00:00:00,240 --> 00:00:03,148
- Hi, I'm Captain Soto.
- I'm Staff Sargeant Pazmino,

2
00:00:03,148 --> 00:00:05,247
and we're with the Human Performance Branch.

3
00:00:05,247 --> 00:00:10,162
Our section, in collaboration with the
Army Research Institute of Environmental Medicine,

4
00:00:10,162 --> 00:00:12,346
is conducting a body composition study

5
00:00:12,346 --> 00:00:16,289
to ensure the Marine Corps policies 
and standards strike the right balance

6
00:00:16,289 --> 00:00:19,689
between health, performance,
fitness, and military appearance.

7
00:00:19,689 --> 00:00:23,977
- This study is one of the most
technologically advanced studies

8
00:00:23,977 --> 00:00:26,783
on the topic since the 1980s.

9
00:00:26,783 --> 00:00:30,271
The information gathered through
this study will help inform

10
00:00:30,271 --> 00:00:32,796
the future of HPB standards in the Marine Corps.

11
00:00:32,796 --> 00:00:35,372
Currently the study is underway

12
00:00:35,372 --> 00:00:37,433
at MCB Quantico, Camp Barrett,

13
00:00:37,433 --> 00:00:40,031
and will last until early 2022.

14
00:00:40,031 --> 00:00:43,686
Study volunteers will undergo
three body composition assessments

15
00:00:43,686 --> 00:00:45,267
via different methods

16
00:00:45,267 --> 00:00:49,073
such as the dual energy x-ray absorptiometry,

17
00:00:49,073 --> 00:00:51,199
3D body scan,

18
00:00:51,199 --> 00:00:54,366
bioelectrical impedance, and
one performance assessment

19
00:00:54,366 --> 00:00:56,621
conducted on a force plate.

20
00:00:56,621 --> 00:00:58,659
- DEXA is the industry gold standard

21
00:00:58,659 --> 00:01:01,556
that uses a three-compartment
model approach to quantify

22
00:01:01,556 --> 00:01:04,917
regional fat mass, lean mass,
and bone mineral density.

23
00:01:04,917 --> 00:01:07,913
Scans take approximately four to seven minutes

24
00:01:07,913 --> 00:01:10,951
and the Marines will receive
feedback from the scan.

25
00:01:10,951 --> 00:01:13,897
The 3D body scanner uses a 
two-compartment model approach

26
00:01:13,897 --> 00:01:16,731
to assess fat and lean mass.

27
00:01:16,731 --> 00:01:18,995
Scans collect two million data
points in eight seconds

28
00:01:18,995 --> 00:01:24,295
to process over 240 circumference-based 
body measurements in less than two minutes.

29
00:01:24,295 --> 00:01:28,390
Marines can then view a unique
digital 3D surface model of themselves

30
00:01:28,390 --> 00:01:30,490
and estimated body fat percentage.

31
00:01:30,490 --> 00:01:32,767
The bioelectrical impedance method

32
00:01:32,767 --> 00:01:34,995
uses an imperceptible electrical current

33
00:01:34,995 --> 00:01:38,271
that reacts differently in the
various compartments of the body.

34
00:01:38,271 --> 00:01:41,503
Lean tissues are good 
conductors of electricity,

35
00:01:41,503 --> 00:01:44,054
whereas fat and bone are not.

36
00:01:44,054 --> 00:01:47,498
BIA uses these differences to 
estimate lean mass and fat mass.

37
00:01:47,498 --> 00:01:51,503
- The countermovement jump is a
performance-based metric used in athletics.

38
00:01:51,503 --> 00:01:55,067
The force plate is designed to 
measure the forces and movement

39
00:01:55,067 --> 00:01:57,900
applied when a Marine jumps on it.

40
00:01:57,900 --> 00:02:01,432
