Introducing the DEXA – Body Composition Scan

Did you know that your body is comprised mainly of bone, muscle, and fat? Together they help you perform daily functions. However, they may sometimes cause pain. To help our clients achieve their health goals, we first determine what their bodies are comprised of using a body scan. Specifically, the Gold Standard in body composition testing – the DEXA.

What is the DEXA?

The DEXA Scan, Dual-Energy X-ray Absorptiometry scan, is referred to in short as DEXA or DXA. The DEXA is used to measure overall body composition including Body Fat %, Lean Mass %, Visceral Fat %, and bone density.

Due to its ease of use and accuracy, the DEXA is found in Sports Science/Human Performance Labs throughout some of the best universities in the nation.

Body Composition Alternatives

  • BMI: An attempt to quantify the amount of tissue mass (muscle, fat, and bone) in an individual, then categorize that person as underweight, normal weight, overweight, or obese.
  • Bio-impedance: Value derived from the mass (weight) and height of an individual
  • Bod Pod: This method uses air displacement plethysmography to calculate body composition.  Tight clothing is required so the test does not register extra air displacement which can increase reported fat levels.
  • Hydrostatic Weighing: also referred to as “underwater weighing”, “hydrostatic body composition analysis”, and “hydrodensitometry” is a technique for measuring the mass per unit volume of a living person’s body. It is a direct application of Archimedes’ principle, that an object displaces its own volume of water.

These are common alternatives often used incorrectly as a substitute for body composition health. Not only can they be dangerously misleading due to their inaccuracy, but they are also cumbersome and inconvenient.

For example, if you have a BMI of 25 kg/m2, you are considered to have a body fat percentage ranging from 10 to 35%. When you use alternative methods, you may see a margin of error range from 5 to 15%.

Why we chose the DEXA

Using the DEXA allows us to use the most accurate data points to create personalized programs for improved recovery, rehab, nutrition and performance.

DEXA Body Scan’s accuracy and precision range fall within 1 to 2% margin of error.
It provides additional information that BMI and alternative testing methods cannot, including:

  • Visceral Adipose Tissue (VAT): This is a leading predictor of longevity, metabolic syndrome, and cardiovascular disease. The centralized location of VAT is important as it may indicate future complications.
  • Skeletal Strength: Bone density measures help determine your risk for osteoporosis, and how you compare to others.
  • Muscle Symmetry: helps to identify how your lean, fat, and bone mass compares in each region of your body
  • “Skinny fat” and sarcopenia risks, which has been found to be an important predictor of cognitive performance

Infinity Sports and Dari Motion

DARI Motion

Biomechanics play an important role in health, wellness, workplace health and safety, performance and research of the body. You might be asking, what are “biomechanics”? Well, biomechanics is the study of the mechanical laws relating to the movement or structure of living organisms.

As an active individual whether you’re an athlete, weekend warrior, fitness enthusiast, or your job is physically demanding; the study of your biomechanics can help solve issues that may or have already caused injury or pain.

What is DARI Motion

DARI Motion is a markerless motion capture system used to acquire the most precise, accurate and comprehensive biomechanics data in the industry. 

Due to its industry leading precision and accuracy the DARI Motion is able to track changes over time with sub-millimeter accuracy. This provides us with accurate information needed to make immediate, informed decisions to adjust and guarantee each rehab, performance or recovery program is meeting your exact needs and our expectations. 

The Dari Motion Tracks: 

  • 21 bone segments, nine joints, with six-degrees of freedom
  • Kinematics and kinetics in all planes
  • Range of motion
  • Joint torques
  • Internal/external rotation at the hip
  • Shoulder ab-duction
  • Anterior/posterior coronal deviation
  • Neuromuscular engagement, center of mass sway in all planes
  • All joints in space

DARI’s patented, 3rd-party validated kinetic capture collects kinetics without force plates. That means DARI can measure joint torques, ground reaction forces, and other force measurements without restricting the subject’s natural movement.

