I’ve worked out a formula based on speed, weight and time to get a rough estimate of calorie burn for my cycling trips. Interestingly, it hits a bit of a plateau in the middle speed ranges, as shown below. If my calculations are correct, then, I can take it a bit easier going in without hitting a calorie penalty (or, hopefully, needing a shower). On the way home I can boot it, make up the time from the morning, and hop straight into the pool to refresh myself. Win/Win/Win/Win. 🙂
| dist (km) | 20 | ||||||
| spd(km/h) | 15 | 17 | 20 | 25 | 30 | 32 | 35 |
| Calories | 556.81 | 737 | 835.49 | 835.21 | 835.17 | 913.5 | 954.46 |
| hours | 1.33 | 1.18 | 1 | 0.8 | 0.67 | 0.63 | 0.57 |
Note that I have correlated these calculations with my heart rate monitor (which is probably using a variation of the same formula, since I worked mine out from plotting various responses from different “Calorie counting” Web sites). Bonus points if you can tell me how much I weighed when I made this graph!
My iPod does this for me.
There’s a nap for that?
Actually, I realized that I had used an older version of my formula, one that had steps, rather than a continuous function. This is what caused the totals to come out all the same. The calorie counts are close, but not bang on like my table shows. Oh well!
Yeah, some sort of proprietary software by Nike and Apple: http://www.apple.com/ipod/nike/.
I haven’t played much with it yet.
The pedometer on the iPod is pretty cool though.
