Jumping higher - WOMEN !!
Women are Still Jumping Higher!
Since the early twentieth century, women have been participating in track and field events. Women's high jump has been one of the areas that has gained prominence in recent years. In fact, since 1932 World records were being compiled for this event. It was Jean Shiley of the USA who had the first world record in the high jump with a height of 1.65 metres. Since then, several countries such as Great Britain, Romania, Russia and Bulgaria have produced athletes who have been successful in breaking the world record over the years. Iolanda Balas of Romania stands out as one who has broken the world record eleven times!
