Researchers show that exercisers can burn as many as 200 calories in only 2.5 minutes by incorporating sprint interval training, dramatically cutting the time needed for a work-out.Food energy is measured in kcal or kilocalories.
In this new study conducted by a team from the University of Colorado Anschultz Medical Campus and Colorado State University, researchers compared volunteers' energy disbursement on two separate days, one on which they completed a sprint interval workout on a stationary bicycle. Conclusions showed a slight increase in the amount of calories that were burned on workout day, regardless of the short amount of time spent doing authentic strenuous exercise.
A kilocalorie or Calorie is 1000 calories.
Note the capital "C."
That is how you tell one from another.
On average one burns 100 Calories traveling 1 mile on foot.
On average one burns about 29 Calories traveling one mile on a bike.
To burn 200 Calories in 2.5 minutes, one would have to ride a bike about 7 miles or at a speed of 2.8 miles per minute. This is 168 miles per hour.
200 calories is an absolutely negligible amount to burn.
