We often say that women can also exercise appropriately during pregnancy. So, what are the effects of strenuous exercise on us?
Experts note:
Recommended BMI
The intensity and duration of exercise can affect female fertility, but there is no significant difference in the specific form of exercise.
Scientific basis for the recommendations for pregnancy preparation exercise:
An epidemiological study defining strenuous activity as activity that consumes at least 6 kcal/min concluded that strenuous exercise is associated with anovulatory infertility.
A Danish study suggested that strenuous physical activity (e.g., running, brisk cycling, aerobics, swimming, gymnastics) leads to longer periods of conception.
Another study showed that in women who performed IVF, if they exercised vigorously for 4 hours per week, the IVF cycle live birth rate was reduced by 40%, and the cycle cancellation rate increased by 2 times.
Decreased fertility due to strenuous exercise may be related to the following factors:
Decreased synthesis of progesterone in the luteal phase (i.e., insufficient luteal function).
By altering the production of GnRH (gonadotropin-releasing hormone), it affects the secretion of LH (luteinizing hormone) and FSH (follicle-stimulating hormone), causing ovulation disorders.
Alters leptin levels in the body and affects our body's energy balance and weight.
During the preparation for pregnancy, you can follow the above recommendations, avoid strenuous exercise, and carry out appropriate physical exercise to effectively promote normal conception!
