Most importantly is being in a fasted state as water and food bulk can be misinterpreted as lean tissue. Another drawback is that one cannot perform skin fold measurements on themselves.

Hydrostatic weighing for bodybuilding -

Once you can get a consistent reading, you have all the info you need to gauge your progress as you work to transform your body. Your goal when you test your body fat isn't to get accurate measurements, it's to get consistent measurements.

Take that to heart and you'll do fine. These instructions will help you perform a three-site Jackson and Pollock skinfold test using any inexpensive body fat calipers.

You may scoff at using inexpensive plastic calipers rather than more expensive varieties you see trainers using in gyms, but you shouldn't.

I have performed more than 15, body fat measurements using a wide range of methods and I can attest that these simple tools and the following method are consistent with more complicated seven-site and nine-site testing.

When taking a skinfold, the basic idea is to "pinch and pull. The sites used to determine body fat are usually identified by bony markings or body parts that are consistent between people, like a nipple or navel.

This enables you to accurately find a specific point on the body no matter your overall body composition, and find the same point again on anyone else. When you first start, I recommended that you use measuring tape to find the exact point you need, marking the spot with a felt-tip pen.

As you become more practiced, you will be able to ditch the extra tools. Imagine a vertical line running straight down through your right nipple. This reference point is called the "midaxillary line. Pinch that spot diagonally, or have your helper do it.

Make a vertical fold one inch to the right of your navel. If you have trouble getting a consistent vertical fold, it's OK to use a horizontal fold instead. There isn't much of a difference, but you should note if you do something different from normal and use that method in the future to stay consistent.

Find the midpoint between the hip and the knee and use a vertical fold. Unless you take out measuring tape and a marker for precise measuring, I recommend using your hand to measure rather than eyeballing it.

For instance, I use the distance between the tip of my thumb and pinky from the top of the knee, which for most people is fairly close to the midpoint. Since I do it that way every time, I'm able to be consistent. Find the midpoint between the acromion process the bony knob on top of your shoulder and the point of the elbow.

You'll need a helper for this. Use a vertical fold. This site is found below the armpit at the top ridge of your hip bone, called the iliac crest or suprailiac, taken on the side. Gently press the area and find the ridge of the hip, going just above the bone. Measure using a diagonal fold.

As with men, use the midpoint between the hip and the knee. As I mentioned, I normally use the distance between the tip of my thumb and pinky from the top of the knee, which is fairly close to the midpoint for most people. Measure using a vertical fold.

Enter your skinfold measurements into our Body Fat Calculator to get your results! When people talk about wanting to lose weight, usually what they're really talking about is losing fat.

Ideally, when you lose weight, you'll lose as much fat as possible, and as little lean mass as possible. It can actually be good for you to gain weight in the form of lean mass muscle , since having more muscle actually helps you burn fat.

So a more accurate and practical goal than just losing weight would be instead to lower your body fat percentage, also known as changing your body composition—the ratio of fat mass to lean mass that makes up your body.

When you lower your body fat percentage, you'll end up looking more fit, whether you got there by losing fat, gaining muscle, or a combination of both. What constitutes a "healthy" level of body fat depends a lot on your sex and your goals. If you're not worried about keeping your body fat low for aesthetic or performance goals, then it's perfectly OK to have the goal of keeping your body fat percentage anywhere below "obese" and above "essential fat levels.

Use that number to gauge progress, because the scale doesn't always tell the whole story. You might be losing weight or gaining weight, but where is that weight coming from?

Muscle or fat? From a planning perspective, having your body fat percentage measured can help you determine realistic goals. Knowing your ratio of fat mass to lean mass will make it easier to determine how many pounds of fat you can likely lose each week. For instance, if you have a goal to lose 15 pounds in three months, knowing what percentage of your body composition is actually fat can help you decide whether that goal is reasonable.

Changes in your fat and lean mass weight can also allow you to make smart decisions about your programming. For example, if you lose lean mass, it means your nutrition probably needs a second look or that you may be training way too much.

For most people, the ultimate goal is to have a better looking, healthier body, so don't become obsessed with this or any other measurement.

It's OK to use it, if only to put a number to the cosmetic changes you see in the mirror or track the effectiveness of your nutrition and training. But consider making attainable progress goals , too, like getting through a training program without skipping workouts, or eating a vegetable every day.

These are easier to control than outcome goals, like achieving a certain body fat percentage by a certain date, which rely not just on the work you put in but a whole host of biological processes that happen under the surface.

