Research indicates that RPE values for deep water exercise are typically:

The correct answer is that RPE (Rating of Perceived Exertion) values for deep water exercise are typically 1 to 3 points higher. This phenomenon occurs due to several factors inherent in water-based exercises.

Firstly, exercising in water provides resistance and buoyancy, which can alter the perception of effort. While engaging in deep water activities, individuals may feel less strain on their joints and muscles due to the supportive nature of water. As a result, the perceived exertion may paradoxically increase. People might push themselves harder in the resistance of water, resulting in a higher RPE even if the objective intensity may be adjustable compared to land-based exercises.

Furthermore, the conditions for deep water exercise, such as the temperature of the water and the presence of drag, can also contribute to a heightened sense of effort. Since these factors can challenge the body differently than on land, the reported perceived exertion often tends to be higher in deep water settings. Hence, the typical RPE values recorded during such exercises are indeed elevated, reflecting the additional challenges that participants face, even while benefiting from the lower impact nature of the activity.
