The present invention refers to a micro-controlled non-invasive device for measuring the lactic acid in high-performance athletes, said device measuring the pulse through a mechanical effort and the speed of the athlete using an accelerometer, then a normalization being performed so as to obtain the deflexion point where the pulse and speed curves are separated, also using various models for assessing the generation of lactate in the athlete. In addition, the device measures influential factors such as temperature, altitude, relative humidity and hour of the day, these factors being considered in the lactate evaluation. After the processing, the device may display the generated lactate. The system also uses a pulse frequency demodulator (IPFD) and an accelerometer based on MEMS for measuring pulse and speed respectively. The system is implemented with an interface of the bracelet type which is worn in the wrist of the athlete, or using a sensor for capturing the effort exerted by puls e signals and which may detect the cadence (movement) of the athlete. Finally, the device may display the lactate to the user, also transmitting the information to a training site or a test control central in a wireless form.
