How this is worked out
- Take the MET value for tennis from the 2024 Adult Compendium of Physical Activities: MET 6.4, the median of its 6 measured variations (MET 4.5–8).
- Convert MET to a rate using the ACSM relationship: multiply by 3.5, then by body mass in kilograms, then divide by 200. That gives kilocalories per minute.
- Multiply the rate by the number of minutes actually spent.
- Round to whole kilocalories. Nothing else is applied — no age factor, no sex factor, no proprietary adjustment, because the underlying data does not support one.
kcal/min = MET × 3.5 × mass(kg) ÷ 200 kcal = kcal/min × minutes 6.4 × 3.5 × 70 ÷ 200 = 7.84 kcal/min 7.84 × 15 min = 118 kcal

A number this clean is a model. It does not know your gradient, your gear, the wind, or how hard you were actually trying.
