The perception of workload during deep water exercises is influenced largely by several factors, with lactic acid buildup being particularly notable in traditional land-based activities. However, in the context of deep water exercises versus land exercises, lactic acid buildup is less of a direct factor since water resistance and buoyancy engage different physical dynamics.

Deep water exercises utilize the properties of water to provide resistance and support, and typically do not lead to the same level of lactic acid accumulation as land exercises because they can be performed with less strain and over longer periods without the same level of metabolic fatigue accompanying high-intensity land workouts. This is crucial because perceiving a higher workload wouldn't primarily stem from lactic acid, making this choice less accurate in this specific comparison.

In deep water workouts, buoyancy plays a significant role. The body's buoyancy in water reduces impact and support, which can alter how effort is perceived compared to land-based exercises. Factors like excessive water temperature can lead to discomfort that might increase perceived exertion but are not inherently linked to water exercise dynamics. Lastly, low resistance levels would generally decrease perceived workload rather than increase it.

The correct understanding relates to how water's properties affect resistance and effort perception. In deep water exercises, individuals often feel a more significant workload
