Study Notes
Body Composition and Health Status
- Body fat percentage (BF%) and Body Mass Index (BMI) are two methods used to estimate body composition and health status.
BMI and Body Fat Percentage
- BMI is calculated based on weight and height.
- BF% measures the actual amount of fat in the body.
- A strong correlation exists between BMI and BF%, meaning an increase in BMI corresponds to an increase in body fat percentage.
Weight Classifications and Body Fat Percentage
- BF% can be used to classify weight status regardless of weight and height.
- For men, the ideal body fat percentage ranges are:
- Athlete: 6-13%
- Fitness: 14-17%
- Acceptable: 18-24%
- Obesity: above 25%
Measuring Body Fat Percentage
- BF% can be measured using various methods, including:
- DXA (Dual-Energy X-ray Absorptiometry)
- BIA (Bioelectrical Impedance Analysis)
