02The growth of one child

After each measurement you see the growth period, the biological age and when the growth spurt starts, peaks and slows down. The chart shows height, sitting height and weight over time. Further down the page are all measurements and the do's and don'ts for this period.

Daniel
P2 · Growth spurt - accelerated growth period

Daniel is in the growth spurt. The fastest growth is around August 2026. We expect the growth spurt to slow down around February 2027.

P2Training in the growth spurt - accelerated growth period
Based on the Athletic Skills Model

During the growth spurt bones grow faster than muscles and tendons. Your child may be a little clumsier for a while and is more prone to overload.

Do
Suits this phase well
Technique & coordination

Lots of different movements help your child get to know their body again.

Recovery

Your child now needs more rest between hard practices.

With care
Offer in adapted or limited form
Sprinting

Short sprints are fine, with plenty of rest in between.

Jumping & landing

Few jumps. Watch for pain in the knee or heel.

Better not
Avoid in this phase
Strength with weights

Preferably no heavy weights until after the growth spurt.

03For parents

Parents give consent and can then follow along with their own account. They see their child's growth period in plain language, with what does and does not suit this period.
