i am an obsessive urban fixed-gear rider with my first road bike and plans to start road racing. recently i purchased a Vetta V100HR heart rate monitor/cycling computer, and have been playing around with it. i got some feedback from it yesterday that frightened me, and now i am looking for some input regarding the data, as well as the reliability of these types of units.
here goes:
on the short ride home yesterday in heavy rain and high winds my average HR while in my target zone was 157, but i hit a MAX HR of 228 (says the vetta). is this possible? i am 34 years old, so my theoratical MAX HR should be around 186. the HR monitor says i only exceeded my upper limit (172) for 33 seconds with and average HR of 198 during that time, but at some point during that time it registered 228. wouldn't i be dead or something? i race a lot of hardcore messenger style events on the East Coast, so i'm no stranger to putting out max effort, but i've only just started to do anything close to serious training. i wore the HRM to bed and got a resting HR of about 48. i haven't done a real MAX HR test yet.
can these HR monitors give false readings?
should i see a doctor?
any input appreciated....
