A sprinter who is running a 200




















To do this successfully, explode from the blocks, driving your feet hard into the ground. This is not the same as the acceleration phase of the m. Running a successful bend can be the difference between winning and losing the race. This can be difficult for an athlete to understand let alone achieve.

Gliding does not mean to slow down or exert less effort. You want to take the momentum built up from your acceleration and use it to maintain your speed as you sprint the bend. This will allow you to run with a long and comfortable stride. Running m from the m start line in training is a good way to practice this. Eventually, you will get a feel for it and know how much energy you have left in the tank once you come off the turn. Remember that everyone is decelerating.

Note: Make sure you run your own race and stick with your plan! When you obsess over what others are doing then you have already lost. To run a successful bend, you do not need to lean your body into the curve. Focus your sight on the point at which you want to run and your body will naturally follow around the bend.

During this phase, you want to re-accelerate. Before you say this is impossible, I realise that this is not what is actually happening here.

As you come off the bend you want to kick start that rapid arm and leg movements that you produced during the first 40m.

You should feel a shift in your efforts the re-acceleration as you use that reserve that you saved from gliding the bend and continue for the next 30m. But he was unable to add to his resume of wins as the mistake took him out of the results.

A body moving in a circle must therefore have a force on it continually causing the change in direction. This force is called centripetal force centripetal means toward the center.

The sprinter needs to change course, turning to follow the curve. Friction between their feet and the ground provides the centripetal force. However, the sprinter's center of mass is some distance above the feet, and that is a problem. Assume the sprinters run the course in a counterclockwise or anticlockwise direction. The friction, trying to accelerate the sprinter toward the center of the curve, provides a clockwise torque as viewed from behind which would tend to make the sprinter fall toward the outside of the curve -- unless some way to counter that torque with an equal and opposite torque were found.

When the sprinter leans toward the center of the curve, the force of the sprinter's weight is still a vertical force and it points to a spot on the ground toward the center compared to where the feet are. That provides a counterclockwise torque to oppose the clockwise torque that following the curve generates. Why does a sprinter running in a m event lean towards the centre of the curve he is rounding?
