Hypertonic drinks are characterized by:

Hypertonic drinks are defined by their higher concentration of solutes—specifically sugar and electrolytes—compared to the body's fluids. When you consume a hypertonic drink, the concentration of particles in the drink exceeds that of the fluid found within your cells and bloodstream. This distinction is crucial because such drinks can draw water from cells into the digestive system, potentially leading to dehydration if not consumed in moderation.

This high concentration is particularly beneficial in situations where rapid replenishment of carbohydrates and electrolytes is required, such as during intense physical exertion or prolonged endurance sports. Understanding the role of hypertonic drinks can help athletes optimize their hydration and energy levels during performance.

In contrast, options discussing equal particle concentrations or lower concentrations misrepresent the fundamental properties of hypertonic solutions. Thus, the key characteristic defining hypertonic drinks lies in their abundance of sugar and electrolytes relative to the body's fluids.
