Analysis
World Athletics treats a reaction time under 0.100 seconds as evidence that a sprinter moved before the gun. That threshold is a claim about human physiology, and a study on instrumented blocks found five of nine athletes averaging under it.
Sports Science
Dip before you jump and you jump higher. The gap between a countermovement jump and a squat jump is treated as a readout of elastic energy — but a review of the mechanisms concludes elastic energy is a small contributor, and that a bigger gap may be the worse sign.
One mechanism, taken apart carefully.
Explainers
World Athletics defines the finish as the instant a specific part of a specific body reaches a vertical plane. Producing that instant takes a camera aligned with the line, a thousand frames a second, and a test run before every session to prove the clock started when the gun did.
Explainers
A record stands or falls on a wind reading averaged over ten seconds at one point beside lane one. The rule that converts that reading into a number is not symmetrical, and the asymmetry always runs the same way.
An argument about how the sport behaves, with the evidence for it.
Longer pieces on the built and designed side of the sport.

The evergreen pages these 8 stories draw on, most-cited first.
A sport gets a page here once the Journal has published at least 4 stories on it in at least two different forms. Everything else the publication covers is listed onTopics.
