If the leg strength is weakened, the probability of people falling will greatly increase. For middle-aged and elderly people, falling down may be the most unbearable thing. Because you are likely to accidentally fall, your physical fitness will become worse than before, and it will also accelerate the overall aging of your body.
Therefore, if you want to live a long and healthy life, you must not ignore the exercise of lower limb strength. When exercising at ordinary times, you can do some targeted actions to improve the strength of lower limbs.
In addition, some common knee injuries should be avoided as much as possible.
Old legs fail first! Reminder: Don't do these four common knee injuries in the future.
Cross your legs
You must be familiar with crossing your legs. I guess a lot of people do this every day. Crossing your legs is naturally much more comfortable than sitting, and many people may switch from sitting to crossing their legs in life.
In the process of crossing your legs, your body's center of gravity will shift to one side. Over time, there will be uneven stress on both sides of pelvis, which will increase the probability of suffering from lumbar intervertebral disc, affect the blood circulation speed of lower limbs, and also damage the knee joint. Knee cartilage is non-renewable, and too much friction will inevitably lead to premature "retirement" and knee pain, thus weakening the strength of lower limbs.
sedentary
If crossing your legs is something that most people do every day, then sitting still may be everyone's daily action.
Many people need to rely on computers to work every day, so of course they need the cooperation of sitting posture. Even if you keep sitting, sedentary is harmful to your health, not to mention sitting incorrectly.
When you sit, your legs are still. If you don't exercise for a long time, it doesn't seem to consume your knee joint, but it will actually increase the probability of knee arthritis.
This is mainly because, in the process of exercise, people's muscles and articular cartilage have been exercised to a certain extent and have been in an active state, and proper exercise can enhance their stability. While sitting still, the blood circulation of lower limbs slows down. If you are still used to crossing your legs, it will also compress the nerves in your legs, accelerate muscle loss and reduce joint stability.
Carry heavy objects
People who engage in physical activities may often carry some heavy objects. Many people are used to bending over to carry heavy objects, which is not conducive to protecting the waist, but also increases the burden on the knee joint, leading to serious damage to articular cartilage and increasing the risk of arthritis and lumbar diseases.
The correct posture to move heavy objects should be to bend your knees first, and then lift them with your hands. If you already have problems such as lumbar muscle strain and knee joint aging, don't move heavy objects.
Climb up the steps
Climbing stairs can exercise to lose weight, and it is also a kind of behavior that hurts your knees.
When climbing stairs, both legs need to step on the steps. In this process, the total weight of the human body is mainly placed on one leg, so when you bend your knee repeatedly, the number of rubbing of articular cartilage will increase one after another. If it goes on for a long time, the damage to the knee joint will be great and it will be difficult to repair.
The above four behaviors are common knee injuries in life. After reading this tweet, if you don't want your knees to age quickly and your body to enter an aging state in advance, I advise you to do less.
That's what I want to share with you today. I hope it helps you.
