OT - Please check my calculations
The gym has machines by pulsefitness.
There seems to be a mismatch in the numbers displayed.
After a bike session the summary was:
Power average: 74 Watts.
Time taken: 9 minutes.
Energy used: 50 kcal.
The above energy figure would equate to 333 kcal per hour.
But 100 Watts is only 86 kcal per hour!
The mismatch is so enormous that I feel I must have missed something.
I would be grateful to any physicist who can shed light on the figures.
