By changing the subject, the nature of the original thread might be "lost", depending on how a person's newsreader presents the thread. > When I'm through with the > elliptical machine (after about 45 minutes, with at least 30 of those > minutes being in the 115-125 bpm range) my shirt is a soaking rag. Indicating your HR tells us little. What is more important is your %maxHR. I would __not__ assume that your maxHR is 168 (220 - 52) and therefore 115-125 is 68-74% MHR. But if that is what you assume, that is not very strenuous exercise for the majority of your session. What is (%M)HR for the other 15 minutes? By the way, I am not suggesting that you exercise more strenuously. If the exercise feels strenuous at that HR, either your MHR estimate is too high, or there are other conditions that cause you to perceive strenuous exercise. At any rate, you are doing the right thing if you are "listening to your body". I am simply making the point that telling us your HR tells us little. > I fill up a small Aqua Blue water bottle before I start, and don't > drink any until after I'm about 14 minutes into my workout.

I was afraid Steve's comments might evoke this kind of undue concern. Each person sweats more or less according to his/her individual needs. Obese people tend to sweat more than "usual", even at low HRs. I would be concerned about the amount of sweat only if it is one of many symptoms that could indicate another problem. For example, if you also felt dizzy. Otherwise, there is no reason to cut back. I begin to sweat just thinking about exercise -- or so it seems. What I hope Steve meant to say is: it is unwise to increase sweating artificial, specifically by raising body heat. Excessive sweating does put extra demands on the body. For example, you lose electrolytes at a higher rate. And of course you dehydrate at a higher rate. To that end, if you do sweat a lot, you might need to replenish water at faster pace than "normal". You might also need to replenish electrolytes at a faster pace. What is "normal"? No one really knows. But there are some guidelines that experts tout. I'm not sure I remember them correctly off-hand; something like 1 pint of fluid for every hour of strenuous exercise, and consider drinking an electrolyte- enhanced fluid or otherwise replenishing electrolytes if you exercise strenuously for much more than 1 hour. One way to gauge your water needs is to weigh yourself before and after exercise. If you see a substantial change, it is due to water loss, and you should hydrate more during exercise. Of course, weigh yourself nude or in the same dry clothes. Otherwise, you are simply weighing all the water that your clothes soaked up. And during exercise, follow this simple guideline: do not wait until you are thirsty to drink. > I have to go change it to continue with any machines or stretching I > might want. Smelly sweat might be indicative of a problem. Usually clothes and sweat smell badly due to bacteria building-up. (Certain foods can also affect body odor.) I choose clothes that wick sweat away from the body.

I wear shorts that do that and they're great. I always wear a Russell all cotton t-shirt, because I don't like the look of the other type, although I'm open to change, especially if I could find them with shirt pockets. |
