These estimates are provided and supported by Firstbeat Analytics™. For more information, go to www.garmin.com/performance-data/running/.
About VO2 Max. Estimates VO2 max. is the maximum volume of oxygen (in milliliters) you can consume per minute per kilogram of body weight at your maximum performance. In simple terms, VO2 max. is an indication of athletic performance and should increase as your level of fitness improves. The Forerunner device requires wrist-based heart rate or a compatible chest heart rate monitor to display your VO2 max. estimate. The device has separate VO2 max. estimates for running and cycling.
Getting Your VO2 Max. Estimate for Cycling This feature requires a power meter and wrist-based heart rate or a compatible chest heart rate monitor. The power meter must be paired with your watch (Pairing Your Wireless Sensors, page 73). If you are using a chest heart rate monitor, you must put it on and pair it with your watch. For the most accurate estimate, complete the user profile setup (Setting Up Your User Profile, page 80) and set your maximum heart rate (Setting Your Heart Rate Zones, page 81).
Heart Rate Variability Status Your watch analyzes your wrist heart rate readings while you are sleeping to determine your heart rate variability (HRV). Training, physical activity, sleep, nutrition, and healthy habits all impact your heart rate variability. HRV values can vary widely based on gender, age, and fitness level. A balanced HRV status may indicate positive signs of health such as good training and recovery balance, greater cardiovascular fitness, and resilience to stress.
Viewing Your Performance Condition This feature requires wrist-based heart rate or a compatible chest heart rate monitor. 1 Add Performance Condition to a data screen (Customizing the Data Screens, page 98). 2 Go for a run or ride. After 6 to 20 minutes, your performance condition appears. 3 Scroll to the data screen to view your performance condition throughout the run or ride.
Conducting an FTP Test Before you can conduct a test to determine your functional threshold power (FTP), you must pair a chest heart rate monitor and a power meter with your device (Pairing Your Wireless Sensors, page 73), and you must get your VO2 max. estimate (Getting Your VO2 Max. Estimate for Cycling, page 27). NOTE: The FTP test is a challenging workout that takes about 30 minutes to complete.
Performing a Guided Test to Determine Your Lactate Threshold This feature requires a Garmin chest heart rate monitor. Before you can perform the guided test, you must put on a heart rate monitor and pair it with your device (Pairing Your Wireless Sensors, page 73). The device uses your user profile information from the initial setup and your VO2 max. estimate to estimate your lactate threshold.

Training Status These measurements are estimates that can help you track and understand your training activities.
Training Status Levels Training status shows you how your training affects your fitness level and performance. Your training status is based on changes to your VO2 max., acute load, and HRV status over an extended time period. You can use your training status to help plan future training and continue improving your fitness level. No Status: The watch needs at least one activity per week, with VO2 max. results from running or cycling, to determine your training status.
Training Load Focus In order to maximize performance and fitness gains, training should be distributed across three categories: low aerobic, high aerobic, and anaerobic. Training load focus shows you how much of your training is currently in each category and provides training targets. Training load focus requires at least 7 days of training to determine if your training load is low, optimal, or high.
About Training Effect Training Effect measures the impact of an activity on your aerobic and anaerobic fitness. Training Effect accumulates during the activity. As the activity progresses, the Training Effect value increases. Training Effect is determined by your user profile information and training history, and heart rate, duration, and intensity of your activity. There are seven different Training Effect labels to describe the primary benefit of your activity.
