| Overview by IAAF | | |
| The London biomechanical report for the men’s hammer helped explain why Fajdek became World Champion for the third time. It included a graph showing the height of his hammer throughout his four turns. The wave got progressively steeper with a release point as the path approached a final peak. That point on his winning throw of 79.81 signalled a near-optimum release angle of 46.2°, which was described as “astounding” in the report. That was in round four. The Pole was already leading with 79.73 from his compatriot Nowicki (78.03), until Pronkin reached out to 78.16 in the sixth. Ten of the finalists used four turns. One used three, and the other five. For the first time in the history of the championships, the winning distance was below 80m. |
