perspiration == effectiveness?
I work out on the rowing machine twice per
week, among other things; running, stationary bike, swimming, tennis, squash. It's the best full body workout I know. I typically do 25 min., 250 calories. However, there's one odd thing - I hardly sweat! Is this a bad sign? Is the 'fitness feeling' an illusion, am I really not getting my money's worth? As opposed to the bike, where I'm drenched. Also, squash generates the most perspiration. Which seems weird, because it doesn't feel so draining as the others. -- Rich |

That sounds like fun, although I generally take the calorie readings from machines with a large grain of salt. As long as you always use the same machine (or same type of machine) it is a useful benchmark though, and you probably do burn approximately that many calories.

If the room where you use the rowing machine has an unusually low relative humidity, for example, or more airflow, then it would effect how much sweat build up you get. Playing squash in a warm, poorly ventilated, and humid room is going to make you sweat a lot, even if you don't hardly move around at all. Heck, sit in the sauna for a bit and you'll sweat buckets without even moving. If you want to measure how hard you are working get yourself a heart rate monitor. It's not perfect, but it is a heck of a lot better than trying to measure how much you sweat. Jason |

Environmental factors being equivalent, sweat is proly a better indicator of calorie burn than HR -- in essence a calorimeter, as sweat is a response to body heat, whereas HR can be stimulated in a variety of ways. The squash proly doesn't feel as draining because so many different muscles are being used, so that no one group is being fatigued, but the total heat production is very high -- environmental stuff notwithstanding. -- EA |

It's not perfect, but it is a heck of a lot better than trying to measure how much you sweat. One thing I've noticed with running in a club is how much sweating varies from runner to runner. Logic would suggest that being fitter would result in less sweating but if anything, I've noticed the reverse. It would seem that fit runners start sweating "pre-emptively" to avoid overheating This isn't awfully consistent however and I think some folk are just "early onset sweaters" whilst others are "late onset sweaters". Consequently, I think it would be hard to use sweating as a measure of how hard one is working other than to say that on an individual basis, the more you sweat, the harder you're probably working.

It would seem that fit runners start sweating "pre-emptively" to avoid overheating That would be a very inneresting study, to see if training begets sweating. Evolutionarily, profuse sweating could be quite the DISadvantage, in certain climates.

Consequently, I think it would be hard to use sweating as a measure of how hard one is working other than to say that on an individual basis, the more you sweat, the harder you're probably working. True, only a valid comparison within an individual. Still, a useful barometer, if environmental factors can be parsed out. It's interesting to try to equate caloric burns of different exercises/activities with running. I have done this extensively with some of my "proprietary calisthenics", on both biomechanical/calculational bases, AND perceptual bases, which includes the sweat factor. Not an easy thing to do, but between the two methods, it seems you can converge on a value. But, nothing like a calorimetric chamber... which, btw, are themselves difficult and expensive to use, which is why indirect calorimetry (VO2) is so popular. But unfortunately, indirect calorimetry is not useful for non-steady state non-aerobic efforts. -- EA Tim |
