records were as follows. Jim Hines had a time of 9.9 seconds (hand-timed) or 9.95 seconds (auto-timed) in the final. This equalled the world record and set a new Olympic record, which were measured by hand-timing at that point. The 9.95 second time was recognized as the initial world record for electronic timed results when the IAAF changed its records rules in 1977.

Quarterfinal 4 Semifinals The top four runners in each of the two heats advanced to the final round. Semifinal 1 Semifinal 2 Final Mel Pender and Charlie Greene were known for their fast starts. In the final, while Greene reacted to the gun noticeably slower, Pender did not disappoint, taking a quick lead. Greene, Lennox Miller and Jim Hines were the next chase group, the three outer lanes already left behind. The diminutive Pender's lead disappeared, the much larger Miller leading the group in passing by the halfway point. Hines was just getting into gear, exploding past Miller and putting a gap on the field to take the race by two metres. Miller leaned but he already had a metre on Green who was a metre ahead of Pablo Montes, Roger Bambuck and Pender to take the bronze.
