There is a lot of emphasis on thefront crawl technique for a number of reasons, including:
- a good technique will make your swimming more efficient and enjoyable
- the water is producing 800 times more friction than the air. If your body is not well streamligned, aligned and hydrodynamic, if your movements are not smooth and you do not push the water in the right direction, you will be inefficient and you will become tired much faster than the swimmer with a good technique.
- good technique will reduce the risk of injury : the front crawl can generate a lot of stress on the shoulders which are a rather fragile and complex articulation; a good technique will reduce the constraints over your body.
- a good technique will develop the most appropriate and effective muscles for swimming : on this small chart is compared the muscle solicitation of two front crawl swimmers with a very different technical levels : you can see the direct influence of the technique on the solicited muscles. The swimmer “A” , who has a inefficient technique, will tend to overuse muscles that are not the most suitable for generating the necessary forces (especially deltoids and trapezes). On the other hand, the swimmer “B” with the best technique will use other muscles such as dorsal (big dorsal and big round), which are much more powerful and perfectly adapted to the effort to be provided in swimming:
