Youth speed: what actually improves, and when
A short, honest guide for parents: what changes speed in a 10–18-year-old, what doesn't, and how to tell the difference in six weeks.
Most youth speed programs sell cones, ladders and effort. Speed in a growing athlete comes from three things we can measure: how much force they put into the ground, how fast they produce it, and how well they hold position when they do. Everything else is a drill.
This guide explains those three in plain language, what a normal six-week change looks like at each age, and the two questions to ask any program before you pay for it.
Where speed comes from
Sprinting is a series of short, hard pushes into the ground. The athlete who pushes harder, faster and in the right direction is faster. Ground contact in a sprint lasts about a tenth of a second, so the force has to be produced quickly: which is why strength alone is not enough and why 'rate of force development' shows up in our testing.
For younger athletes (roughly 10–13), coordination and posture change results more than strength does. From mid-adolescence, the growth spurt adds mass and lever length; strength training becomes the main driver and the technique work protects it.
What a real six weeks looks like
A 10-metre time improving by 0.05–0.10 s in a block is a real change for a trained youth athlete; bigger jumps usually mean the first test was a bad day. Jump height on a force plate moving 1–3 cm is meaningful; the same test moving 8 cm in six weeks is measurement noise or a growth spurt.
We report every change next to the amount of noise in the test, so nobody chases a number that isn't there. That is what 'MDC' means on the results page.
Two questions to ask any program
Ask how they measure speed, and ask to see a before-and-after from a real athlete with the test error shown. If the answer is a stopwatch and a feeling, the program may still be good, but nobody can tell you whether it worked.
Our answer: timing gates and force plates, retested every block, results in your phone the same day, and a free 30-minute evaluation before anything is sold.
