The power meter must be paired with your watch (Pairing Your Wireless Sensors, page 72). 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).
Getting Your FTP Estimate Before you can get your functional threshold power (FTP) estimate, you must pair a chest heart rate monitor and power meter with your watch (Pairing Your Wireless Sensors, page 72), and you must get your VO2 max. estimate (Getting Your VO2 Max. Estimate for Cycling, page 55). The watch uses your user profile information from the initial setup and your VO2 max. estimate to estimate your FTP.
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 72). The device uses your user profile information from the initial setup and your VO2 max. estimate to estimate your lactate threshold.
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 training load and VO2 max. over an extended time period. You can use your training status to help plan future training and continue improving your fitness level. Peaking: Peaking means that you are in ideal race condition. Your recently reduced training load is allowing your body to recover and fully compensate for earlier training.
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.
Pausing and Resuming Your Training Status If you are injured or sick, you can pause your training status. You can continue to record fitness activities, but your training status, training load focus, recovery feedback, and workout recommendations are temporarily disabled. You can resume your training status when you are ready to start training again. For best results, you need at least two VO2 max. measurements each week (About VO2 Max. Estimates, page 54).
