I am concerned about some things that happen when I exercise. I am 42 and am average weight - certainly not obese. Whenever I do aerobic exercise, even walking, I do OK during the exercise. But about 3-4 hours afterward, I get very tired (to the point of exhaustion), and my pulse is elevated. It seems like a "minor shock" due to exercise. I have told doctors this and they do not seem to be concerned. I even told an aerobics instructor this and he said it was very strange to do OK during the exercise but have the pulse elevate several hours afterward. Does anyone else have this or know what might be going on? I do not have chest pains, just feel exhausted. And my blood pressure if good, even a little low. But I do have high cholesterol, over 240.

It is strange.


Having come close to similar symptoms .. try checking hydration levels, blood glucose and type of exercise done last time you exercised.

They are sometimes inter-dependent.

To be well hydrated you need to be drinking a min of 2 litres (0.5 gal) per day. More on hot/dry days.

If you've not tapped into fat storage during exercise and/or muscles/blood 's low on glycogen (after metabolism's revved up after exercise), pulse might go up as compensating mechanism. Ensure you've eaten (not just before).

Sometimes, type of exercise "trains" body to expect a certain type of exertion through cues, but actually end up throwing it a curve ball.

Pulse is a good indicator of how calmly body expects to deal with any situation[s] it's been coming across. Be sensitive to how high heart rates are during exercise (definitely keep from hitting your max HR @ 175 beats/min).

Other things to check are diet and medication.

This is uncharted grounds ... go towards decisions/advice that are safety/health conscious. Don't hesitate to go back to the docs.

Hope you get it sort it out.
