    Study Notes

    Anthropometric Methods and Skinfold Measurement

    • Skinfold measurement is used to estimate subcutaneous fat and total body fat based on specific assumptions.
    • Population-specific and generalized equations are used for estimating body fat based on skinfold measurements.
    • The accuracy of skinfold measurements is affected by technician skill, type of caliper used, and client factors such as hydration level and compressibility of adipose tissue.
    • Caliper calibration and using the same type of caliper for monitoring changes in skinfold thickness are important to minimize measurement error.
    • Anthropometric methods can be used to estimate body composition, including total and regional body composition, and to assess body size, proportion, and segment sizes.
    • Circumference and skeletal diameter measurements are used to estimate fat and muscle mass, classify frame size, and assess disease risk.
    • Anthropometric indices such as BMI, waist circumference, waist-to-hip ratio, waist-to-height ratio, and sagittal abdominal diameter are used to assess regional fat distribution and disease risk.
    • BMI is calculated as the ratio of body weight to height squared and is used to classify individuals as obese, overweight, or underweight, and to identify those at risk for obesity-related diseases.
