Study Notes

  • Body composition refers to the proportions of fat and fat-free mass within the body, typically expressed as a percentage of body fat.
  • Overweight indicates a weight that exceeds the recommended health guidelines.
  • Obesity is characterized by an excessive fat percentage, generally above 25% in men and 35% in women.
  • Essential fat is crucial for normal physiological functions and health.
  • Storage fat comprises excess fat reserves beyond what is essential for health.

Types of Fat and Tissue

  • Adipose tissue is the type of connective tissue responsible for fat storage in the body.
  • Visceral fat is the fat located in the abdominal cavity, surrounding internal organs, which can pose health risks.
  • Subcutaneous fat is found just beneath the skin, playing a role in body insulation and protection.

Fat Distribution Patterns

  • The android pattern of fat distribution is prevalent in men and characterized by fat accumulation around the abdomen, often linked to higher health risks.
  • The gynoid pattern is more common in women, with fat concentrated in the hips and thighs.

Health Impacts and Measures

  • Creeping obesity refers to gradual weight gain and increased body fat percentage over time, often unnoticed.
  • Diabetes is a metabolic disorder indicated by high blood sugar levels, raising the risk of various health complications.
  • Body Mass Index (BMI) evaluates a person's body weight relative to height, offering insights into health status linked to body fat percentage.

Assessment Techniques

  • The skinfold test estimates body composition by measuring subcutaneous fat at specific body sites using calipers.
  • The waist-to-hip ratio helps assess obesity patterns by comparing waist and hip measurements.
  • Dual Energy X-ray absorptiometry (DXA) is a precise method for body composition assessment, using low radiation levels deemed a gold standard in clinical environments.
  • Hydrostatic weighing measures body composition based on weight differences in and out of water.
  • Air displacement measures body composition by evaluating the amount of air displaced in a closed chamber.
  • Bioelectrical Impedence Analysis (BIA) determines body composition through the flow of a low-level electrical current through body tissues.
