Chapter 1
Shows the Total Body Water within the body, divided into Intracellular Water and Extracellular Water.​ Intracellular Water (body water inside cells) and Extracellular Water (body water outside cells) make up Total Body Water.
ECW/TBW is a measure of compartmental fluid distribution and shows, as a ratio, how much of your total body water is extracellular.
Taking multiple InBody Tests will establish your normal fluid status and help determine any imbalances. As a general guide, check to see that your ECW/TBW is below 0.390.
WHY THIS MATTERS
This graph lets you quickly understand if you have occasional inflammation or swelling in your body resulting from strenuous exercise or activity. You can also use this to give context to LBM. High LBM and a high ECW/TBW ratio usually indicate excess body water—not just muscle.
Chapter 2
This section shows how much intracellular and extracellular body water (lb or L) is contained in each of the body’s five segments. Health professionals can use this output to evaluate body water distribution
This graph displays the ECW ratio in each of the body’s five segments. Caregivers can use this data to more precisely identify the location of fluid retention and fluid imbalances in each segment.
​
It is also important to note that since Extracellular Water is a part of Fat-Free Mass, an elevation of ECW/TBW can increase Fat-Free Mass in that segment. Because of this, any imbalances in the Segmental Lean Analysis should be evaluated for a difference in segmental ECW/TBW to determine if the cause of the imbalance is due to fluid retention rather than muscular imbalance.​
WHY THIS MATTERS
With chronic inflammation, it is crucial to prevent disease progression and treat the current state of inflammation. Increases in segmental ECW/TBW may be indicative of poorer health status. Therefore, tracking changes in segmental ECW/TBW can be used to monitor injuries, disease progression, and recovery.​
This graph displays some of the most vital measurements from your previous tests (up to 8). With Body Composition History, you can easily spot trends and track your progress over time.
At the bottom of the Result Sheet is the Body Composition History graph, which automatically tracks your Weight, Skeletal Muscle Mass, Percent Body Fat, and ECW/TBW measures from recent tests.
The purpose of this graph is to let you monitor positive and negative changes in body composition so you can adjust your diet and exercise plan to get the results you desire.
Let’s examine how to track positive and negative body composition changes by looking at the example above. These results represent an athletic, D-shaped individual whose goal was to gain muscle and lose body fat.
The Body Composition History graph makes it easy to spot when positive body composition changes occur. For instance, a gradual increase in Skeletal Muscle Mass and decrease in Body Fat Mass over the past few tests indicates that you’ve made excellent progress towards improving your overall body composition.
WHY THIS MATTERS
By any measure, this indicates that you are on the right track to achieve your goals. You should continue to follow your diet and exercise routine and closely monitor your progress using Body Composition History.
The Body Composition History graph also makes it easier to spot negative body composition changes. For example, a drop in body weight may initially appear like a positive change, but regular testing may show that this trend was due to muscle loss, not fat loss.
WHY THIS MATTERS
On the right-hand side of your Result Sheet, you will find a series of additional outputs. The InBody Test administrator can customize these outputs based on your specific goals.
Intracellular Water (body water inside cells) and Extracellular Water (body water outside cells) make up Total Body Water. Both ICW and ECW are important to monitor, but assessing Extracellular Water, in particular, can provide deep insights.
WHY THIS MATTERS
Segmental ICW Analysis reveals segmental differences in muscle. High ICW is a marker of healthy, metabolically active muscle. Segmental ICW can help assess which regions have better muscle mass/hydration.
WHY THIS MATTERS
Segmental ECW Analysis reveals whether segmental water retention is present. High segmental ECW, especially when localized (e.g., in one leg), can indicate Lymphedema, insufficiency in blood/water flow in the area, over-training or injury, or post-surgical swelling. Localized increases in ECW may point to inflammation, trauma, or infection in that body segment.
At the top, you have Intracellular Water (body water inside cells) and Extracellular Water (body water outside cells), which make up Total Body Water.
WHY THIS MATTERS
This value is the weight of the protein and mineral content in your body.
WHY THIS MATTERS
Lean Body Mass (LBM) is the sum of your ICW, ECW, and Dry Lean Mass. LBM is the weight of everything in your body except fat; for this reason, it is also called Fat-Free Mass. Lean Body Mass includes muscle, water, bones, and organs.
WHY THIS MATTERS
Below Dry Lean Mass is Body Fat Mass. This value reveals how much body fat, both surface level (subcutaneous) and internal (visceral), makes up your weight.
This section shows how your Weight, Skeletal Muscle Mass, and Body Fat Mass compare to the healthy average range of people of the same height and sex. With Muscle-Fat Analysis, you get a better understanding of where your current body composition is so you can make any changes to get it to where you would like it to be.
Muscle-Fat Analysis is a favorite output for many people because it provides an easy-to-understand overview of body composition and helps narrow the focus of health goals.
Muscle-Fat Analysis has three components:
The Muscle-Fat Analysis also tells you whether you have a healthy balance of SMM and Body Fat Mass in respect to your weight.
This section displays your body fat percentage, or Percent Body Fat (PBF), and Body Mass Index (BMI), as well as the healthy ranges for these measurements.
Body fat percentage is a division of your body fat mass by your total weight and a much better indicator of your risk of obesity than BMI.
BMI is determined by dividing your weight by your height squared. BMI is just a single value that does not differentiate between fat or muscle mass. If you use BMI to track your fitness progress, you will never know if the changes were to fat or muscle.
BMI may also oversimplify health risks. Two people with the same height and weight would have the same BMI and health risks—even if one of them has a healthy amount of fat and high muscle mass.
On the other hand, PBF puts your weight into context by showing how much of it is fat mass. Tracking changes in your body fat percentage lets you focus on actual fat loss, not just weight loss, which can also come from muscle mass.
WHY THIS MATTERS
The InBody 970S provides advanced body composition metrics in the Research Parameters section of the Body Water Result Sheet. Professionals use these outputs for research purposes and to further elevate assessments with additional actionable health data.
Intracellular Water (ICW) is water inside of the cells (includes the water in the muscles, organs, and other body tissues). The numeric ranges in parentheses represent an average range for users of the same height and sex.
Extracellular Water (ECW) is water outside of the cells (included in the blood and interstitial fluids). The numeric ranges in parentheses represent an average range for users of the same height and sex.
Many people don’t understand the principles of caloric intake and, when trying to lose weight, consume too few calories. Although this choice may be effective for weight loss, InBody devices show that a significant portion of what’s being lost is, in many cases, Fat-Free Mass.​
WHY THIS MATTERS
Phase angle represents the integrity, or strength, of cell membranes and can be a more sensitive indicator of health status when physiological changes are not apparent. Phase angle value fall between 4 and 6 degrees for women and 5 and 7 degrees for men, with a higher phase angle indicating higher cellular integrity. In athletic individuals or those with naturally high muscle mass, these values may be higher than the average range, indicating above-average cellular health. Phase angles that fall below the range are not necessarily indicative of poor health but should be monitored to ensure that they do not decrease progressively.
