VO2max Fitness Analysis

Thanks to Firstbeat’s heart-rate analytics engine, you can access your cardiorespiratory fitness level in terms of VO2max. VO2max describes the ability of the body to utilize oxygen to transform nutrients into energy. With VO2max functionality you can access vital physiological information, tailored coaching guidance, gain workout motivation and benefit from the same scientifically personalized training insights used by professional athletes. Designed for athletes who want to enhance their performance and track physiological data, we offer three important training tools:

· Training Effect highlights the impact that specific activities have on the development of aerobic performance capacity.
· Recovery Time recommends downtime between each activity to maximize the benefit of each session.
· Training Load tracks the combined physiological impacts of all activities over the past seven days.
