[[File:HeartRateSimplified.svg|right|thumb|500px|A simplified chart of heart rate against exercise intensity showing [[Maximum Heart Rate]], [[Heart Rate Reserve]], [[Resting Heart Rate]], [[Orthostatic Heart Rate]], [[Zero Power Heart Rate]], and [[Heart Rate Deflection]].]]
Zero Power Heart Rate (HR<sub>zero</sub>) is how fast your heart beats when you are not generating any useful power by moving, such as standing still. HR<sub>zero</sub> is typically different to [[Resting Heart Rate]] (HR<sub>rest</sub>) which is measured sitting or lying down. While this difference can be small, it does change the calculation for [[Heart Rate Reserve]] and for calculating [[Running Economy]] and [[HrPwr]]. The difference between HR<sub>zero</sub> is typically different to [[Resting Heart Rate]] (HR<sub>rest</sub>) is used in the orthostatic test, where a difference of >30 BPM is a diagnosis for hypovolemia (low blood volume) <ref name="AHRQ"/><ref name="PalatiniBenetos2006"/>.