Achieving these other goals will help motivate you to stick with your program and make the process and your fitness lifestyle more satisfying. Do you know what your body fat percentage doesn't measure? Your health, your value as a person, or your skills as an athlete.

The fat free mass exists primarily as the chief structural and functional component of the human body. Fat mass varies considerably between individuals, in terms of absolute amount.

There are numerous methods of evaluating body fat, for both the clinical setting and in the field. The degree of accuracy associated with each procedure, increases as we move from the field to the clinical setting, such as skinfold measurements compared to DEXA. Some methods of measurement are more suitable for one sample group than another, for example the Body Mass Index BMI is more suited to measuring body composition in sedentary folk than athletes, due to the fact that athletes depending on their chosen sport will have a higher lean body mass and may fall into the wrong category by BMI standards rugby players, bodybuilders.

A more suitable approach to measuring a group of athletes would be the skinfold measurement as it would provide a more accurate prediction of percentage body fat for that particular sample group Than BMI.

Below are numerous methods used for the measurement of body fat and a brief summary of how they work. Archimedes' principle is the theory on which this technique for measuring body composition is based.

It states that when a body is immersed in water, it is buoyed by a counterforce equal to the weight of the water displaced. The density of body fat is less than that of water, therefore contributing to the buoyancy of the body, as does air in the lungs.

Muscle and bone tissue have a greater density than that of water and can cause a body to sink, therefore an individual with greater fat free mass but the same overall body mass, will weigh more in water due to the higher body density and lower percentage body fat.

Although hydrostatic weighing is considered the "standard" when measuring body composition, there are numerous sources of error associated with the procedure. The formulas used to convert body density to percent fat assume a density of 0. However the density of the fat free mass varies with age, gender, and ethnicity, use of a single general formula to convert body density to percentage body fat for all populations would therefore result in systematic errors.

This method is based on a two compartment model of body composition, fat mass and fat free mass, based on Boyle's law it uses the inverse relationship between pressure and volume to derive body volume for a subject. If both volume and bodyweight are known body density can be calculated by using the following equation:.

The change in pressure and volume between the empty chamber and the chamber with the subject present can be used to calculate the volume of the subject, since one side of the equation is already known.

A skinfold thickness is two layers of skin and two layers of fat. This technique is based on the principle that the amount of subcutaneous fat is proportional to the total amount of body fat. However, age gender and ethnicity all have an effect on the proportion of subcutaneous fat to total fat, 5 which means that these variables must be considered when using the regression equations to convert sum of skinfolds to percentage body fat.

Assuming that the correct technique has been used and that the correct equations have been applied, the prediction of percentage body fat has an accuracy of ±3. Is a relatively easy to administer method of measuring body fat percentage.

Bioelectrical impedance analysis works by determining the electrical impedance of the body tissues, which provides an estimate of total body water, which can be used to estimate fat free mass and percentage body fat.

It involves the passing of a small electrical current through the body and measuring the impedance to current flow. Fat free tissue is a good conductor of electrical currents, therefore body fat impedes current flow, and the impedance to current flow is inversely related to the fat free mass and total body water, both of which can be estimated by using this technique.

Generally bioelectrical impedance analysis yields similar results to skinfold measurements with regards to percentage body fat estimates, but the protocol that MUST be followed by the subject make it a little difficult.

Is the latest technology used in the assessment of body composition. This method measures bone mineral density, lean mass and fat mass, through the use of two x-ray beams which traverse the body. The energy is then collected by a detector after it has been attenuated by the bone and soft tissue through which it has passed.

The number of photons per unit of area is corrected for soft tissue by linear, two dimensional interpolation. The values are then summed to estimate total bone mineral content. Soft tissue is resolved by using mass attenuation coefficients from tissue equivalent standards for fat and fat free mass.

DEXA is considered the NEW standard in the measurement of body composition. Chemical ingestion and the subsequent analyses of the tissues is the only direct method of evaluating body composition, which is a totally impractical approach in humans. DEXA, hydrostatic weighing and plethysmography are highly accurate but expensive methods requiring clinic settings to perform the test, making them unsuitable field methods of measurement.

Bioelectrical Impedance Analysis and skinfold measurement however are inexpensive, easy to perform and can be completed in relatively little time. The protocols which have to be in place when using the BIA method also pose a problem for an accurate estimation of percentage body fat, leaving skinfold measurement as the current forerunner for accurate field testing.

In modern society obesity has become a growing concern for the health care practitioner.
