Firstbeat is built for broad performance analytics. LactateThreshold focuses on measured lactate step tests and transparent threshold methods.

Firstbeat

Firstbeat estimates or analyzes performance data without being focused on measured lactate step-test interpretation.

LactateThreshold

LactateThreshold takes measured lactate values plus pace or watts and calculates LT1, LT2, VLamax estimate, training zones and method comparison directly in the browser.

Frequently asked questions

Can I use Firstbeat with LactateThreshold?

Yes, as a complement. Use Firstbeat for its own monitoring workflow and LactateThreshold for measured lactate step-test analysis.

Do I need an export or integration?

No direct integration is required. A step test usually has only 6 to 9 measurements, so manual entry takes less than a minute.

What does LactateThreshold add?

It adds lactate curve analysis, LT1, LT2, method comparison, training zones, VLamax context and optional premium reports.

Is this a lab replacement?

It is a structured training analysis tool for valid measurements. It does not replace medical diagnostics or professional supervision when those are required.
