was similar in all trials. There were no difference at any
time in serum Na+ and Cl–, serum osmolality, and net fluid
balance between the three trials. Urine osmolality
decreased after 1 h during the rehydration period and it
was lowest in the PW tr i al . Plasma glucose
concentrations were significantly higher compared with
PW ingestion when CW and CEB were ingested during
the rehydration period. CW was significantly sweeter,
caused less nausea, fullness and no stomach upset and
was also easier to consume in a larger amount compared
with CEB and PW ingestion. In conclusion, ingestion of
fresh young coconut water, a natural refreshing beverage,
could be used for whole body rehydration after exercise.
