Explanation of exercise concepts
Calories reflect a person’s daily activity level. The watch presents Active calories and Total calories in your daily activity status and exercise reports.
Active calories refers to calories that people consume in addition to basal metabolism, and doesn’t include basal metabolic consumption. The concept of active calories makes it easier to set your own calorie goals for daily activity/workout consumption, and to evaluate the achievement of your goals.
Total calories refers to the overall consumption including basal metabolism.
VO₂ max refers to the maximum amount of oxygen that a person can ingest to support exercise while performing high-intensity aerobic exercise. VO₂ max is an important indicator reflecting the body’s capacity for aerobic exercise; the larger the VO₂ max, the higher the intensity and the longer the aerobic exercise.
A person’s VO₂ max is affected by a variety of factors, including both innate genetic factors and the improvement brought about by acquired training exercises, as well as age and environmental factors. But in general, regular and high-level aerobic exercise can increase your VO₂ max.
The watch adopts FirstBeat’s industry-recognized VO₂ max measurement method. It can accurately measure the user’s VO₂ max in running, walking, and other exercise modes.
Exercise recovery time
Every exercise consumes energy that needs to be restored through rest. When you body hasn’t fully recovered, another high-intensity workout may cause injuries to your muscles, bones, or ligaments, or impair the functioning of other organs.
Exercise recovery time is an assessment of the intensity of a workout, the consumption of physical resources by that workout, and the current state of your body, to arrive at the time required to fully recover from your workout.
The watch shows the user the real-time cumulative effect of the exercise up to the moment during the workout, which is a good reminder for the user to master their amount of exercise.
