Body composition -
Two people at the same height and same body weight may have different health issues because they have a different body composition.
Dual X-ray Absorptiometry DXA is a quick and pain free scan that can tell you a lot about your body. Example analysis from a DXA scan PDF. Although body fat endures a negative reputation, fats and lipids play critical roles in the overall functioning of the body, such as in digestion and energy metabolism.
Fat is the body's energy provider and energy reserve, which helps the body maintain a constant temperature. Fats and lipids are also involved in the production and regulation of some hormones such as, steroid hormones.
These are essential in regulating sexuality, reproduction, and development of the human sex organs, as well as in regulating the water balance in the body. Fats and lipids also have important structural roles in maintaining nerve impulse transmission, memory storage, and tissue structure.
Lipids are the major component of cell membranes. Fat serve as an energy reserve for the body, particularly as exercise progresses past 20 minutes. From a performance stand point, excess body fat lowers your work to weight ratio, This means that a heavier person would consume more energy per minute of work resulting in a lower energy economy during activity.
In addition, excess body fat can lead to additional loads placed on joint during weight bearing activities such as running, causing joint distress. Healthy or athletic body fat percentages typically allow for more optimal performances, due to the improved economy and reduced injuries.
The immune system is often impaired when body fat stores are too low. A reduced ability to fight infections means more interruptions in training and more chance of being sick on race day. For female athletes, there are some very immediate consequences of a low body fat level, including a fall in circulating oestrogen levels.
This in turn can lead to a loss of bone mass, causing problems for women in later life through an increased risk of bone fracture.
Assessing body fat can be done using the following methodologies: Hydrostatic weighing, skinfold assessment and bio-electrical impedance. Of these methods, one that is both accurate and practical is skinfold measurement.
The measurements are taken with calipers, which gauge the skinfold thickness in millimeters of areas where fat typically accumulates i.
Once the measurements are recorded, the numbers are inserted into an equation that calculates a body fat percentage and alternatively body lean mass. Skinfold is a preferred method of body fat measurement for non-clinical settings because it is easy to administer with proven accuracy and is not obtrusive with regards to the patient.
It also provides much more data than just the final composition measurement - it also yields the thickness of many sites, which can be used as bases of comparison with future results. For example, an abdominal skinfold improvement from 35mm to 24mm would show a significant improvement in that site even if the overall body fat percentage may have only reduced minimally.

However, BMI is simply a weight to height ratio. It is a tool for indicating weight status in adults and general health in large populations. BMI correlates mildly with body fat but when used in conjunction with a body fat measurement gives a very accurate presentation of your current weight status.
With that being said, an elevated BMI above 30 significantly increases your risk of developing long-term and disabling conditions such as hypertension, diabetes mellitus, gallstones, stroke, osteoarthritis, and some forms of cancer. For adults over 20 years old, BMI typically falls into one of the above categories see table above.

Your body fat can also vary by age. Your provider can also take all of these factors into account when helping you learn about your body composition and identify imbalances in body fat and lean mass you may have. There are several different tests to measure body composition. Your healthcare provider can help you decide which assessment is best for you. Your options may include:. It's important to note that some people use weight scales to measure their body composition. One study even compared the results from three different commercially available scales to a DXA scan and found the weight scales were inaccurate. A variety of factors can affect your body composition. Unlike the BMI, your body composition takes the following factors into consideration:. Your healthcare provider can help you better understand important details about the percentage of body fat and lean mass in your body and offer advice on how to move forward. If you want to change your body composition either by increasing lean mass or reducing body fat , here are some safe, effective ways to do so:. Body composition is the breakdown of body fat and lean mass that you carry. Unlike the BMI which only considers your height and weight, factors like your age, sex, hormone levels, lifestyle habits, and genetics all play a role in your body composition. If you want a holistic assessment of the state of your health, knowing your body composition is more useful than just knowing your body weight or BMI. By looking at the breakdown of lean mass compared to fat in your body, you and your healthcare can develop a plan to make certain lifestyle changes that can help you reach your health goals and lower the risk of developing certain health conditions.

| How to Improve Body Composition, Based on Science | However, the methods used to measure body composition and BMI differ. Additionally, BMI may not provide accurate results in all situations. Despite being a flawed measure , BMI is widely used today in the medical community because it is an inexpensive and quick method for analyzing potential health status and outcomes. BMI is a tool that has been used by health professionals to assess body fatness and health. This BMI table is from the Centers for Disease Control and Prevention CDC. There are a number of ways to measure body composition. However, you need more than a bathroom scale and calculator to figure out what percentage of your weight comes from fat and what percentage comes from muscle. A smart scale can help you monitor various key metrics. Muscles have a lower resistance to an electric current than fat. Skinfold measurements involve the use of special calipers that measure the skinfold—subcutaneous fat—on different parts of your body. The DEXA scan, or dual-energy X-ray absorptiometry scan, uses a low-level X-ray to measure bone, muscle, and body fat. Hydrostatic weighing involves full submersion in a water tank, using water displacement to measure body composition. Since fat floats and muscle sinks, a person with more lean body mass weighs more underwater. Bod pod is similar to hydrostatic weighing, but uses air displacement instead of water displacement to measure body composition. For this test, you sit in an egg-shaped chamber, which uses your body weight and volume to determine your body composition. Body composition provides valuable information about body fat percentage. However, your body shape is unique to you and there are uncontrollable factors that affect your body composition including:. To change your body composition, you need the right balance of physical activity and nutrition to reach your goals. Slow and steady changes work best when you want to increase muscle and lose fat. It's important to remember that some factors will remain out of your control. Before making any changes to your diet or workout routine, consult with your primary care provider or a registered dietitian for guidance. Your body composition may help you better understand your current level of health and fitness. It can also serve as a measuring tool to monitor progress when starting a new fitness or wellness program. Seek advice from a health care professional before making any major changes to your diet or exercise routine. The three somatotypes include ectomorphs, endomorphs, and mesomorphs. 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.
