Subject: RE: D3 Newsletter - "The Extra Mile" - September 2006 amiine - 2006-09-28 8:52 AM Mike, I read your Extra Mile article “power up” and that reminded me of one of the features a power meter provides that I am not fully taking advantage of. I am referring to point 4 of the article about the kilojoules. How do you relate the kJ figure with your nutrition requirements when riding? Specifically, how do you interpret the kJ figure when conditions are extreme in order to adjust your nutrition plan for races under similar conditions? Is it as simple as taking the kJ number from a specific session, convert that into Calories and equate in the conditions of that specific session in order to determine/estimate calorie intake? (Temperature, intensity, etc) Another question about torque: If I focus on pedaling at certain cadence and power output while trying to generate a lower torque, does that mean I am working towards improving my pedaling efficiency? I figured I should ask here so all the power geeks get the benefit of your responses The amazing thing about power files and I have seen plenty of them now-from races or race simulations rides is that ALMOST all cyclists riding over 5:00 in an IM, have around 4000-4200 kj no matter the terrain, wind, or temp - of course you would need to hydrate more the hotter the temps, but this is ONE similarity we see with power - it takes the same amount of energy to go 112 miles for almost everyone. Under 5:00 and you see some higher kj readings. The way I get the kj readings is to ride a 112 mile trial at my IM IF - then I am pretty much dead on for calories during the race. Your 2nd question is a wee bit over my head - check out the power wattage forum on that. if you need the link PM me. |
