Hydration status of 2017 Malaysian Agong Cup Rugby Referees / Muhammad Hafizuddeen Bahari

The purpose of this study was to determine the hydration status of 2017 Malaysian
Agong Cup rugby referees based on parameters set which are bodyweight changes,
urine specific gravity (uSa), urine pH value (uPH), and urine colour pre and post match
as well as the sweat rates data post-match. There were six (N=6) referees
partaken in this study. Bodyweight changes, usa, uPH and urine colour were
measured before and after each match took place whereas sweat rates was calculated
after each match. (Mean ± SD) of pre-match bodyweight changes, usa, uPH and urine
colour were (71.35 kg ± 3.95), (1.015 ± .00), (5.67 ± 1.03) and (6 ± 1.84) respectively.
(Mean ± SD) of post-match bodyweight changes, usa, uPH, urine colour and sweat
rates were (69.65kg ± 3.63), (1.016 ± .01), (4.83 ± .41), (6 ± 2.79) and (1.86 L ± .90)
respectively. Results from paired sample tests of bodyweight changes and usa data
showed significant differences in between pre and post-match whereas uPH and urine
colour data showed no significant differences in between pre and post-match. To
conclude, from mean data of bodyweight changes showed 2.38% of decrement in
bodyweight changes, whereas for usa, uPH and urine colour mean data showed that
the referees started the match with minimal dehydration based on the scale of each
parameters and the sweat rates data showed that referees should at least replenish
1.86L of fluid after match to level out the fluid loss during the match.
