The acute effect of whole-body vibration on cycling peak power output
Journal Title: Journal of Science and Cycling - Year 2013, Vol 2, Issue 1
Abstract
The aim of the present study was to determine if an acute bout of whole-body vibration (WBV) prior to sprint cycling would increase peak power output. Ten male cyclists, all familiar with maximal sprint cycling exercise performed, on two separate occasions, a ten second standing sprint on a cycle ergometer. For one trial the sprint was preceded by a 2 minute WBV intervention, requiring the participant to stand on a vibrating platform that produced sinusoidal oscillations. The frequency and amplitude of the vibration was set at 26Hz and ‘high’ (approximately 2mm) respectively. For the other trial participants stood in the same position, however the platform did not vibrate (no-WBV; 0Hz and 0mm for frequency and amplitude respectively). No significant difference was recorded for peak power output between trials (1458.0 + 283.7 W versus 1506.3 + 232.5 W for WBV and no-WBV respectively, P = 0.17). The results suggest that WBV prior to maximal standing sprint cycling does not increase peak power output.

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...
Lactate dynamics of mountain bikers in a laboratory performance diagnostic
Background: The physiological demands in mountain bike marathons consist of intensive intermitted intervals. While aerobic and anaerobic parameters were found to be of importance when predicting race performance (Inoue e...
The effect of beetroot juice dosage on high intensity intermittent cycling performance
Background: Resynthesis of creatine phosphate (PCr) and intramuscular pH, which influences glycolytic rate, are dependent on skeletal muscle blood flow (Sahlin et al., 1979: Scandinavian Journal of Clinical and Laborator...
A depth camera-based system for estimating cyclist-bike projected frontal area
A major component of total resistive force in cycling is aerodynamic drag. For speeds greater than ~14 m/s aerodynamic drag accounts for approximately 90% of total resistive force (Debraux et al., 2009: International Jou...

Background: The sport of cycling time trials in Great Britain has taken place over several distance or time based formats since 1935. The format of this sport typically involves riders competing individually over several...
