By: Tilar Law, William Duff, Zoe Howell The Physics of the 100 meter dash
The Mechanics of Sprints • Body Position • Arms • Legs • Head • Inertia • Speed and Acceleration
Body Mechanics • Head • The head should stay level with the jaw at a forward constant position during the duration of the race.
Body Mechanics • Arms • While running keep your arms at a 90 degree angle to your elbow and let them naturally flow. Your arms swing as a counter to the forward movement produced by your legs while running. • Creating this movement is due the flexibility of the runners shoulder gridle
Body Mechanics • Legs • Legs trust downward and back at 50-55 degrees • Legs should be in flexion to reduce the inertia and make forward movement easier • The lifted leg should never reach a horizontal position while running
Inertia • At the starting point of the race, Inertia is working against the runner. • In order to speed up the runner must make short and quick strides to gain speed. • As the runner speeds up, their strides become longer to cover a farther distance.
