Are Players Actually Getting Fitter?
You’re testing fitness… but missing what happens in between.
Most teams only test fitness occasionally throughout the year, but what happens to player fitness across a long season?
By conducting regular submaximal fitness testing with your athletes, you can track changes in cardiovascular fitness without the need for demanding maximal protocols, giving you ongoing insight to adjust training, both at a team level and individually.

Fitness Monitoring in Team Sports Has Never Been Easier
Stop processing test data manually. Monitor fitness in real time and access the results as soon as the test ends.
With Firstbeat, submaximal fitness testing easily becomes part of your weekly workflow, taking just a few minutes to complete from starting the test to seeing the results:
- Players put on the Firstbeat sensor
- Coach selects protocol and starts the test
- See the live heart rate as percentage of HRmax
- Test ends, Heart Rate Recovery is calculated
- Download the data right away from sensors
- Access the report in the Sports Cloud
