“If you ask the average boy to throw a baseball as far as he can, he will lift his elbow and wind his arm far back. A girl will tend to keep her elbow static and push forward with her hand in a motion not unlike that of a shot putter. Why the difference? Our correspondent mentions that he has heard theories that females have an extra bone that prevents them from throwing “like a boy.” Or is it that they are missing one bone? We talked to some physiologists (who assured us that boys and girls hav...e all the same relevant bones) and to some specialists in exercise physiology who have studied the underperformance of girls in throwing. In their textbook, Training for Sport and Activity: The Physiological Basis of the Conditioning Process, Jack H. Wilmore and David L. Costill cite quite a few studies that indicate that up until the ages of ten to twelve, boys and girls have remarkably similar scores in motor skills and athletic ability. In almost every test, boys barely beat the girls. But at the onset of puberty, the male becomes much stronger, possesses greater muscular and cardiovascular endurance, and outperforms girls in virtually all motor skills.MoreLessRead More Read Less
