Cadence in sports involving running is the total number of 'revolutions per minute' (RPM), or number of full cycles taken within a minute, by the pair of feet, and is used as a measure of athletic performance. It is very similar in respect to cadence in cycling, however it is often overlooked in its importance in the sports of running and racewalking. This discrepancy may be attributable to other factors of importance in running, including stride length, technique, and other elements pertaining to bio-mechanical efficiency.
