Heart Rate

Heart rate is the number of times the heart beats per minute. In space and astronautical engineering context, heart rate is an important physiological parameter that is monitored during spaceflight to assess the cardiovascular health of astronauts. The microgravity environment of spaceflight can cause changes in the cardiovascular system, including a decrease in heart rate and blood volume, which can lead to orthostatic intolerance upon return to Earth. Monitoring heart rate during spaceflight can help identify these changes and inform countermeasures to mitigate their effects. Additionally, heart rate can be used as a measure of physical exertion during extravehicular activities (EVAs) and exercise sessions, which are important for maintaining astronaut health and fitness in space.
