What people conveniently forget or ignore when estimating their calories, whether with MFP or MET, is that they use the energy expenditure corresponding to the high end of the intensity spectrum and that the estimates are derived from on a subset population that may not be like you. For example the calories estimate for a…

Funny, so the circulatory system dictates one's metabolic rate and it's efficiency? Contributing is a far cry to draw a conclusion based on cause and effect. HRM is like a tachometer (engine rpm gauge) in a car. It tells you how fast the pistons are rotating but does NOTHING on how fast you are going or how much fuel is…

Estimates from a heart rate monitor are not going to be any better as it measures your heart rate, period.

"Aerobic exercise (also known as cardio) is physical exercise of low to high intensity that depends primarily on the aerobic energy-generating process. Aerobic literally means "relating to, involving, or requiring free oxygen", and refers to the use of oxygen to adequately meet energy demands during exercise via aerobic…

It's too hard for most people to do and results don't necessary fit the commercial mode. There is also a misconception than one cannot build muscle from cardio, it just look different; whether that is appealing is a different matter.

Plenty of power meter options, see http://www.dcrainmaker.com/2014/09/buyers-guide2014-edition.html. See http://en.wikipedia.org/wiki/Bicycle_performance to set your own spreadsheet calculation or try http://bikecalculator.com/ (no variable setting for efficiency but still very good). If you use Strava and store ride…

Try StravaPlus, https://chrome.google.com/webstore/detail/stravaplus/dhiaggccakkgdfcadnklkbljcgicpckn?hl=en, but it's for after ride analysis. Haven't use it since I ride with IpBike which has VP but it's not the same as a real PM; good on a trainer. Waiting on Watteam and hope it comes true. Targeting xmas for real PM as…

6 more pounds to go but might tack on another 5. It's definitely more difficult to lose the last few; 4lbs in 8+ weeks while increasing my cycling mileage from 100 to 180 a week. Hoping to make it by fall (was really hoping by summer :-(). It's been difficult to stay on the same calorie deficit as the first 40lbs while…

During college I worked in the campus bike shop and we sold a lot of tire liners. They are good for large width tires (28+) but not recommended for narrower tires. One needs to pay attention to the tire pressure and placement else run the risk of pinching the inner tube (and be prepare to fight to get the tires off with…

Bikcalculator gives 19.4mph at 56.29min at 232 avg watts which is in line with the KK VP curve deviation verses outdoor speed. 746 is the estimate for calories expended (zero bike weight, clincher, bar top, & 77 deg F). You just make me feel much more comfortable with values I got from IpBike. Keep in mind I did not have…

INDOOR ride with 2x20' and 1x10' tempo if memory servers. January 23 test puts my FTP at 247 using the indoor trainer so the power meets the ride. And yes, I average 2mph faster outdoors with similar RPE. Also yes, VP is not the most accurate and likely will shift the actual FTP but it's a consistent deviation (KK…

Bad start this week but aiming for 500 this month. Goal for fall is complete a century under 6 hours, shooting for 5 (Foxy's Davis, CA). Coming back after 24 year break and took more than 10 months to get back to the shape I was in when I started the sport 29 years ago. 12 more pounds to go before hitting the pavement hard…

Both are suspect. Here is the fine print on heart rate monitor - it measures your heart rate, period. Under specific conditions, calories can be derived from HR but you have to have everything dial in (see…

Depends on the intensity. A average two hour bike ride for me is around 1600 (based on virtual power & lower than MET estimate), minus resting it's still 1000 cal. 8 hours of sleep nets me 576ish (estimate base on 0.9 MET at 168lbs). More if I'm motivate but season's still early and I'm not planning to race anytime soon…

Rule #12 - http://www.velominati.com/the-rules/

Based on weight of 170.2, the calculated calories for my March 3 indoor ride of 1:00:01 covering a distance of 18.7 miles are as follows: * MFP - 926 (16-20 mph) * MET - 973 * IpBike - 895 (derived from power output based on empirical relationship of speed to power for the Kurt Kinetic Road Machine @ 22% efficiency, 232…

Isn't Golden Cheetah marvelous? Wish I have a real power meter but the prices are still too rich. I have KK Road Machine and use VP based on their empirical formula for indoors, and IpBike VP calc for road (corrected in excel based on indoor trends to smooth out spikes and data gaps but optimization getting to be a major…

I like cycling and do about 8 hours/week covering ~140 miles with about 4k climbs, 5 days a week

Miscalculation of their customer base? Take a look at who they contracted to make the kit; it caters to a very elite crowd. Strava could have gone with someone that make less pricier kit and/or discounted it for the added advertisement but that would take away from the mystic. And yes, too rich for my blood.

Part of the error could be due to the duration component in the algorithm used to calculate calories. It doesn't know if you walk 30 min and sit for 30 min verse walk for one hour; during the one hour period, it counted the same number of steps. The two examples will give a very different results in amount of calories…

Sounds like there is a lot of confusion, please do some additional research but here is the fine print. 1. Max Heart Rate DOES NOT necessary equal to Lactate Threshold Heart Rate. LTHR is normally less than maximum heart rate but can equal to it. Assumption is max HR is approximately 110% of LTHR. 2. LTHR is assumed to be…

Wrong! If the mass of the objects are the same and measured under the same gravity pull, they weight the same. One pound of muscle occupy less displacement than one pound of fat in the same location on earth, both still weight one pound. One pound of fat just take up more space. Or, per unit displacement (volume) muscle…

Can't tell since there is no timeline, no way to judge intensity/quality of work, and no meaningful measurements to analyze, but here is food for thought: http://www.livestrong.com/article/336162-how-many-weeks-to-build-muscle-mass/ http://www.livestrong.com/article/319061-the-timeline-for-building-muscle/ You can get an…
