O050 Fatigue in teams – does team member proximity matter? Open
Introduction The impact of 24/7 operations on cognitive performance at the individual level has been well established. However, very few studies have explored the effect of fatigued individuals on team performance outcomes. Furthermore, no…

O049 Tracking team performance during the circadian low using ocular measures Open
Introduction Distributed teams operating overnight in safety-critical environments often experience declines in performance and cohesion, particularly during the circadian low. These impairments, driven by circadian disruption, pose signif…

O047 Exploring performance across 31h of wakefulness: a task switching paradigm Open
Introduction In sustained operations, managing multiple complex tasks in dynamic environments is cognitively demanding, especially under fatigue, which slows cognitive processing, impairs attention, and increases errors. This study examine…

Increasing Positive Perception of Disability Through Depictions of Animals with Disabilities Open
Across the globe, many animals with disabilities live in zoos and aquariums, yet these institutions often face difficult questions about how to share those stories with the public in a way that raises awareness and minimizes concern about …

0204 Fatigue in Teams: Could Teaming Be an Effective Fatigue Risk Management Countermeasure? Open
Introduction When working face-to-face, teams rely on nuanced behaviours to ensure effective team performance. In the operational environment teams are increasingly distributed across multiple locations and must work together effectively d…

Fasting as an intervention to alter the impact of simulated night-shift work on glucose metabolism in healthy adults: a cluster randomised controlled trial Open
Aims/hypothesis Night-shift work causes circadian misalignment and impairs glucose metabolism. We hypothesise that food intake during night shifts may contribute to this phenomenon. Methods This open-label, multi-arm, single-site, parallel…

P046 Towards defining the sleep phenotype of children with neurofibromatosis type 1 Open
Introduction Research involving drosophila highlight the role of the NF1 gene in regulating the sleep-wake cycle. Despite this, there remains limited knowledge about sleep in people who carry a mutation in the NF1 gene, also known as Neuro…

Changes in higher order cognitive function between four watch keeping schedules Open
Maritime industries utilize many different watch keeping schedules to maintain vigilance and crew safety around the clock. These schedules can be fatiguing, negatively impacting vigilant attention. This has led to the consideration of sche…

The effects of fasting compared to eating a meal or snack during simulated night shift on changes in metabolism associated with circadian misalignment: a protocol and methods paper Open
Study Objectives This protocol paper outlines the methods that will be used to examine the impact of altering meal timing on metabolism, cognitive performance, and mood during the simulated night shift. Methods Participants (male and femal…

P076 Comparing Four Different Simulated Shiftwork Schedules on Higher order Cognitive Function Open
Introduction Changes in cognitive performance during shiftwork due to fatigue and circadian misalignment are well-documented. However experimental evaluations of shiftwork schedules are often limited to basic tasks such as vigilance and at…

O033 Is Sleeping and Waking Important for the Cortisol Awakening Response? Open
Introduction The rapid rise in cortisol after waking is known as the cortisol awakening response (CAR). However, as part of its normal circadian rhythm cortisol also rises in the morning independent of awakening. If CAR is a direct respons…
View article: O067 Comparison of Sleep Quantity and Quality during Watchkeeping Schedules
O067 Comparison of Sleep Quantity and Quality during Watchkeeping Schedules Open
Watchkeeping schedules expose workers to sleep and wake opportunities which are not at biologically ideal times, thus impacting sleep quantity and quality. This study investigated the impact of different watchkeeping schedules on sleep. N=…

O004 Circadian and behavioural impacts on salivary cortisol during simulated nightshifts Open
Introduction Cortisol regulates multiple body systems and displays a distinct circadian rhythm. Nightshift disrupts this rhythm likely disturbing physiological processes regulated by cortisol. The cumulative effect of consecutive nightshif…

The effect of time on task, sleep deprivation, and time of day on simulated driving performance Open
Sleep deprivation and time of day have been shown to play a critical role in decreasing ability to sustain attention, such as when driving long distances. However, a gap in the literature exists regarding external factors, such as workload…

Study protocol for the Shifting Weight using Intermittent Fasting in night shift workers (SWIFt) study: a three-arm randomised controlled trial comparing three weight loss strategies in night shift workers with obesity Open
Introduction Shift workers are at an increased risk of developing obesity and type 2 diabetes. Eating and sleeping out of synchronisation with endogenous circadian rhythms causes weight gain, hyperglycaemia and insulin resistance. Interven…

P007 Eating in alignment with the circadian clock: A strategy to reduce the metabolic impact of nightwork Open
Nightwork disrupts circadian rhythms and impairs glucose metabolism, increasing the risk for type 2 diabetes. We investigated eliminating or reducing the amount of food consumed during simulated nightwork as a countermeasure to reduce the …

P090 The Effect of Workload, Sleep Deprivation and Time of Day on Simulated Driving Performance Open
Sustained operations expose individuals to long work periods, which deteriorates their ability to sustain attention. Biological factors, including sleep deprivation and time of day, have been shown to play a critical role in the ability to…
