Garmin has bought Moxy Monitor. How muscle oxygen (SmO2) sensors work, what they cannot tell you, and why BSX Insight and Humon Hex closed before Garmin arrived:

Muscle oxygen sensors: SmO2 and NIRS compared
A muscle oxygen sensor straps over a working muscle and uses near-infrared light to estimate the oxygen saturation of the tissue beneath it, known as

Ever wonder what intramuscular contraction pressure and mNIRS look like during knee extensions to max task tolerance? 🦵🔦

mNIRS SmO2 on left. IMP on right. Look closely! 👀

Desktop on the left shows muscle oxygen saturation (SmO2) in the vastus lateralis from Train.Red mNIRS, showing deoxygenation during repeated knee extensions to maximal task tolerance. Desktop on right shows intramuscular pressure from the same muscle, showing peaks during each contraction, where the magnitude of the peaks tends to increase during the set until near the end where fatigue limits the contraction pressure. Experimental set-up with intramuscular pressure catheter inserted into right vastus lateralis under the mNIRS sensor.

TIL `Find()` returns the first match then stops searching.

10x speed and 40x memory improvement in one of my core package functions!

I wonder where else I can implement? 🤔

I'm glad nintendo gave us an Odyssey sequel/spirtual successor with DK Bananza. it leads me to believe theyre going to do something crazy and unexpected with the next 3D Mario, which is what i wanted over SMO2.

Combined with SmO2 resaturation rate (slope of reoxygenation during rest between each incremental stage). Tends to increase from Sept to Nov (inset), speculatively suggesting greater convective mQ̇O2? Then declining from Nov to Feb 🤔

Not sure how to reconcile the NIRS-BP & resat rate trends here yet

Interesting thread on measuring SmO2 using NIRS devices and bilateral differences.

@philipskotzke.bsky.social found that across three trials the bias between measurements in the dominant and non-dominant leg vastus lateralis (VL) at the end of a graded cycling test was -2±20% 95% LoA.

Compared to test-retest agreement SEM = ±5-9% within each leg

they did and I can't wait for it, I think it looks like an incredible spiritual successor to odyssey, but I'm hoping for the next 3D mario to be something completely new, not SMO2

Converting my data analysis app from python, to react and react native has been more challenging than I anticipated. Back end is working now, so training sessions can be loaded, curve fitting applied, metabolism assessed using raw data, and our bespoke HR and SmO2 linear methods built in now.

Participant 1RM strength would insignificantly influence SmO2 slope across workload relative to %1RM (top plot) and significantly influence intercept but not slope on abs kg load (bottom plot): Stronger people would have higher SmO2 at the same kg than less strong people. Revolutionary! 😄
m_rel <- lmer(smo2 ~ load * strength + (load | id), data = df) m_abs <- lmer(smo2 ~ load * strength + (load | id), data = df_abs) - all loads paired within participant - smo2 continuous from Train.Red normalised individual physiological range - load continuous abs (kg) or relative (%1RM) at prescribed workloads seq(0.2, 0.6, 0.2) and c(10, 15, 10) for each participant - strength continuous 1RM in kg

Sub-4 around Lake Tahoe in the books (3:50:42)! ⏱️

My Edge 1040 Power Guide prescribed a steady Tempo pace, but live Moxy SmO2 & AlphaHRV telemetry told the real story: chasing inflated targets pushed my heart rate past VT2 & tanked Performance Condition to -10.

low key mad that it definitely seems like the ideas that the super mario odyssey team had for smo2 evolved into donkey kong bananza. i wanted more smo so bad. and where’s diddy kong.

feels like drill Mario would be drilling and getting treasure and then they were like hello no make a big ape do it

Garmin sounds serious about #muscleoxygenation #mnirs. "Muscle Battery" gives me high hopes and cautious expectations 😄 What do you think?🤔

Very interested to see how they solve the hardware distribution problem, and how the model learns from repeated measurements
