انا طالع من النت و هذا نص الخبر بالانغليزي و فيه كلام غازيدش عنه

“If there are things we can do [to prevent injuries] we will do them,” he said. “For example, we’ve introduced a GPS system this year for the first time. This is tracking literally from satellites in space, the training movements on the training field of every player.
It gives you a lot of information. It tells you not just how far the players are running and how fast they are running and what levels of intense activity they have in training. It also measures something called ‘the load’ – and this is literally the amount of time a player’s foot is on the ground while he is running.
“You can see if you have a player coming up to a risk of injury in a subsequent game because you can see two things in general: one is that their work-rate comes down in training and secondly their ‘load’ increases. In other words, their foot stays on the ground for longer when they run. When you are feeling good and feeling active you are more on your toes. When you’re not, you’re more on your heels. That can help you to predict when players are in a dangerous situation
