Brazil Turns to 'Smart Vests' in Quest for World Cup Success

Brazil’s football program is incorporating “smart vests” into its training regimen. The wearable technology is intended to monitor player performance in real time. Officials say the data will help fine‑tune tactics ahead of the World Cup. The vests collect metrics such as heart rate and movement patterns. Coaches hope the insights will give Brazil a competitive edge. The initiative reflects a broader trend of tech adoption in elite sport. Players will wear the devices during practice sessions and possibly matches. Success of the program could influence future preparations for major tournaments.
