Short Answer
Complete Explanation
In competitive swimming, the abbreviation “DFS” appears in meet results and official documents to indicate that a swimmer has been “Disqualified for a False Start.” A false start occurs when a competitor leaves the starting block before the official start signal is given. Under the rules established by the International Swimming Federation (FINA) and most national governing bodies, a swimmer who commits a false start is immediately removed from the race and the result is recorded as DFS.
- Definition:
DFS = Disqualified for False Start. - Governing rules:
The rule is outlined in FINA Swimming Rules (Rule SW 4.4) and equivalent national regulations. - Typical usage:
Appears in result sheets, timing system outputs, and official meet summaries. - Impact on the swimmer:
The athlete receives a DQ for that event and may be subject to additional penalties depending on the competition’s policies. - Distinction from similar codes:
DFS is not to be confused with “DNF” (Did Not Finish) or “DSQ” (Disqualified for another infraction).
Common Misconceptions
DFS stands for “Did Not Finish.”
“Did Not Finish” is abbreviated as DNF; DFS specifically denotes a false‑start disqualification.
DFS is a timing metric like “Distance per Stroke.”
The metric for efficiency is DPS (Distance per Stroke); DFS relates only to a rule violation.
A swimmer can be re‑called after a false start if the starter realizes an error.
Under current FINA rules, any swimmer who leaves the block early is disqualified, regardless of subsequent clarification.
