Notable changes to the sportEdit

Times have consistently dropped over the years due to better training techniques and new developments withinin the sport.

In the first four Olympics, competitions were not held in pools, but rather in open water (1896, the Mediterranean Sea; 1900, the Seine; 1904, an artificial lake; 1906, the Mediterranean). The 1904 Olympics' races were the only ones ever measured in yards, instead of the usual metres. A 100-metre pool was built for the 1908 Olympics and was located in the centre of the main stadium's track and field oval. The 1912 Olympics, held in the Stockholm harbour, marked the beginning of electrical timing.

Male swimmers wore full body swimsuits up until the 1940s, which caused more drag in the water than their modern swim-wear counterparts. Also, over the years, pool designs have lessened the drag. Some design considerations allow for the reduction of swimming resistance making the pool faster. Namely, proper pool depth, elimination of waves, elimination of currents, increased lane width, energy absorbing racing lane lines and gutters, and the use of other innovative hydraulic, acoustic, illumination, and swimwear designs.

The 1924 Olympics were the first to use the standard 50 metre pool with marked lanes. In the freestyle, swimmers originally dove from the pool walls, but diving blocks were incorporated starting at the 1936 Summer Olympics. The flip-turn was developed by the 1950s. Swimming goggles were first allowed in 1976.

The butterfly stroke events were not held until 1956. Previous rules permitted the butterfly stroke in breaststroke races. After 1956, when these rules were changed, butterfly became its own stroke entirely.

Women were first allowed the longer distance of 800 metres freestyle in 1968, which remains the longest distance for women in the swimming pool. Up until then, women were considered to be too "delicate" to swim a race this long[citation needed], even though the men had had the 1,500 metre freestyle from the very early years.

Both men and women were granted the 200 metre freestyle race in 1968, giving swimmers an intermediate distance race between 100 metres and 400 metres.

Women's teams were first granted the 800 metre freestyle relay race in 1996 - even though there had been a men's relay race at that distance since 1912. At six Olympiads, the men had two freestyle relay races, but the women only had one. Now, both sexes have two.

The medley relay races (4×100 metres) were not held for men or for women until 1960, but they have continued in every Olympiad since then.

Starting in 2008, both men and women compete in 10 km open water marathon swim events.

NotesEdit

  1. ^ a b c d e f g h i Distances at the 1904 Olympics were measured in yards rather than metres. The 50 yard freestyle was 45.7 metres and the 100 yard freestyle and backstroke races were 91.4 metres. The 220, 440, and 880 yard freestyle races were 201, 402, and 805 metres, respectively. Instead of a 1500 metre race, there was a 1 mile race which made for 1609 metres. The 440 yard breaststroke, like the freestyle, was 402 metres. The relay, 4 × 50 yards, was 4 × 45.7 metres.
  2. ^ In 1920, the women's event was 300 metres.
