Swimming burns more calories per hour than aerobics and cycling.

Answer:

Swimming burns more calories per hour than aerobics and cycling.

Explanation

The statement indicates that when comparing the calorie expenditure of swimming to that of aerobics and cycling, swimming is the most effective in terms of calories burned within the same time frame. This means that if you were to spend an hour doing each activity, swimming would result in a higher total number of calories burned compared to either aerobics or cycling. This can be attributed to the whole-body engagement and resistance of water that swimming entails, which can lead to a more intense workout.
