The Garmin vívosmart 4 was introduced as the newest addition to the company’s popular line of fitness trackers today at IFA 2018 in Berlin. Designed to enhance and promote healthy and active lifestyles, the vívosmart 4 raises the bar by offering insight into wearer energy levels for the first time. This new capability comes in the form of Garmin’s new Body Battery™ concept powered by the Firstbeat physiological analytics engine.
Introducing Body Battery™ and the Science of Stress Tracking
Since its debut aboard the vivosmart 3 in 2017, All-day Stress Tracking has become a signature feature of Garmin’s vívo, Forerunner and fēnix series devices. Building on this success, Body Battery™ takes stress and recovery insight to the next level with the goal of helping people make better training, rest, and sleep decisions.
“The degree of benefit you receive from a tough workout, productivity in the workplace, and personal well-being share a common thread,” says Aki Pulkkinen, Firstbeat head of consumer technology. “As humans our physiological resources are limited, and success depends on how effectively we use the energy we have. The feedback you get from Body Battery helps direct your efforts to maximize your potential.”
When your Body Battery™ is full, your energy levels are high. You are well-rested and primed to thrive. Throughout the day the combined impact of physical activity and stress deplete your energy stores and drain your Body Battery™. Restful moments during the day give you a boost, but a good night’s sleep is your best opportunity to recharge your Body Battery™ to full capacity.
The scientific foundation of Garmin’s stress tracking and Body Battery™ features comes from Firstbeat’s ability to analytically recognize and interpret beat-to-beat changes in your heart function, a phenomenon known as heart rate variability (HRV).
Analysis of HRV is used to reveal interplay between the sympathetic (fight-or-flight) and parasympathetic (rest-and-digest) branches of the autonomic nervous system as they work to meet the demands of life. As a result, moments of stress and rest throughout the day can be pinpointed and measured.
Fitness Tracking and Fitness Age
To provide this vital feedback, Firstbeat uses a combination heart rate, movement speed, and other key data to reveal how effective your body is at utilizing oxygen to produce energy aerobically.
This information is also used to calculate Fitness Age, a relatable interpretation of VO2max based on global norms for age and gender. Regular physical activity at the right level of intensity holds the key to increasing your VO2max, restoring vitality, and reducing your Fitness Age.
Easy access to your current fitness level means no more guess work. You can see whether you are fit enough to achieve health benefits and your performance goals. Tracking changes in your fitness level over time can also provide a powerful source of motivation to keep things going in the right direction.
Garmin’s most fashionable activity wristband tracker to date, the ultra-slim vívosmart 4 blends smarts with style, and is available in multiple colors with metal trim accents in silver, gold and rose gold. The vívosmart 4 has a suggested retail price of $129.99.
