Our methodology can be used by a rider to determine an optimal cadence without laboratory testing intervention: the rider will need to collect power output, heart-rate, and cadence measurements from training and racing sessions over an extended period (>6 months) ride at a range of cadences within those sessions and calculate his/her optimal cadence using the methodology described or a software tool that implements it. Power output reduces by approximately 6% for cadences 20 rpm above or below optimum. Optimal cadences are found for two riders (83 and 70 revolutions per minute, respectively) these cadences are similar to the riders’ preferred cadences (82–92 rpm and 65–75 rpm). For an individual cyclist's sessions, power output is related to cadence and the elicited heart-rate using a non-linear regression model. The purpose of this study was two-fold: (i) to show that such a cadence, which we call the optimal cadence, can be determined using power output, heart-rate, and cadence measured in the field and (ii) to describe methodology to do so. The cadence that maximises power output developed at the crank by an individual cyclist is conventionally determined using a laboratory test.
