Anthropometric Measurements And Body Composition Flashcards
What is in a two, three, and four compartment model of body composition
2 compartment
Lean body mass (muscle, bone, organs)
Fat mass
3 compartment
Lean body mass
Fat mass
Bone mineral density
4 compartment
Lean body mass
Fat mass
Bone mineral density
Water
List 3 reasons why one may measure weight or body composition
Address concerns about health
Determine contributions to performance
Best prepare an individual for a sport specific performance
Where is essential fat located
Heart, lungs, liver, spleen, kidneys, intestines, muscles, and central nervous system
Percent of essential body fat required for men and women
Men: 2-5%
Women: 10-13%
Bioelectrical Impedance Analysis pretest criteria
No food or drink for 2 hours
No caffeine use or heavy exercise for 4 hours
No alcohol consumption for 12 hours
Maintenance of test position for 5 minutes
What factors affects accuracy of skinfold thickness
Location (no twisting or bending)
Accuracy of equipment (Lange or Harpenden calipers are the most accurate)
Training of technician (measurements should be consistent within 1-3 mm range)
Estimates of BIA, skinfold thickness, and ADP percent body fat relative to Underwater Weighing (UWW)
BIA: 2.7-6.3%
Skinfold: 3.5%
ADP: 2-3%
Skinfold thickness sites
Triceps
Subscapular
Iliac crest (suprailiac)
Abdominal
Thigh
Midaxillary
Pectoral
What percentage of body weight loss will be seen in paraplegic and quadriplegic individuals
Paraplegia: 5-10%
Quadriplegia: 10-15%
Protein recommendations for fat loss
1.2-2.0 g/kg
Include adequate carbs to ensure that protein is primarily used for muscle building purposes, not energy
Rate of weight gain and weight loss for changing body composition
Gain: 0.25-0.5 kg/week
Loss: less than 1%/week
Recommended minimum time between body composition measurements
3 months
