INTERPRETING
MEASUREMENTS
In basic terms, SOSM values
increase as dehydration
increases, and they decrease as
hydration status improves. Most
people will exhibit a gradual
increase in SOSM as they
exercise. This relative change
in SOSM is reected in the
status scale bar that appears
in the MX3 App immediately
after a measurement is taken.
While comparison of SOSM
measurements with population
averages can provide an
estimate of hydration status,
every individual’s SOSM range
and hydration response is
unique. To provide the most
accurate hydration analysis,
SOSM measurements should be
compared to a personal baseline
measurement taken under
optimal hydration conditions.
By making comparisons to
this individual, users can learn
more about their personalized
hydration range. A small
proportion of people will lose
an unusually large amount
of salt for a given amount of
water loss when exercising.
For these individuals SOSM
may not change signicantly,
indicating that water has not
been selectively lost. Isotonic
solutions may assist recovery in
these instances.
