侧泳几种游法？英文双语对照

两种，手出水和手不出水两种技术。

侧泳是身体侧卧在水中，用两臂交替划水，两腿做剪水的动作游进。侧泳的方法有很多，大致分为手出水和手不出水两种技术。侧泳具有较大的实用价值，在持物游渡江河或救护溺者时经常使用。

侧泳技术动作特点

1、身体姿势

身体侧卧水中，稍向胸侧倾斜，头的侧下部浸入水中（近似于爬泳的吸气动作），下面的臂前伸，上面的臂置于体侧，两腿并拢伸直，游进时身体饶纵轴转动。

2、腿部运动

腿部动作分为收腿、翻脚和蹬剪腿三部分。

①收腿：上腿向前收，下腿向后收，注意尽量少收大腿，特别是下面的腿，大腿几乎不动。

②翻脚：收腿后，上腿勾脚尖以脚掌向后对准水；下腿将脚尖绷直，以脚背和小腿前面向后对准水。

③蹬剪腿：上腿用大腿带动小腿稍向前伸，以脚掌对准前侧后加速蹬夹水；下腿以脚背和小腿对准侧后方伸膝踢水，与上腿形成剪水的动作。

3、臂部动作

①上臂动作：上臂经空中（或在水中接近水面）往前移至头的前方入水，入水后前伸下滑高肘抱水，是手和前臂对准水，然后沿着身体去臂加速用力向后划水至大腿外侧，其动做基本与爬泳臂划水相似。

②下臂动作：下臂在身体下部前伸抱水，屈臂划水至腹部下方，掌心向上，以小臂带动大臂，沿身体向前做边伸边外旋的动作，伸直时掌心向下。

③两臂配合动作：下臂开始划水，上臂前移；上臂开始划水时，下臂开始做前伸动作，并稍做短暂的滑行，两臂在胸前夹叉。

4、完整配合

①臂和腿：上臂入水下臂前伸时，收腿；当划至腹下时，腿用力向后蹬剪水。

②臂、腿和呼吸：侧泳的呼吸和爬泳的呼吸基本相似，只是勿需把头埋入水中呼气。上臂推水和出水时吸气，并且头部也少有转动，移臂时还原，做憋气和呼气。为了保证呼吸舒畅，一般是一次腿、两臂各做一次划水、呼吸一次。

侧泳注意事项

1、身体位置

游侧泳时身体侧卧在水中，上臂自然置于体侧，下臂前伸，整个身体展成一条直线。胸腹面与水平面接近垂直，半面头和脸部露出水面。游进过程中，上臂入水时，上体和脸部稍稍转成侧俯卧，随着上臂划水再回转成侧卧委势。

2、腿的动作

侧泳腿的动作类似蛙泳，腿是产生推动身体前进的重要力量。但由于身体成侧卧委势，动作不对称，同蛙泳腿的动作有许多不同的特点，可分上腿和下腿进行分析

Two kinds, the hand goes water and hand not to give water two kinds of technologies.

Sidestroke is body side lies in water, with two arms alternant thrash, two legs do the movement that cuts water to swim into. The method of sidestroke has a lot of, divide roughly give water and hand not to give water for the hand two kinds of technologies. Sidestroke has greater economic value, in hold content to swim often use when the person that cross Jiang He or be addicted to of relieve a sick or injured person.

Characteristic of sidestroke technology movement

1, body pose

Body side lies in water, tilt to pectoral side a bit, in the side bottom water intrusion of the head (insult a movement at the suction of the crawl approximately) , the brachial extension forward below, the side of brachial park body above, two legs and approach unbend, x-axis of forgive of the body when You Jin is rotational.

2, leg ministry moves

Cent of leg department action is receive a leg, turn over foot and pedal to cut a leg 3 parts.

① receives a leg: The leg closes ahead on, next legs close backward, the attention receives ham less as far as possible, especially the leg below, ham is moved scarcely.

② searchs a base: After receiving a leg, the leg ticks off tiptoe to aim water backward with sole on; Next legs stretch tight tiptoe straight, with water is being aimed backward before instep and crus.

③ pedal cuts a leg: The leg drives crus to be extended ahead a bit with ham on, place water with pedal is being quickened after the side before sole is aimed; Next legs aim side with instep and crus rear extend genu to kick water, with on the leg forms the movement that cuts water.

3, brachial department action

Movement of ① the upper arm: In sky of classics of the upper arm (or surface is neared in water) enter water to the ahead of the head toward reach, the extension forward after entering water glides tall ancon holds water in the arms, it is hand and antebrachium alignment water, go along the body next the arm exerts oneself to do sth. quickly backward thrash comes the side outside ham, its are moved do basic as similar as thrash of the crawl arm.

② leaves brachial action: Next arms hold water in the arms in body bottom extension forward, the thrash that bend an arm falls to abdomen square, the centre of the palm up, drive big arm with small arm, edge body does an edge to extend the action of edge outward turning ahead, the centre of the palm when unbend is down.

Two arms of ③ coordinate an action: Next arms begin thrash, reach of the upper arm; When the upper arm begins thrash, next arms begin to make extension forward motion, do a bit glide momently, two arms place fork before the bosom.

4, complete cooperate

① arm and leg: When the upper arm enters underwater arm extension forward, receive a leg; Should delimit when falling to the abdomen, the leg toes step on backward forcibly cut water.

② arm, leg and breath: The breathing essentially similar of the breath of sidestroke and the crawl, in just needing gangmaster embedded water expiratory. The upper arm is pushed water and when giving water inspiratory, and the head is rare also and rotational, move when the arm reductive, do choke with resentment and expiratory. To make sure breath is free from worry, it is leg, two arms do thrash, breath each commonly.

Sidestroke note

1, body position

Swim side of the body when sidestroke lies in water, side of body of park of nature of the upper arm, issue brachial extension forward, whole body exhibits linear. Pectoral n and horizontal are adjacent and perpendicular, half head and facial ministry show water. In swimming into the process, when the upper arm enters water, the upper part of the body turn into side Fu to lie with facial ministry in a way, turn into side to lie as farewell of thrash of the upper arm appoint situation.

2, the movement of the leg

The action of sidestroke leg is similar breaststroke, the leg is the fundamental strength that generation drives the body to advance. But lie into side as a result of the body appoint situation, behavioral asymmetry, the movement that is the same as breaststroke leg has a lot of different characteristics, but the leg on cent undertakes an analysis with next legs
