Effect of Gradient on Cycling Gross Efficiency and Technique

open access: yesMedicine & Science in Sports & Exercise, 2013
The purpose of this study was to determine the effect of gradient on cycling gross efficiency and pedaling technique.Eighteen trained cyclists were tested for efficiency, index of pedal force effectiveness (IFE), distribution of power production during the pedal revolution (dead center size [DC]), and timing and level of muscle activity of eight leg ...

Gross Efficiency during Rowing Is Not Affected by Stroke Rate

open access: yesMedicine & Science in Sports & Exercise, 2009
It has been suggested that the optimal stroke rate in rowing is partly determined by the stroke-rate dependence of internal power losses. This should be reflected in a stroke-rate dependency of gross efficiency (e(gross)). The purpose of this study was to investigate if e(gross) is affected by stroke rate. A second aim was to determine whether internal

Gross Efficiency and Energy Expenditure in Kayak Ergometer Exercise

International Journal of Sports Medicine, 2012
We purposed to study energy expenditure, power output and gross efficiency during kayak ergometer exercise in 12 elite sprint kayakers. 6 males (age 24.2±4.8 years, height 180.4±4.8 cm, body mass 79.7±8.5 kg) and 6 females (age 24.3±4.5 years, height 164.5±3.9 cm, body mass 65.4±3.5 kg), performed an incremental intermittent protocol on kayak ergometer

Assessing gross efficiency and propelling efficiency in swimming

open access: yes, 2011
Determining the efficiency (and the economy) of a movement is a primary goal for those interested in understanding, and possibly improving, human locomotion and/or sport’s performance. This goal is particularly difficult to achieve in swimming where different “efficiencies” could be computed based on the partitioning of mechanical power output into its

Factors Affecting Gross Efficiency in Cycling

International Journal of Sports Medicine, 2012
There is little standardization of how to measure cycling gross efficiency (GE). Therefore, the purposes of these studies were to evaluate the effect of: i) stage duration, ii) relative exercise intensity, iii) work capacity and iv) a prior maximal incremental test on GE. Trained subjects (n=28) performed incremental tests with stage durations of 1-, 3-

Gross cycling efficiency is not altered with and without toe-clips

Journal of Sports Sciences, 2008
The aim of this study was to examine the claim that reductions of 8-18% in submaximal oxygen consumption (VO2) could be due to changing components on a Monark ergometer, from standard pedals without toe-clips or straps (flat pedals) to racing pedals of that era, which included toe-clips and straps (toe-clip pedals).

The Decline in Gross Efficiency in Relation to Cycling Time-Trial Length

International Journal of Sports Physiology and Performance, 2015
Purpose:To evaluate whether gross efficiency (GE), determined during submaximal cycling, is lower after time trials and if the magnitude of the decrease differs in relation to race distance. Secondary purposes were to study the rate of the decline in GE and whether changes in muscle-fiber recruitment could explain the decline.Methods:Cyclists completed
