FitnessDx is a physician-designed physical fitness testing service.
Using a combination of advanced body measurements, cutting-edge biomarkers, and exercise tolerance testing we give you deep insights about your health, fitness and disease risks.
Going beyond the scale
Total body mass (aka. weight) can certainly confer health status or risks when at extreme levels. But, in many people, simple body weight may not tell the whole story. Determination of tissue distribution (body shape) and types (composition) can give a more complete picture of health and fitness.
In addition to traditional body measures, we use the seca mBCA 525 Medical Body Composition Analyzer to estimate the mass of various tissues, including fat, skeletal muscle, and water. It has been validated against the medical gold-standard for body composition testing (called "Four Compartment Model") to 95% accuracy.
With each measurement you will be provided with a report card (right) and a more detailed composition report from mBCA.
A deeper look inside
Biomarkers, often called “labs”, are measurable substances that can be an indicator of biologic state or condition. For this purpose, we are looking at labs to help determine risk of cardiovascular disease (heart attack, stroke) and development of diabetes. Even without high risks, these values can can used to track fitness and weight loss efforts. These biomarkers can be categorized in a number of ways, but we divide them as lipids (cholesterol), vascular inflammation, metabolic (blood sugar, insulin), or blood health. You can learn more about each individual marker here.
We offer a number of lab packages that give a deeper picture than standard "physical" would include routinely. You can review our Basic, Expanded, and Advanced lab panels here.
EXERCISE TOLERANCE TESTING
Quantify your cardiovascular shape
The body’s response to physical training is amazing. Everyone knows that getting in better shape will help you run faster and go farther; our exercise tolerance testing measures those physiologic improvements objectively.
FitnessDx’s functional treadmill exam quantifies cardiovascular efficiency that can be tracked over time. Our standardized protocol allows for calculation of a participant's maximum metabolic work (VO2 max) and a “FIT Score” (a predictor of 10 year survival based on these results and demographics).
Now, you won’t have to guesstimate how good of shape you are in.
FitnessDx was designed to help you track improvements in fitness and health risks over time while you are optimizing your health. Results in "moderate" or "high" categories are an indication of increased risk of poor health events (e.g. heart attack or development of diabetes). Having results in a “low risk” or “normal” category is the goal, but may not be possible in all individuals due to a variety of factors. Regardless of starting levels, improving numbers may be slow even with a consistent, good effort.
We recommend retesting every 3-4 months to help give you feedback about your efforts. Some natural physiologic and technical (lab equipment) variability is expected. So, small changes in numbers across a couple tests shouldn’t be taken as proof of progress or decline.
How to improve?
Lifestyle changes, such as improved diet and optimizing physical activities, are generally the healthiest way to improve these results and reduce health risks. Given every individual has a unique health history and goals, specific recommendations about medical care or treatments cannot be made solely based on these results. FitnessDx strongly recommends a relationship with a primary care physician to help develop a personalized plan; especially if chronic diseases present or medications are being used.
Other Health Factors
Many important health issues -- including genetics, chronic diseases (hypertension, etc.), past health events, family history, tobacco use, medications and more -- are NOT covered by this assessment. These results should be taken in the context of a broader health history in consultation with a Primary Care Physician or other qualified medical provider.
