The dynamics of display of power capabilities of different muscular groups for girls in ontogenesis is considered. More than 1000 girls of preschool and school establishments were inspected (age 4-13 years). There were taken types of tests in basis of battery of tests: dynamometry of prepotent hand; bending and unbending of hands in support, lying on the floor; hang on arcuated hands; raising of trunk in grey for 1 minute; broad jump and upwards from a place. It is set that speed-power potential of muscles of lower extremities is most expressed shows a tendency to growth for girls 4-7 years. Thus there is an increase speed-power to potential scope from 18% to 67,4% annually. It is set that the most favorable period of display of power endurance of muscles of humeral belt was observed from 6 to 9 years. A general tendency was thus saved to the increase from a year to the year of power potential from 35,5% to 40,6%.
