In planning an athletic training facility, how is the number of whirlpools determined?

• A. Peak athletes divided by 3
• B. Peak athletes divided by 2
• C. A fixed unit per locker room
• D. Number of treatment tables

Answer: (A)

Sizing whirlpools is about aligning hydrotherapy capacity with how many athletes will need access at the same time. The idea is to keep rehab flow smooth and waiting reasonable without overbuilding. A practical rule used in planning is to provide one whirlpool for every three peak athletes. This ratio accounts for the fact that each session occupies the unit for a while and not everyone will need hydrotherapy simultaneously, so three athletes can cycle through during peak periods without creating bottlenecks.

Dividing peak athletes by two would overshoot the need, taking up more space and resources than necessary. A fixed unit per locker room ignores actual demand and usage patterns, potentially leaving either idle machinery or long waits. The number of treatment tables relates to the treatment area, not hydrotherapy capacity, so it doesn’t directly determine how many whirlpools are required.

Thus, planning the number of whirlpools based on peak demand using the 1:3 ratio best balances efficiency, safety, and space.
