Using the Moxy Sensor At Elevation Reveals A LOT About Adaptation Requirements to Altitude

Moxy Stage 2 Ft Davis HammerFest

As most of you know, I am always searching for ways to use technology so that we can better understand cycling fitness and performance. I’ve been using the Moxy Muscle Oxygen Sensor since 2014, and have developed some strong ideas about how its’ use in our studio can help us understand the following:

 

·         Proper Warm-Up Procedures for maximal saturation and vasodilation.

·         Fatigue when performing intervals.

·         Glycogen Depletion and replenishment.

·         The effect of intensity on muscles before, during, and after intervals.

·         Dehydration.

·         Recovery and Optimizing the timing of caloric replenishment.

As the Moxy became more common, Garmin got on board, and allowed their smart head units to accept SmO2 and ThB from Moxy’s on to the screen via custom fields, and once on screen, this data is now being recorded in the latest .FIT files, so it allows me the chance to look at information both acutely and empirically. Having these two data points, along with Heart Rate, Wattage, Cadence, Speed, Slope,  and elevation, has really opened my mind towards just what is possible, and what isn’t.

Well, we can now add a new phenomenon to my amateur observations; what happens when a cyclist trains at low elevation, but competes at a significantly higher elevation.

On April 1st and 2nd of 2017, I traveled from my home in Dallas, TX (elevation ~430’ or 130m above Sea Level), to Ft. Davis, TX, to compete in a Stage Race known as the HammerFest. Last year, my wife and I traveled out two days early, and rode some, to try and adapt to the elevation (5050’ or 1540m) and dry air. I’ve raced and ridden out here enough to know that my performance definitely suffers, and the goal in the weeks prior to the event is to raise my Threshold as high as possible, while also trying to raise my Vo2max. It’s a tall order, but there have been years where I’ve competed well. That said, most of the time, it’s a real struggle, and I have to believe it has much to do with showing up just a day before the race, and making the first stage, my body’s introduction to strain at elevation.

Now, thanks to the Moxy, I think I have the proof.

In the weeks building up to the competition, my intervals routinely showed rising wattages, with SmO2 levels bottoming out in the 25% range, give or take. I’ve known athletes who were able to take their SmO2 values down to the teens and single digits, but they came from a power-lifting background, and tended to be on the heavier side; perfect for most Texas cycling, but not ideal for Ft. Davis.

On the morning of April 1st, however, when I performed my warmup, I was SHOCKED to see that my Moxy was reading in the  MID 50% range, as soon as the signal was picked up by my Garmin 1000. At first, I felt this was a result of the low temperature, but as I went through my warmup, I saw that SmO2 would routinely drop down to 10% during my warmup efforts, but would rebound over time to a more-expected 70% or more.
SmO2 Stage 1 Ft Davis Hammerfest

Now, the first thing to consider is that during my warmups at lower elevation, I never began an interval set until my SmO2 would rebound to AT LEAST 85%, and as high as 92%. Furthermore, it takes me about 30-35 minutes to get my ThB values up to about 12.40. When I’m at both of those numbers, or close to them, I know I’m vasodilated, that my core temperature has risen, and my legs, at least (I measure at the Left lateralis), are ready for any efforts I throw at them.

On this morning, however, SmO2 never went above 79%, ThB never surpassed 12.34, and again, as soon as I put any real effort in to my surges, or the climbs, SmO2 dropped to between 8 and 15%, and ThB never changed.

Something was seriously off.
SmO2 Stage 1 Ft Davis Hammerfest Image 2

I finished the first stage, a Point-to-Point effort that climbed Mt. Locke, with three major climbs that finished at 6790’ (2070m), and was REALLY disappointed in my results. My watts were down, my cadence was low, I felt heavy and it felt like my legs were dead. As soon as the effort ended and I began to recover, my legs began to REALLY HURT, like I had just undergone a SEVERE resistance training protocol, with multiple sets of squats at high loads.

Disappointed as I was, I waited for my wife, who was also a bit disappointed in her performance, and we rode down together, to eat, recover, and prepare for the next stage, to be held that afternoon. Ironically, the physiological results of that stage were completely different, with an warmed-up average SmO2 in the 85% range, and a range-under-stress in the 30-45% range, which is MUCH more typical of my values during hard efforts. Furthermore, my ThB basically maxed at a stable at ~12.49, and the effort itself showed little change, around 12.00 or thereabouts. It did drop to 11.80-ish toward the end of the stage, but overall, my muscles “Felt” better, and I felt like I could challenge in the race. Now, it didn’t end up that way, but results aside, it’s the physiology that we’re studying in this post.

I’ll attach the files to the blog post if possible, and if not, I’ll try to set them up for download on Google Drive or something like that, for people to study independently, since, remember, I’m not a Scientist. I’m a hack.

