The Garmin Forerunner 945 is a premium GPS smartwatch designed with the needs of dedicated runners and triathletes in mind. A growing number of aspects of performance and environment are identified, scientifically analyzed, and interpreted to help you become a better, faster, more dynamic athlete.
The Garmin Forerunner 945 is the first GPS smartwatch to feature Firstbeat’s Heat and Altitude Acclimation feedback. Transitioning to a more challenging environment triggers physiological adaptations that help you perform better at your new higher elevation, or in hotter and more humid climates. The ability to recognize and account for how environmental factors impact your performance provide are an essential contribution of 6th generation VO2max fitness detection analytics. It also makes it possible to keep you informed on how well acclimated you are to the specific demands of your current environment.
The Garmin Forerunner 945 builds on the success its predecessor in many areas. Two years ago, the Garmin Forerunner 935 introduced the Training Load and Training Status data screens. The former keeps tabs on the physiological impact of your activities and helps guide you towards a degree of challenge that’s ideal for you based on your fitness level and activity history. The later examines trends in your training load in light of changes in your cardiorespiratory fitness to reveal the productivity of your efforts.
Adding to these insights is the new Training Load Focus screen designed to help you guide your efforts in increasingly smarter ways. It empowers you to look below the surface of your activities to understand how they were produced. Three physiologically meaningful types of effort (high-intensity aerobic, low-intensity aerobic, and anaerobic) are recognized in real time during your activities and are quantified in terms of they contributed to your total Training Load over the past four weeks.
When your Training Load and Load Focus are both optimal and balanced, it means that you are on your way towards better fitness, performance capacity, and well-prepared for whatever challenge arises. With a strong, well-balanced foundation in place, you can confidently turn your focus toward the specific types efforts that align with your personal performance goals.
Shown on the summary screen at the end of your activities, color-coded Workout Labels are another new feature on the Forerunner 945. These short, descriptive labels are calibrated to reveal the primary benefit of your completed workout in terms of how it supported or developed a specific aspect of your performance capacity. No more guesswork about which workouts stimulated Recovery or enhanced your endurance Base. Tempo runs or rides are recognized along with those that raise your Lactate Threshold and others that improve that your VO2max. Interval workouts built from sprints and bursts of high-intensity work mixed with recovery periods are identified and labeled based on contributions to Anaerobic performance capacity and Speed development.
In addition to the primary benefit Workout Label and Aerobic and Anaerobic Training Effect feedback, you will also be able to see for the first time how much each activity you record contributes to your overall Training Load.
Recovery Time estimates now take special situations into account that are known to influence the amount of time it takes you to bounce back. These special situations include exceptionally challenging workouts (e.g., a hard run with substantially higher Training Effect score than your normal workouts) and significant changes in your acute (7-day) to chronic (4-week average) training load ratio.
Race Time Predictions offer a smart prediction of how long it will take you to run popular race distances (5k, 10k, half-marathon, and marathon). Previously calculated entirely based on a combination of your VO2max and performance intensity sustainability guidelines, the new analysis incorporates valuable new data into the prediction model. Key elements include trends in your weekly mileage and training load with particular attention to your longer endurance runs.
Better fitness and personal well-being are about more than just recording your workouts. Like its predecessor, the Garmin Forerunner 945 delivers 24/7 stress monitoring. All-day Stress tracking is based on a scientific analysis of heart rate variability that reveals the back-and-forth activity between the sympathetic (fight-or-flight) and parasympathetic (rest-and-digest) branches of your autonomic nervous system.
Where the Forerunner 945 improves on its predecessor is with the inclusion of Body Battery, a novel presentation that brings the impact of physical activity, stress, recovery, and the restorative power of sleep come together in a single place. You can observe and manage your energy levels throughout the day, see when you are ready to benefit from a challenge and when taking it easy and resting up might be the best option.
