Sorry to hear about the sickness. Heal up and get well - that needs to be the first priority. Illness is a stressor, and drugs can be too - the higher RHR might show that your body's already slightly stressed. (Your RHR is really 46, and not 146, right?) Maffetone says that if you're taking regular medication you should knock another 10 bpm off of the 180 minus number for the high end of your MAF range, so, in that case the MAF range would be 180-age-20 to 180-age-10. Although your medication might be only short term, you might want to keep your workouts at a 124 to 134 range while you're recovering and on the medication. That could help prevent excess stress from setting you back in both your recovery and your future running. You might find that you get more out of your 12 week MAF session by slowing down even more (or even just walking), than you would by running at HRs that are too challenging for your body while its healing. Best wishes for a speedy recovery.
GMoney. Yes RHR is 46 avg. made the change. Funny thing is I Feel Awesome. I do not feel stressed and my legs feel very fresh. The contact dermatitis has not affected my well being other then the drugs affecting my HR I believe. I have slowed down my pace to stay in the MAF range, but you are saying to go even slowre to bring myself way below MAF due to the stress. I guess I dont feel the stress but My HR feels it. Makes sense. UGGH not easy going slow. Thanks,
