I ordered a second blood pressure meter to verify my old one's accuracy. My BP is a little higher with the HIIT, which surprises me. http://ift.tt/2iTzw6A

Monitoring a HIIT session of 10 seconds "all out" with full recoveries using Moxy. As expected, HR lags behind power quite a way, and the peak HR increases as the intervals progress. Also, the HR peaks become more rounded as recovery slows, suggesting my recoveries were not as complete as I'd expected. Muscle Oxygenation (SmO2) doesn't drop until well after HR has peaked, but rebounds higher than I'd have expected. Blood flow (tHb) drops during and after the interval, and takes a little longer than expected to recover. I'm quite surprised how low such a short burst can drop SmO2, and how much of a rebound occurs. So far, 30 second intervals with full recovery drops the SmO2 the lowest, down into the mid-teens, where a Tabata (or WinTab) only drops to the 40s. http://ift.tt/2yclq7b

I've added tables of OHRM accuracy for various watches I've tested. http://ift.tt/2z9L8ZM

A 3 mile time trial (18:20) to look at SmO2/tHb. You can see SmO2 drop rapidly at the start, then gradually build back up before trailing off a little. Blood flow increases for a while before reducing. Speed, power, and HR are all fairly steady. I'm not really expecting to see anything useful in the SmO2 data, as other studies have shown it fairly flat during MLSS (maximum lactate steady state) tests, but I was curious. http://ift.tt/2ySWosC

I've started to test the Vivoactive 3, and I'm publishing my testing notes as I go. http://ift.tt/2i6Bv3k

A look at a HIIT training session in Golden Cheetah with Stryd power estimate and Moxy muscle oxygen sensor. Note SmO2 dropping post interval which surprises me a little. I'm pleased with how low I was able to drop SmO2, and how consistent through to the end. Blood flow (tHb) drops during the interval, though the change is fairly small. The change in the shape of the HR shows the results of fatigue. http://ift.tt/2lg58Eg

I'm always trying to prove myself wrong. Can extreme polarization of training make more frequent running effective? http://ift.tt/2gGcJKL

My review of the excellent Topo fli-lyte 2, which is mostly unchanged from the first version. http://ift.tt/2yAyOP7

Hopefully, everything’s charged up. Testing this much gear can really delay the start of a run. http://ift.tt/2xKw2F0

My critical power shown in Golden Cheetah. It's not user friendly, but it is powerful. Running power from http://ift.tt/2vYbs3w

Another GC plot of Stryd data, this time power distribution. No surprises given my preference for LSD ;} http://ift.tt/2vYbs3w

A new running senror to test. I'm curious about it's running power estimate, and all the other data http://ift.tt/2gm2HOz

200 miles in the vaporfly and its not changed much in the last 100 miles. http://ift.tt/2ySjUmk

A minor update to my Fenix5X review around recording muscle oxygen saturation. I thought Garmin displayed the values on the web, but either it's been removed or I'm imagining things (probably the latter). You have to export the .FIT file and import it into another tool. http://ift.tt/2fU0sSl

I've added an update on the Vaporfly after 100 miles (more to come). http://ift.tt/2fzzCPs
