Effective Training Data

Data from the CardioCoach can be used as the foundation for customized exercise programs that will meet your goals for each individual athlete. Important data like VO2 Max/Sub Max, Anaerobic Threshold, precise target heart-rate zones and calories burned during exercise are gathered and presented in a manner that is easy to read and interpret for both trainers and athletes. 

Easy Implementation

Adding VO2 Max testing to your training doesn’t necessarily require extreme changes to what you’re already doing. CardioCoach is created to fit in seamlessly with previously established programs. It can move from room to room and is so simple to use that any of your current trainers can perform and interpret a VO₂ Max test.

Affordable Equipment

CardioCoach comes in various models tailored to your training needs, so you only pay for what you need. Baseline models start with a one-time payment of $5,995*.

A VO2 Max Test is a measurement that reflects a person’s ability to perform sustained exercise. It is generally considered the best indicator of cardiovascular fitness and aerobic endurance. The actual measurement is “milliliters of oxygen used in one minute per kilogram of body weight.” It is suitable for a wide range of individuals, from the sedentary to elite athletes.

VO2 Max testing with CardioCoach is as easy as one, two, three…

  1. The client puts on a mask and heart rate strap. The mask is connected to the CardioCoach™ device via the VO₂ hose.
  2. The client exercises on a stationary device such as a bicycle, treadmill, or stair stepper. They gradually increase their intensity over a period of 6 to 20 minutes until the CardioCoach™ indicates that the anaerobic threshold has been detected. At this point, the client may stop exercising and begin a cool down phase.
  3. The CardioCoach™ compiles the data, analyzes the results and will print a fitness profile in a simple, insightful report where exercise zones are identified. Trainers can further customize their client’s workout by uploading the results to the CardioCoach app.

VO2 Max testing is a valuable tool for serious athletes to assess performance and evaluate training regimens. Even though extensive training can sometimes cause an athlete to reach a plateau in VO2 Max, he can still use his VO2 Max test results to make further improvements in performance. This is accomplished as he pushes to increase anaerobic threshold (AT) and maintain that threshold for longer periods of time. This enhances both endurance and cardiovascular performance.

A complete VO2 Fitness test can give trainers and clients the tools to set realistic goals and assess improvement. Studies show that previously sedentary people training at 75% of aerobic power for 30 minutes, 3 times a week over 6 months increase VO2 Max an average of 15-20%. Many people are inefficient exercisers, with no understanding of what specific heart rate, intensity or duration would best help them reach their specific goals such as fat burning, endurance training, or cardio conditioning. An initial VO2 Max test can clarify the specific target heart rates that will enable each individual to reach their fitness goals more effectively, with less fatigue and fewer injuries. Periodic retesting provides motivating feedback as the fitness program progresses.

The CardioCoach has a simple user interface with wireless connections. No training or certification is necessary. 

Self Calibrating
Adjustments for barometric pressure, temperature, and humidity are key to an accurate VO₂ measurement. The CardioCoach measures these parameters during each routine calibration cycle, then automatically compensates to standard (STPD) conditions.

Simple Service
Routine replacement of the oxygen sensor is required but can be performed on site by your own staff.

Immediate Results
CardioCoach software allows you to watch live data during the test. It also allows you to view and print results, including customized heart-rate zones, immediately after the test. 

Workout Zones
CardioCoach uses Anaerobic Threshold and VO2 Max results to define workouts zones unique to each client. These results can be uploaded to the CardioCoach app to guide your client through workouts for cardio-strengthening, endurance, weight loss or other goals custom designed by you.

Mixing chamber Technology
A mixing chamber is considered the “Gold Standard” for VO₂ Max measurements.In the past, this system has been complicated and expensive, making it only practical to train professional athletes and for use in research departments. KORR’s advancements in technology make this equipment feasible for gym owners and trainers at any level of expertise to own.

Many physiology labs use the Parvo Medics TrueOne 2400 metabolic measurement device to measure VO2 peak. This device is one of the most reliable methods of measuring oxygen consumption during exercise but is also very expensive. There are more affordable devices which also measure VO2 peak but their validity may be questionable.

PURPOSE: This study sought to determine the validity of VO2 peak measurement using the CardioCoach device compared to the Parvo Medics device. If the results are similar then use of the CardioCoach to determine an accurate measurement of VO2 peak is a viable alternative.

METHODS: VO2 peak of five young athletic individuals (aged 22.4 +/3.3 y) were tested on the Parvo Medics (Sandy, UT) and CardioCoach CO2 (KORR Medical Technologies, Salt Lake City, UT) devices. The same test protocol (1min increments) was used for both tests. Tests were separated by one week and subjects were asked to refrain from strenuous activity the day before

each test. Dependent tests were used to analyze mean differences between subjects for each device at the p2 peak of the Parvo Medics device was 39.4 +/62.4ml/kg/min while the CardioCoach was 40.5 +/65.1ml/kg/min (p>0.722).

CONCLUSION: Based on the results, there is statistical evidence to conclude that the two devices produce similar VO2 peak values, meaning that the CardioCoach CO2 is a valid method to test VO2 peak. Future studies, however, should replicate this study with more subjects to improve statistical power.
