30 - Tracking your activity and physical condition
anaerobic energy systems. In a low-intensity workout, aerobic
systems provide energy. In contrast, in a high-intensity workout,
energy is supplemented by the faster anaerobic system.
Understanding how your body uses these two systems allows you to
perform better in endurance exercises.
Estimating Stamina
The ’Stamina’ rating is based on information in your
profile, such as gender, age, height and weight, with
additional reference to daily step and heart rate
measurements. While you are exercising, the green
border around the Leap Ware screen indicates your
current Stamina - a full green arc means your Stamina is at 100% and
as your Stamina is used, the arc will gradually disappear.
Stress and fatigue
What is Stress?
Stress is a reaction to physical, mental or emotional stimulus. It is not
always a bad influence, but it can interfere with your health or physical
state (for example: heart rate).
Fatigue can be a symptom of long-term stress, defined as physical or
mental exhaustion. Fatigue dulls your senses, thought processes and
reflexes.
Stress theory
Stress/Fatigue can be measured by following variations in heart rate.
This is calculated based on variations of time between two heart
beats.
The Leap Ware will periodically assess the variation of time between
two heart beats and display an alert if stress to detected.
Low heart rate variability indicates you are under high stress, while a
higher heart rate variability indicates lower stress.
