3 hours Post Dehydrating Exercise* 291.2 ± 6.6 290.0 (285.0 - 310.0) 289.6 ± 5.5 288.0 (283.0 - 304.0) 291.8 ± 5.7 289.0 (286.0 - 306.0) 290.3 ± 5.1 289.5 (284.0 - 302.0)
  1. Data are mean ± SD (top row); median and (range) provided in bottom row
  2. *Coconut water from concentrate greater than bottled water (p = 0.049); when expressed as change from Pre Dehydrating Exercise at 3 hours Post Dehydrating Exercise. No other differences noted (p > 0.05).
