Regular exercise is important for general health and wellbeing during pregnancy. The physical changes experienced during pregnancy need to be taken into consideration when planning an exercise routine.
With the increased weight gain and change in body shape, a pregnant woman’s sense of balance and coordination are affected.
The hormone Relaxin makes joints and ligaments looser, potentially increasing the risk of injury. In addition, the heart rate, breathing rate and the core body temperature is increased in pregnancy.
Pregnancy hormones can contribute to a feeling of breathlessness.
Here are some tips to make you more comfortable:
• Drink plenty of water when exercising
• Wear cool, comfortable, loose fitting clothes and a good supporting bra.
• Exercise in a well ventilated area.
• Do a warm up stretching routine
• Be aware of your physical limitations
• Avoid hot tubs, saunas and spas
• Don’t exercise if you feel unwell or have a temperature
• Avoid exercise after 20 weeks lying flat on your back
• Avoid prolonged periods of standing
• Avoid sudden jerky movements such as bouncing, jumping or sudden changes in direction
• Do pelvic floor exercises
Joining an exercise class is a great way to stay fit and meet new friends during your pregnancy.
Recommended exercises in pregnancy:
• Pilates, Yoga
• Aerobics
• Aqua
• Walking, swimming, jogging
• Physiotherapy exercise classes and pelvic floor exercises
If you experience any of the following symptoms: pain, bleeding, chest pain, shortness of breath, uterine contractions, abdominal pain, decreased fetal movements or bleeding before, during or after exercise contact your Obstetrician.
If you have a complicated pregnancy (ie twins, placenta praevia, persistent bleeding) you may be advised not to exercise or to modify your exercise.
