Cheat Sheet
- Understanding Fat vs. Lean Mass -
Distinguishing fat mass from lean (muscle, bone, water) mass is central to any body composition quiz and reveals how energy stores relate to performance. Fat-free mass correlates with basal metabolic rate, while excess adiposity can increase disease risk (American College of Sports Medicine).
- How to Calculate Body Composition -
Common laboratory methods include DEXA, hydrostatic weighing, and BIA, while field tests use skinfold calipers or circumference measures to calculate body composition. For example, the Siri equation estimates body fat percentage: BF% = (495/Body Density) - 450 (Journal of Applied Physiology).
- Estimating Daily Caloric Needs -
You can use the Mifflin-St Jeor equation (BMR = 10×kg + 6.25×cm - 5×years + s) and multiply by an activity factor to set your daily target; interestingly, the average adult eats about 4000 calories a day according to NHANES data. Adjusting calories based on goals - deficit, maintenance, or surplus - helps you control body composition over time (National Institutes of Health).
- Setting Your Intensity Level -
To set your intensity level you need to calculate your target heart rate using the Karvonen method: Target HR = [(HRmax - RHR) × Intensity%] + RHR. This personalized approach ensures workouts stay in aerobic or anaerobic zones to maximize fat loss or muscle gain (American Heart Association).
- Strategies to Control Body Composition -
Effective control of body composition blends resistance training, high-intensity interval training, and balanced macronutrients; remember the FITT mnemonic - Frequency, Intensity, Time, Type - to design workouts. Consistent tracking and periodic re-assessment through a body composition quiz keep you accountable and confident in your progress.
