rs for swimming can be demonstrated in the arm stroke and the front crawl. Arm muscles provide the force and the shoulder is the pivot point. Water is the resistance, which comes from the arm during the strokes. The way to improve leverage is to use less force when swimming. For example, the front crawl a swimmer can perform this by bending the elbow, this reduces the force when needed.Front crawl or freestyle is both the fastest and the most efficient swimming technique. The ideal body position for the front crawl is having your body horizontal, with your body stretched out in a straight line. Your face should be in the water, except when you come up for air, with the water at about the hairline. You should look forward and slightly downward. The arm stroke for the front crawl is generally one arm pushing back, and the other arm coming from your side. In the front crawl, the arms provide about 80 percent of the propulsion, more than any other stroke. The best way to use your arms efficiently is in an elongated arm pull. This gives you better propulsion on the water because you are always pushing against still water rather than water that is already in motion. There are five phases in the arm stroke: 1. Entry 2. Catch 3. Pull 4. Follow-through 5. Recovery. Two important things to remember when learning the stroke: 1. Keep elbows high 2. Accelerate your hand speed until you have completed the follow-through.The leg kick generally performed using this method of swimming is the "flutter" kick. The flutter kick provides only about 20 percent of the propulsion. To do the flutter kick, move your legs up and down alternately in a steady, strong, constant motion. As you kick downward, bend your knee slightly and keep your ankle loose. As you kick upward, hold your knee relatively straight and raise your foot until your heel breaks the water surface. If you bring your feet too far out of the water, may make a big splash,...
