ResumoAbstract The X-ray films of the hands of 55 boys in the Little League World Series, 1957, were assessed for maturation (skeletal) age according to Todd's 1937 standards. There were four boys of chronological age 11:0–11:9, 42 of age 12:0–12:11, 9 of age 13:0–13:11. It was found that 16 boys (29%) were retarded, or maturation age less than chronological age; 39 boys (71%) were advanced, or maturation age more than chronological age. With correction of maturation age within ± one year of chronological age, the significant figures are five retarded, 25 advanced, for a total of 30. Of these 17 percent are retarded, 83 percent advanced. It is concluded that Little League ball players of championship caliber are, in general, biologically advanced. Such an advancement is deemed a positive factor in young boys indulging in competitive sports.
