Hybrid diagnostics: lactate and gas exchange in one analysis

Your CPET system shows the respiratory side of exercise, lactate shows the metabolic side. WinLactat brings both together – for a complete picture of performance capacity.

  • Import from your CPET system – breath-by-breath and threshold data from JAEGER, COSMED, CORTEX, GANSHORN and others
  • Ventilatory and lactate thresholds in one chart – independent and flexible
  • Wasserman 9-panel plot – with panel designer and custom reports
  • Energy expenditure measured, not estimated – plus VLaMax and MaxLaSS

Frequently asked questions

Good to know

Which edition is right for me?

For pure lactate diagnostics, Basic is all you need. If you also run a CPET system, Professional is the right choice – it includes import and analysis of gas exchange data. Hospitals, labs and performance centers with multiple workstations and integration into their IT choose Clinical & Performance. In a short demo, we’ll find the right edition together.

What can the free trial do?

Everything. The free trial is the unrestricted full version with all features of Professional and Clinical & Performance – including CPET import and hybrid analysis. You work with your own data from the start. The trial runs for 14 days; if you decide on WinLactat, we activate your license.

How many workstations can I use?

From the Clinical & Performance edition, WinLactat has unlimited multi-user capability: any number of workstations access one shared database on the network, via a server if you prefer. For field tests and on the go, WinLactat runs portably on the coach’s laptop.

Does WinLactat also run on a Mac?

WinLactat is Windows software. On a Mac, it runs in a Windows environment, for example with Parallels Desktop.

Where is my data stored?

Exclusively with you. WinLactat runs locally on your computers or your server – no cloud, no external servers and no third-party data processing.

Which devices can I connect?

Lactate meters such as Metabol Pro and Lactate Express, CPET systems from JAEGER, COSMED, CORTEX, GANSHORN, ZAN, GERATHERM and Innocor, treadmills from h/p/cosmos, the RBM Cyclus 2 cycle ergometer, Polar heart rate data, and practice and hospital systems via GDT and HL7. In addition, there is import from the Lactate Express App and a generic import for Excel, CSV and text files.

What do I need to use WinLactat?

A Windows PC – for multiple workstations, a network with a shared database on a server or workstation PC. You transfer your lactate values directly from your meter, via Bluetooth or by manual entry. For hybrid analysis, you also need the export from your CPET system.

Can WinLactat import data from my CPET system?

Yes, from the Professional edition upward. WinLactat reads the exports from JAEGER, COSMED (Quark CPET, Omnia, Fitmate), CORTEX MetaLyzer, GANSHORN LF8, ZAN, GERATHERM Blue Cherry and Innocor – gas exchange channels, heart rate, workload and, depending on the system, thresholds and test phases as well. The interfaces have been in use for many years. For other systems, there is a generic import for Excel, CSV and text files.

Do I need WinLactat for Metabol Pro or Lactate Express?

No. Both meters work on their own and with the Lactate Express App included with them. WinLactat is the professional software for in-depth analysis: threshold models, training zones, training plans, reports and progress comparisons. You can transfer readings from the Lactate Express App directly into WinLactat.

I’m just starting my own business – is WinLactat already worth it for me?

Especially then. With our founders program, qualified founders from sports science and sports medicine can use WinLactat free for up to 365 days – and we advise you on building your performance diagnostics. That way, you only invest once your business is viable. To the founders program →

How can I get to know WinLactat?

In a personal online demo with our sports scientist, in our workshops or directly with the free trial. JAEGER users get 3 months free and a one-hour onboarding session.
