TLDR
There is a wealth of information from both applied and experimental work, which, when considered together, suggests that sports performance is affected by time of day in normal entrained conditions and that the variation has at least some input from endogenous mechanisms.Abstract:
We discuss current knowledge on the description, impact, and underlying causes of circadian rhythmicity in sports performance. We argue that there is a wealth of information from both applied and experimental work, which, when considered together, suggests that sports performance is affected by time of day in normal entrained conditions and that the variation has at least some input from endogenous mechanisms. Nevertheless, precise information on the relative importance of endogenous and exogenous factors is lacking. No single study can answer both the applied and basic research questions that are relevant to this topic, but an appropriate mixture of real-world research on rhythm disturbances and tightly controlled experiments involving forced desynchronization protocols is needed. Important issues, which should be considered by any chronobiologist interested in sports and exercise, include how representative the study sample and the selected performance tests are, test-retest reliability, as well as overall design of the experiment.read more

Sleep and athletic performance: the effects of sleep loss on exercise performance, and physiological and cognitive responses to exercise.
TL;DR: The importance and prevalence of sleep in athletes is evaluated and the effects of sleep loss (restriction and deprivation) on exercise performance, and physiological and cognitive responses to exercise are summarised.
Journal ArticleDOI
Jet lag: trends and coping strategies
TL;DR: The methods, both pharmacological and behavioural, that have been used to alleviate the negative results of time-zone transitions, and the results form the rationale for advice to travellers flying in different directions and crossing several time zones.

Altered sleep–wake cycles and physical performance in athletes
Thomas Reilly,Ben Edwards +1 more
TL;DR: There are still unanswered questions about the sleep needs of athletes, the role of 'power naps' and the potential for exercise in improving the quality of sleep, and the effects on circadian rhythms are to be separated from the fatigue process.
Journal ArticleDOI
The effect of static, ballistic, and proprioceptive neuromuscular facilitation stretching on vertical jump performance.
TL;DR: In this paper, the authors compared the acute effects of different modes of stretching on vertical jump performance and concluded that PNF or static stretching should not be performed immediately prior to an explosive athletic movement.

The effect of training at a specific time of day: a review.
Hamdi Chtourou,Nizar Souissi +1 more
TL;DR: Adaptations to training are greater at the time of day at which training is regularly performed than at other times, although modifications in resting hormones concentrations could explain this time-of-day specific adaptations.

Statistical Methods For Assessing Measurement Error (Reliability) in Variables Relevant to Sports Medicine
Greg Atkinson,Alan M. Nevill +1 more
TL;DR: It is recommended that sports clinicians and researchers should cite and interpret a number of statistical methods for assessing reliability and encourage the inclusion of the LOA method, especially the exploration of heteroscedasticity that is inherent in this analysis.
Journal ArticleDOI
Design and analysis of research on sport performance enhancement.
TL;DR: Assessment of research aimed at measuring performance enhancements that affect success of individual elite athletes in competitive events found that estimates of enhancement of performance in laboratory or field tests in most previous studies may not apply to elite athletesIn competitive events.

Circadian variation in sports performance.
Greg Atkinson,Thomas Reilly +1 more
TL;DR: Although athletes show all the symptoms of ‘jet lag’ (increased fatigue, disturbed sleep and circadian rhythms), more research work is needed to identify the effects of transmeridian travel on the actual performances of elite sports competitors.

Complex interaction of the sleep-wake cycle and circadian phase modulates mood in healthy subjects.
Diane B. Boivin,Charles A. Czeisler,Derk-Jan Dijk,Jeanne F. Duffy,Simon Folkard,David Minors,Peter Totterdell,Jim Waterhouse +7 more
TL;DR: Results indicate that, in healthy young subjects, subjective mood is influenced by a complex and nonadditive interaction of circadian phase and duration of prior wakefulness, and the nature of this interaction is such that moderate changes in the timing of the sleep-wake cycle may have profound effects on subsequent mood.

A new approach for the determination of ventilatory and lactate thresholds.
B. Cheng,Harm Kuipers,A. C. Snyder,Hans A. Keizer,Asker E. Jeukendrup,Matthijs K. C. Hesselink +5 more
TL;DR: The Dmax method appears to be an objective and reliable method for threshold determination, which can be applied to various ventilatory or metabolic variables yet yield similar results and showed that breathing frequency can be used to determine VT.
