Evaluation of comfort: Acceleration transmissibility of different road bikes
Journal Title: Journal of Science and Cycling - Year 2015, Vol 4, Issue 2
Abstract
Cycling training volume is very important for professional cyclists. According to Pinot and Grappe (2014), a top-10 cycling Grand Tour finisher rides ~30,000 km and 950 h during one complete season. In this condition several factors can induce muscular injuries or fatigue such as training load, number of competitions, quality of the recovery, and posture adopted on bike. One possible additional factor for increasing this risk is related to the vibration exposure encountered during cycling on cobblestones. According to the norms and guidelines used in the world of work (e.g. EN-ISO-5349-1, 2001), this vibratory exposure could theoretically only be tolerable for seven minutes (Chiementin and al., 2011; 2013), which is very low compared to the total time spent on cobblestones during a classic cycle race like Paris-Roubaix (~1.5 h). It has been shown also that settings (tyre pressure) and bike components (frame, wheels and fork) play a key role in the transmissibility of the mechanical vibrations to the cyclists’ hands and buttock (Lepine et al., 2014). Thus to reduce the vibratory dose suffered by the cyclists, it seems interesting to choose the most appropriate settings and bike components in order to prevent muscular injuries or fatigue and, potentially, to increase cycling performance.

Thresholds in ventilation, cerebral and muscle oxygenation, and muscle activity during incremental cycling exercise
Introduction: Cycle time-trial performance is a function of the highest sustainable power output. The first (VT-1) and second (VT-2) ventilatory thresholds are practical tools for coaches and athletes to set training zon...
Estimation of Handgrip Position Based on Force Measurement During Steady Pedaling
There have been many studies on pedaling skills (Bini et al., 2013) to improve cycling efficiency. Riding position of upper body as well as leg motion is very important for cycling because it has a substantial impact on...
Effect of environmental temperature on pacing during a simulated 16 km cycling time trial
Background: In cycling time trials (TT) the aim is to produce greatest average power possible for the duration of the effort; to do this an athlete must distribute their effort efficiently to ensure that they do not fati...
Acute cocoa flavanol intake affects antioxidative capacity and mediates the no- pathway in well trained athletes: Implications for exercise performance
Evidence exists that cocoa flavanol (CF) can increase nitric oxide synthesis. This promotes vasodilation and several physiological processes, such as mitochondrial respiration and biogenesis, glucose uptake and SR-Ca ha...
