|If your guestimate for 5mph is correct, 4 mph would be more like 250 to 300 |calories per hour (remember you have traveled only 4/5ths as far during that |hour though so you don't save as much energy as it might seem). My rough |rule of thumb is: the drag nearly doubles for each knot increase in paddling |speed. My guestimates could be way off. The article did not quite match my wieght or speed so I had to guess. At the time I would paddle for an hour at 5mph then rest for 5 minutes or so and repeat until I had gone 20 miles or so. Two+ hours from the put it and then back. The first two hours would be a little over 5mph and then decrease to about 4.6-.8 or so at the last hour. This was/is on a lake that is generally calm except for the waves generated by wakes. Amazing how much of the chop is wake generated. The amount of effort, percieved that is, would say I was burning 500 calories or so per hour. I'm having to compare this to the what the dreadmill tells me so they are all guestimates. After three hours I'm very tired. The fourth is really dragging. Given the 500 number that meant I would burn 2000 calories or so in the four hours. One of my dreadmill workouts is to burn off 1000 calories. I can walk, run, crawl, etc, but I will burn 1000 calories. Usually it takes 65 minutes to do this "comfortably." I have done it in 58 minutes. That was not comfortable. 8-) I'm comparing the 500/hour with the dreadmill 1000/hour and the perceived effort seems to be about right. I'm comparing my breathing rate/labor from running or wallking vs this kind of paddling effort and it certainly seems to put me in the 500 calorie/hour range. But I could be wrong. I really would like to know. Does a real measurement require being hooked up to a lab machine to measure effort? Do we have any excercise specialists on the list? Later...
