What do 100m sprinters wear?

Answer 1

Wear whatever is comfortable to you, as long as it doesn't oppose the following tips:

Do not wear something too baggy, for that will create drag and therefore slow you down. Also try to wear something lightweight.

Wearing compression clothing helps, for it creates a low amount of drag and gets more oxygen to your muscles. However, it will not make you the next Usain Bolt.

Spikes also improve your speed, but if you do not have them, run barefoot or in lightweight racers or runners. If you wear orthotics, take them out and replace them with the regular insoles that come with the shoe, if you can. You can buy spikes and shoes cheaply of Eastbay.com

Wearing wristbands, necklaces etc. will not slow you down, except if they are unusually heavy.

Remember, equipment does not make you win. It helps, but it is your technique, cadence and strength that will make the difference in the end. If you can train. Training is the real equipment that will make you win.

DEDICATION, PERSISTENCE, COMMITMENT.
