The patella strap is tied to the knee. There are many blood vessels in the legs, which play the role of transporting blood and oxygen. If the patella strap is too tight, it is easy to compress the skin and subcutaneous blood vessels, resulting in poor blood flow. Insufficient blood supply to the legs for a long time will also cause cold legs and feet, weakened consciousness, insensitivity to cold and heat, and affect normal movement.
Therefore, when wearing the patella strap, be careful not to tie the patella strap too tightly. If you feel uncomfortable during exercise, you can also check whether the patella strap is too tight.
