Study Notes
Body Volume Measurement
- An egg-shaped chamber is used to estimate body volume through air pressure changes.
Skinfold Measurements
- Body fat percentage is estimated by pinching skin at specific locations and measuring thickness with calipers.
- Formula for Waist-Hip Ratio (WHR):
WHR = waist circumference / hip circumference.
Body Mass Index (BMI)
- BMI serves as an indicator of weight in relation to height.
Factors Affecting Basal Metabolic Rate (BMR)
- Stress hormones increase BMR.
- Environmental adjustments to temperature (heat or cold) can raise BMR.
- Fasting or starvation reduces BMR.
- Malnutrition also lowers BMR.
Calculating Estimated Energy Requirement (EER)
- EER formula for adult males:
EER = 662 − [9.53 x age (y)] + PA x [15.91 x wt (kg) + 5.39 x ht (m)] - EER formula for adult females:
EER = 354 − [6.91 x age (y)] + PA x [9.36 x wt (kg) + 726 x ht (m)]
Physical Activity Levels and PA Factors
- Sedentary: Men 1.0, Women 1.0
- Low active: Men 1.11, Women 1.12
- Active: Men 1.25, Women 1.27
- Very active: Men 1.48, Women 1.45
Example Calculation
- To calculate EER for an active, 30-year-old man who is 1.8 m tall.
