WinLactat ยท Hybrid performance diagnostics

Your CPET system shows the breathing.
WinLactat shows the whole picture.

WinLactat takes the measurement data from your CPET system and combines it with your lactate values in a single analysis: ventilatory and metabolic thresholds at a glance, training zones from both data sources and a report that explains both.

What you gain

Respiratory plus metabolic: the 360ยฐ view of your athletes

Your CPET system measures the respiratory side of exercise: how much oxygen is taken up and how much carbon dioxide is released. Lactate shows the metabolic side: what happens in muscle metabolism. WinLactat analyzes both together โ€“ only this combination gives the complete picture of performance capacity.

Respiratory ยท CPET

How the body breathes and uses oxygen

  • V'Oโ‚‚, V'COโ‚‚, V'E, RER, ventilatory equivalents
  • VOโ‚‚max and ventilatory thresholds VT1 / VT2
  • Energy expenditure and substrate utilization from gas exchange data
Metabolic ยท Lactate testing

What happens in muscle metabolism

  • Lactate curve across all exercise stages
  • Lactate thresholds according to Mader, Dickhuth, Stegmann and many more
  • VLaMax and MaxLaSS (Professional plan and above)
WinLactat

The 360ยฐ view

  • Ventilatory and lactate thresholds compared side by side
  • Energy expenditure based on both systems
  • Training zones and training plans from both data sources
  • One report that explains both

Combined performance diagnostics: lactate and CPET with WinLactat

Presented live at the mesics booth at the Sports Medicine and Health Summit 2025 in Hamburg.

Side by side

CPET alone

  • Ventilatory thresholds (VT1, VT2) โ€“ without lactate thresholds for comparison
  • Lactate values, if collected, end up on paper or in a second spreadsheet
  • Training zones from a single data source
  • Training guided by thresholds that cannot be checked during training
  • You have to piece together progress comparisons yourself
  • Report in the device manufacturerโ€™s layout

CPET + WinLactat

  • Ventilatory and lactate thresholds in one chart โ€“ independent and flexible
  • Gas exchange, heart rate and lactate values in one dataset per test
  • Training zones based on power, heart rate, lactate or e.g. RQ
  • Individual training plans with lactate target values that can be measured during training itself
  • Longitudinal and cross-sectional comparison of any number of tests, including ventilatory parameters
  • Your own report with your logo โ€“ as PDF or Word
More than an analysis

From test to training plan โ€“ tailored and ready to use

CPET ends with the findings. WinLactat goes further: every test yields individual training zones and a complete training plan that controls intensity and volume day by day.

  • Field-tested templates โ€“ training plans at the push of a button, e.g. for base building, running or marathon; you can create your own templates yourself.
  • Individual from every test โ€“ the same template produces a separate plan for each athlete, with matching power, heart rate and lactate zones.
  • Cycles and calendar โ€“ training sessions, cycles and overall goal, output as a calendar.
  • Intensity your way โ€“ zones based on power, heart rate, lactate or CPET parameters.
The advantage in everyday training

Ventilatory thresholds stay in the lab. Lactate can be measured anywhere.

Whether someone is training at VT1 or VT2 is hard to verify without gas exchange analysis. Lactate, on the other hand, can be measured in every session with a portable meter. Because WinLactat also outputs every training zone as a lactate target value, your athletes can check for themselves at any time whether they are training in the right zone.

Reasons to Buy

Eight reasons to connect your CPET system with WinLactat

For sports medicine practices, institutes, performance centers and clinics that already test ventilatory parameters โ€“ and want to get more out of every test.

01

Two threshold concepts, one comparison

VT1/VT2 from respiration and lactate thresholds according to Mader, Dickhuth, Stegmann and many more, directly overlaid โ€“ determined independently, freely comparable.

02

No more manual data entry

Your systemโ€™s gas exchange export is imported โ€“ all channels automatically land in the right test, ready for analysis.

03

No new hardware required

You already have your CPET system. WinLactat uses it as it is โ€“ no system change and no investment in new devices.

04

Wasserman, just as you know it

9-panel plot, custom panel views and a report designer for your CPET report sheets.

05

Energy expenditure: measured, not estimated

Using CPET data, WinLactat calculates the actual energy expenditure at the thresholds and in every training zone.

06

Training plans that work in everyday practice

Individual plans from proven templates โ€“ with lactate target values your athletes can check for themselves during training.

07

Progress over years

Longitudinal and cross-sectional test comparison, team rankings, polar charts โ€“ including ventilatory parameters.

08

Fits your IT

Multi-user, server-ready database, GDT and HL7 integration with practice and hospital systems. Your data stays in-house.

Seamless with JAEGER

Your JAEGER system delivers the gas exchange data. WinLactat turns it into a 360-degree performance report.

WinLactat has a dedicated importer for JAEGER data. It transfers not only the measurement channels but also the anaerobic threshold set in the JAEGER system and the warm-up, exercise and recovery phases. So you continue your analysis exactly where you left off in the CPET test.

In the free product onboarding session, we set up the export together with you โ€“ tailored to your device and your software version.

Frequently asked questions

Good to know

Do I need to replace my CPET software?

No. WinLactat is an extension to your CPET software. Nothing changes: you keep measuring with your system and hand the data over to WinLactat with one click. There, lactate, the combined analysis, training zones, training plans and the report are added.

Which data does WinLactat take from the CPET system?

Depending on the system, the stage-based or breath-by-breath channels such as V'Oโ‚‚, V'COโ‚‚, V'E, RER, breathing rate, heart rate, energy expenditure and workload. With the JAEGER import, the anaerobic threshold and the test phases are transferred as well.

My device is not on the list โ€“ what now?

WinLactat also reads Excel, CSV and text files via a generic import with channel mapping. In a personal demo, we will show you the import using your own data.

Who is eligible for the JAEGER offer?

All institutions that operate a JAEGER CPET system โ€“ especially users of the Vyntus CPX and the Vyntus ONE with CPET option (SentrySuite software), as well as users of older systems such as Oxycon Pro, Oxycon Mobile or MasterScreen CPX. Your device was purchased under the name Vyaire, CareFusion or VIASYS? No problem โ€“ what counts is the system, not the company name on the invoice. We verify your proof (serial number, customer number or invoice number) and then activate your access.

What happens after the 3 months?

The trial license ends automatically; no costs are incurred. If you would like to continue, we will send you a quote โ€“ your data and analyses are retained.

How does the product onboarding session work?

Online via video and screen sharing, 60 minutes, with our sports scientist. We set up the import of your JAEGER export, create a sample test and show you the analysis, training zones and report.

Where is my data stored?

Exclusively with you. WinLactat runs locally on your computers or your server โ€“ no cloud, no external servers and no third-party data processing on your behalf. Your measurement data never leaves your premises and remains entirely within your own IT infrastructure. The database supports multiple users and can be connected to practice and hospital systems via GDT or HL7.

Terms of participation (summary)

The offer is aimed exclusively at companies and institutions (B2B) that operate a JAEGER-brand CPET system. One trial license per institution for up to 3 workstations; term of 90 days from the product onboarding session, but starting no later than the 30th day after activation; the license ends automatically. The product onboarding session (60 minutes, online) must be taken within the term. Participation requires verifiable proof; mesics reserves the right to decline requests without proof. The offer is valid until March 31, 2027. There is no entitlement to conclude a paid license, nor is there any obligation to do so.
