Maltron Body Composition Analysers have been developed using the
finest and most
advanced circuitry of its kind, offering you the world’s
first low cost British manufactured, high
specification, hand-held system
for the measurement of whole body composition.
The Maltron Analysers are rapid, non-invasive instruments for field and clinical settings
offering unique features never before available in
instruments of this kind. Maltron Analysers
deploy the scientific method of four electrodes (tetra-polar) which are applied to the
hand, wrist, foot and ankle. A low-level electrical current is passed through the body
and the impedance
(z)
or opposition to the flow of current is measured using the Maltron
Body Composition Analyser.
The impedance value that is a function of Resistance when measured with
Maltron Body Composition Analyser is then
applied to pre-stored scientific
equations for different age groups, ethnicity, gender and physical
activity levels.
Fat Free body contains 73–75% water and therefore Fat Free Mass (FFM) can
be predicted from Total Body Water (TBW).
The larger Fat Free Mass and
Total Body Water the less Resistance to current flow, compared to those
with a smaller
Fat Free Mass.
Total Body Water (TBW) of an individual can be estimated from impedance
measurement obtained by Maltron Body
Composition Analyser as the
electrolytes in body water are much better conductors of electrical current
than Fat Mass (FM).
Fat Mass has relatively low water and is therefore a
poor conductor of electrical current with less Resistance (R).

lying down method
of measurement provides equilibrium of water
compartments and indication of current flow |
The current flows more easily when Total Body Water is larger and
the opposite (Resistance) occurs when an individual has large Body
Fat given that adipose tissue is a poor conductor of electrical
current
as it contains very little water. Impedance value measured
by the
Maltron Body Composition Analyser is an indicator of the
changes
taking place in one’s body composition. The Resistance value
is of
particular importance to professionals researching in Sports
Medicine,
Clinicians and Medics. |
The changes in impedance value can help estimate one’s nutritional status,
consecutive measurement over a period may
show fluid loss provided no
significant changes in body weight. Under normal hydration if impedance
values are consecutively
low this indicates a possible increase in lean
mass. On the other hand if the values are higher under normal hydration,
this is
an indicator of larger Fat Mass.
Maltron Body Composition Analyser has the potential to assess regional
body composition, particularly the soft tissue
composition of the trunk.
Additionally with the new Maltron Multi-frequency Bioelectrical Impedance
Analyser, it is possible to
estimate Extracellular water and Intracellular
water compartments along with TBW. This enhances the clinical application
of BIA
to assess changes and shifts in the Intracellular and Extracellular
water compartments associated with certain diseases. |
