A

Active Recovery Zone Zone used for recovery from hard workout out from day before or used as a cool down at the end of a workout. 50-55% of FTP

Acute Training Load (ATL) The overall quantity (i.e., combination of frequency, duration and intensity) of training that you have performed recently (during the past week or two).

Anaerobic Capacity The overall quantity of work that an athlete can perform by relying solely on anaerobic metabolism.

Anaerobic Threshold (AT) / Lactate Threshold (LT) The exercise intensity at which the release of lactate into the blood first begins to exceed its rate of removal so that it begins to accumulate into the person’s blood.

B

Beats Per Minute (BPM) Unit of measurement of an individual’s heart rate in number of heart beats per one minute.

C

Cadence The revolutions per minute (rpm) of the cranks at which you pedal.

Calorie A quantity of food capable of producing such an amount of energy.

Chronic Training Load (CTL) The overall quantity (i.e., combination of frequency, duration and intensity) of training that you have been performing over a substantial period of time – for example, several months or more.

D

Distance The extent or amount of space covered throughout a given workout – Often measured by miles or kilometers with regard to cycling

Duration The length of time covered throughout given workout, interval, etc.

E

Elevation The altitude of a place above sea level.

Elevation Gain The total vertical distance in feet or meters traveled or climbed over a given distance ridden.

Endurance Zone Zone used to build endurance base and enhance aerobic fitness/stamina. 65-75% of FTP

F

Functional Threshold Power (FTP) The highest power output, in watts, that an athlete can sustain at a steady state for approximately one hour.

Functional Threshold Heart Rate (FTHR) In accordance with FTP, FTHR is The highest heart rate output, in BPM, that an athlete can sustain at a steady state for approximately one hour.

I

Intensity Factor (IF) The ratio of the normalized power to the rider’s functional threshold power (FTP)

J

Joule The unit of work or energy, equal to the work done by a force of one newton when its point of application moves through a distance of one meter – Unit of power measured by watts multiplied by time in seconds

K

Kilojoule Measurement of energy equal to 1000 joules

L

Lactate Threshold (LT) / Anaerobic Threshold (AT) The exercise intensity at which the release of lactate into the blood first begins to exceed its rate of removal so that it begins to accumulate into the person’s blood.

M

Maximal Heart Rate The maximum rate at which your heart can beat per minute

N

Neuromuscular Power Bursts Short, high intensity efforts usually lasting less than 10 seconds

Normalized Power An estimate of the power the rider could have maintained for the same physiological "cost" if the output power was constant.

O

Overtrained A chronic state of fatigue and diminished performance due to excessive training.

P

Percent Grade A measure of the steepness of a climb

Power Intervals Used to elicit improvements in strength as well as Vo2 max, this zone is performed at power intervals over FTP. 120-130% of FTP

R

Rate of Perceived Exertion (RPE) An individual's rating of effort or intensity typically scored on a 1 to 10 scale where 1 is equal to rest and 10 is equal to a maximal or all out effort.

S

Steady State Zone Zone aimed at raising an athlete’s FTP. This is performed at just under FTP wattage. 98% of FTP

T

Tempo Zone Sub-threshold zone where cyclists ride in more than any other. This zone is more intense than endurance pace, but less than threshold and greatly benefits muscular endurance. 76-90% of FTP

Training Stress Score (TSS) A composite number that takes into account the duration and intensity of the workout to arrive at a single estimate of the overall training load and physiological stress created by that session.

Training Stress Balance (TSB) The balance between fitness and freshness with fitness based on training stress or training load, which can be renamed “form”.

Training Zones Defined This is the 7-zone system Kinetic uses with the Kinetic Fit power-training app.

  • Zone 1: Active Recovery – used for recovery days after a hard workout days or used as a cool down at the end of a workout = < 55% of FTP
  • Zone 2: Endurance – used to build an endurance base and enhance aerobic fitness/stamina = 56% - 75% of FTP
  • Zone 3: Tempo – the sub-threshold zone cyclists will ride in more than any other. This zone is more intense than endurance pace, but less than threshold pace and greatly benefits muscular endurance = 76 - 90% of FTP
  • Zone 4: Lactate Threshold – training in the Steady State zone targets raising an athlete’s FTP. Workouts are performed just over and/or just under FTP wattage = 91% - 105% of FTP
  • Zone 5: VO2 Max – used to elicit improvements in strength and VO2 max = 106% - 120% of FTP
  • Zone 6: Anaerobic Capacity = 121% - 150% of FTP
  • Zone 7: Neuromuscular Power = maximum effort

V

Variability Index (VI) The ration of Normalized Power to average power, Variability Index provides an indicator of how variable, or “stochastic,” a rider’s power output was during a particular workout.

Velocity The distance traveled in a given time frame normally expressed in meters per second, kilometers per hour, or miles per hour. (i.e. speed)

VO2 Max The maximal amount of oxygen uptake that an individual can achieve during exercise – considered best measure of a person’s cardiovascular fitness and sets upper limit to aerobic power production.

W

Watts Unit used to measure/express power output at a given time while cycling – Unit of power equal to joule output per second.

W/Kg (Watts per kilogram) A cyclists power-to-weight ratio determined by wattage output per kilogram of body weight.
