在田径比赛的竞赛项目中,凡200米以上的项目,运动员都是向左转弯(逆时针方向),这是为什么呢?原因有以下两条:
其一,人的心脏位于身体左侧,所以重心容易偏左。
其二,人的跳跃等动作的起跳脚多是左脚,因为重心偏向左脚,所以向左转弯较容易。
有的外国专家解释:人类的脚,左右各有其作用,左脚起支持作用(支持重心),右脚起运动作用(掌握方向和速度)。因重心偏于左脚,所以用右脚蹬地面来增加速度与
1912年,国际田联成立之际,把赛跑的方向统一定为以左手为内侧,即左转弯,并列入田联规则,沿用至今
还有这个说法的
其实古代奥林匹克运动会的径赛并没有绕圈跑,它是在直线跑道上来回跑的。而近代的田径比赛刚开始出现在英国,与赛马一样是以顺时钟方向来跑,近代奥运(1896)一开始也是以向右的顺时针方向跑,到了1912年国际田径总会成立后突然规定更改为逆时针方向跑,并没有解释啥原因。
至於各项比赛目前似乎都以逆时针方向来进行的原因,有一些说法例如保护心脏说、惯用手说、运动脚说等众说纷纭莫衷一是 人的大脑分左右两个半球,左右的功能不一样。人的左脑支配右半身的活动,右脑则支配左半身的活动。在日常生活中,大多数人养成了用右手干活、写字、工作的习惯,而左脑又主要是进行高级思维活动的,因此大大加重了左脑的负担。人体为了维护全身的平衡,必须加强受右脑支配的左腿功能,所以多数人感到左腿比右腿有力。赛跑时,多数运动员都是用左腿作为后蹬腿的。在跑弯道时,由于左腿有力,按逆时针方向跑,左腿就能很好地克服身体的离心力,避免向内侧倾倒。右腿力量比左腿小,如果按顺时针方向跑,就会感到身体不稳,容易摔倒。人在滑冰、骑自行车拐弯和跑步时,也有同样感觉

At in the track and field competition competition project, every 200 meter above project, the athletes all are the left face are curved (counter clockwise), why is this? The reason has following two:
First, human's heart is located left side of the body, therefore the center of gravity is easy to xxxx left.
Second, the human jumps and so on the movement stamps one's foot many is a left leg, because of center of gravity deviation left leg, therefore the left face curved is easy.
Some foreign experts explained that, Humanity's foot, about has its role respectively, the left leg plays the support role (support center of gravity), the right crus of diaphragm play the movement function (to control direction and speed). Because the center of gravity in favors of the left leg, therefore increases the speed with the right foot pedal ground and
Time 1912, International track and field meet federation
had been established, decides as the race direction unification take the left hand as the inside, namely turns left, and includes the field association rule, continues to use until now
Also has this view
Actually ancient times the Olympics games track athletics has not gone around runs, it is back and forth runs on the straight line runway. But the modern track and field competition just started to appear in England, was equally by is suitable the clockwise with the horse racing to run, modern Olympic Games (1,896) from the very beginning also are by to are right clockwise run, the international track and field general meeting had been established after in 1912 stipulated suddenly the change ran for the counter clockwise, what hasn't explained reason.
As for each competition at present as if all the reason which carries on by the counter clockwise, some some views for example protect the heart to say, habitually using said, the movement foot said and so on has wide divided opinions about the unable to agree person's cerebrum minute two hemispheres, the about function is dissimilar. Human's left brain controls the right half-length activity, the right brain then controls the left half-length activity. In the daily life, the majority person fostered has worked with the right hand, writes, the work custom, but the left brain mainly carries on the senior thinking activity, therefore aggravated the left brain burden greatly. The human body in order to maintain the whole body the balance, must strengthen the left leg function which is controlled the right brain, therefore the most people felt the left leg is more powerful than the right leg. When race, the most athletes all are after the left leg took stretches the legs. When runs the curve, because the left leg is powerful, runs according to the counter clockwise, the left leg can overcome bodily well the centrifugal force, avoids falling to the inside. Right leg strength compared to left leg small, if according to clockwise runs, will feel the body is not steady, is easy to throw down. The human when the ice-skating, rides the bicycle corner and jogs, also has the similar feeling
看看这个行不行?呵呵.........

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), why this is?The reason contain two followings:
It a, 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 jumps up etc. action of since jump the feet mostly left foot, the center of gravity inclines toward the 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 rises to support the function( support center of gravity), the right foot rises the sport function.( control the direction and speeds)The center of gravity is be partial to in left foot, so gather speed with the right foot 蹬 ground with
In 1912, at the moment that international farmland 联 establish, unified the direction that run a race to settle in order to take left hand as the 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 of
The track events of the in fact ancient and Olympic sports games did not round the turn to run, it come up to return to something to run in the straight line runway.And the track and field events of the modern age just starts appear in England, similar to horse-racing with agreeable the clock direction to run, the modern Olympics(1896) is on start also with rightwards clockwise run, arrive the international farmland path of 1912 total will establish after rule to change suddenly to run for the negative hour hand direction, did not explain what reason.
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

In track and field competition sports, where more than 200 metres project athletes are left to the (anti), which is why? The following two reasons : First, the people at the heart of the physical side, the focus easy course. Second, the leap, the moves are a perfect left foot, because the focus towards left foot, so to bend more easily. Some foreign experts explained : human feet, or have their role left foot supportive (support center), the right of movement role (master direction and speed). Focus too left foot as a result, the right feet in the ground to increase speed and 1912, the council on the occasion of the establishment of the unified direction for the race to the left hand to roll, bend, and in the Tian rules adopted so far This is also the In fact, the ancient Olympic Games track and not getting run, it is run in the back straight on the runway. And the beginning of modern athletics competitions appeared in the United Kingdom, and as a horse to run Shun clock direction, modern Olympic Games (1896) is also beginning to hit the clockwise direction run to the 1912 establishment of the International Athletic Association regulations suddenly changed to run clockwise, and did not explain what reasons. As for the competition now seems to have anti reasons, such as protection of the heart that some say, the usual hand said, the campaign said such views among the feet brain about two hours hemisphere, or not functional. The left brain dominance right passport activities, the right brain is dominant left passport. In daily life, most people develop a work with the right hand, write, work habits, and also mainly senior left brain thinking activities, and therefore greatly increase the burden left brain. To safeguard the human body balanced by the need to strengthen the functions of the right brain dominance in the left leg, the majority of people feel left leg over the right leg strong. Race, most athletes are used as a left leg after Dengtui. Maybe in the run, as a strong left leg, according to anti Run, the left leg will be able to overcome their physical well centrifugal force, to the left to avoid dumping. Small left leg right leg strength than if run by clockwise direction, it will feel physically unstable, easily injure themselves. In skating, riding a bicycle turn a corner and running, it is the same feeling