Why We Chose DARI Motion

Dari Motion is the Gold Standard and the most advanced, precise and accurate motion capture system. In order for us at Infinity Sports Institute to provide our athletes, patients, clients and members with the remarkable care, programs and outcomes we require industry leading technology and data.

The DARI Motion can be found at The Infinity Sports Institute Sports Science Lab, the only Sports Science Lab available to the public outside a University setting, in South Florida.

DARI Motion Accuracy

Most other markerless systems use a single consumer-grade depth camera originally developed for console gaming. These lack accuracy, capture a limited amount of the body, and can’t capture explosive, high-speed motions at their native 30 hz framerate.

Traditional motion labs require manual application of reflective markers on the body, causing up to 20% marker-placement error between sessions. Marker-based systems can not accurately track biomechanical data over time.

DARI uses eight high-speed cameras placed around the subject and a state-of-the-art computer-vision engine to collect whole-body data–including the fastest motions.

DARI Motion Speed

Marker-based motion analysis requires up to 45 minutes of marker placement for every session. Traditional marker-based analysis of a single human motion requires days of intensive data compiling and error-correction. By the time the data has been processed, the window of application will have passed. Therefor we will not have the chance to make accurate decisions on time. 

The DARI Motion has zero markers and zero set up time. A complete body motion analysis takes under 5 minutes allowing us to scan 50 – 100 individuals per day! The DARI takes thousands of data points comprising each motion and processes them in under a second, that’s what we call FAST

Knowledge is Potential Execution is Power

Quantification of data is useless if there is no action. The Dari Motion Provides easy-to-read reports, which our Performance and Sports Science Lab teams can explain to a 1stGrader! These reports allow us to take action steps to improving your health, performance and reducing your risk of injury. These reports include: 

  • Muscle-mapping and injury vulnerability 
  • Custom scoring and dynamic narratives 
  • Data integration with other devices
  • Custom exercise suggestions
  • Single and multiple motion reports

Who should take advantage of the DARI Motion System?

The Dari Motion is used for Wellness, Workplace health, Performance and Research. 

Fitness Enthusiast, Average Person

If you are trying to improve or maintain health as well as mitigate any risks for potential injury. 

Employers

The DARI Motion capture platform can perform a comprehensive biomechanical analysis in as little as five minutes allowing you to efficiently screen your entire employee population for Musculoskeletal Disorder Risk and Musculoskeletal Injury Risk

Athletes and Team Organizations

DARI can collect objective, actionable biomechanical data on entire teams in a matter of hours giving athletes and training staffs the tools to transform their motion.

Competitive Athletes

Optimize Movement, Avoid Injury, Track Progress. As soon as an athlete steps out of the capture space, DARI delivers an easy-to-read report with actionable insights, allowing coaches and trainers to get to work immediately

Research Institutions

DARI’s robust motion capture allows research to be conducted on populations that are difficult to assess with traditional systems. The capture space can support implements, such as treadmills, stairs, cycles, and chairs, items that can be critical to research-specific assessments.

Your Eyes, Feet, and the Floor Keys to Performance and Pain

If you have ever worked with us you would know how important your eyes, being barefoot, and the floor are.

If you haven’t worked with us in the past or during your initial visit you will probably be wondering: “Why is everyone barefoot, why is everyone always on the floor and why do they care about how my eyes move?”

Before we begin to answer the “Why?” we should start with the “What”; What exactly do we do? We are not in the fitness business or the physical therapy business; We are in the Optimization Business. Whether you have pain, are an athlete trying to stay healthy, you’re trying to outperform your competition, just had surgery, trying to break a record or just trying to hit your fitness goals, we are here to Optimize your human experience by achieving those goals. And guess what, your eyes, the floor, and your barefeet are important ingridients to the formula.

