| Max Bike Cadence (rounds/min) | Maximum bike cadence captured during the activity, in rounds per minute. |
| Num. of active Lengths | Number of active length provided by Garmin Activity API. |
| Starting Lat | Latitude of activity start. |
| Starting Lng | Longitude of activity start. |
| Total Elev. Gain (m) | Total elevation gain during activity, in meters. |
| Total Elev. Loss (m) | Total elevation loss during activity, in meters. |
| Is Parent | Indicates whether the activity is a parent activity with sub-activities (e.g. triathlon activity consists of running, swimming and cycling). |
| Parent Summary Id | Indicates id of parent activity. |
| Manual | Indicates (true/false) whether activity was recorded manually. |
| Device Name | Used wearable model. |
| Red Zone (s) | Time spent in zone in seconds. see heart rate zones for details. |
| Red Zone (%) | Time spent in zone in percentage. see heart rate zones for details. |
| Anaerobic Zone (s) | Time spent in zone in seconds. see heart rate zones for details. |
| Anaerobic Zone (%) | Time spent in zone in percentage. see heart rate zones for details. |
| Aerobic Zone (s) | Time spent in zone in seconds. see heart rate zones for details. |
| Aerobic Zone (%) | Time spent in zone in percentage. see heart rate zones for details. |
| Fat Burn Zone (s) | Time spent in zone in seconds. see heart rate zones for details. |

| Record Id | Unique identifier of the Dexcom event record. |
| System Time | Timestamp of the event on the Dexcom system clock. |
| Display Time | Timestamp of the event as shown on the user's Dexcom display device. |
| Event Status | Status of the Dexcom event. |
| Event Type | Type of the Dexcom event (e.g. glucose alert, insulin, carbs, exercise). |
| Event Sub Type | Sub type of the Dexcom event. |
| Value | Value of the event (unit given in the Unit column). |
| Transmitter Id | Identifier of the Dexcom transmitter. |
| Points | Points measure activity relative to the participant's basal metabolic rate (BMR): Points = (Calories - BMR) / BMR x 100. The BMR is calculated from the profile data with the Mifflin-St Jeor formula (weight height age sex). |
| Transmitter Generation | Generation of the Dexcom transmitter (e.g. G6, G7). |
| Display Device | Device on which the Dexcom data is displayed (e.g. receiver, phone). |
| Gyroscope | Measures angular velocity along 3 orthogonal axes x, y and z. The output is degrees/second. Resolution is fixed at 32Hz (i.e. 32 measurements per second). Garmin wearables do not support adjusting this resolution. Recording is 24/7. It is not possible to schedule or start/stop recording. Each user will produce 2.76 Mio. measurements per day. Accelerometer data generates approx. 720KB/hour (16.87MB/day). Data export is only available as csv or json file format. XLS is not support as MS Excel cannot open such large amounts of data. You need a code/text editor. Fluctuations in recording frequency may occur and are normal due to error tolerances of the hardware. |
| Accelerometer | Measures acceleration along 3 orthogonal axes (x, y and z). The output is milli-g units. Resolution is fixed at 25Hz (i.e. 25 measurements per second). Garmin wearables do not support adjusting this resolution. Recording is 24/7. It is not possible to schedule or start/stop recording. Each user will produce 2.16 Mio. measurements per day. Accelerometer data generates approx. 562.5KB/hour (13.18MB/day). Data export is only available as csv or json file format. XLS is not support as MS Excel cannot open such large amounts of data. You need a code/text editor. Fluctuations in recording frequency may occur and are normal due to error tolerances of the hardware. |
