Fat-free body composition -

The general protein intake recommendation is 0. However, this may vary depending on your situation. For example, if you're on a restricted-calorie diet, you need more protein to encourage your body to utilize fat instead of lean mass for energy.

A study published in the British Journal of Nutrition in August found that bumping up to 1. Make sure to get protein from lean sources like eggs, yogurt, tofu, chicken, turkey, nuts, seeds, fish and seafood, sirloin and other lean cuts of beef.

In addition to dietary protein, physical activity plays a pivotal role in maintaining and building lean mass. When you don't get enough physical activity, the body is more likely to break down muscle for energy. The old saying that if "you don't use it, you lose it," rings true when it comes to muscle mass.

In addition to helping control your weight, physical activity has a number of other health benefits such as helping to lower blood pressure, improving mood, and reducing the risk of chronic diseases such as diabetes and heart disease.

In general, a good health and fitness plan includes to minutes of moderate exercise each week, according to the American College of Sports Medicine. For optimal weight loss benefits, more than minutes per week is necessary. If you're not used to exercising regularly, start slowly and build up gradually to help reduce the risk of injury and help your body adjust.

Although a Fat-free body composition amount Fat-free body composition body fat is needed to bosy good health, excess body fat Wild Berry Foraging been found to dramatically increase the risk of diseases such as cancer, diabetes, and heart disease. Sedentary people may gain fat and lose muscle without any noticeable change in their weight. Conversely, individuals who exercise may not experience a large change in weight, yet their muscle mass is likely increasing at the same time as they are also losing body fat. A body composition analysis reveals these important shifts in body composition that a scale cannot.

Fat-free body composition -

Other advanced methods discussed in research journals include isotope dilution, neutron activation analysis, magnetic resonance imaging, and dual-energy x-ray absorptiometry. This error factor may be increased dramatically due to the skill or lack of it of the technician taking the measurements.

The following sections will focus on three body fat measurement techniques that are often accessible to fitness professionals: hydrostatic weighing, bioelectrical impedance, and skinfolds.

Hydrostatic Weighing Hydrostatic weighing is a valid, reliable and widely used technique for assessing body composition. It has been labeled the "Gold Standard" or criterion measure of body composition analysis.

It is based on Archimedes' principle. This principle states that an object immersed in a fluid loses an amount of weight equivalent to the weight of the fluid which is displaced by the object's volume. This principle is applied to estimate the body volume and body density of individuals.

Since fat has a lower density than muscle or bone, fatter individuals will have a lower total body density than leaner individuals. As the person is being submerged, the air in the lungs must be exhaled completely.

The air remaining in the small pockets of the lungs following a maximal expiration is referred to as the residual lung volume. The residual lung volume may be determined using a number of laboratory techniques or it is often estimated using age, height, and gender-specific equations.

Once your body weight, the underwater weight, and the residual lung volume are known, total body density may be calculated. From the total body density, the percent body fat can be estimated using the appropriate age-gender equation.

One limitation of hydrostatic weighing is that it is based on the two- component model fat and fat-free mass which assumes when calculating total body density that the relative amounts and densities of bone, muscle, and water comprising the fat-free mass are essentially the same for all individuals, regardless of age, gender, race or fitness level.

It is now known that this is not the case. For instance, the fat-free body density of young Black men is greater than that of white men. Because of this, the lean body mass is overestimated and the body fat is underestimated for many Blacks.

Also, after age 45 to 50, substantial changes in bone density, especially in women, invalidate the use of an assumed constant value for fat-free body density when converting total body density to percentage of body fat. This is why age and gender specific equations need to be used for estimating body fat.

As researchers learn more about age-related changes in bone mineral, hydrostatic weighing will eventually provide a more accurate prediction of body fat for older men and women. Bioelectrical impedance analysis BIA is based on the fact that the body contains intracellular and extracellular fluids capable of electrical conduction.

A non-detectable, safe, low-level current flows through these intracellular and extracellular fluids. Since your fat-free body weight contains much of your body's water and electrolytes, it is a better conductor of the electrical current than the fat, which contains very little water.

So this technique is essentially an index of total body water, from which fat-free mass is estimated. The popularity of the BIA method has grown significantly over the last few years because it is painless, quick, and easy to administer the test.

To take the test, you lie on a testing table or floor and electrodes are attached to your hands and feet. You do not feel a thing as the current passes through your body. Average time for administering this test is about 10 minutes.

No eating or drinking within 4 hours of the test 2. No exercise within 12 hours of the test 3. Urinate within 30 minutes of the test 4. No alcohol consumption within 48 hours of the test 5.

There is a tendency for BIA to overestimate percent body fat in very lean clients and underestimate body fat in obese clients.

All in all, if the guidelines for testing are followed, the BIA method is a satisfactory method for assessing body composition of most people. Skinfold Method The skinfold method of measuring body fat is a practical, economical, and administratively feasible field technique for body composition analysis.

It involves measuring the skinfold subcutaneous fat thickness at specific sites of the body. Most equations use the sum of at least three skinfolds to estimate body density from which body fat may be calculated.

Skinfold measurement does not require expensive equipment and it can be routinely incorporated into many health promotion settings. Skinfold technicians can be trained rather easily, but must practice on at least clients before the skinfold technique is mastered.

When using the skinfold method, it is assumed that the distribution of subcutaneous fat and internal fat is similar for all individuals.

This assumption is not fully supported. It is now known that older subjects of the same body density and gender have proportionately less subcutaneous fat than their younger counterparts.

