Growth spurts and injury risk: what parents of youth footballers must know

During the youth years, most young footballers hit the fastest phase of their growth spurt. In the months around this phase, the risk of injury can be much higher than in the years either side. Most parents never hear about it.

Why growth spurts increase injury risk

Bones grow first. Muscles and tendons catch up later. During this gap, players experience:

• Temporary loss of coordination as limb lengths change.
• Reduced flexibility as muscles are pulled tight over rapidly lengthening bones.
• Open growth plates that are more vulnerable to overload — the source of common conditions like Osgood-Schlatter's, Sever's disease and Sinding-Larsen-Johansson.
• Higher body mass moving through the same joints.

How to spot a growth spurt

You usually notice it before the player does:

• Trousers and boots that fit a month ago are suddenly short.
• Complaints of aching knees, heels or shin pain — often worse the day after training.
• Clumsiness they didn't have before: heavier first touches, awkward landings.
• Increased tiredness and longer recovery from normal sessions.

Adjusting training load through a growth spurt

This is not the time to add extra sessions, even if your child is being scouted or the coach is pushing more minutes. Instead:

1. Hold weekly load steady — resist the urge to progress. Match volume to what the body could handle a month ago.
2. Keep weekly progressions smaller during the spurt than at other times.
3. Double down on mobility and controlled strength — hamstring work, calf raises, hip mobility.
4. Cut jumping and impact volume for a few weeks if heel or knee pain appears.
5. Prioritise sleep. Growth and recovery both happen at night — extra rest is not excessive at this stage.

Talking to the coach

Coaches usually welcome the information — they just rarely have it. Share what you're seeing: recent growth, symptoms, sessions per week outside the club. A short conversation can prevent a season-ending injury.

YouthLoad flags likely growth-spurt windows based on growth patterns and reported symptoms, and automatically lowers the recommended weekly load ceiling during those high-risk periods.
