Firstbeat for Research

Cutting-edge technology for accurate physiology monitoring to measure and visualize stress, recovery, sleep, and exercise insights in a powerful way.
Firstbeat Science


Pioneer in Physiological Analytics and HRV Analysis

For more than two decades Firstbeat has been a pioneer in the use of physiological analytics to improve sports performance and well-being. Based on years of research we’ve developed an analysis of physiological measures to provide accurate insights into exercise, stress, recovery, and sleep.

To date, sports teams in most competitive arenas are utilizing Firstbeat Sports to optimize the performance of the players. The physiological metrics and data export opportunities combined with Firstbeat sensors allows the same platform to be used in applied physiological research globally.

Firstbeat Life for Research

End-user application

The overall picture of well-being at a glance. Total scores consider the areas of stress and recovery, sleep, and health effects of exercise. Monitor the state and development of your well-being.

Watch in real-time and after each measurement how you respond throughout the day. Identify moments of stress and recovery, the amount and intensity of exercise, and how well you sleep.

After each measurement end-user receives a detailed analysis of their well-being and concrete instructions for the future. The app will also notify if recovery is exceptionally poor.
