Estimate gross calories for active general gymnastics time using the 2024 Adult Compendium’s 3.8 MET value, or reverse the same equation for duration or body weight.
Gymnastics MET Calorie Formula
The calculator uses the standard gross-energy equation with 3.8 MET for general gymnastics. Body weight is converted to kilograms before the relationship is applied.
How the Calculation Works
The selected output is hidden, marked unavailable to assistive technology, disabled, cleared, and made non-required. Only the source values needed for that mode remain visible.
How to Use This Calculator
- Select the missing value in the Solve for menu.
- Enter only the visible source values.
- Select Calculate and review the result and substituted steps.
- Use Reset before starting a different routine or scenario.
Worked Example
At 70.0 kg for 60 active minutes, the estimate is 3.8 × 3.5 × 70 ÷ 200 × 60 = 279.3 gross calories.
Input and Result Guide
| Item | How to use it |
|---|---|
| 3.8 MET | The 2024 Adult Compendium value for general gymnastics. |
| Body weight | Enter kilograms or pounds beside the weight field; pounds are converted internally. |
| Active duration | Count working gymnastics time rather than the full clock time of a rest-heavy session. |
| Gross calories | Includes resting energy during the activity interval and is a population-average estimate. |
| Reverse modes | Duration and body-weight results are algebraic checks of the same equation, not measurements. |
Interpreting the Result
The estimate is most useful for comparing similar sessions recorded with the same active-time method. It is not precise enough to replace measured energy expenditure or individualized nutrition guidance.
Assumptions and Limitations
The Adult Compendium is designed for adults and its standard MET is not individualized. Age, body composition, efficiency, apparatus, routine density, rest, conditioning blocks, and actual intensity can materially change energy use. Do not apply the adult value to children without appropriate youth-specific guidance.
Common Questions
Why did an input disappear when I changed Solve for?
The hidden field is the requested output. Enter the remaining visible values and the calculator will solve for that target.
Will my last successful calculation be restored?
Yes. The calculator saves enabled source values and the successful result in this browser. Reset clears that saved state.
