f-swimming1The science of swimming is extremely complicated, involving the interaction of propulsive forces from the swimmer’s arms and legs and the drag caused by water. However, by applying new research courtesy of fluid dynamics and supercomputers, every swimmer can swim faster. 

Few sports are as precise as swimming. Cyclists can blame the wind, runners the terrain and team sports players the referee! Swimming, on the other hand, has exact distances and water is, well, constant. However, although ‘pure’ swimmers race in the pool and triathletes in open water (or OW as it’s referred to), the advent of long-distance swimming entering the Olympics in Beijing and fast-moving swimsuit and wetsuit technology means that many ‘constants’ in the world of swimming aren’t so constant after all.

The ‘sports ground’ for swimming (H2O!) is often quoted as being 1000 times denser than air. Trying to move efficiently through this very dense medium is not nearly as easy as other sports that take place through air. For example, top cyclists hit over 60kmh in short events on the track or in an end-of-stage sprint. Elite runners average over 30kmh for a quarter mile and over 40kmh at the end of sprints. By contrast, even the world’s best swimmers top just 8kmh (5mph)  over the 100m sprint. Yet that is still superhuman. Most fitness swimmers would fail to approach even half that speed. All that splashing around by even the most enthusiastic fitness swimmer is soon put to shame by the 12 year old who glides through the water with ease. In short, swimming is about brain not brawn, and it’s technique not triceps or trapezius size that matters.

f-swimming2The efficiency of your swimming stroke is the key to success as a competing or training swimmer. An efficient stroke will significantly reduce wasted energy output through less drag in the water and a cleaner execution of hand and arm entry and recovery. Thus that little extra energy may provide you with an overall faster time. When your energy resources are depleted and you're hanging on to the end of your race, you will be the winner if you can hold your technique to that last tenth of a second. Every swimmer knows how easy it is to let one's technique drop off as you become more fatigued throughout a race - that burning sensation in the shoulders as you try to hold together your last few strokes to the wall is the hardest part of the race.

With regard to training for competitions, the season can last for up to 10 months or more, depending on whether you are at county, national or international level. In general, the season's training will reflect the level of the club or squad you are training with. The season will be geared around the county or regional championships, the Grand Prix circuit, the nation short- and long-course championships, the European, World or Olympic Games or the World Cup Circuit. Whatever your level, this article aims to cover the different types of training sets/sessions you should experience. Your individual ability and/or standard will determine the actual proportional breakdown of these sessions or cycles throughout the swimming season.
