The breaststroke is actually very simple

Today to introduce the breaststroke, arm exercise, I hope everyone can learn to swim out early," rock" era.

Breaststroke arms in depth analysis

In 1, the starting position:

Arms keep certain tension natural move straight, parallel to the water surface, the body into a straight line.

2, grasping water:

Previously extended arm, shoulder abridged pronation, two palm slightly to the diagonal below, slightly hooked wrist, both hands apart diagonally downward pressure water.

In 3, thrash:

The arms are divided into 40-45 degrees, wrist began to bend, and two hands to the side, gradually active, under rear bent arm stroke. In rowing, forearm and upper arm flexion angle, is constantly changing, generally excellent athletes rowing main stage joint Qu Cheng near 90 degrees c.. Because of this angle to maximize the strength, at the same time to make good use of the chest and back of large muscle groups. The general low level athletes elbow angle is large stroke, the paddle arm to arm angle of about 120 degree angle, which should be a continuous transition to do hand movements, stroke and close at hand, hand walking route should not to the shoulder of the lower rear, should be in front of the shoulder. In order to make full use of all the forward force to improve the speed, before entering the water, athletes should be to larger forces do stroke, to get ahead of the most high speed. Therefore, athlete in rowing, body position rises higher, this is unreasonable the phenomenon.

4, close at hand:

Hand pull phase is continuing, hand process also can produce a larger forward force and lifting force. The arms to receive upward in front, below, when the arm and elbow almost at the same time to do action, hand should not reduce stroke velocity, but faster to perform. Hand, should not emphasize two elbow to clamping action, it will weaken the pull force. At the same time, also should avoid excessive water line. Hand movements should be conducive to do a quick hand forward motion, without affecting the arm leg movement coordination. When the hand close to the front side, two palm is turned back toward the inside, upward, then the big arm should not exceed two shoulder extension line is appropriate in the entire hand movement process, hand movements should be aggressive, fast, smooth to finish at the end, hand, elbow below hand, arm size at an acute angle.

In 5, arm:

As can be seen from the action, arm is composed of elbow extension, shoulder to complete. Palm upward gradually by

Steering force, at the same time to move out. Fast reaching movements is one of the characteristics of the modern breaststroke technique, it closely with legs

Action, therefore in the arm at the same time, the shoulder to move. Many athletes also almost at the same time "pressure",

But attention must be paid to forward reaching movements can be stopped phenomenon.

In short, the entire arm moving route, either overlooking or looking up is elliptical.
