We measured heart rate during an EVA: The EVA was on a mixture of flat ground, with stops for science measurements, and some work going up and down hills. The interesting result is that the heart rate was at the highest when getting ready and going through the airlock. It takes quite a lot to get ready, and can be a bit nerve racking!
During the EVA the heart rate didn't get any higher, as we paced ourselves carefully whilst wearing the heavy EVA equipment..
Highest Rate: 118 bpm (beats per minute)
Lowest Rate: 66 bpm.
