Final Review Flashcards
Iso-metric
static (plank)
Hydrostatic Weighing and Bod Pod
Hydrostatic weighing is one of the most accurate methods
Percent body fat can be predicted from body density
Muscle weighs more than fat
The Bod Pod uses air instead of water
Circumference Measures
Waist circumference and waist to hip ratio can be used to measure abdominal obesity and predict health risk
Bioelectrical Impedance
This method incorporates a harmless electrical current passed from electrode to electrode
Electrical conduction favours the fat-free mass over fat tissue
Scanning Procedures
Very accurate method determining body fatness
Very expensive – requires sophisticated equipment
Procedures include:
CAT scan
MRI
Smart scales
Easy to use at home
Enhances awareness of body weight and composition
Important in behaviour modification strategies
Accurate for body weight, not so much for body composition
Nutrigenomics
the study of the interaction between nutrients and genes
Zinc
Critical for immune function and wound healing
Diabetes Mellitus
Condition causing difficulty in controlling glucose levels
Insoluble Fiber
Increases fecal bulk, prevents constipation
Soluble Fiber
Slows stomach emptying, reduces cholesterol absorption
Osteoporosis
Weight-bearing exercise helps build bone density, reduces risk of fractures
Carcinomas
Cancers arising from epithelial cells
