Repeated, episodic bouts of skeletal muscle contraction undertaken frequently as structured
exercise training are a potent stimulus for physiological adaptation in many organs …

Human skeletal muscle demonstrates remarkable plasticity, adapting to numerous external
stimuli including the habitual level of contractile loading. Accordingly, muscle function and …

Circadian rhythms evolved through adaptation to daily light/dark changes in the
environment; they are believed to be regulated by the core circadian clock interlocking …

Perturbed diurnal rhythms are becoming increasingly evident as deleterious events in the
pathology of metabolic diseases. Exercise is well characterized as a crucial intervention in …

Minimal measurement error (reliability) during the collection of interval-and ratio-type data is
critically important to sports medicine research. The main components of measurement error …

Background Many variables related to sport have been shown to have circadian rhythms.
Chronotype is the expression of circadian rhythmicity in an individual, and three categories …

Excessive glucocorticoid exposure during chronic stress causes synapse loss and learning
impairment. Under normal physiological conditions, glucocorticoid activity oscillates in …

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 …

Background Whether you are a morning lark or a night owl has proven to be a key
contributor in the timing of peak athletic performance. Recent evidence suggests that …
