Positioning of Elliptical Chainrings During Wingate Testing; A Repeated Measures Case Study
Journal Title: Journal of Science and Cycling - Year 2016, Vol 5, Issue 2
Abstract
Manufacturers of non-circular bicycle chainrings claim that use of their products can increase power output during exercise. These chainrings are generally defined as the ellipse shaped by a large diameter (major axis) and small diameter (minor axis). By adjusting the major axis-to-crankarm angle, one is effectively changing the relationship between the greatest torque arm (major axis) and position of the crankarm when the leg is extending, taking advantage of the great force production capabilities of the leg at that point.