So, what’s the lesson to be drawn from this? Without the Moxy, I never would have known just HOW IMPORTANT adaptation to elevation is for a cyclist, or any athlete’s, performance. During my first stage, I basically raced myself in to a deep state of muscle strain, and ended up sore for days afterward. Ironically, had I gone out on the Friday before the race, and actually performed some intervals of similar strain, I would have basically gotten through that penalty phase of adaptation, and would have been better prepared for the efforts at elevation on Stage 1. Who knows – I might have actually had an even better physiology for the 2nd stage, and would have been completely prepared for the third stage that was going to be held the next day. Sadly, a final winter rainstorm blew through the Davis Mountains overnight, and my wife and I both decided to skip a rainy, sleet-covered, 26 degree race with snow above 6000’ (1830m), and winds above 20mph. We’re both too old and cautious to try racing in those liminal conditions, especially when we know there’s really no financial reward to speak of, just a possible great story to be told from the ER.

The Moxy Monitor remains one of my most crucial elements for training and competition. Without it, I’m left guessing as to how ready my body is for work. I will definitely call off a training session if I see numbers that are ‘off’, and I also work hard, as a coach and as an athlete, to provide consistent, safe, effective protocols for warmup, hydration, and recovery.

Listening to your body is one thing; actually seeing it perform via wattage, heart rate, SmO2 and ThB, provides a holistic approach that is incomparable. I cannot WAIT to go back to elevation and ride – only this time, I’ll make sure I have an extra day squeezed in to actually perform some ‘elevation adaptation’ intervals, that will leave me more prepared to take on the slopes and loads required to achieve my best.

Using Moxy to Determine Whether You're Fresh or Fatigued

Last Tuesday, one of my clients came to the studio for a class, and opened our conversation with “Man, I had a killer workout on Monday. I hope I’m ready for this.” We began to talk, and it was obvious that he was fatigued, both mentally and physically from the previous day’s effort.

Now, this cyclist is a top-tier mountain biker, who has properly allowed himself some “Down” time, to enjoy other pursuits. When he was on-form earlier in the year, he was literally unstoppable. He only got FASTER as the fall season progressed, and it was exciting to follow. But let’s face it - getting a power meter on a mountain bike is a chore, and honestly, I don’t like all of the options that are out there right now. It’s expensive, and when people have to choose between an expensive power meter, and 4 months of coaching or more, well, the bikes are expensive enough already. Furthermore, given the stochastic, punchy nature of Texas mountain biking, I often wonder if a 1hz reading from an MTB power meter is adequate to capture the nuances and accelerations that are necessary to properly analyze a ride.

But sometimes - Physics just doesn’t correlate with Physiology. While the computer or the prediction algorithm says you “Can” do something, it doesn’t account for all the things that may interfere, like sleep rhythms, recovery from a previous workout, hydration status, all of it. That’s where the Moxy Monitor comes in.

I honestly should be using this device more, but knowing how to use it does require a bit more attention to and knowledge of “what’s going on”. But with this conversation up, I decided to take a look at Randy’s SmO2 values, and try to help him do what was best with the time he was spending at the studio.

SmO2 image 1
Now, we have to review a bit, but here’s the summary:



SmO2 values will tend to hit ‘Floors’ which align with Lactate Deflection Points 1 and 2, when properly placed on a client’s Left Lateralis. MOST of the time, we’ll see cyclists hit a “Max Active Saturation Point”, of about 85-90%, and MOST of the time, LT1 will correspond with about 40-45% SmO2, and LT2 will correspond with about 25-30% SmO2. If you get down in to the teens, or single digits, theoretically, you’re nearing necropsy.


But it was immediately obvious that something was ‘off’. Nothing about Randy’s values were normal. I checked the position of the monitor, but it was good. There was no light pollution, either. His SmO2 during intervals that were supposed to be in the Vo2 range of intensity, were wayyy too low; like near 10%. When his recoveries between intervals occurred, he hit the regular ‘max’ 80% saturation around the first two efforts, but for the entire second half of the workout, his ‘recovery’ SmO2 never cracked 65%, and his interval minimums dropped down TOO low at first, and then, again, never really recovered. Here’s a better look at the chart.

SmO2 Image 2

Here it is with power added in…

SmO2 image 3

The translation, for me as a coach? THIS GUY WAS KNACKERED! THIS GUY WAS EXHAUSTED. We were lowering his intensity well below his Critical Power early and often, he wasn’t keeping up with load, and his SmO2 minimums were STILL down in the 20% range. The recoveries never rose up much past 55%. His range was diminished, his power down significantly. He had no business attempting a hard interval set like that.

