Calorie burn differences from one Garmin to the next and one program to the next
Ok so I'm a bit confused here. I run a Garmin Edge 705 with HR monitor and use Training center as well as Runkeeper.com to track my riding. I know from all of the discussions since the Edge line came out (I had a 305 before the 705) that the caloric burn number they give out is WAY over inflated but let's look at my ride with my wife (she is just getting into cycling and still building up the muscles so a bit slower than I would ride solo) yesterday in Training Center: Distance 32.97 mi, ride time 2:26, avg speed 13.5 mph, 2276 cal burned, 130 bpm avg HR, 1557' ascent
Now compare those numbers to Runkeeper.com which links with the Garmin and downloads the same data file: Distance 32.85 mi, ride time 2:26, avg speed 13.42, 1584 cal burned, 127 bpm avg HR, 1458' ascent. Same ride mind you...more miles by just a tad, lower avg HR by a couple of beats per min. Obviously the biggy is the difference in calorie burn at nearly 700 cal different. I would assume the Runkeeper number is much more realistic.
Now factor in my wife's numbers...she uses a Garmin Edge 500 and comes up with similar number for the ride in terms of distance (makes sense) but for calories she gets an even lower number even on Training center...her number was like 1200 calories but her average HR was higher (we are also a similar weight) because she is farther out of shape than I am. I would think that she would have burned more calories...and apparently Garmin changed something on the device level when calculating caloric burn.
Any thoughts here?
