Name: Aerobic (HR zone) timer
Author: Trudelta

This data field was originally developed to determine if one has reached the heart rate zone criteria for getting a VO2max measurement.  For this it measures the maximum continuous duration spent in heart rate zone 3 (aerobic) or higher.  Depending on the activity type and the Garmin watch model, the required continuous duration in zone 3 or higher may be 10, 15 or 20 minutes in order to get a VO2max measurement.

I since expanded this to be a configurable timer for target heart rate zone.

# Features
* Measure maximum continuous or cumulative duration spent in target heart rate zone(s)
* Configurable target zone(s)
* Vibrate alert when minutes goal in the target zone has been reached

# FULL Version Features
* Saves the duration spent in the target heart rate zone(s) to the session record in Garmin Connect
* Saves a chart of the HR zone vs. time to the session record in Garmin Connect.
* Determines heart rate recovery at the end of the activity and saves this for viewing with the activity in Garmin Connect.  To use this, press STOP as usual at the end of your exercise.  Rest.  At the end of the 2 minutes, the watch will vibrate, indicating that the heart rate recovery has been measured.  Now save the activity. View the results in Garmin Connect.  For example, a heart rate recovery value of 25 means that your heart rate dropped 25bpm after 2 minutes.  This value should increase as your fitness level improves.
* Determines VO2max adjustment for altitude and saves this for viewing with the activity in Garmin Connect. This is useful for Garmin models that do not have the altitude acclimation feature.  For example, if the VO2max adjustment value is 5%, then the VO2max reported by Garmin should be multiplied by 1.05 to estimate your VO2max at sea level.

Aerobic (HR zone) timer

此数据字段最初是为了确定用户是否已达到获取最大摄氧量 (VO2max) 测量所需的心率区标准而开发的。为此，它会测量在心率区 3（有氧）或更高区域停留的最长持续时间。根据活动类型和 Garmin 手表型号，在心率区 3 或更高区域停留所需的最长持续时间可能是 10、15 或 20 分钟，才能获得最大摄氧量 (VO2max) 测量值。

我后来将其扩展为一个可配置的目标心率区计时器。

# 功能
* 测量在目标心率区停留的最长连续或累计持续时间
* 可配置的目标区
* 达到目标区分钟数目标时发出振动提醒

# 完整版功能
* 将在目标心率区内所花费的时间保存到 Garmin Connect 中的会话记录中
* 确定活动结束时的心率恢复情况，并将其保存，以便在 Garmin Connect 中与活动一起查看。要使用此功能，请在锻炼结束时像往常一样按下“停止”按钮。休息。2 分钟后，手表将振动，表示已测量心率恢复情况。现在保存活动。在 Garmin Connect 中查看结果。例如，心率恢复值为 25 表示您的心率在 2 分钟后下降了 25 次/分。随着您的体能水平提高，此值应该会增加。
* 确定最大摄氧量 (VO2max) 的海拔高度调整值，并将其保存，以便在 Garmin Connect 中与活动一起查看。这对于不具备海拔适应功能的 Garmin 型号非常有用。例如，如果最大摄氧量 (VO2max) 调整值为 5%，则应将 Garmin 报告的最大摄氧量 (VO2max) 乘以 1.05 以估算您在海平面的最大摄氧量。注意：如果您的手表型号已具备海拔高度补偿功能，请忽略此操作，无需调整 Garmin 报告的最大摄氧量。
