Many pregnant women wonder about the heart rates to respect during physical training. Here is some information that you may find useful.

If you are used to measuring your effort using your heart rate, you will probably notice some changes during your pregnancy. Heart rate can be influenced by many factors, including hydration, level of fatigue, outside temperature, time of day, ingestion of stimulants such as caffeine and, during pregnancy, increased blood volume.
Target heart rate during pregnancy
The table below gives the percentage of the desired intensity of physical activity in relation to the maximum heart rate. The maximum heart rate (HRF) is the number of beats per minute that you can reach during a very high intensity exercise, for example during an intense effort of one to two minutes. An FCM test is very demanding and should never be done during pregnancy. You can estimate it using the following formula: FCM=208-(0.7xage).
This table shows data for women who have nomajor he alth problem. The efficiency of the cardiorespiratory system varies from person to person, and therefore the actual heart rate may vary for the same intensity.
