporal orienting task, and a duration discrimination task). Firstbeat Bodyguard and Firstbeat athlete were used for HRV analysis. |
