Cadence
Cadence is walking rate in steps per minute, and is related to walking speed (speed = cadence x stride length) and intensity of activity. Cadence is one measure that can be used to check that adequate activity levels in daily living are being reached, since averaged cadences throughout a day will differ from the cadence of a pure walk.

Walking cadence for exercise intensity - According to federal guidelines, adults should be reaching 150 mins of moderate or 75 mins of vigorous exercise per week. Walking at certain cadences can be a means to achieve that: low mean daily cadence = 60-79 steps/min, medium daily cadence = 80-89 steps/min, brisk daily cadence = 100-119 steps/min, faster locomotion = 120+ steps/min.
