How does BodyMetrix compare to DEXA, Bodpod, BIA, & Calipers?

How does BodyMetrix stack up to the rest?

Studies have taken place using ultrasound to measure fat and muscle since the 50’s. In fact, ultrasound scanning to regulate the body composition in beef cattle has been commonplace for decades.

BodyMetrix uses the same underlying science to produce accurate tissue thickness measurements. Its the most accurate portable way to validate changes to body composition available on the market.

Ultrasound was first used to measure human body composition in the 80’s. Measuring fat thickness is an accurate technique to measure body composition (%BF). The benefit of ultrasound is that you can also measure muscle thickness. BodyMetrix measurements use both fat and muscle thickness to increase accuracy.

Designing your heart rate training zone

Heart rate monitors provide users with a host of valuable functions and features but amongst the most useful are the ability to monitor your average heart rate and create training zone alerts with upper and lower limits.

Both of these features can make a significant contribution to helping optimise the training effort which ensures maximum workout effectiveness.

This introductory guide from Cartwright Fitness will help you calculate your perfect training zone or the ideal average session or lap heart rate for your workout.

The most straightforward method for calculating a training zone is to use the estimate of maximum heart rate by deducting your age, in years, from 220.

Estimate of Maximum Heart Rate = 220 – Age

Once you have identified an estimate of your maximum heart rate, you can then calculate a percentage of this number to focus the workout on calorie burning or cardiovascular aerobic development.

There are several methods for determining maximum heart rate and each method has pros and cons.

The purpose of determining your maximal heart rate is to then identify the training zone that best fits your fitness objectives:

Five Heart Rate Fitness Zones

• Zone 1: 50-60% of maximum heart rate

Light exercise. Maintains health, a get fit and active campaign and begins the process of balancing energy in and energy out equation. Also pre-conditioning or training session warm-up and cool-down.

• Zone 2: 60-70% of maximum heart rate

Weight Management. Lose weight and burn fat. Based on the premise that sustained low-intensity effort will on balance use more calories than short high-intensity exercise.

• Zone 3: 70-80% of maximum heart rate

Increase stamina and aerobic endurance. Training at this intensity will stimulate various physiological changes that will increase the aerobic capacity of the individual. Race pace for endurance events lasting longer than 1 hour.

• Zone 4: 80-90% of maximum heart rate

Maintain excellent fitness condition. Training at this intensity will develop speed endurance, physiologically build up lactate acid and develop efficient processes to remove this bi-product of muscular work. Training in this zone is especially important for competing in events that have a duration between 1 minute and 45 minutes.

• Zone 5: 90-100% of maximum heart rate

Manitain superb athletic condition for sprinting and other speed power training for explosive maximal speed training.

Improve performance in 14 days with PowerLung

Improve performance in 14 days with PowerLung

Here at Cartwright Fitness we’ve gone a bit crazy for the PowerLung and wanted to tell you why!

PowerLung can improve breathing and performance by using it for just a few minutes each day. From those with limited mobility or disability to elite athletes – it benefits all.

Breathlessness can be a real barrier for some people, it can even stop people from exercising. Consider someone who may be overweight who is told to do some exercise for health reasons but because of the weight they carry, they become out of breath before they can get much exercise done.

​Elevating Performance by Improving Mobility

​Elevating Performance by Improving Mobility

Whether you are training to become a successful athlete or trying to stay in shape and promote a healthy lifestyle, mobility is of the essence in elevating your performance and ensuring long-term health. In fact, mobility training is crucial not only for increasing the range of motion when you exercise specific movements but is also essential for joints, muscle tissue, tendons and ligaments, in promoting their health and strength.

Ultrasound was first used to measure body composition in the 80’s, yet studies and validations have taken place since the 50’s. Measuring fat thickness is an accurate technique to measure body composition. The benefit of ultrasound is that you can also measure muscle thickness too.

BodyMetrix uses fat and muscle thickness to increase accuracy. Several studies have compared the BodyMetrix to DEXA, BodPod, Hydrostatic and Bio-impedance methods.

Why use a peak flow meter

Why use a peak flow meter

One of the uses for a peak flow meter is to measure if your asthma is under control. It measures the ‘openness’ of your upper airways. The small device measures air flowing out of the lungs as you blow into it as fast and as hard as possible.

A peak flow meter can reveal narrowing of the airways well in advance of a potential asthma attack. They are used by those with moderate to severe and persistent asthma.

Peak flow meter’s can often determine:

  • When to seek more medical support
  • Effectiveness of asthma management and a treatment plan
  • When to stop or take extra medication, as directed by your Doctor
  • What triggers the asthma attack such as exercise-induced asthma

With asthma, sometimes you may feel your breathing is okay but when measured with a peak flow meter, your lung function may have decreased.

How to perform a basic home fitness test

How to perform a basic home fitness test

Finding out your level of fitness can often be difficult. Sometimes you may feel fitter. At times you may even improve an aspect of fitness such as how long it takes to run a particular distance.

Some gyms even offer VO2 tests on fitness equipment such as bikes or treadmills. This type of test is one of the most accurate tests of aerobic capacity. Unfortunately, these tests are not always available and can be expensive. Sometimes a local university can provide these services. So if it is something of interest, contact your local facility.

BodPod vs Ultrasound (BodyMetrix)

BodPod vs Ultrasound (BodyMetrix)

You may have heard of BodPod. It looks a bit like a space shuttle that measures body composition using plethysmography. Plethysmography measures changes in volume within the body using air displacement. It’s a lot like hydrostatic weighing but using air instead of water.

A metal cylinder goes into the BodPod to calibrate before a measurement, then a swim cap donned, semi-naked individual climbs inside and begins the test.

How to choose the right blood pressure cuff

How to choose the right blood pressure cuff

Upper arm blood pressure monitors use a cuff that inflates when connected to the device. Omron Cuffs come in 3 different sizes these are:

The size relates to the circumference measurement of the upper arm. The Omron cuffs work with a range of Omron upper arm monitors. If you’re unsure if the cuff you needs fits with your device contact us and we can help out.
