PURPOSE The aim of this experiment was to establish the reproducibility of gross efficiency (GE), delta efficiency (DE), and economy (EC) during a graded cycle ergometer test in seventeen male subjects. METHODS All subjects performed three identical exercise tests at a constant pedal cadence of 80 rpm on an electrically braked cycle ergometer. Energy expenditure was estimated from measures of oxygen uptake (VO(2)) and carbon dioxide production (VCO(2)) by using stoichiometric equations… Expand
No differences in cycling efficiency between world-class and recreational cyclists.
TLDR
It is concluded that there are no differences in efficiency and economy between elite cyclists and recreational level cyclists. Expand
Inverse relationship between VO2max and economy/efficiency in world-class cyclists.
TLDR
A high CE/GE seems to compensate for a relatively low VO2max in professional cyclists. Expand
Changes in cycling efficiency during a competitive season.
TLDR
GE changes over the course of a competitive cycling season and is related to the volume and intensity of training conducted, with Riders who spent the most time training between LT and OBLA intensities better able to maintain GE. Expand
A new pedaling design: the Rotor--effects on cycling performance.
TLDR
The Rotor system might improve delta efficiency during endurance cycling, especially with trained riders, and other performance determinants VO(2max), maximal power output) do not seem to be changed compared with the conventional system. Expand

TLDR
Results show that differences do exist between trained and untrained cyclists, illustrating that training experience is a factor that warrants further investigation. Expand
Energy Expenditure Equation Choice: Effects on Cycling Efficiency and Its Reliability.
TLDR
Although changing the EE equation does not affect GE reliability, exercise scientists and coaches should be aware that different EE equations produce different GE estimates, and researchers are advised to share their raw data to allow for GE recalculation, enabling comparison between previous and future studies. Expand
Gross Efficiency and The Relationship with Maximum Oxygen Uptake in Young Elite Cyclists During the Competitive Season
TLDR
GE of young elite cyclists might not vary during the most important phase of the training season and GE was not related to V̇O2max, a lower accumulated volume and intensity of training of these cyclists may account for their lower GE in comparison to older professional cyclists. Expand
The between and within day variation in gross efficiency
TLDR
The measurement of GE during cycling at intensities approximating VT is apparently very robust, a change in GE of ~0.6% can be reliably detected, and GE does not display a circadian rhythm so long as the criteria of a steady-state VO2 and RER <1.0 are applied. Expand
EFFECT OF DURATION AND EXOGENOUS CARBOHYDRATE ON GROSS EFFICIENCY DURING CYCLING
TLDR
It is concluded that carbohydrate supplementation during 2.5 hours of cycling attenuated the decrease in GE possibly by maintaining blood glucose levels and suggests that the positive effect of carbohydrate supplementation on endurance performance may be through the maintenance of metabolic efficiency. Expand
The Reliability of Measuring Gross Efficiency During High Intensity Cycling Exercise.
TLDR
HIE acutely reduced BGE at 100%MAP may contribute to this decline in efficiency and the BE method may be a reliable and valid tool in both estimating GE during HIE and calculating aerobic and anaerobic contributions. Expand

Cycling efficiency is related to the percentage of type I muscle fibers.
TLDR
It is determined that the variability in the oxygen cost and thus the caloric expenditure of cycling at a given work rate (i.e., cycling economy) observed among highly endurance-trained cyclists is related to differences in their % Type I muscle fibers. Expand
Load and velocity of contraction influence gross and delta mechanical efficiency.
TLDR
GE is similar at all cadences when cycling at 80 and 90% VO2max, despite the significant increase in the CUC, suggesting that delta efficiency increases with increasing cadence. Expand
Efficiency of trained subjects differing in maximal oxygen uptake and type of training.
TLDR
Differences in VO2max and/or type of training have little or no causal effect on the decrease in delta efficiency with increasing work rate, which is suggested to be due to increases in metabolism not directly related to the performance of the external work. Expand
Muscular efficiency during steady-rate exercise: effects of speed and work rate.
In a comparison of traditional and theoretical exercise efficiency calculations male subjects were studied during steady-rate cycle ergometer exercises of "0," 200, 400, 600, and 800 kgm/min whileExpand
Effect of acute caloric restriction on work efficiency.
TLDR
It is concluded that, despite metabolic adaptations resulting in decreased energy expenditure at rest and during zero Watt cycling, acute caloric restriction does not alter work efficiency. Expand
Strenuous prolonged exercise elevates resting metabolic rate and causes reduced mechanical efficiency.
TLDR
O2 uptake is increased both at rest and during submaximal exercise after severe physical stress combined with sleep deprivation and food restriction, as evidenced by a increase in exercise O2 uptake. Expand
No effect of cycling experience on leg cycle ergometer efficiency.
TLDR
It is suggested that previous cycling experience was of minor importance when comparing cycle ergometer efficiency between these two groups, and the increased endurance at higher pedaling frequencies during submaximal exercise is not explained by altered muscular efficiency. Expand
Variability of aerobic performance in the laboratory and its physiologic correlates.
TLDR
The results suggest that the magnitude of physiologic responses to exercise isrelated to relative work load and that variability of physical performance is related to changes in gross mechanical efficiency. Expand
Exercise energy expenditure in extreme obesity: influence of ergometry type and weight loss.
TLDR
This study not only confirms the observation of a low mechanical efficiency of obese subjects but also demonstrates that the change is quantitatively related to the overweight. Expand
High efficiency of type I muscle fibers improves performance.
TLDR
The purpose of this study was to directly determine the extent to which differences in muscle fiber composition and efficiency influence endurance performance in competitive cyclists. Expand
