Study Notes

BMI Formulas

Formula for Body Mass Index (BMI): Weight in kilograms divided by height in meters squared or weight in pounds divided by height in square inches multiplied by 703.
BMI is a commonly used metric for assessing body weight relative to height.

Waist to Hip Ratio

Calculated by dividing waist circumference by hip circumference.
This ratio helps evaluate fat distribution and potential health risks associated with obesity.

Fat Body Mass

Computed as total body weight multiplied by body fat percentage.
Indicates the weight of fat tissue in the body.

Lean Body Mass

Determined by subtracting fat mass from total body weight.
Represents the weight of all body components except fat, such as muscles, bones, and organs.

Exercise Intensities

Moderate exercise intensity ranges between 40 to 60 percent of maximum effort.
Vigorous exercise intensity falls between 60 to 85 percent of maximum effort.

Goal Weight Calculation

Starts with calculating lean mass and determining the targeted weight based on desired lean percentage.
To find weight loss: subtract the new target weight from the old weight.

Karvonen Method

Target Heart Rate is calculated using the formula: ((max heart rate - resting heart rate) × %Intensity) + resting heart rate.
This method personalizes heart rate training zones for individuals based on their fitness levels.
