my nephew is running in the cyo prelims today. i am curious how much time difference a composite track will add to his time. i am not interested in Olympics. he is 8th grade Track and Field.
i ran a 24.7 200 in state and got 4th so.. and if you run under a 12 in the 100 meter dash that's pretty good, i run a 12 flat.
Yes, as will fast walking and swimming, etc. Though, running on hard surfaces, while wearing unsuitable footwear, may eventually cause damage to ankle and leg joints
Yes, different surfaces can affect a runner's speed. Soft surfaces like grass or sand can slow down a runner due to increased resistance. Hard surfaces like pavement or track can be faster for running as they provide better energy return and responsiveness.
Land surfaces warm faster and cool faster
paper
Black surfaces absorb a wider range of wavelengths of light compared to white surfaces, which allows them to absorb more energy and heat up faster. When black surfaces absorb heat, they also emit it at a faster rate due to their higher emissivity, contributing to their faster heat radiation compared to white surfaces. White surfaces, on the other hand, reflect more light and heat, which reduces their rate of heating and heat emission.
Friction
Slower
You get to mcdonalds faster running
Land surfaces heat up and cool down faster than water surfaces.
A smooth surface like glass or polished wood will likely cause a toy car to roll faster due to reduced friction. In contrast, rough surfaces like carpet or concrete may slow down the toy car due to increased friction and resistance.
surfaces that are rough provide more friction that can make athletes run faster
