About Training Effect

Training Effect measures the impact of an activity on your aerobic and anaerobic fitness. Training Effect accumulates during the activity. As the activity progresses, the Training Effect value increases. Training Effect is determined by your user profile information and training history, and heart rate, duration, and intensity of your activity.

Aerobic Training Effect uses your heart rate to measure how the accumulated intensity of an exercise affects your aerobic fitness and indicates if the workout had a maintaining or improving effect on your fitness level. Your excess post-exercise oxygen consumption (EPOC) accumulated during exercise is mapped to a range of values that account for your fitness level and training habits. Steady workouts at moderate effort or workouts involving longer intervals ( > 180 sec) have a positive impact on your aerobic metabolism and result in an improved aerobic Training Effect.

Anaerobic Training Effect uses heart rate and speed (or power) to determine how a workout affects your ability to perform at very high intensity. You receive a value based on the anaerobic contribution to EPOC and the type of activity. Repeated high- intensity intervals of 10 to 120 seconds have a highly beneficial impact on your anaerobic capability and result in an improved anaerobic Training Effect.

Anaerobic base: Your ability to maintain easily repeated efforts of 10 to 120 seconds at a medium effort. This builds the foundation for harder anaerobic training because your muscles are repeatedly working with moderate lactate levels. Your focus during this activity is to maintain good technique.

Anaerobic capacity: The average power you can sustain in a 30 to 120 second maximum effort. Your goal during this activity is to improve your ability to produce and metabolize lactic acid.

Anaerobic power: The peak power you can reach in a 5 to 15 second maximum effort. This type of workout tests the condition of the neuromuscular and intramuscular systems.

Aerobic recovery: Your activity effort is easy and allows you to slightly boost your cardiorespiratory fitness level.

Aerobic base: Your activity effort is average and allows you to maintain your current cardiorespiratory fitness level.

Aerobic tempo: Your activity pace is comfortably difficult and allows you to improve your cardiorespiratory fitness level.

Aerobic threshold: Your activity effort is intense and allows you to improve your lactate threshold.

Aerobic VO2 max.: Your activity effort is demanding and you are spending time above your current lactate threshold. This allows you to improve your VO2 max. estimate.

You can add Aerobic Training Effect and Anaerobic Training Effect as data fields to one of your training screens to monitor your numbers throughout the activity.
