Just wondering if you could shed a little light on a HR issue.

I have been racing for 5 years, 31 years old and have an observed max HR of 193 for the last 4 years. Figure often seen especially when maxed out going for it in the sprints after attacks and counter-attacks.

For the last 3 months I have been training 150 - 165 HR, lots of base, no racing. Lab tested LT is 174hr at 4mmol.

Yesterday on a hard training ride (with a state hill climb champ) I was again running a high HR (which looks like overtraining if you take 193 as gospel), 10 beats over zones based on the previous 4 years observed max of 193, riding for 30 minutes up hill at 185 and then riding 5 mins at 191 and maxing out in a sprint for the KOM at 200?!?!

Is this the effect of all the aerobic base training? Has it unlocked an extra 7 beats? RPE for these levels seems OK as I knew I was going to be fine even at 191 and had more in the tank.

So something has changed in the last few months but what and why? I will go back to the lab and get another test this week but I’d be interested in your observations.

Thanks

Le Grimp.

Max heart rate will actually change with fitness. Generally, a very high fitness level will tend to depress max heart rate due to greater stroke volume. So if you're past your fitness peak from this season and well rested, it's conceivable that your max heart rate is higher than previously observed. Remember that max heart rate is a functional measurement due to variables such as state of training, motivation, etc.

I'd say your heart monitor was picking up interference from somewhere, perhaps from your riding partner's monitors. It's happened to me before.

Last year I had a lay off for three weeks at the end of the season, then went on a group ride. I acheived my previous max heart rate of 200 with what felt like a 90% percieved effort. This worried me so I didn't go on to find my new max !

I think that Jon is right in his theory above.