There is considerable biological variation in the distribution of subcutaneous, intermuscular, intramuscular, and internal organ fat due to age, gender, and degree of fatness Heyward, Accuracy of Skinfold Measurements The accuracy of the skinfold method is dependent on the technician's skill as well as the type of caliper and the skinfold prediction equation used.

Reasonably priced plastic calipers have a less precise measuring scale, and often provide variable pressure and a smaller range of measurement. Despite this, a number of researchers have reported only small differences between skinfolds measured with high quality calipers and plastic calipers for highly skilled technicians refer to Guide to Skinfold Caliper for more information on where to purchase calipers.

However, plastic calipers are not recommended for use by untrained technicians. To assure accuracy, the skinfold technician must follow standardized testing procedures: 1.

Take all skinfold measurements on the right side of the body. Carefully identify and mark the skinfold sites. Place the thumb and index finger approximately 3 inches 8 cm perpendicular to the skinfold, following the natural cleavage lines of the skin.

Do not release the skinfold during the measurement. Always release the caliper jaw pressure slowly. The skinfold measurement should be taken 4 seconds after the pressure is released. You should take a minimum of two measurements at each site. It is advisable to take measurements in a rotational order rather than consecutive readings at the same site.

If your values differ by more than 1 mm, take additional measurements. The client's skin should be dry and free of any oils and lotions. Skinfold measurements should not be done immediately after exercise due to the shift of body fluid to the skin. Fortunately, the time of day or the phase of the menstrual cycle will have little effect on the skinfold measurements.

As with many skills, the more you practice the better you will become at measuring skinfolds. It always helps if you have another trained technician to compare your results. One alternative for obese clients would be to use fat-specific equations Segal et al.

Measuring Sites for Women Triceps: Take a vertical fold on the posterior midline of the upper arm halfway between the top of the shoulder and the elbow joint.

Keep the elbow extended and relaxed. Thigh: Take a vertical fold on the front aspect of the thigh, midway between the top of the knee cap and the hip.

Suprailium: Take a diagonal fold above the crest of the ilium hip- bone , at the spot where an imaginary line comes down from the anterior line of the armpit anterior axillary line. Measuring Sites for Men Chest: Take a diagonal fold half the distance between the anterior axillary line line of armpit and nipple.

Target Body Fat Keep a record of each client's estimated body fat. This is very useful information for you to track the success of the exercise program you have prescribed. It will also give you insight about changes you feel may be necessary. Knowing a person's body fat will help you determine a more realistic target body fat and body weight for them.

The actual fat weight for this person is X. Therefore, to reach this new body fat level she needs to lose 7 lb of body fat. The following table summarizes the steps for calculating target body fat and target body weight.

Several people are now on a quest of having a significant percentage of lean body mass or as little fat as possible. Sure, this looks good, but it also has many other benefits!

Helps you battle disease More lean body mass makes you less likely to become sick or develop health problems such as heart disease or diabetes. It affects your metabolism and energy levels. The more fat-free body mass you have, the higher your metabolism.

The explanation for this is simple — muscles require energy in calories, while fat cells do not. So, the more lean body mass you have, the more calories you burn throughout the day, even when you rest! Increases your strength and agility. At around 30 years, our muscle mass typically begins to decrease.

This results in a gradual loss of strength and mobility. Strength training enables us to maintain or even gain lean muscle mass after the age of This means we can remain mobile and strong for many years to come. Contributes to strong bones.

The bigger and stronger our active muscles are, the more significant is the force on the bones. This forces the muscles to adapt and become stronger by having higher bone mineral density! Higher lean body mass also stabilizes and protects our joints while decreasing the likelihood of osteoporosis and osteoarthritis.

To the most important part: how can you reach a lean body? Increasing your lean body mass is a two-factor equation: increase muscle mass and decrease body fat mass.

Here are five easy ways to increase lean body mass. Incorporate resistance training into your regular exercise routine. To build more muscle, you must incorporate progressive resistance training, most commonly weightlifting or bodyweight training callisthenics , into your training routine.

Eat protein! The right amount of protein consumption helps increase and maintain lean body mass and has many other benefits, such as healthier hair and skin and building immunity. You can also benefit from protein intake during exercises, primarily if you work out for more extended periods and intense.

When you consume a sports drink that combines carbohydrates with protein, your muscles will use the carbohydrates as fuel and protein as a signal to increase muscle protein synthesis muscle building.

Recovery is an essential part of your workout! Training progress and building muscle happen only when regeneration surpasses the previous ability. This is called supercompensation. Exercise increases your lean body mass, but it also increases the release of stress hormones. This, in turn, increases the muscle protein breakdown.

If you want to minimise muscle protein breakdown, consume enough daily protein. Get adequate amounts of sleep each night.

Sleep is crucial for increasing lean body mass. Try sleeping seven to eight and a half hours for multiple complete sleep cycles of REM. These cycles appear and repeat in approximately 90 minutes — during this time, most regeneration and adaptation occur.

The more cycles you miss, the less recovery you will get. Dieting can help you get rid of unwanted body fat and increase lean body mass, but there is one crucial thing to note. Extreme diets increase muscle protein breakdown.

Besides watc hing your calories, you should also pay attention to increasing your fibre intake. It makes you full for longer and slows the increase of blood glucose after a meal.

Black beans, berries, sweet potatoes, and other high-fibre foods are digested at a much slower rate, causing a slow, steady stream of glucose into your bloodstream.
