Understanding Heart Rate during HILL workouts
Trying to, anyway….
Yesterday, I did 8 hill intervals on a 370 ft. long hill at 8-9% average, the last 20 ft. kicks up to 10%.or so.
This is what I’ve noticed happens to my heart rates (using a PolarHRM), even on regular hilly rides.
· 1st Interval: climbing seated, (the first one always seems to be the hardest for me): my heart rate shoots up to 168-170 (gearing: 39x21 or equivalent)
· 2nd Interval: seated again, 162-65 (same gearing)
· 3rd Interval: standing, 165 (gearing: 42x24)
· 4th Interval: seated, 155 (gearing: 39x21 or equivalent)
· 5th Interval: seated, 152 (gearing: 39x22 or equivalent)
· 6th Interval: seated: 150 (!) (gearing: 39x22 or equivalent)
· 7th Interval: seated: 152 (gearing: 39x23 or equivalent)
· 8th Interval: standing, 162-65 (final push, getting real tire now) Gearing: 42x24
I did rest in between intervals 1-11/2 minutes, tops. HR came back to 105-110 each time.
What I don’t understand is why my HR gets lower as the workout progresses, isn’t it supposed to be the opposite ?
Is this normal ? Do anybody share the same experience ?
Pls, critique

Just ride.
How long are the intervals? If it's just the 370 ft hill, your heart and the HRM probably aren't really getting up to speed. In any case, if you HR is getting slower, it's probably because your legs are getting tired and your intensity is falling off.

I don't have an HRM, but there is one built in on the stairstepper at the gym. It seems that I have to go faster and faster to get it as high. So I think that if you go harder you can get it to go higher. It's almost as if you have to be accelerating to get it to continue to rise and if you hold constant it drops a little.

As for the 1st few intervals, maybe you weren't wqarmed up yet.
As I leave to meet up with my riding group I usually pass this 3 mile slightly inclined road where what I start in the morning 14 mph seems like I'm pushing it. After the ride and heading back up the same road I can do 19 mph and pretty much have the same heart rate.

I think the bottom line is,you have to judge what your real effort is for each interval.If indeed you did increase your effort after each subsequent interval but without the appropriate increase of the heart rate,then it may actually be the need of more time for each recovery.Cause I feel that if one is fully recovered,the heart rate should increase in proportion to your work load.
