Recently, some martial artists have mentioned to me that they have knee pain when standing on piles and practicing boxing, and some friends even have unbearable pain. How can such a phenomenon occur? Some friends said that it was caused by standing on the pile for too long, and some friends said that it was not enough to relax.
In fact, this understanding is not correct. If it is caused by the long time of standing on the pile, then why do the older generation of boxers put a lot of effort into standing on the pile? Aren't they afraid to break their knees? Why am I saying that "loose is not enough" is also incorrect? Because the lower limbs of the human body itself have to bear the weight of the human body, especially the knee joint, which is a joint with the largest load and the largest amount of activity among all the joints in the human body, therefore, it is necessary to completely relax the knee joint, unless the feet are not stained in the bed.
So, what can be done to not hurt the knee joint, but also to work hard? The answer lies in the "eight-character twenty-four methods" that are regarded as the guideline by the shape and meaning boxing, in which the correct essentials of the knee joint account for the four curves, tops, buckles, and straights in the "eight characters". In the "Four Classics of Internal Strength", there is a very clear statement on the essentials of the knee joint: in the "format chapter" of the "Internal Gong Jing", the requirement for the knee is "knee bent and extended"; In the "Strength Recipe", it is mentioned that "forcing the buttocks to strengthen the knee"; In the Nagua Sutra, it is even clearer: "Whenever you use a step, the two outer tiger eyes strive to go inward, the two inner tiger eyes try to go outward, the big tendons in the committee try to straighten, the two caps are bent with all their strength, the four sides intersect and merge the power of the surrounding body, and when they twist outward, the spring qi can be exuded." ”
Bending both knees can make the lower limbs strong, deep-rooted, and increase the bottom work. However, it should be noted that if it is too bent, it will not be enough, which will make the energy hold in the crotch and not reach the soles of the feet; If it is too straight and will cause exhaustion, the leg pedaling strength will be insufficient when moving and become a single strength, so the knee must be composed in the song to seek straight, like curved and not curved, like straight not straight, so "martial arts" advocate Li Xiankang according to "Sports Biomechanics" clearly proposed that the angle of the knee joint in the pile is 135 degrees as the best state.
However, it is not enough to bend the knee joint. When standing on the pile and dynamic, the knee joint must be forced, at this time, the correct force habit is the key to practicing good shape and meaning boxing. After making the correct angle of bending, the knee joint will produce forward and downward force, if there is no relative force balance, then it will cause the force to be completely concentrated on the knee, so that for a long time due to the local force of the knee joint is too much, it is bound to cause qi and blood to accumulate here, which is why many friends practice boxing after the knee joint is painful. The correct essentials, as mentioned earlier, the song still requires straightness, how to make this? In fact, there is a very key point that the kneecap, that is, the patella, must be "sucked" inward and upward.
