The gluteus medius muscle belongs to the superficial muscle like the gluteus maximus muscle mentioned yesterday, and the deep muscle belongs to the deep muscle. Deep muscles also have some joint movement functions, and a more important function is to be responsible for stability and protection. Well, stability is very important. Let's see:
Musculus gluteus medius:
The gluteus medius is located in the gluteus maximus, starting from the lateral iliac wing and ending in the greater trochanter of femur. If you don't know the location, please look at the picture. Its relationship with gluteus minimus is better than that with gluteus maximus. Although the gluteus medius belongs to superficial muscle, it is also called superficial muscle, but its function is with gluteus minimus, so we will talk about their functions together later.
The quadratus femoris is also covered by the gluteus maximus. It is conceivable that the starting point is the ischial tubercle and the end point is the intertrochanteric ridge of femur. Together with the two brothers of the obturator internus, it is mainly to make the thigh externally rotate (also called external rotation) at the hip joint.
Gluteus minimus:
The medial gluteus medius is gluteus minimus. The starting point is the bone surface below the hip and above the acetabulum. I understand that the starting point of gluteus minimus is slightly lower than that of gluteus medius, and the stopping point is the greater trochanter of femur, which is the same as that of gluteus medius. The starting point is similar and the ending point is the same, which makes them have similar functions. Irresponsibly speaking, the two are a virtue.
By the way, you can touch the greater trochanter of femur with your hand, almost in the pocket position sewn on the middle pants. My legs are short, so my pants are raised high. If you touch it, you can feel the bones. If you can't touch it, then you don't have pants without pockets, and it's time to lose weight.
The gluteus medius and gluteus minimus have the same function. When near fixation, do thigh abduction at the hip joint, that is, lift the leg sideways. Then they have four functions: thigh flexion and extension, hip external rotation and internal rotation. When I first saw this, my heart was calm. I just want to tear up the autopsy book. I endure it because the gluteus maximus can abduct and adducte, because it is large and has a large span, and the upper and lower muscle bundles can have relative functions. This is understandable, but what are the gluteus medius and gluteus minimus? Can you be flexible, man? ! !
Look at the picture:
According to the anatomy book, the front of the two muscles can make the thigh bend and pronate (pronate) at the hip joint, and the back of the two muscles can make the thigh stretch and pronate at the hip joint. What do you mean, when your thigh is lifted forward (hip flexion), the hip twin from the iliac wing to the greater trochanter of femur is lifted forward. At this time, the hip joint is flexed, and then when you rotate the hip joint inward (pronation), both brothers will participate in the stress.
Your legs are sticking back. Remember the scorpion leg? At this time, the thigh stretches and rotates outward (outward rotation) at the hip joint, and the two brothers also participate in the stress.
What needs to be explained to you is that when the hip joint is abduction and adduction, the gluteus maximus is a reluctant antagonistic muscle, which is inaccurate. I'm not responsible anyway. It is not contradictory for gluteus maximus to hit itself, because it is big and occasionally there will be civil war.
But! The functions of the gluteus medius and gluteus minimus are two states, and they are not opposite to each other. This is not a contradiction. We have to find out. If you don't understand, don't worry. You're not a fitness instructor. Why do you know so much? What? You're a coach? Then you don't even know this thing! !
Continue to look at the picture:
Look at this growing flower of the motherland. I have a pair of pants like this. that this is not the important question. His front thigh (right leg) flexes at the hip joint, and his rear leg (left leg) stretches at the hip joint. At this time, the right gluteus medius and gluteus minimus hip flexion, the left gluteus medius and gluteus minimus hip extension. Can you say that it is a muscle that is opposite to yourself? Don't! ! ! One is the left buttock and the other is the right buttock! Can you understand this?
What? You knew from the beginning? How about you play with me?
The lateral obturator muscle is located in front of the quadratus femoris, starting from the lateral obturator fascia and the surrounding bone surface and ending in the femoral trochanteric fossa.
The obturator internus muscle is located in the medial wall of the small pelvis, starting from the medial surface of the obturator fascia and the surrounding bone surface and ending in the femoral trochanteric fossa.
The main function of these two brothers is to make the thighs rotate outward at the hip joint when they are close to fixation.
Ilipsoas muscle:
Ilipsoas muscle is a combination, which consists of iliopsoas muscle and psoas major muscle. It's quite red, but you just don't know it. If you are a girl, you should know it very well. It is located on both sides of the lumbar spine and inside the pelvis.
Iliac muscle originates from iliac fossa, and psoas major originates from the lateral surface and transverse process of thoracic vertebra 12 and lumbar vertebra 1 ~ 5. * * * Stop at the femoral trochanter.
Function: When approaching fixation, bend the thigh and rotate outward at the hip joint. When the distal end is fixed, one side contracts to bend the trunk sideways, and both sides contract at the same time to bend the trunk forward and the pelvis forward.
I want to tell you something about the function of iliopsoas muscle and trunk flexion when it is far fixed. Please think about it. What is the most commonly used function of trunk flexion? Did you come out? The one who said bow, get out!
When you tuck in, your torso bends forward. Please remember that this is a Yi Labao. Do not do sit-ups. I have seen many cases in the gym, that is, lying flat on the mat when rolling up. If you press your legs, it is easy to make a dozen or twenty. If you let go, it is difficult to achieve three. Why?
