Hello:
I am new to this forum and I have a question concerning the relationship between power output and HR when performing 2x20 intervals. I am using a combination of HR monitoring and gear ratios rather than actual wattage measurements in order to gauge my work output which is obviously not as accurate. When I begin the interval I find it takes several minutes to bring my heart rate up to L4. Once I reach L4 (while maintaining a cadence of ~ 80rpm) I find I need to gear down as the interval progresses in order to stay in L4. If I were to stay in the gear ratio in which I began the interval there is no way I could maintain the intensity for the entire interval. However, once I have geared down, my HR stays in the correct zone but my wattage has actually dropped by the second half of the interval. Should I be performing the 20 minute interval based on perceived effort (ie use a gear ratio that I know I can maintain for the entire interval ) and pay less attention to my heart rate? (Does that make any sense?)
