Physiological and Biomechanical Benefits | Zephyr™ Performance Systems

Heart Rate: Beats per minute
Breathing Rate: Breaths per minute
Heart Rate Variability: Measure of the variation in the time interval between individual beat detections

Posture: Physical positioning of the torso in relation to the X and Y axis
Activity: Vector magnitude units in how the various axis points are added (lateral, sagittal and vertical); ~0.2 VMU for walking and ~0.8 for running
Peak Acceleration: Greatest recorded instantaneous movement on an object or body
Accelerometry: Three axis calculation of the body's movement
Impact: Force exerted upon the body; based on G's

Jump Height & Flight Time: Distance in feet of a jump with the allotted time in the air
Explosiveness: The ability to exert strength or force as rapidly as possible in a given action
Peak force: Greatest recorded instantaneous force on an object or body

Heart Rate Confidence: Expressed as a percentage for level of confidence the BioModule is picking up heart rate during activity (dependent upon wear detection and ECG)

Estimated Core Body Temperature: Minute by minute algorithm using heart rate to calculate estimated temperature
Caloric Burn: Heart rate calculation for calories expended
Percent of Heart Rate Max: Percentage of an individual's predetermined maximum heart rate, usually derived from a standardized test such as a fitness test
Percent of Heart Rate at Anaerobic Threshold: Percentage of heart rate at an individual's anaerobic threshold usually derived from a standardized test such as a fitness test
Heart Rate Recovery: Drop in the heart rate following cessation of activity over a 30-second interval (or 60-second, 120-second or 180-second intervals)

Physiological Load: Cumulative index of effort based on heart rate over a period of time
Physiological Intensity: Instantaneous index of effort based on heart rate at that moment
Mechanical Load: Cumulative index of effort based on acceleration over a period of time
Mechanical Intensity: Instantaneous index of effort based on acceleration at a particular moment
Training Load: Average of the mechanical and physiological load in one number
Training Intensity: Average of the mechanical and physiological intensity in one number

GPS Speed: Based in miles per hour
GPS Distance: Based in total miles accumulated
GPS Elevation: Based on total elevation changes in feet above sea level
Blood Pressure: Measured through peripheral sensors running (in Bluetooth mode only)
SpO₂: An estimate of the amount of oxygen in the blood. More specifically, it is the percentage of oxygenated haemoglobin (haemoglobin containing oxygen) compared to the total amount of haemoglobin in the blood (oxygenated and non-oxygenated haemoglobin)
