Peak height velocity

Peak height velocity (PHV) is the period during adolescence when a person experiences their fastest growth in height. It marks the point when their body is growing most rapidly, typically occurring around ages 11-14 for girls and 13-16 for boys. This growth spurt is driven by hormonal changes that stimulate bones and muscles to grow quickly. PHV is a natural part of puberty and indicates that a person is nearing the end of their growth phase. Monitoring this stage helps in understanding developmental progress and planning for growth-related health care.
