Abstract Sleep deprivation is common among university students, and has been associated with poor academic performance and physical dysfunction. However, current literature has a narrow focus in regard to domains tested, this study aimed to investigate the effects of research paper on effects of sleep deprivation night of sleep deprivation on cognitive and physical performance in students.

Participants were randomized into two conditions: The outcomes were cognitive: No significant differences were found in other variables.

Reaction time and vascular response to exercise were significantly affected by sleep deprivation in university students, whilst other cognitive and cardiopulmonary measures showed no significant changes. These findings indicate that acute sleep deprivation can have an impact on physical but not cognitive ability in young healthy university students. Further research is needed to identify mechanisms of change and the impact of longer term sleep deprivation in this population.

Student, Acute sleep deprivation, Reaction time, Cognitive, Submaximal exercise Introduction Sleep research paper on effects of sleep deprivation is common amongst university students research paper on effects of sleep deprivation live in a culture that promotes reduced sleep, due to the burden of academic work and social pursuits.

The reasons for poor sleep hygiene include alcohol and caffeine intake, stimulants, and technology, which prevent students achieving sufficient sleep time and quality [ 1 ]. An average of 5.

While many studies have investigated the effects of acute sleep deprivation, few focus on university students, despite the prevalence and impact of sleep deprivation in this population [ 45 ]. Such studies often have a narrow focus on disease states, limiting their ability to provide a holistic assessment of physical, emotional and cognitive wellbeing [ 4 — 6 ].

Sleep deprivation: Impact on cognitive performance

Moreover, students rate sleep problems second only to stress in relation to negative impact on academic performance [ 7 ]. The effect of acute sleep deprivation on physical performance has been well documented with negligible effects on intense periods of exercise, whilst endurance task performance suffers due to decreased motivation [ 89 ]. The effect of sleep deprivation on cognitive performance has also been documented previously with a correlation between sleep quality and grade point average in first year university students [ 10 ].

Moreover, sleep deprivation has been shown to have a detrimental effect on certain aspects of working memory, such as filtering efficiency, whilst Stroop test scores show degradation; however, this has been evidenced to be due to deficits in reaction time rather than processing skills [ 511 — 17 ].

Taken together, these data suggest that sleep deprivation may have a limited effect on cognitive ability in university students.

Materials and methods Study design, participants, and recruitment This was a randomized, controlled crossover study, which took place from June to September 2015.

Participants were recruited via research paper on effects of sleep deprivation approach research paper on effects of sleep deprivation posters on campus, social media, and a National Heart and Lung Institute newsletter.


Participants were told that the study involved testing parameters following sleep deprivation, but no information was given regarding the anticipated results.

Twenty-four hours prior to the morning assessment, participants were instructed to refrain from consuming alcohol and caffeinated drinks as well as abstaining from exercise, smoking, and nicotine patches.

This form was checked the following morning. More than two unexplained missed form completions resulted in disqualification from the study.

Effects of sleep deprivation on cognitive and physical performance in university students

The crossover condition and assessment were undertaken within 3—12 days of one another. Testing occurred between 09: The outcome was to measure the change, if research paper on effects of sleep deprivation, which occurred between the cognitive and physical performance of participants undergoing sleep deprivation.

Before testing began, height and weight were recorded and participants were asked to fill out a fitness questionnaire. The results of this questionnaire and participant sex were used to estimate the appropriate Monark Ergomedic 828e resistance for each participant, male: All participants were provided with standardized descriptions of tests and given the opportunity to habituate with procedures.

It involved repeating a random sequence of colors and sounds. As each level progressed, another random color-sound combination was added to the previous sequence. This test was repeated three times. Standard stroop charts were used: Research paper on effects of sleep deprivation versions of each test were created, so that no participant used the same chart twice. Time taken to complete each chart and the number of mistakes were recorded providing a measure of selective attention, automatic responses, inhibition, and control of executive functions [ 20 — 22 ].

Physical function tests Participants performed two concordant volume-time spirometry traces, in adherence to standard guidelines [ 23 ].

Three electrocardiogram ECG electrodes were attached, and non-invasive blood pressure BP measurements and rating of perceived exertion RPE were also recorded throughout the exercise test Fig.

Measurement of RPE has repeatedly been shown to have a strong correlation with the intensity of exercise being performed, independently from other factors [ 24 — 26 ].
