Pregnant women maintain body temperatures within safe limits during moderate-intensity aqua-aerobic classes conducted in pools heated up to 33 degrees Celsius: An observational study

Abstract

Question: What is the body temperature response of healthy pregnant women exercising at moderate intensity in an aqua-aerobics class where the water temperature is in the range of 28 to 33 degrees Celsius, as typically found in community swimming pools? Design: An observational study. Participants: One hundred and nine women in the second and third trimester of pregnancy who were enrolled in a standardised aqua-aerobics class. Outcome measures: Tympanic temperature was measured at rest pre-immersion (T1), after 35. minutes of moderate-intensity aqua-aerobic exercise (T2), after a further 10. minutes of light exercise while still in the water (T3) and finally on departure from the facility (T..
