Introduction to Fitness and Health

These flashcards cover key concepts related to obesity, body composition assessment methods, and health risk classification based on BMI.

BMI

Body Mass Index, calculated as weight (kg) / height (m²), a common measure of obesity.

Mortality Risk

The relationship between body mass index (BMI) and the likelihood of death; very low and very high BMI increases risk.

Health Risk Classification

Categorization of health risk based on BMI for adults, ranging from underweight to obesity class III.

Body Composition

The body's composition includes fat mass and fat-free mass, which encompasses bones, organs, muscles, and connective tissues.

Densitometry

A method used to measure body fat based on the density of the body, utilizing Archimedes’ Principle.

Bioelectrical Impedance Analysis (BIA)

A method that estimates body composition by measuring resistance to electrical flow, affected by hydration status.

Skinfold Measures

A technique to assess body fat by measuring the thickness of skin and fat at specific sites.

Anthropometry

The study and measurement of the human body, often used in the assessment of body composition.

Computed Tomography (CT)

A medical imaging technique that enhances the visualization of internal structures through cross-sectional images.

Dual Energy X-ray Absorptiometry (DEXA)

A technique used to measure bone mineral density and body composition, providing more detailed information.