Who did you press when you were in leg press? If you press the thigh, you press the femur, and the iliopsoas stops at the femoral trochanter, is the iliopsoas fixed at the distal end? Is it hard to practice abdomen? But do you feel anything in your abdomen? A friend over there asked, what should I do if I press my calf? Your thighs and calves are separate? Because of pressing the calf, the front side of the thigh is tense when abdomen is closed.
Stop at how to do it. Let's start with abdominal muscle training. Ha ha ha, that's what I am. Come and hit me.
Oh, dear! It hurts! !
Let's talk about piriformis:
The piriformis muscle is located in the posterior wall of the small pelvis, starting from the lateral side of the presacral foramen in front of the sacrum. Stop point: greater trochanter of femur. Function: Proximal fixation makes the thigh rotate and abduct at the hip joint. When far fixed, both sides contract at the same time, making the pelvis backward. Haha, it's said that the pelvis is backward again.
Speaking of piriformis, we have to say piriformis syndrome, which is the content of sports rehabilitation. Now let's take a look at it first, and insert a Baidu entry below:
Piriformis syndrome is a common disease, which can cause acute and chronic sciatica. It is generally believed that the high branch of common peroneal nerve passes through piriformis muscle bundle or sciatic nerve passes through piriformis muscle abdomen. When piriformis muscle is injured, congestion, edema, spasm, adhesion and contracture occur, and the muscle space or the upper and lower holes of muscle become narrower, squeezing the nerves and blood vessels passing through it, so a series of clinical symptoms and somatic symptoms are called piriformis muscle injury syndrome.
The position of piriformis muscle is awkward, because many nerves and blood vessels pass through it, and some pass through its abdomen. If KI expands, you'd better ignore it and ignore me. However, if the security guard at the entrance of your community is inflatable, you will be stuck every time you go in and out. Will it be inconvenient for you to go in and out, so the location is very important.
Why is the piriformis "swollen"?
In fact, people still don't exercise and stretch often. People are like machines, they will rust if they are not used for a long time. Healthy muscles are soft and elastic. At this time, your blood circulation and nerve conduction are completely fine, plus regular exercise and stretching, it will only be better. But unhealthy muscles are stiff and don't exercise, so I ask you, if you write all day, will your shoulders be tight or even hard at the end of the night, and will your arms and legs be numb if you don't move for a long time? This is caused by muscle tension.
The piriformis will harden when it is tense. Before you entered the community, the security guard smiled at you, and you nodded to each other and went in. But now the security guard insists on checking your access card, and his attitude is not good. Are you slow to enter the door? The metaphor is not appropriate, just pay attention to the spirit.
If this happens, it is obvious that the nerve is numb, because the place where the nerve is numb is not a point, but a piece of nerve. My suggestion is to go to the hospital first, and then find a professional coach to help you if you need exercise rehabilitation. Because rehabilitation involves too much, I can only tell you in detail in the future. If you have a problem now, you can call me!
I'm not asking everyone to come to me for practice. Well, I'm in Beijing. Bah! I want to tell you, when you can't decide whether to exercise by yourself or find a coach, how can you tell the difference between a coach and a coach? Then you can trust me personally. Maybe I can give you some advice.
Attention, everyone! Let's enter welfare time. If you insist on seeing this place, KI, as an old driver, will give you benefits. Speaking of pelvic floor muscles, you may not know much about it:
You don't need to know every muscle in the pelvic floor muscle group in fitness. Pelvic floor muscles are important for both men and women. Why is it "for both men and women"? You know ...
Women, especially postpartum women, will have very, very embarrassing things if they don't recover well. That's a leak! Hey hey hey! Those who don't swipe their cards on the bus will wait and see for a while.
Here is a brief introduction, and there will be special articles in the future if necessary. Postpartum women are special, because after giving birth, you expose all your hidden physical problems, or your mother is great.
During pregnancy, your pubic symphysis will relax slowly because of the role of pubic relaxant, which is convenient for opening during delivery and muscles will become relaxed. Even if you have a caesarean section, it will be affected and the pelvic floor muscles will relax. If the postpartum recovery is not good, it will leak urine. This is just a point, not to mention the core of the abdomen.
One more thing, driving feels that the road is wider. I don't mean to disrespect women at all. For everyone to see, I hope everyone understands. This is caused by incomplete pelvic closure and muscle relaxation, and some of them have incisions ... with a ratio of 3: 1, the pelvis is tightened by three centimeters, and the road is tightened by one centimeter. Experience it for yourself.
Don't those who haven't been born need training? In fact, sports cannot be changed overnight, and it needs long-term accumulation. Why do some people recover quickly after giving birth to children, and some people have many problems? Even if you don't have children, then you can't drive? Look at the following paragraph about PC muscle, especially the last sentence. Don't you want to have a good figure even if you don't drive?
There are still many problems, and I really can't expand them. I tried my best. We'll talk about it later if necessary.
The following boy welfare time, what? That's boy welfare? Have you passengers fastened your seat belts? The following are the welfare hours for girls:
How many boys don't know PC muscle now? Hands Up! Everyone, especially girls, don't ask for people who raise their hands.
The PC muscle is actually the pubococcygeus muscle. It can support pelvic organs and maintain the tension of soft tissue in Y part. The strength and elasticity of PC muscle are very important to ensure women's smooth delivery and enhance women's reaction ability and urinary system function when driving.
