Times have consistently dropped over the years due to better training techniques, new developments in the sport and swimwear changes (e.g. Goggles were not widely used until the 1970s, providing for considerable expansion of practice/training time.)

1904 Olympics freestyle race was the only one ever measured at 100 yards, instead of the usual 100 metres. A 100-metre pool was built for the
1908 Olympics and sat in the centre of the main stadium's track and field oval. The
1912 Olympics, held in the Stockholm harbour, marked the beginning of electronic timing.
Male swimmers wore full body suits 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 currents, increased lane width, energy absorbing racing lane lines and gutters, and the use of other innovative hydraulic, acoustic and illumination designs.
