Bod Pod body volume calculation -
During data collection, the BOD POD door is closed by a series of electromagnets aod a gasket, and the diaphragm effectively moves back and forth between the two chambers. The pressure change is roughly· ±0.
During the body volume measurement, the subject breathes normally, known as relaxed tidal breathing, unlike underwater weighing which typically requires maximal exhalation to residual volume. Thus, the relevant measurement of lung volume for the BOD POD is not residual volume, but the average lung volume during normal tidal breathing average thoracic gas volume.
This is a much easier measurement to obtain and no difficult maneuvers are required. To achieve optimal accuracy, the volume of air in the lungs must be determined. This may be done by using an estimated value based on standard prediction equations.
The effect of skin surface area is also estimated. As always, counsel the athlete sitting in front of you. First ever BOD POD: Like a cross-sectional study, you only have one data point that you assume to be accurate. If any numbers are of concern, further ask the athlete about their stress levels, sleep pattern, mood, nutritional habits, and, if applicable, menstrual pattern or any changes to it.
Multiple BOD PODs: Like a long-term study, you now have multiple data points to review. A pattern should present itself and any outliers or error will be obvious. Remember: Body composition need not be steady throughout the year. Further Reading:. A new air displacement method for the determination of human body composition.

Sounds of valves opening and closing and a fan may be heard procedure. However, no pressure changes will be felt and difficult breathing maneuvers are NOT required. All air is not equally compressible.
Air in contact with clothing and hair is more compressible than air that is not. Because the BOD POD technique relies on measuring small pressure changes, the use of a swim cap and bathing suit minimize the detrimental effects of the air during its compression.
Therefore, minimal tight fitting clothing and a swim cap are necessary for accurate results. What preparation will I need to prepare for a BOD POD test?
After your first test we suggest weeks of nutrition changes and fitness Regiment. Research has shown that a moderate, natural increase in body fat with age occurs in many individuals. Based on information from the American College of Sports Medicine, the American Counsel on Exercise, Exercise Physiology 4th Edition.
You can relax in a comfortable chair and we will fit you with a disposable mouth- piece. While just relaxing and breathing as normal the test will calculate your breaths, during a ten-minute session. We all have a unique metabolic rate. Even people with similar attributes like age, height, weight and body composition can have very different metabolic rates.
If your metabolic rate is lower than an average you may gain weight even while dieting. On the flip side if your rate is higher than normal, you may not need to diet to lose weight or you may not be eating enough to lose weight.
Your overall cardiovascular fitness level can be used as a measure of your progress over time. Additionally, the target heart rate zone information you receive from this test can be paired with a heart rate monitor to allow you to more accurately monitor your workouts and how many calories you are burning during each session.
Ultimately your workout will become more efficient and can reach higher level of fitness safely with out fatigue and muscle damage. For best results do not work out the day of the test and do not consume a large meal 1 -2 hours prior to test. Please bring running shoes, workout attire, towel and bottle of water with you the day of test.
It is also recommended that you bring a small healthy snack i. piece of fruit or protein bar for afterwards and a change of clean clothes, if desired.

| Measurement Toolkit - Air displacement plethysmography | The test-retest correlation coefficients for the duplicate BOD POD FRC measurements for the male and female subjects were 0. The mean differences between the BOD POD FRC trial 1 measurement and gas dilution FRC measurement for the male and female subjects were and ml, respectively. Neither difference was statistically significant. The correlation coefficients for these two measurements in the male and female subjects were 0. Based on these results, we conclude that the BOD POD FRC measurement in healthy males and females is both reliable and valid. Abstract The BOD POD Body Composition System uses air-displacement plethysmography to measure body volume. Publication types Evaluation Study Validation Study. The equation used for the COSMED BOD POD is as follows:. As a reference, I plugged my own BOD POD report results into this calculation and applied the activity factors see next section. The numbers were accurate to calories. Research has shown that the BOD POD may overestimate fat percentage in some i. Out of curiosity, using the Cunningham, Harris-Benedict, and Mifflin-St. Granted, it's very difficult to precisely measure energy expenditure and intake. Whether it's a predictive equation or the BOD POD report, be consistent with what value you use when counseling athletes on their diet. Energy Expenditure Results Table: Daily Activity Level. The RMR reflects an athlete lying in bed all day, only infrequently getting up to use the bathroom or walk to the kitchen. The calculated RMR is then multiplied by activity factors to estimate how many calories an athlete will burn once active. Does Menstruation Impact the Results? when body composition was measured using the underwater weighing technique. Varying hormones throughout the menstrual cycle are thought to impact hydration as the fluctuating hormones estradiol and progesterone coincide with sodium and water retention. Hormonal changes are also thought to possibly shift appetite and caloric intake. Per the research, not all menstruating women experience significant differences in their BOD POD or body composition results, or even their subjective feelings e. So we cannot make a broad assumption for all women. Ideally, and with multiple body composition measurements, a woman would be measured on the same day within her cycle as she had in prior appointments—keeping in mind that a woman may vary from the average day menstrual timeline. In reality, a collegiate sports dietitian would schedule a team BOD POD session. Rather, speak with your female athlete about the potential impact their menstrual cycle may have on their BOD POD results and ask if they subjectively feel any differences in their body dependent on the time of month. Take-home Messages:. As always, counsel the athlete sitting in front of you. First ever BOD POD: Like a cross-sectional study, you only have one data point that you assume to be accurate.
