To differentiate between pool sizes for swimming times, the following for a sanctioned meet, the pool length must be measured and verified. length by 75 feet [ m] in width, providing for eight, 9-foot [ m] lanes .. the accumulation or overflow of pool water onto the deck area where meet. The length of a long course racing pool is 50 metres. The pool There are normally 13 individual events and three relays for men and women in a swim meet.
As of January 1,men are only allowed to wear suits from the waist to the knees. Women[ edit ] Women wear one-piece suits with thicker and higher backs for competition, though two-piece suits can also be worn during practice. Backs vary mainly in strap thickness and geometric design. Most common styles include: There are also different style lengths: As of January 1,in competition, women must wear suits that do not go past the shoulders or knees.
Use of drag wear[ edit ] Drag suits are used to increase water resistance against the swimmer to help them train for competitions. Other forms of drag wear include nylons, old suits, and T-shirts: Some swimmers practice in basketball shorts over their bathing suit, wearing two bathing suits, or wearing an extra bathing suit with holes cut in the material.
Many swimmers also shave areas of exposed skin before end-of-season competitions to reduce friction in the water. The practice gained popularity after the Olympics, when Murray Rose and Jon Henricks came shaved and won gold medals for Australia. In addition, a study demonstrated that shaving improves a swimmer's overall performance by reducing drag.
Drag makes a swimmer feel slower and more resistant during training with the added friction. Then on the day of the competition, a shaven swimmer wearing only a fast competition suit will feel an improvement in how fast and smooth they feel in the water. This is caused by the swimmer's own fatigue. When the swimmer becomes more fatigued, different muscle groups become more tired.
Consequently, the swimmer will try to engage another group of muscle to do the same thing, which can cause the stroke efficiency to drop. Professionalism[ edit ] Swimming creates a mix of levels, including: Fully professional swimmers will typically get a salary both from their national governing body and from outside sponsors, semi-professionals a small stipend from their national governing body, and amateurs receive no funding.
Full body suits have been banned, but swimmers at the very top levels still wear suits that have been lasered together because stitching creates drag. The disadvantage of these suits is that they are often uncomfortable and tight, and can tear easily if not handled carefully.How to warm up prior to swimming (Matt Taylor) Speedo Advisors - Presented by ProSwimwear
The largest Ocean Swim's in terms of numbers of participants are in Australia, with the Pier to PubCole Classic and Melbourne Swim Classic all with roughly swimming participants. Changes to the sport[ edit ] Swimming times have dropped over the years due to superior training techniques and new technical developments.
The first four Olympics were not held in pools, but in open water — the Mediterranean, — the Seine river, — an artificial lake, — the Mediterranean. The Olympics ' freestyle race was the only one ever measured at yards, instead of the usual meters. A meter pool was built for the Olympics and sat in the center of the main stadium's track and field oval. The Olympicsheld in the Stockholm harbor, marked the beginning of electronic timing. Competition suits now include engineered fabric and designs to reduce swimmers' drag in the water and prevent athlete fatigue.
In addition, over the years, pool designs have lessened the drag. Some design considerations allow for the reduction of swimming resistancemaking the pool faster. These include proper pool depth, elimination of currents, increased lane width, energy absorbing racing lane lines and gutters, and the use of other innovative hydraulic, acoustic, and illumination designs.
There have been major changes in starting blocks over the past years.
Starting blocks used to be small, narrow and straight  but through time they have become bigger and wider and nowadays the surface of the block is angled towards the swimming pool. This stroke is characterized by the alternate overhand motion of the arms.
The freestyle is swum over 50,and metre distances. Backstroke Events In the backstroke, the swimmer must stay on his or her back at all times. The stroke is an alternating motion of the arms. At each turn a swimmer must touch the wall with some part of the body. Swimmers must surface within 15 metres after the start and each turn.
Backstroke race distances are and metres. Breaststroke Events Perhaps one of the most difficult strokes to master, the breaststroke requires simultaneous movements of the arms on the same horizontal plane. The hands are pushed forward from the breast on or under the surface of the water and brought backward in the propulsive stage of the stroke simultaneously.

The kick is a simultaneous thrust of the legs called a frog or breaststroke kick. No flutter or dolphin kicking is allowed. At each turn a swimmer must touch with both hands at the same time. Breaststroke races are distances of and metres. Butterfly Events The most physically demanding stroke, the butterfly features the simultaneous overhead stroke of the arms combined with the dolphin kick.
The dolphin kick features both legs moving up and down together. No flutter kicking is allowed. The butterfly was born in the early s due to a loophole in the breaststroke rules and became an Olympic event in Melbourne, Australia in Butterfly races are swum in and metre distances.
Individual Medley The individual medley, commonly referred to as the I. Medley Relay In the medley relay all four strokes are swum by four different swimmers. No swimmer may swim more than one leg of the relay, which is swum in backstroke, breaststroke, butterfly and freestyle order.
The medley relay is metres -or four by metres.
