Physical Indicators for Workouts

Watch provides various physical indicators for workouts as evaluation scores. View in workout records or Workout Status app: current training load, total recovery time, VO2max, training effect. Detailed explanation in Workout Status app.

TE (Training Effect)

Measures workout effect on improving aerobic capacity. Score ranges 0.0-5.0. Higher score indicates greater intensity and body load, but better TE. Consider if body load is too high when TE reaches 5.0.

TE score evaluated based on profile, heart rate, and speed. Low TE score doesn't indicate a problem, but that workout was too easy. View TE score and suggestions after workout, or review in records.

Workout Status

Includes current training load, full recovery time, and VO2max. Determined by profile and data like heart rate. Accuracy improves as watch understands and analyzes body/workout data.

VO2max

Indicates oxygen consumed during max-intensity workouts, important for aerobic capacity. Prerequisite for high-level aerobic capacity in endurance athletes. Personal indicator with different standards for gender/age. Watch evaluates athletic capacity based on profile, heart rate, speed. VO2max changes with athletic capacity, varies by individual body conditions.

How is it obtained?

1. Correctly enter profile in app.
2. Run outdoors for at least 10 minutes wearing watch, ensuring heart rate reaches 75% of max heart rate.
3. After run, view current VO2max in watch's workout record app or 'See more statuses' screen.
4. VO2 Max values map to seven athletic ability levels: Novice, Elementary, Ordinary, Medium, Good, Excellent, Superior.

How can I view it?

View current VO2max in watch's workout status app. View VO2max history and variation trends in app.

Training Load

Calculated based on excess post-exercise oxygen consumption (EPOC). Higher score indicates longer workout time and greater intensity. Total training load calculated over past 7 days, representing burden from recent workouts. Three training load ranges: low, moderate, high.

• Low: Won't improve athletic ability much.
• High/Too High: May cause fatigue, not conducive to improvement, injury risk.
• Moderate: Recommended for continuous athletic ability improvement within tolerance range.

Moderate range depends on recent and long-term workout data, becoming more accurate with use.

How to obtain training load:

After workout mode enabled, obtain training load of current workout upon reaching minimum training load level. Past 7 days' training load viewable in watch's workout status app.

How to view the training load:

View in watch's workout status app. View historical training load and change trends in app.

Total Recovery Time
