Lactate test analysis online
Enter values from Lactate Pro 2, Lactate Plus, Lactate Scout or Lactate Express and calculate LT1, LT2, curve and zones.You measure lactate with Lactate Pro 2, Lactate Plus, Lactate Scout or Lactate Express. LactateThreshold turns pace, watts and mmol/L values into a traceable analysis with curve, thresholds, VLamax estimate and concrete training ranges.
Values you enter
- Pace or watts for each stage
- Lactate value per stage in mmol/L
- Optional: heart rate, RPE, stage duration and body weight
Analysis you get
- Lactate curve with plausibility check
- LT1 and LT2 with method comparison
- VLamax estimate and metabolic context
- Training zones for pace, watts and heart rate
Example: six measurements become thresholds and zones
This is what people expect from lactate test analysis: raw measurements in, interpretable training decisions out. The example shows a cycling step test with watts, lactate and heart rate.
| Stage | Power | Lactate | HR |
|---|---|---|---|
| 1 | 140 W | 1.2 mmol/L | 128 |
| 2 | 170 W | 1.5 mmol/L | 139 |
| 3 | 200 W | 2.0 mmol/L | 151 |
| 4 | 230 W | 2.8 mmol/L | 162 |
| 5 | 260 W | 4.1 mmol/L | 173 |
| 6 | 290 W | 6.7 mmol/L | 184 |
From test to training decisionFrom step test to training decision
Measure
Record lactate at the end of each stage and note test conditions.
Check
Curve shape, outliers and stage logic become visible.
Calculate
Several threshold models provide LT1, LT2 and method spread.
Apply
Zones and pacing are translated into pace, watts and heart rate.
Why you can trust the analysis
LactateThreshold does not turn measurements into false precision. The app shows the curve, method comparison, plausible thresholds and the limits of your test protocol transparently.
Why this page targets "lactate test analysis"
The search intent is specific. People have already measured values or are planning a test and need the actual analysis. This page therefore links directly to data entry, protocol, methodology and device-specific pages.
In-depth guides for lactate test analysis
These pages expand the topic cluster and help users with concrete questions before, during and after the test.
Frequently asked questions
Can I analyze a lactate test at home?
Yes. If you have intensity or pace for each stage and the measured lactate value in mmol/L, you can analyze the values online. LactateThreshold calculates lactate curve, LT1, LT2, VLamax estimate and training zones.
Which lactate meters work with the analysis?
The analysis works with any portable lactate meter that reports mmol/L values, including Lactate Pro 2, Nova Lactate Plus, EKF Lactate Scout Sport and Lactate Express.
Is the analysis free?
The basic analysis with lactate curve, thresholds and training zones can be tested for free. Premium functions such as advanced reports and coach workflows are optional.
What is the difference between LT1 and LT2?
LT1 marks the first relevant rise in lactate production and is important for easy endurance work. LT2 is closer to the highest controlled sustainable intensity and guides threshold training and pacing.
Is a fixed 4 mmol/L value enough?
A fixed 4 mmol/L value can be a reference, but it does not fit every athlete. That is why LactateThreshold compares methods such as Mader, Dmax, Modified Dmax, Dickhuth, Log-Log and Delta models.
Analyze your own lactate values
Enter pace or power and your measured lactate values. LactateThreshold calculates lactate curve, LT1, LT2, VLamax and training zones.
