A/B/C Meet:

Meet that has three categories of racing: swimmers who have achieved A times, swimmers who have achieved B times and C swimmers, who have not yet achieved B times in the event(s) they wish to race.

Age Group:

Division of swimmers according to age. The National Age Group divisions are: 10-under, 11-12, 13-14, 15-16, 17-18. Some LSCs have divided the swimmers into more convenient divisions specific to their situations: (i.e.) 8-under, 13-Over, 15-Over, Junior, Senior.


In a Prelims/Finals meet, after the finalists are decided, the next two fastest swimmers other than the finalists are designated as alternates. The faster of the two being the first alternate and the next being second alternate. If a finalist cannot participate, the alternates are called to take their place.

The primary rule is that swimmers must remain on their back for the entire race, with the exception of the last stroke before a flip turn. The stroke is a backward circular strokes of each arm alternately and a flutter kick.. This is the only stroke that requires an in-water start.

Backstroke Flags:

Pre-Seeded Heats:

Swimmers are arranged in heats in each event according to entry times. Heat sheets listing the lane and heat assignments are prepared prior to the day of competition.

Deck-Seeded Heats:

Swimmers are called to report to the Meet Director for their event on the day of the meet. After scratches are determined, the remaining swimmers are seeded into the proper heats and lanes. Swimmers are notified of their heat and lane assignment by means of individual cards or posted heat sheets.

Vertical (Circle) Seeded Heats:

A method of seeding swimmers when they are participating in a prelims/finals event. The fastest swimmers are seeded in the last three heats, with the fastest swimmer being seeded in the Heat 1, next fastest in Heat 2, next fastest in Heat 3.  Then the next fastest will be seeded in Heat 1, next fastest in Heat 2, next fastest in Heat 3.....and so on until the last 3 heats are full.

Horizontal Seeded Heats:

A method of seeding swimmers when they are participating in typically timed finals event. Seeding method is slowest to fastest.  Meaning the slowest swimmers (or No Time swimmers) swim in the first heat while the faster swim in the last heat.

Fastest to Slowest Seeding:

A seeding method used on the longer events held at the end of a session. The fastest seeded swimmers participate in the first heats followed by the next fastest and so on.


Swim workouts are divided into sets of swims in a particular stroke, style, and distance, such as kick sets, pull sets, distance sets, sprint sets, IM sets, etc with a particular purpose.  Sets are given in terms of the distance to be swum, calculated in yards or meters, depending on the pool.  Therefore, a "set" of "25’s" means swimming one length of the pool before resting; "50's" means two lengths, and so on.  

Senior Meet:

It often refers to making the body long and narrow (arms/hands together and outstretched, head down between arms, feet together pointed back) in the glide off the starts and walls, but it also applies to all aspects of the strokes.   The more swimmers can create a streamlined effect with their bodies, the more efficient they will be in the water


There are four competitive techniques (strokes):  Butterfly, Backstroke, Breaststroke, Freestyle.

Stroke Count:

Number of stroke during a swim

Submitted Times:

Times filed with an entry; as having been previously achieved.


In a Prelims/Finals type competition, a race after the scheduled event to break a tie. The only circumstance that warrants a swim-off is to determine which swimmer makes finals or an alternate, otherwise ties stand.

A test set used to determine a swimmer's threshold pace. After a complete warm-up, the swimmer swims their fastest sustainable pace for thirty minutes (can be other lengths of time)


The resting process during training for swimming competition.  Reduced training volume and intensity gives the body and mind a break from the rigors of intense training.  Coupled with quality rest, it allows the swimmer’s body time to repair itself and to restore its energy reserves to prepare for major competition.  Studies have found tapering to produce a marked increase in muscle strength. Tapers depend on the level of training the prior 3- 9 months  A perfectly designed taper will enable the swimmer to compete at their peak capability and is one of the most difficult aspects of swim coaching.   It is not magic but is designed to allow the body to gradually rest to help it over-compensate for the prior work loads.  Rest and more rest.


Touch Pad Time:

Time recorded by the electronic timing system when any part of the swimmer touches the touch pad - when used this will be the primary time

Button Time:

Time recorded by the electronic timing system when any part of the swimmer touches the wall/touch pad and the timer presses the button - when used this could be the primary or secondary time depending if touch pads are utilized

Watch Time:

Handheld watch used by timers to record a swimmer's time in an event. In meets with electronic timing, timers will still use stopwatches to record back-up times, in case the electronic timing system fails.

Timed Final Heat: 

A competition in which only heats are swum and final placing is determined by the times performed in the heats.

Time Standard:

The time standard for an event in a meet is the time a swimmer must have previously achieved to enter that event.

Time Trials:

An event or series of events separate from the main competition at which swimmers may achieve or better a required time standard

Tired Times:

Most swimmers, in particular, the older swimmers will be swimming most of the season tired and their times should be compared to swims during the same time of season/ month as swims from the previous year.  Best times will not normally be achieved by swimmers training effectively and hard as occurs during mid season.


At the end of the prescribed distance, the finish of the race.

Touch Pad:

The part of an electronic timing system that rest in the water at the end of each

lane. Swimmer's times are recorded when they touch the pad.

Unattached (UN):

An athlete member who competes, but does not represent a club or team

Underwater Recovery:

In Butterfly, a violation of the stroke rules when the arms fail to recover over the water.  Usually seen at the walls in the turns and the finish when the swimmer miscalculates the distance to the wall and during the swim by younger, inexperienced swimmers. It is also the legal means to recover on breaststroke.

Unofficial Time:

The time displayed on a read out board or read over the intercom by the announcer immediately after the race. After the time has been checked, it will become the official time.
