The effect of the seminar was very significant, focusing on the various issues accumulated during the week, including professionalism, service, institutional processes, etc., and even discussed the problems raised by members, such as the lack of indoor scenery and whether to add potted plants and fish tanks.

After solving all the problems, Ji Ke pulled all the coaches to the rehabilitation bed in the small equipment area, ready to show them the routine examination techniques of knee joint movement.

"No matter which part of the injury is assessed, or the injury is examined, we must first know what the function and function of the tissue structure that makes up this part is," Ji Ke asked Liu Shuai to lie on the rehabilitation bed and pointed to Liu Shuai's knee joint, "Let's only talk about the knee joint now." ”

The structure of the knee joint includes not only the two large bones of the thigh femur and the tibia of the lower leg, but also the patella, ligaments (anterior and posterior cruciate ligaments, medial and lateral collateral ligaments, transverse knee ligaments, patellar ligaments, etc.), meniscus, joint capsule, etc.

"We all know that the knee joint is an important joint of the lower limbs of the human body, not to mention the complex structure, it is more likely to be injured than other joints, so its injury examination technique must be mastered, well, its injury examination is included in the list of skills that must be mastered by coaches above the first level, and coaches below the first level are not required to master, but they must be understood, at least to say one, two, three!"

The list of coaching skills is a policy that Ji Ke and Gu Yu have come up with and are going to announce in the next competition, trying to make members more intuitive to quantify the level of coaching, which is also an important means for them to improve the quality of the game.

As the organizer of the competition, the core formulator of the skill list, Ji Ke took the lead in practicing in the gold medal personal training, which can be regarded as collecting market reactions; overall, the effect is good, at least the printed skill list explanation manual sample was almost torn up and taken away by the members.

As soon as Ji Ke said this, Liu Shuai, who was lying on the bed, and the coach standing next to him had a discussion, Nima, you are a self-proclaimed referee-level coach, and you are so deliberately embarrassed for others, is this really good? With this, the new skills of the first-level coach have exceeded twenty!

"First of all, I will give you an overview of the patella assessment techniques and conclusions. Ji Ke motioned for Liu Shuai to straighten his legs, relaxed, put one hand on the patella of one of Liu Shuai's legs, and gently pushed the patella to slide towards the calf with the other hand.

"This is mainly used to detect patellar grinding, which is patellar wear, and if a member feels pain in the process of contracting the quadriceps, it means that his patella is worn. Ji Ke instructed Liu Shuai to cooperate with him while explaining.

The main culprit of patellar wear and tear is the strength of the quadriceps muscles.

The quadriceps muscles are composed of four muscles: vastus medialis, vastus lateralis, rectus femoris, and vastus medius.

Due to the need for exercise and weight-bearing, the pressure on the knee joint is very huge, resulting in the ossification of the quadriceps tendon in the knee joint, so everyone has the largest sesamoid bone in the human body: the patella, which is used to share the pressure of the quadriceps tendon and prevent the tendon from wearing.

When the quadriceps muscle is too tense for a long time, the patella will be squeezed upward by its tendons, and the femur, the largest long bone in the human body, will rub against it;

Although the patella has the word bone on its name, it is actually made of ossification of the tendon, which is less dense than the real bone, and in long-term friction, the patella will be partially ground off by the femur, and if it is worn too much, it will feel pain.

In daily life, frequent wrong leg raises (Note 1) generally strengthen the quadriceps muscles, and as we age, the relatively strong quadriceps muscles will pull the patella to rub against the femur, which is the main reason for knee pain in older people.

"After determining the wear and tear of the patella, as a fitness coach, the only thing I can do is to help the member solve the problem from the root, that is, to release the quadriceps!" Ji Ke put his hand above the knee joint, "The quadriceps muscle area is large, if you want to achieve immediate results, you must release it in a targeted manner." ”

Specifically, patellar wear is mainly caused by the quadriceps insertion, that is, the quadriceps muscle near the knee joint is caused by the quadriceps muscle pulling the patella, and the release should start from the patella, along the vastus medialis, vastus lateralis muscle, and rectus femoris (the femoris medius muscle overlaps and is located below) one by one with the thumb or heel to gently loosen it.

"You must be gentle when you loosen, and remember to emphasize this when training new coaches in the future!" Ji Ke warned his friends very seriously.

The force of the release is a concrete reflection of the professionalism of the coach, and it has a significant impact on the member's experience in the studio/gym!

The coach directly pressed and rubbed vigorously when he was released, and the members cried in pain and did not say anything, and they would also reject the coach and the studio/gym in their hearts;

When a member doesn't come to the gym/studio because the coach is too strong when he is relieved, he usually can't come because he is busy with work, has a lot of family affairs, etc., and he won't say that it is because the coach has too much strength when he is relieved, which makes me feel scared, and then the studio/gym will see that this member is busy 365 days a year!

"There's nothing wrong with patellar grinding, right?" Ji Ke paused slightly, and seeing that no one asked, he continued, "I'll add another corroborative technique: patellar light pressure!"

Patellar light compression, in which the palm of the hand is gently pressed vertically on the patella, is used to test whether the knee pain is coming from a fat pad under the patella!

In addition to storing energy and keeping warm, fat in the human body also has an important function of cushioning and shock absorption.

The difference is that patellar wear is a long-term injury, while fat pads are caused by strenuous leg movements, such as suddenly straightening your legs when playing basketball, touching your knees when jumping, etc.

Drastic pressure changes can cause the fat pad under the patella to become thin and lose its cushioning function as if it had been smashed by a sledgehammer.

"Gently press the patella with the palm of your hand, if the member feels pain, it means that he has a patellar fat pad injury, and if he has not recently done strenuous leg exercises, you can pluck the member's peripatella, quadriceps tendon attachment points, and patellar ligament for simple maintenance;"

Ji Ke did not bring out other complicated things that were difficult to master, such as acupuncture, acupressure, and so on.

"If the member reports that his knee joint hurts repeatedly, depending on the situation, whether to tell me, or suggest that they go to the hospital for a check-up," Ji Ke vaguely reminded his friends, if the consumption potential is not high and the grasp is not large, don't push me here, let them go to the hospital first, and then say.
