Be aware that resting heart rate may increase by ten to 15 beats per minute, and heart rate is more variable in response to exercise. Therefore, exercisers should check their pulse every four to five minutes during peak activities making sure they are maintaining appropriate training heart rate. Maternal core temperature should not exceed 38 degrees Celsius, because pregnant women are less efficient at exchanging heat. Pay attention to heat factors and avoid vigorous exercise in hot, humid weather. Hydration before, during, and after exercise affects core body temperature.
Dehydration increases core temperature to dangerous levels and can precipitate premature labor.
Drink plenty of water despite concern about urinary frequency. If you're going to exercise during pregnancy, be sure to take care. Shop O2 . All Rights Reserved.
