Value of the Data •Sport Database may be useful to investigate physiological and pathological adaptations of the cardiorespiratory system to different types of physical exercise. •Sport Database may support the development of automatic algorithms finalized to real-time health monitoring of athletes and preventive identification of subjects at increased risk of sport-related sudden cardiac death. •Sport Database may support clinical testing of the wearable sensor BioHarness 3.0 by Zephyr. •Besides clinicians and biomedical engineers doing research on sport effects on athletes’ health, personal trainers can benefit from these data to optimize training sessions from both health and performance points of view. •Further acquisitions could involve other sports, other cardiovascular signals and/or parameters, data from different biological systems (for example the metabolic system and the motor system), and other acquisition devices. •Additional value of these data consists in their usefulness to evaluate filtering procedures for cardiorespiratory signals, since acquisitions during exercise are affected by high levels of noise.
