The thing is, a Ms. Wu from Shanghai is 160 cm tall and weighs 93 kg. Recently, she wants to lose weight to 88 Jin. She chose skipping rope, skipping rope 4000 times a day, and her knee hurt for a month. After going to the hospital for examination, I found ligaments and meniscus tear, and needed surgery. Moreover, Ms. Wu's meniscus is deformed and not suitable for strenuous exercise.
Speaking of ligaments, many people may have just heard of it, but they don't know what it is for. Generally speaking, when a ligament is broken, people will be annoyed. Ligament rupture is like the feeling that the hero's hamstring is broken in the costume drama, which is very important in the human body.
Compared with ligaments, people may know less about meniscus. Meniscus is a piece of cartilage on the knee joint. Because of its elasticity, it can cushion the impact of two bone surfaces, absorb vibration, spread synovial fluid, increase lubrication, reduce friction and protect joints, so it is very important in daily walking, and the meniscus will wear, so the inconvenience of many elderly people's legs and feet may be caused by the perennial wear of the meniscus.
I have ligaments, meniscus and patella on my knee, because I once hurt my knee directly because of heavy physical labor. At that time, the ligament was broken and cracked in half, and the meniscus was injured, accompanied by patellar dislocation. My leg is all right after the operation, but the lesson I learned from this incident is that everything should be done according to one's ability, not too hard.
Speaking of meniscus, I have to mention that it secretes lubricating fluid, which can make daily walking more convenient. The meniscus injury is also classified into three grades: first degree injury, second degree injury and third degree injury. If the third degree injury is reached, the damaged meniscus is likely to be removed. If the meniscus is replaced, it will not be permanent. After all, the artificial meniscus does not secrete lubricating fluid, and it is likely to be replaced in several years to more than ten years depending on the material.
Speaking of kneecaps, I can't help thinking of a historical figure, that is, Sun Bin, an outstanding strategist in the Spring and Autumn Period and the Warring States Period. Actually, his name is not verified. I only know that his ancestor was Sun Wu, the author of The Art of War. Later generations called him Sun Bin because he was whipped, that is, his patella was dug out.
Personally, when exercising and keeping fit, the most important things are two points:
Pay attention to the intensity of fitness and be temperate.
Try to diversify the fitness programs.
Speaking of fitness intensity, I think of a female colleague in the office. She doesn't exercise often, and suddenly wants to lose weight, so she went to get a fitness card. When she first learned spinning from the coach, she was overworked. After riding, she didn't feel anything, but for the next week, her legs were sore and painful, and it was difficult to walk. Therefore, we must exercise moderately. If we are strong, the intensity of exercise can be higher. If we are weak or obese, we should gradually reduce the intensity of exercise.
Recently, the most popular exercise for middle-aged and elderly people is hiking. My father likes hiking very much. Every evening, he would walk in line with a group of players for an hour. He has been hiking for many years, and their pace can't keep up with the average person. Therefore, junior hikers should go by themselves first, and don't blindly follow the team.
According to the advice of professional doctors, the number of steps that ordinary people walk every day is about10.5 million, and those who are physically strong can have more, while those who are obese or weak should keep it at about 5,000 steps.
In addition to maintaining a certain intensity of exercise, it is also important to diversify sports, so that one of our joints will not be constantly rubbed and damaged. For example, you can choose ball games, hiking, pull-ups and other sports to exercise all kinds of bones.
Because my leg has been injured, I dare not exercise my leg at high intensity. I will choose my own suitable exercise, such as lifting dumbbells, sit-ups and cycling.
My father is old, but he loves sports. The best thing is that he has many hobbies, such as hiking. At the same time, he also likes playing table tennis and riding a bike. Diversified sports make his physique very good among his peers.
Therefore, in order to lose weight, it is very undesirable to overdraw your body. It doesn't matter if you are not good-looking. As long as you are healthy, you can't stop moving and don't move. Be sure to grasp the scale of your body!
