Master of The ultimate split second
dave Time your sprint start to discover how sound and nerve speeds limit Olympic reaction times.
dave Olympic 100m Reaction Time
Wait for the signal, don't you jump too fast (no, don't you go!) / A tenth of a second is the boundary line (yeah, that's the line!)
Starting line sound: In the 100m sprint, runners in outer lanes hear a traditional starting gun 0.15 seconds later than runners in inner lanes.
dave The auditory cortex of the brain processes the sound of the starting gun before sending a signal to the legs.
What medium does the sound of a traditional starting gun travel through to reach a sprinter's ear?
Which part of the brain is responsible for first processing the sound of the starting gun?
How long does it take for a sound wave to become an electrical signal in the inner ear?
