In the contest item of the track and field events, the item of any more than 200 meter, the athletes all turn left curved(negative the hour hand direction), this is why?The reason has two followings:
It one, the person's heart locates the left side of the body, so the center of gravity is partial to easily left.
It two, the person jump up etc. action of since jump feet mostly left foot, the center of gravity inclines toward left foot, so turn left curved compare easily.
The foreign expert, who have, explain:The mankind's feet, or so and each have it the function, the left foot contain the support function(support center of gravity), the right foot contain the sport function.(control the direction and speed)Because the center of gravity is partial to in the left foot, so gather speed with the right foot 蹬 ground with
In 1912, at the moment that international farmland 联 establish unifies the direction for run a race to settle in order to take left hand as seamy side, then turn to the left curved, be juxtaposed into the farmland 联 rule, follow to use up to now
Still have this parlance
The track events of the in fact ancient Olympic sports games didn't round a turn to run, it was in the straight line runway to come up to return to something to run.And the track and field events of the modern age just started appear in England, similar to horse-racing with agreeable the clock direction to run, modern Olympics(1896) a beginning also with rightward clockwise run, arrive in 1912 international farmland path to rule to change suddenly to run for the negative hour hand direction after always willing establish, explain what reason.
Go to 於 , various games seem to be to all carry on with negative hour hand direction currently of reason, have some parlances for example the protection heart say,consistently use say,sport the feet say etc. the profusion of different opinions 莫衷 is on being the person's brain to divide or so two hemispheres, the or so function is different.The person's left brain controls a right and half-length activity, the right brain then controls a left and half-length activity.In the daily life, the most people develops to live,write in the right hand stem,the habit of the work, but the left brain mainly carries on a deluxe thinking activity again, so aggravated the burden of the left brain consumedly.The human body has to strengthen to be subjected to the left leg function that the right brain control for supporting the balance of the whole body, so the majority feel a left leg more emollient than right leg.While run a race, most athletes all use left leg as the empress 蹬 leg.BE emollient because of the left leg while run curved way, press negative hour hand direction to run, the left leg can overcome body nicely of leave mental exertion, avoid toward seamy side dump.The right leg strength is smaller than left leg, if press clockwise run, will feel body unsteady, fall down easily.Person while skate,ride bicycle to turn a corner with running, also have a same felling

Go to various games of 於 to seem to currently all with negative hour hand direction the reason that carry on, have some parlances for example protection the heart say, consistentlies use to say, sport the feet say etc. the profusion of different opinions 莫衷 is on is the person's brain about cent two hemisphere, the or so function is different.The person's left brain controls the right and half-length activity, the right brain then controls the left and half-length activity.In the daily life, the most people developped to live, write with the right hand stem, the habit of the work, but left brain again mainly is to carry on the deluxe thinking activity of, so aggravated the burden of the left brain consumedly.Human body for the sake of the balance of the maintenance whole body, must strengthen to be left leg function by the right brain domination, so the majority feel the left leg more emollient than right leg.While run a race, the 蹬 leg after most thletes all use the left leg conduct and actions of.While run curved way, is emollient because of the left leg, press negative the hour hand direction run, the left leg can overcome the body nicely of leave the mental exertion, avoid dumping toward seamy side.The right leg power is smaller than left leg, if press clockwise run, will feel the body unsteady, fall down easily.Person while skate, riding the bicycle to turn a corner and run, also have the same felling
