Some girls may feel backache, abdominal pain, excitability and other discomforts during menstruation, so they think that girls can't take part in sports during menstruation, and even don't take part in physical education class and recess exercise at school, thus imprisoning themselves. In fact, this approach is not entirely correct. Menstruation is a normal physiological phenomenon of human body, and it is generally not necessary to stop physical exercise during menstruation. On the contrary, taking part in some physical activities during menstrual period can improve the blood circulation of pelvic cavity, regulate the process of brain excitement and inhibition, make people feel happy and reduce troubles. But menstrual exercise should pay attention to the following points: (1) Reduce the amount of exercise. You might as well take part in some sports that you usually take part in and are used to, such as jogging, gymnastics, boxing, table tennis, shooting, practicing eighteen methods and so on. Pay attention to shortening the exercise time and slowing down to reduce the amount of exercise and relax the muscles. (2) Avoid taking part in violent vibration. During menstruation, it is not advisable to participate in high jump, long jump, pitching, 100-meter race, playing football, etc., nor do strength exercises such as push-ups and dumbbells to increase abdominal pressure, so as to avoid excessive menstrual bleeding or change the position of the uterus. (3) Be able to participate in various water sports.

Of course, if the menstrual reaction is really too heavy, you can temporarily stop taking part in sports and go to the hospital for examination and treatment in time.
