Power Measurement: Plots

---

When one plots one set of measurement values verses another, what do the plots tell us? The Cadence stayed in a reasonable range. Could the rider have shifted gears more, keeping the Cadence in a narrower range? Would a lower Cadence be better for a time-trial? Cadence verses Speed during a short, flat time trial. Could the wide the Heart Rate range be due to varying power within a narrow Cadence range? Does the wide range in Heart Rate say that the rider's effort level could have been higher? Cadence verses Heart Rate during a short, flat time trial. This confirms that there was a wide range of power. Cadence verses Power during a short, flat time trial. © 2002 Tom Compton
