Device Lag

Jet lag.

INTRODUCTION Jet lag affects most air travellers crossing five or more time zones; it tends to be worse on eastward than on westward flights. METHODS AND OUTCOMES We conducted a systematic review and aimed to answer the following clinical question: What are the effects of interventions to prevent or minimise jet lag? We searched: Medline, Embase, The Cochrane Library, and other important data...

Circadian rhythm desynchronosis, jet lag, shift lag, and coping strategies.

Jet lag and shift lag have similar physiological consequences, but shift lag is a more complex problem. The most severe desynchronization may be experienced by airline personnel making transmeridian flights. Coping strategies for eastward and westward travelers and for shiftworkers are recommended, as are interventions involving melatonin.

Cyclopean flash-lag illusion

Possible physiological mechanisms to explain the flash-lag effect, in which subjects perceive a flashed item that is co-localized with a moving item as trailing behind the moving item, have been found within the retina of lower species, and in the motor pathways of humans. Here, we demonstrate flash-lag employing "second-order" moving and flashed stimuli, defined solely by their binocular-dispa...

Jet Lag in Athletes

CONTEXT Prolonged transmeridian air travel can impart a physical and emotional burden on athletes in jet lag and travel fatigue. Jet lag may negatively affect the performance of athletes. STUDY TYPE Descriptive review. EVIDENCE ACQUISITION A Medline search for articles relating to jet lag was performed (1990-present), as was a search relating to jet lag and athletes (1983-January, 2012). Th...
