Write the reminder on the front:
Although exercise brings pressure to the knee joint, reasonable exercise is beneficial to the health of the knee joint:
Strengthen the muscles around the knee joint, especially the quadriceps muscles, buffer the pressure brought by daily activities to the knee joint, and reduce joint wear;
Stimulates the flow of synovial fluid in the joint cavity, nourishing and lubricating the joint cartilage
A 2017 study found that hip or knee arthritis occurred in 3.5% of daily fitness runners, while 10.2% of people who did not run for a long time every day had hip or knee arthritis. [1]
As the old saying goes, "Flowing water does not rot, the household center does not beetle", so if you want to use the knee joint healthily for a long time, everyone still has to move more, of course, it is reasonable exercise.
At the beginning of the exercise or the knee joint will appear unwell after strenuous exercise, it is recommended to choose the chart of the knee joint impact is relatively small, such as rowing machine, elliptical machine, stationary riding and so on.
Of course, if there is already persistent discomfort or pain in the knee joint, go to the orthopedic department as soon as possible, and don't exercise first.
What kind of exercise do you usually like to do?
