As a follow up to last Friday’s presentation on training with power, I wanted to share a workout comparison that I found interesting. In the presentation I pointed out that common intensity measurements like heartrate, perceived exertion and speed were lousy indicators of workout intensity for cycling and that power is the only direct measurement of work produced by a cyclist. Toward the end of the presentation I showed the data from a 20 minute interval that I completed outside using a PowerTap on a windy day with elevation gain net uphill to demonstrate this point.
Today I was prescribed the same workout, which consists of 90 minutes of warm up & endurance type efforts followed by the 20 minute threshold interval. This morning the weather was not good enough for me to ride outside so I chose to do the work indoors on the computrainer. After downloading the data I found it very interesting how the same workout done two different ways yields similar power data:
11-13-11 11-27-11
Normalized Power 260 257
Avg Power 254 256
Avg Heartrate 169 164
Avg Cadence 88 93
Avg Speed 18.8 22.7
Work 304lJ 307kJ
TSS (IF) 29 (.944) 28.2 (.931)
RPE 10 10
My A race is in May so periodization wise I am building base and the training volume was similar for both weeks. Without the power data there is no way for me or my coach to accurately measure the intensity of the interval and know whether I completed it correctly. Having power data assures you that you’re working correctly.
I hope Santa brings you a Power Meter for Christmas ;D
