Determination of the Optimal Saddle Height for Leisure Cycling (P188)

2008

Several studies have been done on road racing cycling and triathlon to determine the optimal saddle height (LINF) in terms of efficiency. However, cycling is becoming nowadays not only a popular sport but also a mass mean of transport were comfort takes priority over efficiency. The aim of this study is to determine an optimal saddle height (LINF) to improve comfort in leisure cycling. Five male subjects (height mean=172.2 cm, std=1.34 cm; crotch height mean=81.25cm, std=0.88cm) tested 9 prototypes of the company ORBEA with 3 levels of LINF. The test consisted in one hour cycling in lab conditions and four different techniques were used to evaluate the LINF: 3-D movement analysis was used t…

Methods to determine saddle height in cycling and implications of changes in saddle height in performance and injury risk: A systematic review

2021

The objective of this systematic review was to assess the methods to determine bicycle saddle height and the effects of saddle height on cycling performance and injury risk outcomes. The key motivator of this review was to update and expand the finding reported by a previous narrative review published in 2011. The literature search included all documents from the following databases: Medline, Scopus, CINAHL, OVID and Google Scholar. Studies were screened against the Appraisal tool for Cross-sectional Studies to assess methodological quality and risk of bias. After screening the initial 29,398 articles identified, full-text screening was performed on 66 studies with 41 of these included in t…

Effect of saddle height on skin temperature measured in different days of cycling

2016

Infrared thermography can be useful to explore the effects of exercise on neuromuscular function. During cycling, it could be used to investigate the effects of saddle height on thermoregulation. The aim of this study was to examine whether different cycling postures, elicited by different knee flexion angles, could influence skin temperature. Furthermore, we also determined whether the reproducibility of thermal measurements in response to cycling differed in the body regions affected or not affected by saddle height. Sixteen cyclists participated in three tests of 45 min of cycling at their individual 50 % peak power output. Each test was performed in a different knee flexion position on …

Pinning of a kink in a nonlinear diffusive medium with a geometrical bifurcation: Theory and experiments

2004

International audience; We study the dynamics of a kink propagating in a Nagumo chain presenting a geometrical bifurcation. In the case of weak couplings, we define analytically and numerically the coupling conditions leading to the pinning of the kink at the bifurcation site. Moreover, real experiments using a nonlinear electrical lattice confirm the theoretical and numerical predictions.
