Effects of Initial Performance, Gross Efficiency and O2peak Characteristics on Subsequent Adaptations to Endurance Training in Competitive Cyclists [PDF]
Frontiers in Physiology, 2018 The present study investigated the effects of initial levels of cycling performance, peak oxygen uptake (O2peak) and gross efficiency (GE) on the subsequent adaptations of these variables and their relationship following high-intensity training (HIT ...

The between and within day variation in gross efficiency. [PDF]
Eur J Appl Physiol, 2010 Before the influence of divergent factors on gross efficiency (GE) [the ratio of mechanical power output (PO) to metabolic power input (PI)] can be assessed, the variation in GE between days, i.e. the test-retest reliability, and the within day variation needs to be known.

PREDICTION OF GROSS FEED EFFICIENCY IN ITALIAN HOLSTEIN FRIESIAN BULLS [PDF]
Poljoprivreda, 2015 The aim of this study was to predict gross feed efficiency of Italian Holstein Friesian bulls selected for production, functional and type traits. A total of 12,238 bulls, from the April 2015 genetic evaluation, were used.

The Use of Gross Efficiency Coefficients in Cyclists’ Endurance Tests [PDF]
Central European Journal of Sport Sciences and Medicine, 2015 The efficiency of energy conversion of aerobic metabolism to external work is of great importance to sports exercise. Despite this fact, gross efficiency (GE) is not commonly used as a parameter in the assessment of cyclists’ exercise ability.

The relationship between cadence, pedalling technique and gross efficiency in cycling. [PDF]
Eur J Appl Physiol, 2011 Technique and energy saving are two variables often considered as important for performance in cycling and related to each other. Theoretically, excellent pedalling technique should give high gross efficiency (GE). The purpose of the present study was to examine the relationship between pedalling technique and GE. 10 well-trained cyclists were measured
