Adjusted Body Weight Calculator:
Enter the values of Ideal Body Weight, IBW(kg) and Actual Weight, AW(kg) to determine the value of Adjusted Body Weight, ABW(kg).
Adjusted Body Weight Formula:
The concept of Adjusted Body Weight (ABW) in physics primarily relates to how weight distribution and body composition affect the overall mass and mechanics of the human body.
Though ABW is mostly a medical and nutritional concept, its application can be analyzed through the lens of physics when considering forces, mass distribution, and the centre of gravity.
As the ABW changes, the body’s centre of gravity may shift. A higher ABW may indicate more mass in specific areas, altering the centre of gravity and affecting how the body maintains balance and posture.
The work required to move a body with a higher ABW increases due to the additional mass. This means that more energy is needed to perform the same physical activities compared to a body with an IBW.
The Adjusted Body Weight, ABW(kg) in kilograms is calculated by adding the Ideal Body Weight, IBW(kg) in kilograms to 0.4 of the difference between the Actual Weight, AW(kg) in kilograms and the Ideal Body Weight, IBW(kg).
Adjusted Body Weight, ABW(kg) = IBW(kg) + 0.4 * (AW(kg) – IBW(kg))
ABW(kg) = adjusted body weight in kilograms, kg.
IBW(kg) = ideal body weight in kilograms, kg.
AW(kg) = actual weight in kilograms, kg.
Adjusted Body Weight Calculation:
- A patient has an Ideal Body Weight (IBW) of 60 kg and an Actual Body Weight (AW) of 90 kg. Calculate the Adjusted Body Weight (ABW).
Given: IBW(kg) = 60kg, AW(kg) = 90kg.
Adjusted Body Weight, ABW(kg) = IBW(kg) + 0.4 * (AW(kg) – IBW(kg))
ABW(kg) = 60 + 0.4 * (90 – 60)
ABW(kg) = 60 + 12
ABW(kg) = 72kg.
- A patient’s Ideal Body Weight (IBW) is 55 kg, and their Adjusted Body Weight (ABW) is calculated to be 70 kg. Determine the patient’s Actual Body Weight (AW).
Given: IBW(kg) = 60kg, AW(kg) = 90kg.
Adjusted Body Weight, ABW(kg) = IBW(kg) + 0.4 * (AW(kg) – IBW(kg))
AW(kg) = (ABW(kg) – IBW(kg) / 0.4) + IBW(kg)
AW(kg) = (70 – 55 / 0.4) + 55
AW(kg) = 37.5 + 55
AW(kg) = 92.5kg.
