How do you measure body composition? Body fat testing can be done in a number of different ways. To calculate body fat, the equation is as follows: For men: 0. Triceps: A vertical fold on the backside of the upper portion of the arm. The arm must be relaxed and held easily on the side of the body.
The test must be taken halfway between the shoulder and the elbow. Subscapular: A degree fold of between one and two centimetres between the inferior angles of the subscapular. Illiac crest: A degree angle fold taken just above the iliac crest media to the axillary line. Bioelectric impedance measurements An electrical current is delivered through the body in order to measure fat.
Underwater weighing This method determines the portion of fat to lean tissue. Circumference measurements Circumference measurements can be an additional way of feedback for clients wanting to change their body composition.
Areas that are usually measured are: Chest: Across the nipple line Waist: The narrowest part of the waist just above the hip bones Hips: Feet must be together and the tape must be placed at the widest part of the buttocks Thigh: 25cm on top of the knee Calves: The largest circumference between the ankle and the knee Biceps: Arms must be straight with the palms facing forwards and the largest part of the bicep must be measured Contact Trifocus Fitness Academy If you want to discover more about helping people to reduce the amount of fat in their bodies then you need to do our Personal Training Diploma.
Body Composition Essentials The assessment of body composition involves using the most appropriate, and accessible, method possible to estimate a persons body composition an actual assessment of body composition would be by cadaver analysis. The terms fat-free mass and lean body mass are often incorrectly used interchangeably.
Practical Uses of Body Composition Assessments for Personal Trainers Heyward and Stolarczyk suggest the following ways the personal trainer can use body composition measures: 1. To identify the clients health risk associated with excessively low or high levels of total fat 2.
To identify the clients health risk associated with excessive accumulation of intra-abdominal fat 3. To promote the clients understanding of health risks associated with too little or too much body fat 4. To assess the effectiveness of nutrition and exercise interventions in altering body composition 5.
To estimate ideal body weight of clients and athletes 6. To formulate dietary recommendations and exercise prescriptions 7. To monitor growth, development, maturation, and age-related changes in body composition.
An improperly trained technician will introduce considerable measurement error. Additionally, it is important to follow standardized guidelines and testing procedures when using the SKF technique.
The personal trainer is referred to the Anthropometric Standardization Reference Manual Harrison et al. However, with the popularly used generalized equations by Jackson and Pollock and Jackson, Pollock and Ward , follow the guidelines presented in Table 2.
For consistency with your clients measurements, make sure you monitor your their changes using the same calipers. Most SKF measurements use two to three SKFs to predict body density Db , from which body fat can be derived using the appropriate equation.
However, for higher precision, SKF prediction equations that take into account a clients age, gender, ethnicity, and physical activity level are recommended.
Heyward and Stolarczyk provide specific SKF equations based on the factors cited above. Your clients will have variation in skin thickness, compressibility of adipose tissue, and hydration level, which will affect the SKF measurement.
Keep a record of these observations for follow-up assessements. Exercise also increases the extracellular water accumulation in the subcutaneous tissue and thus will increase skinfold thickness.
Therefore, SKFs should not be measured immediately after exercise, especially in warmer environments. Skinfold Measurement Procedures. The following procedures will increase your reliability and precision when doing SKF measurements Harrison et al.
Take all SKF measurements on the right side of the body. Carefully identify, measure and mark the SKF site. Grasp the SKF firmly between the thumb and index finger of your hand. The fold is lifted 1 cm above the site to be measured. Lift the fold by placing the thumb and index finger 8 cm ~3 inches apart on a line that is perpendicular to the long axis of the skinfold.
The long axis is parallel to the natural cleavage lines of the skin. For individuals with extremely large skinfolds, the thumb and finger will need to be separated more than 8 cm in order to lift the fold. Keep the fold elevated while the measurement is taken.
Place the jaws of the caliper perpendicular to the fold, approximately 1 cm below the thumb and index finger, and release the jaw pressure slowly. Take the SKF measurement 4 seconds after the pressure is released.
Open the jaws of the caliper to remove it from the site. Close the jaws slowly to prevent damage or loss of calibration. Take a minimum of two measurements at each site. Take SKF measurements in a rotational order rather than consecutive readings at each site. Take the SKF measurements when the clients skin is dry and lotion- free.
Do not measure SKFs immediately after physical activity because of fluid shifts to the skin. Final Thoughts Becoming a highly skilled SKF technicians takes careful practice and precise adherence to measurement procedures.

These body types are determined by your genetics. A person with an ectomorph body type has very little body fat and muscle and struggles to gain weight. Someone with an endomorph body type, on the other hand, has a high percentage of body fat and muscle and has no problems gaining weight.
Mesomorphs have an athletic build and can gain and lose weight easily. The 4-component model of body composition measures body fat, water, mineral, and protein content to assess body composition.
By comparison, the traditional 2-component model only uses fat mass and fat-free mass to assess body composition. Body fat percentages that measure higher than that range classify someone with obesity.

The recommended ranges are:. If a fitness trainer has hrainers client with percentages below or Boost metabolic rate these levels, Antioxidant health benefits will require special attention.
This involves sending an electrical impulse through the body to measure how much resistance it meets from body fat. The two ways of delivering the electrical impulse are:. The disadvantages of these methods is that there can be some discrepancies in the measurements.
Human and computer error can also be factors. Skin caliper tests tend to be done on four points, seven points or nine points around the body.
The four-point skin caliper test focuses on the upper body, which is the danger area for fat as it can gather around the major organs. The four sites where measurements are taken are the bicepsthe triceps, the subscapularis and the anterior iliac crest. For each site, the personal trainer should take three measurements and then work out the average to get a more accurate result.
These averages are then added together and cross referenced on the grid to calculate an overall body fat percentage. Fitness instructors should be aware of the importance of accuracy in these tests to motivate their client. For example, dehydration and failing to take measurements in the same spot each time could affect the results, and the client could become demotivated if they are led to believe they have made no progress in reducing their body fat over weeks of training.
When considering whether to administer a body fat analysis test, a personal trainer should also take into account the intrusive nature of the tests. For example, for a client who is clearly overweight, it might be better to use the BMI index or hip-to-waist ratio, which would be easier to monitor and less intrusive.
