One could use this method to determine your MHR for cycling. There can be marked discrepancies between the estimated MHR and real life results (up to 5% of athletes can have heart rates 20 beats above or below the ESTIMATED figure). And if you are in shape, the typical decline of one beat per minute per year doesn't always hold. Warm up thoroughly (maybe 15 minutes on the flats). On a long, steady hill (doesn't have to be steep)increase effort every minute for at least 5 minutes until you can't go any faster (sitting, not standing). Then sprint for 15 seconds (it is OK to stand at this point). Stop, get off the bike (this is for safety reasons - not mandatory) and immediately check your heart rate at its maximum for a full 30 seconds - then double that number. This will give you a practical maximum heart rate in beats per minute. Similar results can be obtained on a stationary trainer. CALCULATING YOUR PERCENTAGE OF MHR : Once you have determined your MHR & RHR you could go further and do this calc. RestingHR55 - MaxHR182 = 127bpm 127 x your % that you want, say 70% = 88.90 88.90 + RestingHR55 = 144bpm. Therefore 144bmp = 70% Please correct me if I'm wrong.
