Since that celebration from the South Korean striker was widely shared on social media

Many wondered about the reason behind the wearing of this piece of clothing by the footballers

[{"selector":"#anim-70d0aa42-0e26-490a-aa73-b36f2851be33","keyframes":{"opacity":[0,1]},"delay":0,"duration":1000,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-d82f10e3-5c27-456a-a81e-abc338012b34","keyframes":{"transform":["translate3d(0px, 199.40630%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":1000,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-508382ce-204c-4b5e-b1bf-0297fa35be12 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(-48.848684241478054%, 0, 0)","translate3d(0%, 0, 0)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}]

Few even questioned if Hee-Chan was wearing a woman’s sports bra.

These sports bras are officially called the GPS tracker vest and are very common among male footballers.

The vest has a GPS device connected to it which helps the experts understand the GPS readings of the player.

[{"selector":"#anim-fc153bcd-5b02-43e4-9d84-8bf6f9d3928c","keyframes":{"opacity":[0,1]},"delay":0,"duration":1000,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-8559814d-77a6-4897-a7db-d445bf885e86","keyframes":{"transform":["translate3d(0px, 180.45423%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":1000,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-70b9b874-b87e-4437-bcaa-18e8bf672828 [data-leaf-element=\"true\"]","keyframes":{"transform":["translate3d(-27.240953805677503%, 0, 0)","translate3d(0%, 0, 0)"]},"delay":0,"duration":2000,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}]

Reports have hinted that the data collected helps the team managers and trainers to learn details such as how fast or far a player ran during training or a match.

The GPS data is not restricted to the Football. Several other sports such as Basketball etc. have used this technology
