Exercise has become a very important part of women's daily life, even during pregnancy, most women like to exercise, to maintain blood circulation, but there are some problems of safety with some exercises, due to some physiological changes that occur during pregnancy. To ensure a good healthy pregnancy, these considerations should help. Since there is an increase in pregnant women's endocrine system and blood sugar levels, there are some guidelines to help pregnant women. There are many changes that occur starting from musculoskeletal, maternal and fetal temperature, hemodynamics, oxygen, high blood pressure, diabetes, energy needs, impact of pregnancy on performance during physical activity, labor and pregnancy outcome, the normal adaptations that occur during pregnancy in women so that they can provide accommodation in the embryo or fetus. These physiological changes are absolutely normal, and also include cardiovascular, metabolic, renal and respiratory changes which become very important in case of complications. The body must adapt its physiological and homeostatic mechanisms during pregnancy to adequately provide for and ensure safety for the fetus. A woman is the sole provider of nutrition for the embryo and fetus, so her plasma and blood volume slowly increases during the course of pregnancy. pregnancy to adapt to changes. The increase in plasma volume is due to the increase in aldosterone. It also results in an increase in stroke volume and cardiac output by approximately 50%, especially during the first trimester. Cardiac function is modified by an increase in heart rate and stroke volume. After pregnancy, the change in stroke volume will not be returned to normal. Cardiac output increases from 4 to 7 liters in t...... middle of paper...... avoids considerable discomfort. Patients should conduct frequent self-assessments of physical well-being, as well as hydration, calorie intake, quality of rest, and muscle or joint pain. It should be explained to the patient that decreased physical performance will be common, most likely in the later stages of pregnancy. The main goal is to enable the pregnant patient to obtain the best results and benefits from exercise for general well-being. While ensuring that there are no adverse effects on the mother or developing fetus.