Now, let’s fast-forward to this morning. It’s been two days; he had a massage and slept a good chunk of the day after the massage (some massages are actually therapeutic workouts, and the relaxation is done AFTER the therapy). He got nine hours of sleep, was hydrated, rested, recovered, and caloried up.

Here’s his chart from today…

SmO2 Image 4

It’s a little bit harder to see, but the results were MUCH, MUCH better. Maximum SmO2 was up above 90%. Minimum SmO2 actually never went below about 40%. WE RAISED HIS CP to try and get one specific area of the intervals to sort of ‘sit’ around 50%, and it never really dropped below about 58%. It was a complete reversal of fortune. He worked hard, left with great confidence, and honestly, we probably could have gone a bit harder, though I didn’t want to try that too much, and instead focus on the success of the day, and grow it from that point.

SmO2 via the Moxy Monitor allows you to see a workout from the INSIDE-OUT, and allows you to train via your Physiology, and not just your Physics. You’re not ‘on-form’ every day. Things happen. Diets fail. Work creates stress. Maybe the music isn’t just right. Maybe it’s the holidays or EOY junk. But it helps to have a place to go where you can get a great workout that’s JUST RIGHT for YOU, and YOU only. Matching the watts to the load is just part of the story. Moxy helps you accomplish that at Cycling Center Dallas. Come visit and we’ll show you how.

Pacing Yourself For the Critical Power Tests

Power Testing is an important and exciting week! 
15 - 1

This week, we are going to determine just how effective this last block of training really was. If you are new, this a chance to establish a Critical Power and Anaerobic Capacity baseline.  You will be performing a three minute, eight minute, and thirteen minute test over two separate days. On Monday and Tuesday, we will be performing the 13 minute critical power test, and on Wednesday and Thursday, we will be performing the, eight minute and three minute tests. The goal here is to make sure that the tests are performed as hard as you possibly can perform them. You are trying to generate as much power as possible over those periods of time. These will be performed on a 2% slope, and they will be self – paced.   This is what you will see on your screen during the tests.

Thirteen Minute Critical Power Display v2
 

If you have never done power testing before -   Getting a power testing session under your belt  is especially important for you as we will finally be able to get your accurate Critical Power (CP), and find out where you are performance-wise, so we can measure your progress going forward. We will walk you through it and explain everything.   Your goal is to get the experience of your first power testing session and practice pacing, smoothness and using your gears and cadence to generate power over the duration you are testing.

For those who have tested before- this is a chance to try and beat previous records and measure progress. 

Pacing Strategies. We experimented with different ways to attempt to get the highest average power. In the past I have advocated that you start a little bit easier, and should try finish strong.

The goal for these tests will be to maintain an even power out. I will be giving you each a goal, based on your numbers during last week’s 3 and 8 minute Pre-Test intervals, and other data from the PerfPro analyzer software. You will attempt to find a power output you can maintain without having to slow down for most of the test interval.  The graph will look flat for a longer period of time.  In the last 90 seconds, you will start to push it.  Your power should continue to ramp up during this time until the end of the effort, when you should feel like you are unable to go much harder. Again - LEAVE WITH NOTHING LEFT!!!

Here is an image to show you what I mean… Pay attention to the Red Line. This is an Exponentially Weighted Moving Average, and it shows you your "Real Time" metabolic effort in watts.
Rising Intensity Version 2 on 13 minute test

Focus this week on maintaining a STEADY POWER OUTPUT for most of the test, following the wattage goal set for you by Coach Wharton. Then, with roughly 90 seconds to go, up the cadence, up the power, and shift to get as much out of your system as possible! It’s literally “CRITICAL” that you do so! It is, after all, a “Critical Power” test!

We have to get EVERY KILOJOULE of energy out of you, in order to get a good value. The more information we get, the better we can gauge progress, and capacity. We want your weekend rides to be more enjoyable, and will do everything we can to help you continue to improve your fitness and cycling knowledge, through the studio, software, and testing.

Here are some cool things we will know about you as a cyclist at the end of your power testing session.

·         Your Critical Power Number (CP, or FTP) – This is the number on your display. It is individual to you and determines how much load you get during your workout. 

·         Your Power Duration Curve -  This will reveal to us an accurate estimate of how much power you can produce during different durations.  For example, how much power you produce if you were to go as hard as you can for 2 minutes, or 4 minutes, or 10 minutes, or 50 minutes, without actually having to do a max effort for that duration. 

·         Your W prime  - This gives the coaches at CCD a better idea of what your capacity is to do shorter, harder intervals above CP, and recover from them.

I would wish you Good Luck, but you don’t need it!

You have
  • SKILL...
  • KNOWLEDGE... and
  • GOALS to GUIDE YOU!

See you at the studio!

 

PS – Be fed, hydrated, rested, and lightly salted before class. Hydration makes a HUGE difference!!
