A woman naturally has more fat-as previously mentioned, 10 percent than that of an equal well-trained man. As the fat is a kind of limited fuel in the activity of durability (birds' migratory basically rely on fat), women can run for very long without "hitting the wall", that is, the fuel exhaustion and your legs have to move slowly with difficulty to the painful moment. Nena Cusick said to me, "I have taken part in the marathon game 35 times and never hit the wall. Though I was, I could hold out."

It is generally admitted that more proportion of fat means less proportion of muscles. However, some study reports demonstrate that compared to the muscles per pound, women are as strong as men.

It is quite the contrary to a fantastic statement. Gathering the materials provided by 361 schools, more than 125 track coaches and several public reports, Doctor Kristin New Jersey Medical College Joan Gillet from Nevada University came to a conclusion that a woman as well as a man who is well trained is not apt to be injured. One exception is women's knees are a bit likely to be injured for their joints are softer.

Moreover, women benefit by exercise as much as men do. Leroy Gushier and J Moore made a comparison of men to woman under a close supervision plan. They says that women's state of health are amended as men after exercise in the Document of Physical Medicine and Function Recovery. Someone holds that men need and benefit from exercise, while women dose not. That is no more than a fraudulent myth. This view is particularly dangerous after menopause, because some parts of the heart immune system of women have disappeared, and they start to have a heart attack as easily as men.

Then why do people generally consider women as the second-rate citizens in terms of track and field.

The main reason seems to be the aspect of culture. Catharine Reims does not only think deep in the problem but also take many of her conclusions into a sensible and insightful book called Running for Health. When I converse with her, she talked indignantly about how the society complicit in blocking women from discovering the pleasures of athletics. She said: "women are conscious that they are spending too much time on sitting. But no one has ever told them to go out and learn an exercise as men. Women are only told to make a graceful bending down posture when doing household duties so as to achieve the goal of exercise. If you were a woman, people would always urge you on taking some stupid exercise at home, in the office or on the way to market hall. This results from cultural prejudice".
