There are numerous potential health benefits for women who exercise during pregnancy, including better weight control, improved mood and maintenance of fitness levels. Regular exercise during pregnancy can also decrease the risk of pregnancy-related complications such as pregnancy-induced hypertension and pre-eclampsia.Before exercising when pregnant, consult your doctor, physiotherapist or healthcare professional. You may need to modify your existing exercise program or choose a suitable new one if you were exercising very little before getting pregnant.
Benefits of exercise during pregnancy
Exercising and changes associated with pregnancy
Your body will undergo many changes during pregnancy. Some will affect your ability to exercise, or require you to modify your exercise routine, including:
• Hormones such as relaxin loosen ligaments, which could increase your risk of joint injuries
• As pregnancy progresses, your weight will increase and you will experience changes in weight distribution and body shape. This results in the body’s centre of gravity moving forward, which can alter your balance and coordination.
• Pregnancy increases your resting heart rate, so don’t use your target heart rate to work out the intensity of your exercise.
• Your blood pressure drops in the second trimester, so it is important to avoid rapid changes of position – from lying to standing and vice versa – so as not to experience dizzy spells.
