Everything for Your Lactate Test Analysis
Works with Lactate Pro, Lactate Plus and all other portable lactate meters.
7 Validated Methods
Modified Dmax (Bishop 1998), Dickhuth, Log-Log, Mader, Delta — each with literature references.
Uncertainty Analysis
Bootstrap CIs (±W/pace), R² curve quality, Coverage score — honest measurement uncertainty, not false precision.
LT1-Anchored Zones
Z2 ends at your measured LT1 (San Millán & Brooks 2018), not at a fixed Coggan percentage.
Metabolic Profile
VO₂max × VLamax quadrant chart after Mader & Heck 1986: Sprinter, Power, Diesel or Base?
Race Strategy with CI
IF targets from Allen & Coggan 2019, carbs from Jeukendrup 2014 — with uncertainty propagation.
Progression with Significance
Error propagation checks whether your improvement exceeds measurement noise — 95 %, 68 %, or not significant.
MLSS Calibration
Gold-standard validation: rank all 7 methods against your own MLSS constant test. (Lab tier)
Coach Mode
Manage athletes, team comparisons, invite links, VLamax formula calibration. (Trainer & Lab)

Frequently asked questions about lactate test analysis
Answers to the most important search questions about lactate threshold, step tests, meters and training zones.
Can I analyze my lactate test myself?
Yes. Enter power or pace, lactate values and optional heart rate from your step test. LactateThreshold calculates LT1, LT2, estimated VLamax and individual training zones.
Which lactate meters are supported?
The analysis works with any meter that gives lactate values in mmol/L, including Lactate Pro 2, Lactate Plus, EKF Lactate Scout, Lactate Express and similar portable devices.
What is lactate threshold?
Lactate threshold describes an intensity where lactate production and clearance become important for endurance performance. LT1 helps define easier endurance work, while LT2 is close to your highest sustainable intensity.
How do I run a step test myself?
Start at a low intensity and increase every 3 to 5 minutes, for example by 20 to 30 watts or 20 to 30 seconds per kilometer. Measure lactate at the end of each stage and enter the values.
What do LT1 and LT2 mean?
LT1 marks the transition into measurable lactate accumulation and helps guide Zone 2. LT2 is closer to threshold performance and is central for tempo, FTP and race pacing.
Which calculation methods does LactateThreshold use?
The app compares 7 scientific methods, including Mader, Dmax, Modified Dmax, Dickhuth, Log-Log and delta methods. You see not only one value, but also the methodological spread of your result.
