Rugby players are physical monsters, but not to the point of possessing a muscle unknown to ordinary mortals, between the shoulder blades. However, it is quite easy to notice this protuberance in the upper back of athletes during this Rugby World Cup. This little bump is an electronic box and its protective case, slipped under the players’ jersey in a pocket provided for this purpose or in a sort of harness worn under the athletes’ shirt. This box is positioned above the players’ numbers and therefore does not escape the attentive eye of the public.

The electronic device contains a GPS sensor and other measuring tools. It records performance data, such as the speed and accelerations of rugby players. This data can be collected directly by the technical staff and analysts of the different selections and clubs. They are also used between matches and training, in order to present reports to players, to identify their strengths or areas for improvement.

The trainers thus know the distance covered by their foals. They also collect data regarding their physical state, such as heart rate. Practical when it comes to choosing an element to replace during the game.

The machine, easily spotted, is it not annoying or even dangerous for athletes under the threat of muscular tackle, never far from spreading out on the lawns. “It’s not at all embarrassing,” promised Emilien Gailleton, reservist of the XV of France, to the Republic of the Pyrenees. Sometimes when you’re on your back you can feel it, but either way, you’re in the game. »

The sensor weighs around 70 grams and is placed in a rather clever way. With their muscular backs and trapezius muscles, rugby players are rather protected when they fall to the ground.
