Formula Used
Load from percent: Load kg = Body mass kg × Load percent ÷ 100
Force: Force N = Load kg × 9.80665
Distance: Distance m = Revolutions × Distance per revolution
Work: Work J = Force N × Distance m × Efficiency factor
Interval power: Power W = Work J ÷ Interval seconds
Mean power: Mean power W = Total work J ÷ Total test seconds
Relative power: Relative power W/kg = Power W ÷ Body mass kg
Fatigue index: Fatigue index % = (Peak power − Minimum power) ÷ Peak power × 100
How to Use This Calculator
Enter body mass in kilograms. Choose a resistance method. Use percent load when the braking load is based on body mass.
Enter the revolution counts for each timed interval. A common Wingate setup uses six intervals of five seconds each.
Keep distance per revolution consistent with your cycle ergometer. Use six meters only when that value matches your equipment.
Press the calculate button. Review peak power, mean power, total work, relative power, fatigue index, and interval outputs.

Wingate Test Power Output Guide
What the Result Means
The Wingate test is a short anaerobic cycling test. It often lasts thirty seconds. The rider works against a fixed braking load. Revolutions are counted in equal time blocks. Those counts show how power changes during the effort.
Peak power shows the best short burst. Mean power shows average output across the whole test. Minimum power helps describe the final drop. Relative power divides watts by body mass. This makes athletes of different sizes easier to compare.
Why Interval Data Matters
A single total revolution count can hide useful detail. Five second intervals show the power curve. A strong start with a large fall may show speed strength. A steadier curve may show better fatigue resistance. Coaches can compare repeated tests over time.
This calculator uses load, wheel distance, interval time, and revolutions. It converts the load into force. Then it multiplies force by distance. That gives mechanical work. Dividing work by time gives power in watts.
Good Data Entry
Use the same bike setup each time. Keep saddle height, warmup, load rule, and timing consistent. Record the exact load in kilograms. Check the flywheel distance used by your ergometer. A common Monark setting is six meters per revolution, but equipment can differ.
Body mass should be current. It affects the relative scores. Efficiency correction should stay at one hundred percent unless you have a specific lab reason. Changing it between tests will make comparisons weaker.
Using Results Carefully
Wingate results are sensitive to motivation and pacing. They are also affected by warmup, fatigue, and familiarization. A first attempt may be lower than a later attempt. Use trends, not one value only.
Peak watts help track explosive anaerobic ability. Mean watts and total work help track short duration capacity. Fatigue index shows the percentage loss from highest to lowest interval. It is useful, but it should not be judged alone. A high value can occur with a very high peak.
For best reporting, save the interval table. Include date, body mass, load, interval length, and distance per revolution. This makes the calculation repeatable. It also lets another coach check the result. Clean records make training decisions more reliable after each session.
FAQs
What does peak power mean?
Peak power is the highest interval power reached during the Wingate test. It reflects short burst anaerobic output. It is usually reported in watts and watts per kilogram.
What does mean power show?
Mean power is total work divided by total test time. It shows average output across the entire effort. It is useful for comparing repeated tests.
Why enter interval revolutions?
Interval revolutions reveal how output changes during the test. They allow peak, minimum, cadence, fatigue, and mean values to be calculated more clearly.
What is fatigue index?
Fatigue index is the percentage drop from peak power to minimum power. A higher value shows a larger decline across the effort.
What distance per revolution should I use?
Use the value for your ergometer. Six meters is common for some cycle setups, but your equipment manual or lab protocol should guide this input.
Why use relative power?
Relative power divides output by body mass. It helps compare athletes with different body sizes. It is reported as watts per kilogram.
Can I use custom resistance?
Yes. Choose custom load when your test uses a fixed braking load. Choose percent mode when resistance is based on body mass.
Is this a medical test result?
No. This calculator gives mechanical performance metrics. Use trained supervision and consistent protocols when interpreting athletic or laboratory results.
