Field Lactate testing

Lab grade performance testing, but in the real world.

Lab testing offers great accuracy and reproducibility. Field tests on the other side provide data which better reflect real world scenarios, but might be limiting in quantity and quality of results.

Now you can have both: lab grade accuracy and quantity of data, in real world conditions.

Lab accuracy, field reality

Now you can have your cake and eat it.

What a lab gives you, what a field test gives you, and what changes when the field test runs through INSCYD.

Everything, from one field test

A complete lab level assessment.

One field test returns the full picture: VO₂max, VLamax, anaerobic and aerobic power, substrate utilization, lactate accumulation and recovery, thresholds and physiology based training zones. The same metrics a laboratory would hand you, from a test your athlete rides, runs, rows or swims in their own environment.

Adapt the protocol to your needs, not the other way around.

For a full performance assessment you can choose different combinations of efforts and protocols as you need it. For lactate testing it takes a few submaximal and at least one all out effort. That is it, no more restrictions. Want longer efforts? Efforts of different durations? Only all out efforts? Add Sprints? Spread over different training sessions or days? No problem, you design the protocols to your need.

Unsure what is best for you? We have got you covered: we have pre-set protocols and a dedicated customer support team to design protocols for your needs.

Comparable results

Your data is reproducible, even if the test isn’t.

Conventional lactate testing leaves you alone with one major problem. Test results from tests which are not done by the same protocol, the same step duration and increment, will result in different lactate curves and are therefore not comparable.

INSCYD solves this problem: all tests you do will be directly comparable. No matter what the protocol was, all results can be compared to each other.

The same athlete, three protocolsProtocol 1
raw lactate curveINSCYD profile

Switch the protocol. The raw curve moves. The INSCYD profile does not.

Real-world testing

Wind, snow, temperature, current. INSCYD got you covered.

You test in sports such as XC skiing, canoeing, skating, rowing, or similar sports in which the conditions seem to render the possibility to get absolute numbers impossible? No problem when you test with INSCYD. Independent of the conditions you test in, and of how these might affect the speed of the athlete, your results stay accurate and comparable from one test to the next.

WindCurrentTemperatureSnowAltitude

With INSCYD your test results become totally independent of the conditions. Test today in cold temperature and windy conditions, and in warm and mild conditions later? You will be able to compare the results 1:1, no caveat, no limitations.

Every metric that matters

One assessment. The complete picture of your athlete’s physiology.

VO₂max, VLamax, FatMax, thresholds, fuel use and training zones, from a single test in the lab, in the field or fully remote.
