What is Katch-McArdle formula?
The Katch-McArdle formula allows you to calculate your Basal Metabolic Rate, (BMR), which is the minimum amount of calories your body needs per day to keep functioning, assuming you were to do no exercise for that day. This equation differs from the Harris-Benedict equation because it takes into account lean body mass.
What is the Cunningham equation?
The Cunningham equation can be used to calculate your resting metabolic rate (RMR; the calories you burn while you’re at complete rest). The Cunningham equation has been found to yield acceptable estimates in muscular physique athletes [1]. The Cunningham equation is as follows: RMR = 22 * FFM + 500.
How do you calculate your RMR?
The Mifflin-St Jeor formula, created in the 1990s, provided an alternative and more valid estimate of RMR (3). The equations for males and females are: Men: (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) + 5. Women: (10 × weight in kg) + (6.25 × height in cm) – (5 × age in years) – 161.
Is Katch McArdle accurate?
The Katch–McArdle [38] equation was more accurate in the other two BMI groups, with 37% (25 to <30 kg/m2) and 53.4% (≥30 kg/m2). We have found discrepancies between most of the calculated equations and REEIC in women with normal weight, overweight, and ≥60 years.
How do you calculate Cunningham RMR?
The Cunningham5 equation [RMR = 500+22*{kg of free fat mass (FFM)}] gained popularity for use with able-bodied athletes after studies indicated that this equation provided the most accurate REE estimate when compared to indirect calorimetry able measurements of female and male endurance athletes.
How do you calculate RMR VO2?
How RMR is calculated: RMR per minute is calculated using the following equation: VO2/min × Thermal Equivalent. The thermal equivalent is a value derived from your averaged respiratory exchange ratio that expresses the kilocalories burned per liter of oxygen consumed.
How do you calculate BMR example?
BMR = 655 + (9.6 X weight in kilos) + (1.8 X height in cm) – (4.7 x age in years).
- Notes: 1 inch = 2.54 cm. 1 kilogram = 2.2 lbs.
- Example of BMR: You are 32 years old. You are 5 feet 4 inches tall (162.5 cm)
- Notes: 1 inch = 2.54 cm. 1 kilogram = 2.2 lbs.
- Example of BMR: You are 25 years old. You are 6 feet tall.
Is BMR and RMR the same?
Basal metabolic rate (BMR) and resting metabolic rate (RMR) both measure the amount of energy —in calories —that your body needs to stay alive and function properly. Many people use the two terms interchangeably, but they have slightly different meanings.
What is the dimensional formula of density?
The dimensional formula of density is given by, [M 1 L -3 T 0 ] Where, M = Mass. L = Length. T = Time.
What are the three ways to calculate density?
What are the three formulas for density? 1 To work out density: p = m / V 2 To work out the mass: m = p x V 3 To work out the volume: V = m / p
What is rdee formula for tdee?
Katch-McArdle Formula for RDEE can be a more precise representation of your BMR and therefore TDEE calculation when you know your lean body mass or body fat % accurately. Your Resting Daily Energy Expenditure (RDEE) is interchangeable with your Basal Metabolic Rate (BMR). They both are the amount of energy you burn while at rest daily.
How do you calculate density using P M/V?
The formula we showed you above (p = m/V) is the one we use to calculate density, but as there are three elements to that formula, it can be expressed in three different ways. Basically, you can rearrange the structure to work out different elements.
