Hydrotherapy can be used to strengthen injured areas by what mechanism?

Explanation:
Hydrotherapy strengthens injured areas by exercising against the resistance of water. When you move in water, its viscosity and drag push back, so muscles must generate greater force to perform movements. This resistance provides a progressive loading stimulus that promotes strengthening of the injured area. Buoyancy helps reduce the load on joints, allowing safer, controlled movement, but the key mechanism for strengthening is working against the water’s resistance. Choices suggesting no resistance or reduced resistance don’t produce the necessary loading for adaptation.
