In this presentation we can see how we can link external to internal load during training. One of the major problem for injuries is overload during training session, to have the possibility to analyze training load with these two different possibility is, from my point of view a great innovation for athletes' safety. More we study also pitches to create innovation of product on this topic in order to increase also in this area the safety for the player we follow.
