Fourteen measures, thought to cover all aspects of the contents of fundamental motor ability, were administered to 228 boys and 329 girls. Principal factor analysis was applied to the correlation matrix which was calculated with the fourteen variables. The first Principal factor extracted (named as a fundamental motor ability factor) and the elements which forms the fundamental motor ability factor were investigated in each age, respectively. The results were 1) The fundamental motor ability of boys and girls of these ages increased almost linearly with the increase of age; 2) As for the size of fundamental motor ability, it was, greater in boys at all age levels than in girls; 3) Sex difference in fundamental motor ability was found at 4.5 years of age, and it became greater with the increase of age; 4) The fundamental motor ability of boys aged four to six years was considered to be mainly composed of physique, muscular strength and explosive strength on upper and lower limbs, while that of girls was considered to be mainly composed of physique, maturity and muscular strength.
