In many studies the ground reaction force(GRF) and joint moments are compared between subjects; in addition, free moments are becoming a more commonly investigated variable. Most authors will normalize the data to remove the differences seen due to the subjects' physical characteristics such as height and weight. It is most common for researchers to linearly normalize using simple division, the GRF by Body Weight( BW), joint moments by Body weight height(BWH), and free moments by BWH, as it is generally believed that heavier subjects will create larger GRF and joint moments when moving at the same speed as lighter subjects. This allows us to compare more meaningful data, as the effects of the height and weight of the subjects are theoretically neutralized by the normalization procedure

The Body Mass Index (BMI) is a value calculated based on the
weight and the height of an individual. In a small European city, a
survey was conducted one year ago to review the BMI of the
citizens. In the sample

with 200 citizens, the mean BMI was 23.3 kg/m and standard
deviation was 1.5 kg/m . It is reasonable to
assume the BMI distribution is a normal distribution.

Metabolic rate, the rate at which the body consumes energy, is
important in studies of weight gain, dieting, and exercise. The
provided table gives data on the lean body mass and resting
metabolic rate for 12 women and 7 men who are subjects in a study
of dieting. Lean body mass, given in kilograms, is a person’s
weight leaving out all fat. Metabolic rate is measured in
kilocalories (Cal) burned per 24 hours, the same calories used to
describe the...

What is the weight of the body?
A spring balance has a scale that reads from 0 to 50 kg. The length of the scale is 20 cm. A body suspended from this balance, when displaced and released, oscillates with a period of 0.6 s. What is the weight of the body?

Total blood volume (in ml) per body weight (in kg) is important
in medical research. For healthy adults, the red blood cell volume
mean is about μ = 28 ml/kg.† Red blood cell volume that is
too low or too high can indicate a medical problem. Suppose that
Roger has had seven blood tests, and the red blood cell volumes
were as follows.
