Body composition refers to the distribution of fat and fat-free mass in the body. It is an important consideration in sports, as different sport disciplines favor different body types. There are several methods to measure body composition, including skinfold calipers, hydrodensitometry, DEXA, BIA, and Bod Pod. These methods vary in accuracy and complexity, from the simple skinfold calipers to the more sophisticated DEXA and Bod Pod tests. Maintaining the proper body composition and body fat levels is important for health and athletic performance.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
2. BODY COMPOSITION
Body Composition is
the distribution of fat
and fat free mass in the
body.
Fat is the total weight of
fat mass (in kg , lb) in
the body.
Fat Free Mass is
comprised of muscle,
bone, tissue, water, and
all other fat free mass in
the body.
3. WHY BODY COMPOSITION IN SPORTS?
It is considered to be an important physical development especially in
sports, where there is an advantage of being tall (e.g. basketball) or
small (Libero, weightlifting), heavy (sumo wrestling, Shot Put) or light
(gymnastics), etc.
A tall runner’s longer limbs will enable longer step length (Winter,
1990).
Height, Body Mass and BMI seems to be important anthropometric
parameters for sprinters (Niels Uth, 2005)
Indians have shorter height, lower BMI but higher body fat content.
Waist circumference is lower but the chest & abdominal fat is higher in
comparing with Caucasians (Misra et al, 2004)
Excess fat among Indians generate more inflammatory molecules which
significantly contributes to heart diseases & diabetes (Joglekar et al,
2003)
4. BODY COMPOSITION MODEL
2 compartment system;
Fat
Fat free Mass
Assessment methods using this
model:
Skinfold thickness
Hydrodensitometry
Bioelectric impedance
5. CHEMICAL AND ANATOMICAL MODEL
Anatomical Model
4- compartmental (water,
protein, fat , minerals)
Dual emmision x-ray
absorptiometry (DEXA)
Computed tomography (CT,
CAT)
Chemical Model
2- compartmental (Fat and
Fat free mass)
3- compartmental (Fat,
Bones and Mineral)
6. FIVE COMPARTMENT MODEL
Fat,
Bones Tissue,
Extracellular water,
Intracellular,
Metabolic Tissue
Example: Tanita Body
Composition Analyser
7. ATHLETIC BODY TYPE
Athletic or Muscular Body
Type who has normal or low
body fat even though they
are overweight according to
the standard chart.
Example: Body Builder
8. LINEAR BODY TYPE
Lean, thin or Linear Body type
with low amount of fat free
mass who can be underweight
according to the weight chart
and extremely low in body fat
yet physically very healthy.
Example: Endurance runners
9. AVERAGE HEALTHY WEIGHT BODY TYPE
People of average weight and
average body fat
Example: Active People
10. OVERWEIGHT AND OBESE BODY TYPES
Big, heavy and soft body types
who are overweight and obese
with large amount of fat mass
and body weight.
Example: Inactive elderly
11. OBESE NOT OVERWEIGHT BODY TYPES
People who have too
much fat mass and are
obese but not overweight
due to inactive and
sedentary life style.
Example: Elder people
15. MEASURING OF BODY COMPOSITION
1) Skinfold caliper
Most commonly used in the
field of sports for testing body
fat.
Measures double thickness of
skin and subcutaneous fat
The common sites for
measuring skinfold are triceps,
biceps, subscapular, illiac crest,
abdominal, thigh, calf
16. HYDRODENSIOMETRY
2) This method is also quite
accurate and considered a
gold standard method.
Two compartment model
Archimedes principles:
volume of submerged object =
volume of water displaced
weight in air - weight underwater
= weight of water displaced
Wt of water displaced = vol of
body
Density = Body weight/Body
volume
% BF = (495/BD)- 450
17. DEXA
(DUAL ENERGY X-RAY ABSORPTIOMETRY)
3 body components (fat,
muscle, bone)
It allows fat distribution
throughout the entire body to
be read in a single scan.
18. BIA
(BIOELECTRICAL IMPEDANCE ANALYSIS)
It uses a very small electrical
signal to measure body
impedance.
Fat causes impedance or
resistance to the signal.
The entire procedure takes less
than one minute.
No need for a trained
technician to operate the
equipment
BIA produces very accurate
results.
19. BOD POD
It uses the whole-body
densitometry to determine body
composition.
It is similar in principle to the
underwater weighing
Body density can then be
calculated
Density = Mass/Volume
20. CONCLUSION
An athlete can be overweight according to their height – weight table
but yet have very little body fat (Welham and Behnke, 1942).
Being overweight is usually not a problem, but being over-fat typically
has negative impact on the athletic performance.
The Health/Fitness practitioners need to educate the general
population about the desirable level of fatness.
Every technique has there advantages and disadvantages. A
combination of these methods may reduce the likelihood of
misdiagnosis of Body Composition.
