Question 2

What’s PHV?

Peak-

Answer 2

Peak Height Velocity (PHV) is the maximum rate of growth in height that occurs during a growth spurt.

Girls reach their peak height velocity of an 8 cm increase per year at around age 12. On the other hand, boys typically reach their peak height velocity of a 10 cm increase per year at around age 14.

Question 3

What are critical periods?

Answer 3

Critical periods are certain periods of growth and development.

For example, during the transition from childhood to puberty (around the beginning of the teens years), hormonal changes make our bones more susceptible to growing and becoming denser. This is, therefore, a critical period of human growth and development.

Proximodistal sequence: Body movements that originate close to the center of the body develop earlier than those that originate farther away from the center.

Hormonal/Glandular activity.
Heredity
Nutrition/Diet
