Cadence and exercise: physiological and biomechanical determinants of optimal cadences--practical applications.
This critical review reflects the current state of cadence research during cyclical activities at different intensities. Moreover, this review aims at making suggestions in the areas of evaluation, therapy and sporting performance in the light of all the different results reported in studies. A large number of researchers have tried to determine the 'optimal' cadence from imposed, preferred or spontaneously chosen cadences in order to improve efficiency and performances. Results are sometimes conflicting and difficult to explain or interpret. The authors have studied the variations in cadences using a reduced number of parameters, without links between energetic (oxygen consumption, ventilation), biomechanical (force, electromyography) and/or perceived parameters (rating of perceived exertion). Conclusions point out that the 'optimal' cadence cannot be unique and must be associated with the objectives and individual characteristics of the subject (skills and training level, anthropometric parameters). In the area of training and reconditioning, cadences would have to be set in relation to the nature of cyclical activities and the subjects' condition.
