FAQ

What does a DEXA Scan measure?

DEXA Scan measures total body weight, fat, visceral fat, lean mass and bone mineral density.

Why is my DEXA body fat percentage so much different than what is recorded from other tests?

DEXA scan takes several measurements where as other tests use standardized equations that can account for variables like bone density. DEXA is a direct measurement of your specific body composition.

How much radiation will I be exposed to?

Radiation exposure is minimal, however if you have a previous health disposition or concern, please discuss with your primary care doctor prior to making an appointment. Women who are pregnant are not advised to have a scan.

Can I eat or drink before having a scan?

Yes, you can have a small meal and water before a scan. Please note, if you are receiving additional tests at the same time, those tests may require fasting.

Is there an age requirement for a DEXA scan?

Yes, there is a minimum age requirement of 21.

What does Vo2max test measure?

Vo2max is your aerobic power, or maximal oxygen uptake. As exercise intensity increases so does oxygen consumption. However at some point, you reach a maximum intake level and you enter an anaerobic state. Vo2max is the highest rate at which your body is able to consume oxygen.

How is the test performed?

The test is performed on ether a bike or treadmill. You will wear a heart rate track and special mask. You begin the test with normal breathing and as intensity increases, you will work harder until you reach exhaustion. At that point of maximal fatigue, the test is stopped and allow your heart rate to recover, all the while your oxygen uptake is being recorded.

Can I eat or drink before my test?

Do not eat or drink anything other than water at least 4 hours prior to your test. Do not consume alcohol or nicotine 24 hours prior to your test. You may take medications and vitamins, however please refrain from any thermogenic aids.

Can I exercise the day of my test?

It’s important to have efficient rest prior to your test, therefore we recommend to refrain from all exercise 24 hours prior to your test. You may exercise after you have the test performed.

What should I wear to my test?

Treadmill Testing - Loose-fitting clothing, such as joggers, shorts, leggings, breathable t-shirts, and athletic shoes is best.

Bike Testing - Cycling attire (bibs, cycling shorts) and cycling shoes.*

*NOTE: Height Limit of 160cm to 175cm (Anything below or above this height range may not be optimal)

Why is Vo2Max important?

Vo2max is an indicator of overall fitness and health. This score reflects your cardiovascular efficiency by identifying the exact amount of oxygen your body uses at your current fitness level. It then feeds you the heart rate you should target to maximize results. This is the same target heart rate that will optimize your body’s ability to burn fat.

What factors affect Vo2Max?

The biggest factors include, but aren’t limited to:

Genetics

Age

Sex

Body composition

Fitness level and activity

What else does it measure?

Vo2max test also records your respiratory exchange ratio, which shows your fat-burning and carb-burning zones, and how many calories you burn during active exercise.

Can I increase my Vo2Max?

Yes, aerobic power can increase between 6 and 20 percent with proper training and conditioning. Initial increases in Vo2max are significant in the beginning. Steady-state aerobic conditioning and HIIT are both effective ways to increase Vo2max, but research shows that HIIT is the prefered method. The key is consistency in training and pushing your intensity to the limit.

Why is increasing Vo2Max important?

Vo2max is proven to be a powerful predictor of cardiovascular disease and mortality in men and women. Research has found that a person’s Vo2max is a better indicator of mortality than tobacco use, hypertension, elevated blood lipids and diabetes. Those who have a higher Vo2max are less likely to have a heart attack, therefor will likely live longer than those who have a lower Vo2max.

What is RMR analysis?

RMR stands for resting metabolic rate, this is the amount of calories your body burns at rest. Because your body burns (uses) calories for everyday functions like breathing, blood circulation, digestion, etc. there is a minimum number of calories you need to consume. Daily movement such as brushing your teeth, driving, doing laundry, etc. requires additional calories for proper function and to maintain weight. An RMR analysis measures how many calories you burn just by laying in your bed all day.

Why do I need to know my RMR?

There are several reasons to know your RMR. The primary reason is to ensure your metabolism is functioning properly. If your RMR is lower than expected, there may be underlying issues that need to be addressed. A low RMR can also mean you are not consuming enough calories necessary for daily functions, so your body is saving energy by slowing down your metabolism.

The secondary reason is to stabilize weight and/or weight loss and identify how many calories you need to achieve your goals. The speed of your metabolism will determine how many calories you need to consume to lose, maintain or gain weight.

What affects my RMR?

RMR is very sensitive, and can be affected by several factors including:

Genetics

Environment

Hormones

Efficiency of digestion

Quantity of intake

Stress

Exercise

How should I prepare for my RMR analysis?

Avoid food, tobacco, alcohol and caffeine at least 6 hours prior to your test. Do not exercise for at least 12 hours prior to testing.

What should I wear to my test?

We suggest loose, comfortable clothing.

How is the test performed?

The test is very simple. You will lay down in a reclining chair and breath into a tube which will collect your exhaled air and analyze it. The test takes approximately 15-20 minutes and your test results woll be available immediately.
