What Is That Bump at the Back of the England Jersey?

If you've ever watched an England rugby match, you might have noticed a peculiar bump on the back of the player's jerseys. This isn't a design flaw or a random quirk; it's a housing for high-tech sports equipment. 

Rugby players often wear sports bras with pockets holding devices like GPS trackers and heart monitors. These gadgets create a noticeable bulge on the back of the jersey.

This technology has become a staple in modern rugby. According to Rugby World, these devices are crucial for monitoring players' performance and health during games. They provide vital data that coaches and medical teams use to enhance training and ensure player safety. More on this below.

GPS Tracker

The GPS tracker is a crucial component housed in the bump of the England rugby shirt. This sophisticated device tracks players' positions on the field, offering insights into their movements, speed, and overall physical exertion during a game. 

It's a valuable tool for coaches to analyse strategies and player stamina.

Accelerometer, Gyroscope, And Magnetometer

Apart from the GPS tracker, the sports bras worn by rugby players also contain an accelerometer, gyroscope, and magnetometer. These instruments measure acceleration, orientation, and magnetic fields, offering a comprehensive view of a player's physical dynamics in the game.
