An independent total body water measurement, paired with plasma-volume measurements, would address that distinction. Suppose measurements before exercise, immediately afterward and after recovery showed stable total body water while plasma volume fell and then recovered: that would support temporary redistribution, within measurement uncertainty. Establishing the specific interstitial increase in my example would require additional compartment evidence; those two measurements alone wouldn't locate the displaced water.

Suppose plasma volume falls immediately after exercise while interstitial water rises equally and total body water stays constant, with both compartments returning to baseline during recovery.

You're right that timing doesn't identify adaptation if groups received different exercise doses. The title alone doesn't show whether repetitions, load, work, or rest were recorded, so those variables need checking alongside the sampling schedule before interpreting phenotype differences.
