For rock climbing to reach a relative level, climbers must learn to use the strength of their legs and feet. The weight-bearing ability and explosive power of the legs and feet are much greater than the hands, and the endurance is strong. During the climbing process, the strength of the legs and feet must be fully utilized. There are only four places where a foot can touch a rock point: the front of the foot (used under the eaves); the medial edge of the toe (big toe); the lateral edge of the toe (the tip of the toe) and the heel tip (main It is used to hang feet when turning the eaves). When you step on the foot, the toes can only be stepped into the width of one finger, not too much. If you put the entire foot on it, if the foot does not use force, the weight of the whole body will be placed on the hand, and the arm will bear too much force, which is easy Fatigue and soreness; and it is easy to fall off when doing left and right movements, changing feet, turning and other actions.
"Foot change" is a basic climbing technique, which is often used in climbing. When many beginners change their feet, the front foot kicks hard, jumps up, and the rear foot steps on the point where the front foot steps. It looks very easy, but in fact this is wrong, because on the one hand, the power is transferred to the hand Increase the strength of the hand;
On the other hand, the body's center of gravity is unbalanced and it is easy to lose; more importantly, when the foot point is high, the distance between the hands and feet is short, and the flexibility requirements are very high. It is not possible to change feet with this method.
The correct method of changing feet should ensure that the body's center of gravity is stable and does not increase the burden on the hand. For example, to switch from the right foot to the left foot, first put the left foot above the right foot, the right foot is centered on the right side of the stepped point, and rotates counterclockwise from the inside to the right, leaving the inner left side of the point free , The weight is still on the right foot, the left foot is cut in from above, step on the point, the right foot must slide out, and the weight transitions to the left foot. The movements are used together, just like the soles of the feet are greased. The right foot slides out of the point and the left foot slides in at the same time. The weight is always borne by the feet. The hand is only used to adjust the balance. In the process of rock climbing, besides supporting your weight, your feet are often used to maintain your balance. The feet are not always stepped on the point, and it is not necessary to step on the point. Sometimes one foot is stretched out and the toe is clicked on the wall to adjust the position of the center of gravity of the body so that the center of gravity of the body falls to the other. On the feet, I call this: the three-point stability method (triangle stability).
