What are the effects of playing badminton on the knees?

There are many things in life that have two sides. When we analyze anything, we should look at it dialectically and not be too extreme in looking at anything. Playing badminton has a positive side on the knees, and of course a negative side. Of course, the positive side is more than the negative side. Next, let us understand what effects playing badminton has on the knees?

How to take care of your knees at every age? Especially middle-aged and elderly people should pay more attention to protecting their knees!

The more weight the body bears, the greater the chance of joint cartilage wear, the more susceptible the tendons are to injury, and the faster the knee joint degenerates.

The knee load multiples are as follows:

1. When lying down, the weight on the knees is almost zero.

2. When standing up and walking, the load on the knees is about 1 to 2 times.

3. When going up and down slopes or stairs, the load on the knees is about 3 to 4 times.

4. When running, the load on the knees is about 4 times.

5. When playing ball, the load on the knees is about 6 times.

6. When squatting and kneeling, the load on the knees is about 8 times.

For example: For a person weighing 50kg, the knees have to bear a weight of about 200kg every time they climb a step. (50*4 times) The human knee joint is in the best condition for 15 years. Before the age of 15: the knee joint is in the development stage, and the growing pains during adolescence often occur near the knee joint.

15 to 30 years old:

The knee joint is in "perfect condition" and works tirelessly. As long as the knee joint tissue is not damaged, you can basically not feel its presence.

30~40 years old:

The patellar cartilage undergoes mild early wear and tear, and then goes through a fragile period with short-term knee pain that lasts for a few weeks to a few months, which some people may not even notice. The patellar cartilage is a 3 to 5 mm thick layer of transparent cartilage inside the human knee joint, which can cushion the impact of movement on the knee joint. However, since the patellar cartilage has no nerve distribution, the "warning signal" will only be sounded once during the fragile period before the entire layer is worn out. During this period, strenuous exercise should be avoided. It is also from this time that the knee joint can no longer be used as you please.

Ages 50 and above:

The knee joint will feel obvious pain because the "service life" of the patellar cartilage has reached the end, the entire layer of cartilage has been worn out, and arthritis has occurred. At this time, you should use your joints sparingly and reduce strenuous exercise, especially going up and down stairs and climbing mountains. If necessary, you can use crutches to reduce the pressure on the knee joints. The causes of knee pain in middle-aged and elderly people: After middle age, the tendons and ligaments of the knee joint begin to undergo degenerative changes, the synovial fluid secretion in the joint cavity decreases, long-term friction on the joint bone surface causes bone wear, and the tissues around the joint are prone to fibrous adhesion due to inflammation and other reasons, so the elderly often feel stiff knee joints. It will make a "clicking" sound or friction sound when moving, and will induce pain, swelling, and joint effusion when exposed to cold or excessive activity. In severe cases, it will cause joint deformities and disability in the elderly.

The positive impact of playing badminton on the knees is that it can promote bone development and is beneficial to the height growth of adolescent boys and girls. Its negative side is that if people do not pay attention to safety while playing badminton, it can easily lead to injuries. However, we cannot stop playing badminton because of these negative effects. We just need to pay more attention.
