Bike fitting: finding an optimum between performance and overuse injuries prevention? Influence of saddle fore-aft position on knee joint forces
Journal Title: Journal of Science and Cycling - Year 2016, Vol 5, Issue 2
Abstract
The Union Cyclist International (UCI) regulates saddle setback - ‘ the tip of the saddle shall be a minimum of 5 cm to the rear of a vertical plane passing through the crank axis but no maximum is recommended’ - while there is no scientific rational supporting this regulation. Furthermore, the absolute value of 5 cm applies to all cyclists without accounting for cyclist’s anthropometry and, in other disciplines such as track cycling and triathlon that are not subject to this regulation, a smaller setback is often used while there is no higher prevalence of joint overuse injuries.

Effect of deceptively aggressive bike pacing on sprint-distance triathlon performance
Introduction: Whilst aggressive bike pacing has been found to impair subsequent run performance during triathlon, this strategy appears to enhance total cycle-run time over the sprint-distance format (Suriano & Bishop, 2...
Reproducibility of a Laboratory Based 1-km Wattbike Cycling Time Trial in Competitive Cyclists
The purpose of this study was to evaluate the reliability of a 1-km cycling time trial using a Wattbike cycling ergometer in competitive cyclists. Ten competitive male cyclists (mean ± SD; 63.9 ± 5.1 mL·kg-1·min-1) perfo...
Internal Mechanical Power During Cycling Using Non-Circular Versus Circular Chainrings
Introduction: Non-circular Rotor Q-Rings have been shown to increase tangential force during the pedalling downstroke compared to conventional circular chainrings1, and due to this advantage, have been proposed as a pote...
Comparison of physiological and perceptual responses to a maximal exhaustive test performed on the SRM and the Cyclus2 ergometer
Background: No cycle ergometer perfectly replicates the physiological demands and movement patterns associated with real world cycling (Abbiss et al., 2009: International Journal of Sports Medicine, 30(2), 107-112). The...
Impact of Cycling Intensity on Cycle-run Transition in Female Triathletes
PURPOSE: The purpose of the study was to determine the impact of intensity during the final km of a cycling bout on subsequent run and overall cycle-run (CR) performance. A secondary aim of the study was to examine how...
