Schofield Equation for 13 Year Olds:
| From: | To: |
The Schofield equation is a widely used formula for estimating Basal Metabolic Rate (BMR) - the number of calories your body needs at rest to maintain basic physiological functions. This specific equation is calibrated for 13-year-old individuals.
The calculator uses the Schofield equation for 13 year olds:
Where:
Explanation: The equation calculates the minimum energy expenditure required to sustain vital body functions while at complete rest.
Details: Understanding BMR is essential for determining daily caloric needs, creating appropriate nutrition plans, managing weight, and supporting healthy growth and development during adolescence.
Tips: Enter accurate weight in kilograms and height in centimeters. For best results, use measurements taken in the morning before eating or drinking.
Q1: Why is this equation specific for 13 year olds?
A: Metabolic rates vary significantly by age. The Schofield equation uses age-specific coefficients to account for developmental differences in metabolism.
Q2: What is a typical BMR range for 13 year olds?
A: BMR varies based on size, gender, and body composition, but typically ranges from 1200-1800 kcal/day for 13 year olds.
Q3: How does BMR differ from total daily energy expenditure?
A: BMR represents only basal metabolic needs. Total energy expenditure includes additional calories burned through physical activity and food digestion.
Q4: Does this equation account for gender differences?
A: This specific equation is generalized for 13 year olds. More precise calculations may use gender-specific equations when available.
Q5: How often should BMR be recalculated?
A: BMR should be recalculated every 3-6 months during adolescence or whenever there are significant changes in weight or height.
