Peak Height Velocity (PHV) describes the period of fastest stature growth during adolescence. It cannot be read from chronological age alone. Growth pattern, puberty context, training history, pain and recovery must be considered together.
PHV is not a talent score. It must not be used to select, rank or exclude a child from a sport.
The strongest approach: serial measurement
The most informative way to understand PHV context is to track annual growth velocity from repeated, standardised height measurements. Time of day, equipment, shoes and posture can create small but misleading differences. The platform therefore shows the date and freshness of the latest measurement and asks the family to confirm or update it.
Single-occasion anthropometric equations can estimate approximate distance from PHV. Mirwald and colleagues developed a maturity-offset approach, but it has prediction error and a limited application window. Read the original method.
Why it is an attention window
Longitudinal studies in male youth athletes suggest that some injury incidence or burden can rise around the growth spurt. Much of the evidence comes from elite male football and cannot be generalised to every child. Review a PHV injury-burden cohort. A 2025 systematic review also found a possible association while rating the certainty of evidence as very low. Read the review.
This does not mean every child will be injured. A safer interpretation is to revisit the plan when rapid growth appears alongside new pain, coordination changes, poor sleep or a sudden rise in training load.
A weekly family-and-coach check
- Date of the latest height measure and change over the previous 6–12 months
- Recurrent knee, heel, hip, back or shoulder pain
- Training and match exposure and recent abrupt change
- Sleep, appetite, school fatigue and enjoyment
- The child's perceived effort and wish to continue
- Temporary changes in technique, balance or coordination
When signals appear, the goal is not automatically to stop sport. Reduce painful or high-impact volume, keep suitable skill and coordination work, increase recovery and seek sports-medicine or physiotherapy review when appropriate. One academy study found lower injury burden after an interdisciplinary, individualised prevention approach; it is promising but not universal proof. Read the study.
How the platform uses this context
The LTAD Development Hub never turns PHV into a stand-alone stage decision. Growth, movement competence, health, load, recovery, motivation and the child's own goals are reviewed together. Low-reliability data create a measurement-verification task rather than a recommendation.
Red flags
Rest or night pain, marked swelling, inability to bear weight after trauma, neurological symptoms, chest pain, fainting, breathlessness or progressive loss of function need health assessment rather than continuation of an online plan.
