New Video: Overview of Metabolic Testing at SSMI

Scottsdale Sports Medicine Institute takes great pride in the on-site metabolic lab Dr. Carfagno has created.  If you have followed any of our social media or have visited our office you have probably been exposed to some of the metabolic testing we offer at our office.

In the past we have uploaded short previews of the DEXA Body Composition scans, Resting Metabolic Rate (RMR) and VO2 max testing including what the testing procedures look like.  Today we have uploaded a general overview of all 3 tests including a sneak peek at the reports and normative tables that are covered with the consultation included with the testing. 

Make sure to watch the video, and read the brief description of each test included below.  Free to contact us with any questions and to schedule your next appointment for metabolic testing!!


DEXA Body Composition scan

Dual Energy X-Ray (DEXA) absorptiometry is the most accurate and detailed measurement of body composition.  A low dose of X-ray radiation is used to report a 3 component model of body tissue including body fat mass, muscle mass, and bone mass.


Resting Metabolic Rate

Resting metabolic rate (RMR) is the measure of energy expenditure when you are at complete rest.  The significance of RMR is that it represents how many calories per day you need to maintain basic physiological function.  While there are many calculators that estimate energy expenditure, the testing in our lab uses the measurement of oxygen consumption at rest to obtain the actual amount.   This is one of the key bio-markers we use for dietary planning.


VO2 Max

VO2 max has long been the gold standard for cardiovascular fitness category in athletes. Conversely, the applications for VO2 are just as if not more important for clinical populations as a marker of health.  Where cardiac output is measured to determine the rate that blood flows through the circulatory system, VO2 max is measured to determine how well the tissues are utilizing oxygen being delivered as well as the ability for the circulatory system to remove metabolic waste such as carbon dioxide and lactic acid.  In essence, a higher VO2 indicates better levels of health/ fitness.

Other services offered in the metabolic lab

The metabolic testing offers an empirical evaluation on your current condition/ fitness/ health but what's next?  Each of the testing procedures includes a consultation on your results with a general overview, but sometimes it takes a more in depth approach to make the results meaningfull.  This is why we offer extended exercise consults with an exercise physiologist to cover a more comprehensive workout plan to take your training to the next level.  These one time consults cost $25 for a 30 minute session to get down to the nitty gritty of what you have been doing, what your goals are, and ultimitely writing an exercise prescription to get you there. Beyond that, we are also offering personal training sessions in increments of 15, 30 or 60 minute sessions to focus on form, technique and boosting your confidence to be able to take ownership of your training at home or at the gym.  Keep posted and follow us on all of our social media as we will be adding other services and testing in the near future.
