Caloric expenditure during deep-water exercise can vary between:

Caloric expenditure during deep-water exercise is influenced by various factors, including the intensity of the exercise, the individual’s body composition, and the specific movements performed during the workout. The range of 8.8 to 18.9 kilocalories accurately captures the typical variation in caloric burn associated with such activities.

Deep-water exercises, often involving resistance and buoyancy, engage multiple muscle groups and can require significant energy, resulting in a caloric expenditure that falls within this range for many individuals. This number reflects the energy cost associated with moderate to vigorous intensity exercises performed in deep water, where the resistance can lead to higher energy use compared to exercising in shallow water or on land.

The other options provide ranges that either understate or overstate typical caloric burn for deep-water activities, making option B the most accurate choice based on common physiological responses to such exercises.