Your Output is only as good as the Input

Barefeet

You have about 200,000 thousand nerve endings in your foot, yes, TWO HUNDRED THOUSAND! Each of those nerve endings are called exteroceptors which provide sensory information to your brain through external stimuli. Guess what? This makes your foot one of the most nerve-rich parts of your body! Your feet are crucial in providing proprioception and communicating to the brain what the body needs to do as you walk, run, jump and play. But unfortunately, we have diminished or delayed the amount of information the brain gets by wearing cushioned shoes. Shoes are great and cool but they eliminate your foot’s ability to feel, to receive the external stimuli they need in order to properly communicate with your brain. Thus, when you come see us for whatever reason, we will address that communication problem by making you go barefoot, and sometimes, that’s all you need!

Eyes

Along with your feet your eyes are crucial in recieving information. The eyes provide a large amount of the Neurosensory input your brain needs for motor control (motor control refers to the process by which the nervous system coordinates the muscle and limbs to achieve a desired movement or set of actions). Have you ever been walking on the beach and come across a patch of shells or rocks? You probably will do two things; either walk the other way or walk as lightly as you can through them. You did that thanks to the information your eyes gave your brain. Your eyes sent the info to your brain and your brain established that there was a threat, thus going into a sympathic state (Fight or Flight. Based on the information and how your brain processed it, you either walked around (flight) or just walked through (fight).

If there is a dysfunction in your eye movement, the input will be faulty and your brain will have a harder time processing the information, affecting motor control. Your eyes are crucial to your performance. Are you the person that always misses what you’re aiming at? You might want to check how your eyes are moving and how well they are sending information to the brain.

The eyes will lead us to the next topic….

The Floor

Whats up with the floor? Above we mentioned how crucial the information your eyes send to the brain is, now Imagine if you have a fear of falling; whether its because of a previous injury or just scared to fall on your ass. If you are scared of the floor, it now becomes a threat. You will respond by going into a sympathetic state (fight or flight), and you will go into flight mode, this will hinder motorol control, which can be a reason for you falling in 1..2..3…

Hopefully you didn’t fall! Have you ever been somewhere up high and someone tells you not to look down? You look down and all of a sudden you lose your balance. Well that’s what happens when the floor is a threat. Now lets add some shoes, your feet have no awareness and can’t provide your brain with the information it needs for motor control. It sounds like you will be having a bad time walking, running, jumping, and you’re probably losing your balance all the time.

Our goal is to establish the floor as a safe place and remove it from being a threat.

Optimizing the Human Experience

The floor is no longer a threat, your feet and your eyes can now provide your brain with the information it needs through better input, we now have the desired motor control to prevent injuries, enhance performance and maybe remove pain. We have now achieved Optimization of your Human Experience.

Running: Strength Training To Improve Your Running Pt.1

Strength training for Runners

Strength Training is very overlooked and shied away from topic in the running community, as their are many myths, such as “Strength Training or Lifting Weights will make me slow”.  Strength training is a crucial component in keeping you healthy, strong, and running your best.

Runners love to run and base everything on running exercises. Here are some other famous quotes we’ve heard over the years;

“ I want to be faster let me run faster during miles”

“ let’s do fartleck instead”

” I need more endurance, let me add another mile”

And my favorite “ Weight training, won’t make me faster or let me run more”.

Can Strength Training Really Help Me?

By actually adding some form of  resistance training, whether it is maximal strength or endurance training time to fatigue will decrease, rate of force production will decrease ( this is good) and overall run time will decrease. Almost forgot to mention, impact absorption also increases which decreases the chances of injury.

One great study on this was on maximal strength training by kyvind stkren of Norway1. Their program was 24 sessions over a 8 week period, 3 days a week of 4 sets of 4 reps of half squats. At the end there was an increase of rep max of 33%, rate of force production of 26%, rate of exertion by 70%, time to exhaustion increased by 5%, but there was no correlation to vo2 max (this is normal when performing tests that do not change intensities, not a graded test).

Another study we’ll mention did a training program using both strength and endurance which showed  improvements in time to exhaustion2

In short, by adding a resistance training program that is focused on power development  and velocity it will dramatically increase a runners speed and time to exhaustion ( endurance, Lactic acid tolerance). This also lessens the increase of mass(weight) and focuses more on the neuromuscular adaptions needed for power.
