TL;DR: It is suggested that performance was improved in the evening, and it was accompanied by an improved hormonal and metabolic milieu.
Abstract: The aim of this study was to determine the effect of time of day on performance, pacing, and hormonal and metabolic responses during a 1000-m cycling time-trial. Nine male, recreational cyclists visited the laboratory four times. During the 1st visit the participants performed an incremental test and during the 2nd visit they performed a 1000-m cycling familiarization trial. On the 3rd and 4th visits, the participants performed a 1000-m TT at either 8 am or 6 pm, in randomized, repeated-measures, crossover design. The time to complete the time trial was lower in the evening than in the morning (88.2±8.7 versus 94.7±10.9 s, respectively, p 0.05), but the norepinephrine response to the exercise was increased in the morning (+46%, p 0.05). Our findings suggest that performance was improved in the evening, and it was accompanied by an improved hormonal and metabolic milieu.

TL;DR: This paper derives the second order biases of the maximum likelihood estimators and uses them to define bias-adjusted estimators as an alternative to the two analytically bias-corrected estimators discussed and considers a bias correction mechanism based on the parametric bootstrap.
