Low efficiency (20%) would help but we are still talking about a FTP of 233ish which begs the question why the efficiency is so low (one hour mark). Is it even possible anyone with that low of an efficiency, an indication of fitness, capable of cranking that wattage for one hour? With n=1, NO. Four hours at that wattage…

http://www.dcrainmaker.com/product-comparison-calculator?type=power-meter#select and that's my understanding regarding "claimed error". Cannot remember which meter(s) had >2% claimed error rate but think it might have been iBike and/or PowerCal, both are not really true power meters in the traditional sense.

The law of conservation of energy states that the change in total internal energy of a system equals the added heat, minus the work performed by the system, where the symbol "d" indicates that heat (Q) and work (W) are inexact differentials. dE (energy) = dQ - dW Work is a displacement of the point of application in the…

The white paper also indicates the practical use is for "light physical activity or physical training", and the model is based on "submaximal steady state and maximal incremental bicycle ergometer (Ergoline, Bitz, Germany) exercises and real-life tasks (RLT) were carried out during two different days separated by 1-2…

Short answer is slowly built up your fitness and let your body do it's thing. All the stuff about controlling your breathing, deep breaths, through the noise, etc are taken out of context. "Ventilation is regulated in much the same manner as cardiac output. The heart increases cardiac output by increasing both stroke…

When I run the query with MFP in Strava, it returns with three groups. Two already mentioned and a third for winter cycling. Think the older group was initially created as a contest mirroring the grand tours. Winter was another offshoot. There a group here where folks converse; not sure how active now but saw some traffic…

Intensity is what you make of it and most people find it harder on a indoor trainer verses outdoor ride. See http://alex-cycle.blogspot.com.au/2009/01/turbocharged-training.html. I have a Kurt Kinetic Road Machine purchased three years ago. Given the recent price drop of smart trainer, I would have second thoughts if…

Nice. I still keep track of my resting HR but PM for everything else. Haven't tested since last September but I think my FTP is at 260ish. Screw up the zero reset the last century on the 9th so it a stab; rest of the time been indoors. The best from last year was an average of 162w, 202w NP, & IF of 0.812 over 120.3 miles…

Odd, why are you using HR when you have a power meter? It measures the work done and it's basic physics (definition of the unit of measurement) on the conversion. An average of 277 watts is roughly 1,000 Calories at 25% efficiency. 25% efficiency is also the upper range and reflect conditioning of elite athletes. HR…

Debatable, some trainer workouts are more equal than others. And, what happens to the miles when your computer messes up? Is it me or does the wattage from Zwift (Computrainer and others also at times) looks low on the magnitude of 20-30+ watts? Flat, no wind, and open road at 20mph I'm around 220-230w but I'm seeing…

If you want to use HR as a control for you training, do a Lactate Threshold Heart Rate test. You are just guessing otherwise.

Good luck. I was off for 23 years after having one of the most expensive crash in the final 100km, took out almost everything in the front end, and got a ultimatum to finish my degree. I stopped cycling and didn't get back on until three years ago mainly for May is Bike Month. I took it more seriously in 2015 and logged…

Sufferfest

For the whole week, Mon-Thu. 2 hours is the longest for now.

6+ hours on my trainer (Kurt Kinetic Road Machine) on weekdays. Longer rides on weekends when not raining, else more time on the trainer. Although they're crafted for cycling, think Rule #5 and #9 applies to a few here (http://www.velominati.com/the-rules/).

In popular culture, "Tabata training" has now come to refer to a wide variety of exercise regimens that may or may not have similar benefits to those found in Tabata's original study. Same goes with the mislabeling of interval training as High Intensity Interval Training (HIIT), abbreviated in all caps. When properly done,…

I use it as a secondary journal and as a comparison tool again other riders (cyclist from my club). All my activities are uploaded to the site; I use a different app, IpBike, and Sony Xperia Active phone as my dictated cycling computer (it has all the bells and whistles, and more, as a Garmin Edge except for the battery…

It's a luxury as much as a HRM and a GPS watch. Unlike other metrics, a PM measure your work independent of other factors such as it's too cold, a bad night's sleep, dehydration, bad head wind, steeper climb, etc. It allows one to evaluate one's training effort subjectively, train in a more structured manner, and is a…

40 minutes? LTHR test is normally @ 30 minutes but first ten minutes is to get into the groove. 20 minutes FTP in cycling is what most do, 30 minutes to get closer to the mark, and 40km TT the gold standard. I hope they get a production power meter for running soon as it has dramatically changed how cyclist train for the…

There are very few sports that can truly benefit from HIIT and running is one of them. HIIT is a regimen (routine - do this for... and that for... at this level of intensity...). It's a tool for competition that sharpen and/or peak for explosive power in the final meters. Per unit of time, HIIT does expend a large amount…

Educational :-) Think I only bonked once. Always thought there should be more signals (drop in performance, craps, etc) but remembered it was a sudden drop (25 years ago so memory kind of fuzzy; stopped regular exercise until this year). Done a few centuries this year with craps and slow crawls here and there, but didn't…

The three sources of ATP for the working muscle are the phosphagen system (blue line), non-aerobic glycolysis (red), and the aerobic system (green). The first two is anaerobic (w/o oxygen). When one talk about cardio, we are primarily referring to the aerobic system. Non-aerobic glycolysis is also part of the training…
