Table 3 Urinary specific gravity index for hydration status

From: The role of age in the physiological adaptations and psychological responses in bikini-physique competitor contest preparation: a case series

Index for Hydration Status
Condition USG Value
Well-hydrated < 1.010
Minimal dehydration < 1.010–1.020
Significant dehydration 1.021–1.030
Serious dehydration > 1.030
  1. Urine Specific Gravity (USG); ≤1.020 is an indication of euhydration status [38]
