But theory belongs to theory. From my personal experience, most female physiological periods are not suitable for training, mainly for the following three reasons:
First, it is quite common that strength training or more vigorous exercise during the physiological period will lead to an increase in blood volume. Even in the last few days of menstruation, although the blood volume is already very small, such problems will occur if you do not pay attention to reasonable training.
Second, one week before menstruation, the hormone concentration in our body all dropped. Our athletic ability is the worst at this time. You will find that the burden you usually add to yourself has been greatly reduced during this time. Many people have to finish the training even if they have to force themselves to do it during the physiological period. In fact, there is no need to cram at the last minute, which will only make you more tired.
Thirdly, in the luteal phase, when estrogen and lutein decrease at the same time (that is, one week before menstruation and during menstruation), our mood will be affected by them. Many women will feel anxious, depressed, fidgety, tired, dysmenorrhea, backache and so on. This state is very unsuitable for training. If you enter the training ground with a negative attitude, it is difficult for you to concentrate, and many women are injured.
Therefore, if you insist on exercising during menstruation, you must make appropriate adjustments:
1. Gradually reduce the amount of training one week before the physiological period, and rest for three days before the physiological period without training.
2. If there is less bleeding after three days of physiological period, you can start to do some soothing upper limb training movements. Don't do some strength training that will increase intra-abdominal pressure, such as squat movements and core training movements.
3. Normal training will not be resumed until the end of the physiological period.
I hope it helps you!
