Moxy and Training Peaks: Putting The Athlete First

Posted by Roger Schmitz on Thu, May 18, 2017 @ 11:05 AM


Moxy and Training Peaks

For the past few years, leading endurance coaches and serious athletes have integrated Moxy’s Oxygen and Hemoglobin data into warm up, training, recovery and racing protocols with tremendous results.  Realizing the value of Moxy data, these forward thinking men and women often created their own training workarounds whether engaging in-house or online.  

I am extremely excited to officially announce the release of support for Moxy data in Training Peaks and WKO4+ software.  This integration allows athletes and trainers to seamlessly share muscle oxygen data using an industry leading training platform.

This development is the next step in our strategy of expanding the availability of critical and accurate physiological data to an ever expanding base of users.  Since our founding, we’ve taken the position that the Moxy data belongs to the athlete and should be leveraged in ways that are most effective for the athlete and by extension their coach.

Denis Šketako: A Practical Success Story

Posted by Roger Schmitz on Wed, Feb 24, 2016 @ 08:02 AM

Denis Šketako is a Slovenian triathlete that Moxy has recently begun sponsoring. He has been using Moxy with his trainer, Sašo Rupnik, for the past two years. Here is a short email interview with Denis that tells us a little bit more about him and how Moxy fits into his training.

Denis also made a video that shows how he uses Moxy, which you can check out here.  

1. How did you get interested in the sport of Triathlon, and at what distances do you compete?

I have been training for basketball at local club for 14 years, but I couldn’t see the opportunity for being a professional athlete in that environment, so I decided to find new challenges. Working as a lifeguard for a couple of years, I learned to swim pretty well. I also started with some recreational cycling. One day, the word “Ironman” randomly came to my attention, and I just couldn’t get it out of my mind. I got beaten by the curiosity and decided to give it a go. In 2011, I finished my first Ironman at the age of 21 in 10h 20min, and last year I finished it in 8h 27min.

There are many variations of Triathlon competitions, depending on the length of each discipline. I find my best performance at long distances, i.e. a full Ironman: 3.8 km swim + 180 km bike + 42 km run. To prepare for these races, I sometimes also compete in a half-distance Ironman called Ironman 70.3.

Understanding the Quality of Muscle Oxygen Metrics

Posted by Roger Schmitz on Sat, Feb 13, 2016 @ 09:02 AM

Moxy was the first muscle oxygen monitor developed specifically for athletes. Originally conceived as a possible solution for medical applications like Acute Compartment Syndrome, Peripheral Arterial Disease and Heart Failure, it has been on the market for over two years supporting trainers and athletes globally in their quest to improve sports performance. We’re starting to see competitive devices enter the market; a welcome sign of the market recognizing the usefulness of the technology for athletes. However, it does start to bring up questions about differences between these devices and the quality of their respective muscle oxygen metrics.

Reflection on the National Strength and Conditioning Association Coaches Conference

Posted by Roger Schmitz on Mon, Jan 25, 2016 @ 10:01 AM

Earlier in January, we attended the National Strength and Conditioning Association Coaches Conference in San Antonio, Texas. Using NIRS for assessing the physiologic limiter and guiding the training of endurance athletes is becoming more broadly accepted; using NIRS for Strength and Conditioning Training is less established, but perhaps represents an even larger opportunity for the technology.

Endurance trainers and athletes are used to employing physiologic information like heart rate, blood lactate and VO2 to guide their training. However, these types of physiologic information have not typically provided useful information for S&C training, either because of the time lag between performance and measurement or because of limitations on the practicality of field use of the measurement.

Researchers and S&C trainers are now finding that NIRS provides useful information for guiding training, and that Moxy is a practical device to use in field testing. We’ve seen several applications starting to develop in this space. These include the following:

The Moxy Blog: Our Values and the New Year

Posted by Roger Schmitz on Wed, Jan 6, 2016 @ 11:01 AM

As we begin a new year, we’ve decided to start posting blogs on a regular basis. In our blogs, we’ll be sharing information on topics that are a bit more in-depth and have longer-term relevance than typical newsletter material. We’ll also be covering topics that might not be as directly related to interpreting data like we would cover within our Moxy Webinar Series or on the Developer & Partner Forums.

In this post, I’d like to share a little bit about our company values. Our core group is made up of engineers and exercise scientists. We are on the geeky side in our passion for advancing the science of Near Infrared Spectroscopy (NIRS), both from a measurement perspective and from a practical applications perspective. We tend to be careful about not making claims that we can’t support with evidence. We tend to think very critically about the evidence for both new and old ideas. We try lots of ideas and see which ones hold up and which ones don’t. This isn’t to say that we don’t make mistakes or that we’ve got it all figured out. Sometimes our passion and enthusiasm get ahead of our science, but our critical thinking attitude tends to get us back on track.

How Garmin’s Connect IQ System Benefits Moxy

Posted by Roger Schmitz on Fri, Sep 26, 2014 @ 13:09 PM

Garmin’s recent Connect IQ announcement is great news for Moxy. It represents another big step forward for making muscle oxygen data widely available for mainstream fitness applications. Connect IQ is supportive of our efforts to make sure Moxy data is always portable and easily accessible so our customers can input it into whatever fitness tracking and analysis applications they want.

“Relative” vs "Absolute" Muscle Oxygenation Measurement: What’s the Difference?

Posted by Roger Schmitz on Wed, Sep 24, 2014 @ 07:09 AM


One of the differentiating factors between Moxy and many of the other Near Infrared Spectroscopy (NIRS) devices on the market (both athletic and medical markets) is that Moxy measures SmO2 on an absolute scale from 0% to 100%. Many other devices can provide an indication of whether oxygenation goes up or down, but they provide no information about where the oxygenation is on the range between fully saturated and fully desaturated.

Training Intensity Zones: Muscle Oxygen and the Limiting System

In this post, I want to go beyond simply determining training intensity zones to determining what factor is limiting the performance intensity of the athlete.
