Regular exercise can properly stimulate articular cartilage, promote metabolism, make synovial fluid flow everywhere in the joint, and play a role in lubrication and nutrition. On the contrary, if you don't exercise for a long time, the muscle tissue around the joints will shrink day by day. Over time, the joint loses protection and the probability of injury will naturally increase.
Precautions for running
Some obese people who run to lose weight must avoid misunderstandings, otherwise they will really hurt their knees. For example, obese people wear hard-soled shoes to run on asphalt roads, and the load on the knee joint is very large. You should choose soft-soled shoes and run on the grass or plastic track. For obese people, it is best to choose swimming, cycling and other sports that have less damage to the knee joint.
In addition, running takes a certain amount of time, and short-term exercise is difficult to achieve results. The lower limit of each run is 20~30 minutes, and the upper limit is 1~ 1.5 hours. This amount of time does not need to be completed at one time, and can be accumulated in one day.
