Foundational specification of modern long-track speed skating. The ISU standardized the 400m oval as the international competition surface and codified the race distances for World Championships in 1892 — the same year as the ISU's founding. The 400m oval has remained the operative long-track standard worldwide for 130+ years, with subsequent refinements (lane width, banking, ice composition) building on the original standardization. Defines what counts as a sanctioned long-track race.

ISU formally adopted short-track speed skating as a recognized competitive branch — mass-start races on shorter tracks (typically 111.12m oval inside a hockey rink), complementing the long-established 400m long-track speed-skating discipline. Adoption brought the discipline under ISU sanctioning and rule-making, eventually leading to the first World Championships in 1981 and Olympic acceptance in 1992. Foundational expansion of the ISU's competition portfolio and the basis of all subsequent short-track regulations.

ISU tightened the short-track false-start rule to immediate disqualification on first offence: an athlete who breaks before the start signal is removed from the race outright, eliminating the prior warn-then-disqualify procedure that had stood for many years. The change mirrors the strictness World Athletics adopted in 2009 for track and field running events and addresses the disproportionate disruption a single false start causes in mass-start short-track racing where lane discipline is critical to safety.
