 FINA recognises world records in the following events for both men and women, except for the mixed relays, where teams consist of two men and two women, in any order.The long course meters (LCM) records are significantly older than the short course (SCM) records, and are generally viewed as the more prestigious of the two.LCM records originate as early as the early 1900s (later in the cases of butterfly evolving out of breaststroke).
