I would have to agree with the prior posts. When doing routine workouts my bloodsugars are pretty easy to control after reducing my basal. However, if I do strenuous activity, I see a rise at first then it quickly falls. My endo says theres not a good way to treat it. It usually doesn't last long for me and bolusing only exacerbates the low. "acidrock" mentioned something interesting, I too have noticed,when excited(public speaking, stress, excitement,etc) I get high in the upper 100's-low 200's.
