Table 1 Body fluid loss during experiment

From: A comparison of hydration effect on body fluid and temperature regulation between Malaysian and Japanese males exercising at mild dehydration in humid heat

  Body weight loss, %   Total sweat loss, g · kg-1   Urine weight, g · kg-1   Urine specific gravity   ΔUrine specific gravity
Japanese non-hydrated -1.77 (0.11) 15.3 (1.1) 1.8 (0.4) 1.022 (0.001) 0.005 (0.002)
Japanese hydrated -1.04 (0.14) † 17.2 (1.3) † 4.6 (1.1) † 1.012 (0.002) † -0.009 (0.004)†
Malaysian non-hydrated -1.61 (0.09) 13.6 (0.8) 2.1 (0.4) 1.016 (0.002) 0.002 (0.002)
Malaysian hydrated -0.66 (0.08) *† 14.4 (0.8) † 3.8 (0.7) 1.011 (0.003) -0.006 (0.003)†
  1. Values are the mean (SE) for 10 Japanese and 10 Malaysians in the non-hydrated and hydrated conditions. ΔUrine specific gravity is the change from pre- to post-experiment. *Significant difference between Japanese and Malaysian participants in the hydrated or non-hydrated condition. †Significant difference between the hydrated and non-hydrated condition in Japanese or Malaysians.
