InBody Technology

Question 1

4 features of InBody Technology

Answer 1

1. Direct segmental BIA (5 cylinder model)
2. Multi frequency
3. 8 points tactile electrode
4. No use of empirical estimations

Question 2

DSM-BIA

Answer 2

Trunk has low length, higher cross sectional area compared to arms but lowest oms (20-30).
However, trunk has 50% of our lean body mass so it has the largest amount of water and muscle.

Must be separately measured or we over/underestimate whole body muscle mass according to body type

Question 3

Importance of trunk

Answer 3

A 1-2 om difference in trunk impedance can create a great change in LBM

Question 4

What direction does current flow

Answer 4

Palm, trunk, to leg

Left arm measurement = currents flow left arm, trunk, to left leg

Question 5

Voltage check

Answer 5

Voltage goes from left thumb to right thumb

Question 6

Trunk measurement

Answer 6

Currents flow from Right hand to Right front sole

Voltage from left thumb to left rear sole

Question 7

How many frequencies does InBody use

Answer 7

6 frequencies from 1kHz to 1000kHz

Question 8

Multi frequency

Answer 8

Multi frequency allows to distinguish between ICW and ECW and accurately measure TBW

Question 9

8 point tactile electrode with thumb electrode

Answer 9

99 % reproducibility with voltage measurements always starting at the same point of wrist and ankles

Question 10

Empirical estimations

Answer 10

Variables based on common knowledge accumulated throughout time

I.e

• men have more muscle than woman
• seniors have more fat mass than younger people
• as we age limbs get thinner and trunk gets wider
