PHV stands for Peak Height Velocity, representing the period during childhood when the maximum rate of growth occurs. It's essentially the "growth spurt."
Here's a more detailed explanation:
-
Definition: Peak Height Velocity signifies the point in time when a child experiences their most rapid increase in height. This rapid growth signifies the transition from childhood into adolescence.
-
Significance: PHV isn't just about height; it indicates broader hormonal, physiological, and anatomical changes happening within the body.
-
Alternative Name: It's also commonly known as the growth spurt.
-
Timing: The timing of PHV varies among individuals. Generally, it occurs earlier in girls (around ages 11-13) compared to boys (around ages 13-15).
-
Indications: PHV involves significant changes beyond height, including the development of secondary sexual characteristics and changes in body composition.
