Body Composition Flashcards
1
Q
What is FFM
A
Fat Free Mass
2
Q
What does FFM consist of?
A
- Muscle
- Bone
- Water
- Organ tissue
3
Q
What is total body fat?
A
- Essential fat
- Storage fat
4
Q
What is the essential fat used for
A
- Major organs
- Muscles
- Central nervous system
5
Q
What are the percentages for essential fat levels in males and females?
A
Male = 3-5%
Female= 8-12%
6
Q
Where is nonessential fat stored?
A
It is stored as adipose tissue near the body’s surface.
7
Q
What is the reason for assessing body composition?
A
- To help assess health risks and determine needed behavior changes for optimal health
- To help athletes determine the best body composition for performance in their respective sport
8
Q
What are the problems caused by excessive body fat?
A
- Cardiovascular disease
- Hypertension
- Type 2 diabetes
- Cancer
9
Q
What are the methods of assessing body composition?
A
- height, weight, and BMI
- Hip-waist ratio
- Hydrostatic weighing
- Skinfold tests
- Air displacement plethysmography
- Biological impedance analysis (BIA)
- Dexa scan
10
Q
How does the skinfold technique work?
A
- Multiple sites are meshed around the body and body fat % can be calculated from the sum of all these sites.
11
Q
Where are the skinfold measurement sites?
A
- Biceps
- Triceps
- Subscapular
- Illiac Crest
- Supraspinal
- Abdominal
- Front Thigh
- Medial Calf
12
Q
What are the pros of hydrostatic Weighing?
A
- Most commonly used method for measuring body fat percentage.
- Uses whole-body density to calculate body composition. (fat is more buoyant than lean tissue)
13
Q
What are the cons of hydrostatic weighing?
A
- Time-consuming
- Not feasible for large groups of athletes
