Squat: If it is difficult to squat, or if the knee hurts when squatting, it is difficult or impossible to get up, degenerative diseases such as narrowing the joint space may have occurred.
Walking: If the posture when walking begins to become unnatural and the legs can't be straightened, it means that the gap of the knee joint is narrowed, and the knee joint is severely deformed and varus occurs.
Lie flat: If you press the kneecap with your hand and "grind" it down, if you feel pain at this time, it means that you have the symptoms of patella softening.
Under what circumstances is the knee most vulnerable to injury?
When we lie down, the knee joint is not stressed.
When standing and walking, the load is once or twice.
When going up and down slopes and stairs, the weight of the knee joint is four times.
When running, it is more than four times.
Six times as much as when playing ball,
When kneeling, it is eight times.
Therefore, it is necessary to reasonably control some exercises in which the knee joint bears heavy weight.
Diet plus exercise can enhance the effect.
A) eat anti-inflammatory food
When a joint is inflamed, it becomes weak and painful. Eating anti-inflammatory food helps to keep your knees strong. As we all know, flaxseed, olive oil, avocado and whole fruits and vegetables have anti-inflammatory effects.
B) take enough vitamin e.
Vitamin E is thought to inhibit the enzymes that break down articular cartilage. Spinach, cauliflower, peanut, mango and kiwifruit are all rich in vitamin E.
C) eat more calcium.
Bone health is very important for knee strength, so you must take measures to prevent osteoporosis. Milk, yogurt, cheese and goat milk are all good sources of calcium. Almonds and green leaves are also rich in calcium.
