Resumen: ‘ithlete Heart Rate Variability’ app has been scientifically designed for monitoring the body heart rate and give information about when to train and when to rest. The process of training is stressing and has an impact on health. This app offers a very quick and healthy biofeedback of how stressed, recovered and ready for training your body is. It can also avoid injuries by giving users information related to optimising the effectiveness of their workout sequence. The app allows users to register their heart rate variability (HRV) and the time gap between the heartbeats when the body is resting, in order to offer users a more precise picture of their overall health and fitness status (figure 1). HRV, the beat-to-beat variation in either heart rate or the duration of the R-R interval, has become an increasing important clinical diagnostic tool. For example, Lombardi and Stein1 review the relationship between HRV and heart rate turbulence, while Huikuri and Stein2 evaluate HRV as a tool for risk assessment in patients recovering from myocardial infarction.
