一、犁式直滑降技术的含义

犁式直滑降习惯上称为犁式制动滑降，是双雪板立起内刃并呈犁状板型与滚落线方向一致的滑降。

二、犁式直滑降的应用范围

1．犁式直滑降是高山滑雪的典型基础技术，必须得以应有的重视。

2．用于初级阶段的减速及停止。

3．体验板尾推出、滑行中用刃及维持平衡感觉。

4．提高滑行速度、方向的控制能力。

5．为学习犁式回转创造条件。

三、犁式直滑降的动作要领

1．在一个能立住的缓坡上呈滑雪基本姿势，在下滑过程中躯体和手臂保持不变。

2．以双板前尖为假想圆心，双雪板为半径，双足拇趾跟部球状处为力点，双腿跟同时向外展转，将双雪板后部同时边推开边立内刃，板型呈犁状，板尖相距仍约10公分，双膝稍屈并略有内扣，双腿与雪面几乎成等腰三角形。

3．双雪板呈犁式后靠，双脚内侧均等用力滑行，大、中、小犁式变化时靠双足拇趾跟部为力点展转。

4．重心位于两板中间，体态的左右外型、双腿的用力多少、双雪板立刃程度、双雪板尾向外展转的大小均应对称，参见图32。

5．上体放松，目视前方雪面。

6．犁式滑降前后的重心位置，根据速度、坡度、雪质、用途的不同，随时应做相应的移动。

7．犁式滑行中除调整犁式的大小外，还可通过肌肉的内力对雪板刃施力的大小及立刃的强弱进行调整，达到控制速度，维持平衡的目的。

四、犁式直滑降的练习方法

1．首先以小犁式在速度低、坡度缓的场地上练习，逐渐提高滑行难度。

2．与双板平等直滑降结合练习。

3．将大、中、小犁式板型结合练习，参见图35。

4．改变立刃大小的反复练习。

5．改变用力大小的反复练习。

6．直滑降后用犁式滑行减速与停止的练习。

7．在不同坡度和雪面有凹凸的场地上的练习。

五、犁式直滑降的注意事项

1．始终保持住犁式滑降的基本姿势及左右的对称。

2．弯腰大，不顶膝、大扣膝、后坐、立不住板刃、控制不住犁式板型都是常见的错误。

I learn with double plate plough type technology skiing

A, ploughs type straight glide technology meaning

Plough type straight downhill habit is called plough type brake glide, is set up double skis within and with the blade plough shape plate type and rolling line direction of glide.

Second, plough type straight downhill applications

1. Plough type straight downhill is typical of the alpine skiing based technology, must be due attention.

2. Used in the primary stage of the deceleration and stop.

3. The launch, slide board experience with blade and maintain a balance feeling.

4. Improve your taxiing, direction control ability.

5. In order to study the plough slewing create conditions.

Three, ploughs type straight downhill behavioral essentials

1. In a can stand up together on the gentle slope of the basic position in a skiing, in the process of the body and arms down remain unchanged.

2. The board before pointed right, for imaginary double skis for radius, foot to toe the ball with thumb in point, do with the legs simultaneously to came, will double the skis back side at the same time within blade, push away made plate type shape, the board is the plough pointed still about 10 cm apart, knees slightly bend and within a button, with snow surface almost into legs an isosceles triangle.

3. Double skis plough type on the feet, after the taxi, equal force large, medium and small plough type change when rely on foot to do some of the toe-came.

4. The center of gravity is located in the middle of the two board, posture around the legs shape, how much force, double skis degree, double end came to the skis are to be the size of the symmetrical, see figure 32.

5. Body relax, visual ahead of snow,.

6. Plough type of center of gravity, before and after glide according to speed, slope, those, different purposes of, at any time should do the corresponding move.

7. Taxi in addition to plough type adjustment of the size of the plough, still can use muscles to edge of internal force of the blade of the size of the force and made the strength of the blade adjustment, to control speed, maintain the balance of purpose.

Four, ploughs type straight downhill practice method

1. First in small plough in low speed, slope of slow on the site of the practice, gradually improving taxi difficulty.

2. Double plate with equal straight downhill combined with practice.

3. Will be large, medium and small plough type plate type combined with practice, see figure 35.

4. Change the size of the practice made blade.

5. Change the size of the force practice repeatedly.

6. Straight downhill slide after plough type with slow and stop of practice.

7. In different slope and snow, a bump on the site of the practice.

Five, the plough type straight downhill precautions

1. Always keep the plough the basic position of glide around and symmetrical.

2. Bend over big, not top knee, big buckle the knee, the back, not stand board blade, couldn't control plough type plate type are common mistakes.
