What's that? you ask. It's when your heart rate rises over time even though you are maintaining constant effort. Often due to heat build-up.
I just found out about this when I noticed something odd on my HRM graph after a session on my exercise bike.
The rapid (2 minute) up-and-down phases are due to my exercise bike's program. But between the 7 minute and 25 minute marks you can see the overall drift taking place, despite not changing the bike settings.
It was quite a relief to find out that this effect is "normal."
I'm still wondering though - does this increased heart rate mean I'm getting better cardio workout? I know it doesn't burn extra calories but I'm after health benefits more than weight loss.
