Why do Male footballers wear “sports bras” during matches?
The “sports bras” male soccer players wearing are usually not bras at all. They are GPS performance tracking vests. They are electronic, for GPS tracking their positions in the pitch

It helps coaches measure things like:
Distance covered during a match or training.
Top speed and sprint frequency.
Acceleration and deceleration.
Heart rate (when paired with a heart-rate sensor).
Player workload and fatigue, helping reduce the risk of injury.
Teams analyze this data to:
Decide when a player should be rested.
Monitor recovery after injuries.
Improve fitness and training plans.
Compare performance over time.

Under their jerseys during training.
