This reports the results of analyzing the developmental process of muscular strength (grip strength) of Mlaburi people through infancy to adult ages.
1. The developmental process of muscular strength shows a sigmoid curve, so-called growth curve.
2. Comparing by sex, men exceed women in every age class.
3. The muscle development of men continues from 10 to around 20 yrs old, and women from 8 to 17 yrs old, including the adolescent spurt.
4. A small but apparent acceleration appears in men's infancy muscle development.
5. Grip strength-weight ratio was higher in Mlaburi group than in Japanese and Thai group in all age. This indicates that the environment of Mlaburi people required more physical use in their daily life.
