In nutrition, there are many factors that influence an individual’s health and body weight, such as
heredity, food selection, eating behaviors, and physical activity.
Scale weight is not always a
good indicator of body fat, lean mass, body water or overall health (1).
experience will give students the opportunity to conduct physical assessments by evaluating
body weight and body composition.
To determine body weight and body composition,
techniques such as bioelectrical impedance analysis (BIA), body mass index (BMI), waist
circumference, wrist circumference for determining frame size, and a scale will be utilized.
Students will also evaluate their own risk for cardiovascular disease and assess cardiovascular
health in volunteers by measuring heart rate, filling out a heart disease risk score form, and
estimating oxygen consumption and energy expenditure through a technique known as the
Queens College Three-Minute Step Test.
Your body is made up of the six essential nutrients: water, fat, protein, carbohydrates and various
vitamins and minerals.
Many factors can influence an individual’s health and body weight:
heredity, eating behaviors, food selection, and amount of daily exercise.
previously, weight is not a good indicator of bodily health and balance.
For any individual of a
given height, there is no single best weight, but a range of healthy weights best determined by
one’s body composition.
For directly assessing an individual’s body composition, it is common
for bioelectric impedance analysis (BIA) to be performed.
Additionally, wrist circumference to
determine frame size and calculating one’s body mass index (BMI) are two commonly used
methods for indirectly assessing body composition.
Combinations of these direct and indirect
techniques can lead to an overall understanding of body composition allowing for prescriptions
of exercise and nutrition to be levied for any desired positive and healthy changes.
It is typically most useful to consider the body’s composition in its simplest terms of fat mass,
lean mass, and water mass.
This concept can be taken down further by estimating percentages of
