Men's 4x100m | The Exchange Zones Decided Everything

South Korea defeated a relay team anchored by the double sprint champion of these Games — and the margin tells the whole story. By the end of this breakdown you will understand exactly why relay execution beats individual speed, and where the race was really decided. The 4x100 meters, World University Games, Bochum: one final, four teams, and 0.39 seconds separating gold from fourth place. The exchanges, the baton velocity model, the synchronization gap — this video makes visible what a broadcast camera cannot show you. South Korea's 38.50 national record was not built on faster legs. It was built on cleaner zones. And behind them, India and Australia finished in the same recorded time — separated only by five thousandths of a second at the photo finish. This is what relay precision looks like at the top level, and why the team with the most raw sprint talent does not always win.
