Researchers at McMaster University in Canada believe that the body can get as much benefit…
British Olympics minister Tessa Jowell announced yesterday her aim to make swimming free for all by 2012, with the over 60’s enjoying free swims by the end of this year. This to help get the nation fit without creating an extra burden on the bank balance.
Western Australian Institute of Sport (WAIS) and the University of Western Australia can determine whether a change is beneficial without actually changing a swimmer’s technique, by inputting the 3D kinematics (body movements) of the swimmer, and then calculate the way the water moves around this 3D animation using ‘computational fluid dynamics’. This takes the ‘trial and error’ approach out of technique prescription. The video below demonstrates how they can model and measure the swimming stroke of world record holder Eamon Sullivan.

It is whether you use them and push their limits of endurance and strength. Build and maintain endurance by engaging in exercises that pump blood to the muscles, and strength by lifting weights, focusing on antigravity muscles (back, legs) and arms. Swimming can help with at least endurance and arm strength :-)

37 year old Jason Cull saw a dark shape approaching as he swam about 80 meters off the popular Middleton beach in Western Australia on Saturday. “I just remember being dragged backwards underwater. I felt along it, I found its eye and I poked it in the eye, and that’s when it let go.”
