Running calf pain may be caused by muscle strain, lactic acid buildup, and insufficient blood supply.
1. Muscle strain: For people who lack exercise for a long time, when they run fast, such as sprinting, due to the explosive contraction of calf muscle groups, it is easy to have spasm and strain of calf muscles such as gastrocnemius muscle and flounder muscle, especially when there is no timely and proper relaxation exercise after exercise, muscle pain will occur.
2. Lactic acid accumulation: when running fast for a long time, due to the huge consumption of oxygen and energy by the tissue cells, the calf muscles are relatively lacking in oxygen, and the large number of anaerobic respiratory function of the skeletal muscle cells leads to the accumulation of a large amount of lactic acid, so there will be muscle soreness.
3. Insufficient blood supply: for patients suffering from lower extremity atherosclerosis, thromboembolic vasculitis and other diseases, when running due to muscle contraction, oxygen demand increases, while the blood vessels are relatively narrow, the blood supply is insufficient, and calf muscle pain occurs.
Running running calf pain may also be related to other factors, it is recommended to consult a doctor in time for a clear diagnosis.
