I feel pain on one side of my abdomen.
When running, many people will feel pain in one side of their abdomen. In this case, we must first determine whether they have gastrointestinal diseases and whether they have eaten within 30 minutes before exercise. Excluding these factors, this situation may be caused by diaphragm spasm (separation of chest and abdominal cavity). Just breathe. When exhaling and inhaling, press the diaphragm with your hand slowly.
Skeletal joint ring
When many people are running, their arms, legs and other parts will always make a "cough" sound. This is because tendons and ligaments will shift when joints move, and they will make a sound when they return to their original positions. Arthritis patients will also make such a sound when running, because arthritis will destroy the cartilage tissue between joints, resulting in the joint contact surface is no longer smooth, and it will make a noise when rubbing. If the moving joints are painful, stop exercising immediately.
leg cramps
This is a severe muscle spasm. This will happen if the muscles continue to contract too fast, the relaxation time is too short, the local metabolite lactic acid increases, and the contraction and relaxation of muscles are difficult to coordinate. At this time, you can stop and stretch your limbs, or immediately grab the toes on one side of the cramped leg with your hands, then slowly straighten your feet, and then stretch your legs hard to relieve the pain.
Muscle aches
The main manifestation of muscle soreness is a burning sensation in muscles, which many people call "hypoxia". At this time, the most effective way is to slow down or end the exercise.
Stiff legs
I think there is lead in my leg. When you run within the limit for too long, it will cause muscle fiber damage. At this point, we must slow down to avoid permanent damage.
