How many calories does someone burn playing basketball for an hour?

Approximately 500 - 700 calories.

Explanation:

Sports like basketball burn quite a lot of calories as it requires too much of physical exertion.

But to know exactly how much of the calories are burned while a specific physical activity is carried out somehow depends on the weight of the person and that how vigorously that person has been practicing it.

However, we can estimate about 500 - 700 calories to be burned in an one hour game of basketball.
