Abstract

Purpose

The aim of this study was to determine the effect of one night's sleep deprivation on anaerobic performance and Reaction time of subjects in the morning of the following day.

Methods

Eighteen male college student athletes were studied twice in a balanced, randomized design. Subjects were measured for peak power, mean power and Reaction time.

Results

The performance showed no significant difference in both tests of anaerobic power (peak power, mean power) over the sleep deprivation period ( P= 0.3; P= 0.4 respectively), but reaction time differed significantly from baseline ( P=0.003). Results support the hypothesis that sleep serves a function of cognitive restitution, particularly in the maintenance of attentional mechanisms. In the light of the above considerations.

Conclusions

It was concluded that short-term sleep deprivation is not effective on anaerobic performance, but adversely affects cognitive function such as Reaction Time.

Effects of one night's sleep deprivation on anaerobic performance the following day.

Damien Davenne, Jacques Larue, Susan Gauthier … (2003)

The purpose of this study was to determine the effect of one night's sleep deprivation on anaerobic performance in the morning and afternoon of the following day. Thirteen healthy males were studied twice in a balanced, randomized design. The experiment consisted of two conditions 1 week apart. In the sleep deprivation condition (SDN) subjects remained awake overnight and in the control condition (reference night, RN) the same subjects slept at home, retiring between 2230 and 2330 hours, as decided individually, and rising at 0500 hours. In both conditions, activity, sleep and diet were monitored by actimetry and daily activity and dietary diaries. Physical performance testing was carried out at 0600 hours and at 1800 hours after the one night of sleep and the one night of sleep deprivation. At each test occasion, subjects were measured for maximal power ( P(max)), peak power ( P(peak)) and mean power ( P(mean)). Blood lactate concentrations were measured at rest, at the end of the force-velocity ( F- V) test, just before and just after the Wingate test and again 5 min later. Oral temperatures were measured every 2 h. In both conditions, the results showed a circadian rhythm in temperature. Analysis of variance revealed a significant (sleep x time of day of test) interaction effect on P(peak), P(mean) and P(max). These variables improved significantly from morning to afternoon after RN and SDN. The reference night was followed by a greater improvement than the SDN. Up to 24 h of waking, anaerobic power variables were not affected; however, they were impaired after 36 h without sleep. Analysis of variance revealed that blood lactate concentrations were unaffected by sleep loss, by time of day of testing or by the interaction of the two. In conclusion, sleep deprivation reduced the difference between morning and afternoon in anaerobic power variables. Anaerobic performances were unaffected after 24 h of wakefulness but were impaired after 36 h without sleep.

The effects of 53 hours of sleep deprivation on moral judgment.

William D.S. Killgore, Desiree B Killgore, Lisa Day … (2007)

Functional neuroimaging studies suggest a prominent role for the medial prefrontal cortex in the formation of moral judgments. Activity in this region has also been shown to decline significantly during sleep loss. We therefore examined the effects of 2 nights of sleep deprivation on several aspects of moral judgment. Participants made judgments about the "appropriateness" of various courses of action in response to 3 types of moral dilemmas at rested baseline and again following 53 hours of continuous wakefulness. In-residence sleep laboratory at the Walter Reed Army Institute of Research. Twenty-six healthy adults (21 men, 5 women). N/A. Compared to baseline, sleep deprivation resulted in significantly longer response latencies (suggesting greater difficulty deciding upon a course of action) only for Moral Personal (i.e., emotionally evocative) dilemmas, whereas response times to Moral Impersonal (less emotionally evocative) and Non Moral dilemmas did not change significantly with sleep loss. The effect of sleep deprivation on the willingness to agree with solutions that violate personally held moral beliefs was moderated by the level of emotional intelligence, as measured by the Bar-On EQ-i. Persons high in emotional intelligence were less susceptible to changes in moral judgments as a function of sleep loss. These findings suggest that sleep deprivation impairs the ability to integrate emotion and cognition to guide moral judgments, although susceptibility to the effects of sleep loss on this ability is moderated by the level of emotional intelligence.

Diurnal variation in temperature, mental and physical performance, and tasks specifically related to football (soccer).

Jim Waterhouse, Thomas Reilly, Ben Edwards … (2006)

Football (soccer) training and matches are scheduled at different times throughout the day. Association football involves a variety of fitness components as well as psychomotor and game-related cognitive skills. The purpose of the present research, consisting of two separate studies, was to determine whether game-related skills varied with time of day in phase with global markers of both performance and the body clock. In the first study, eight diurnally active male association football players (19.1+/-1.9 yrs of age; mean+/-SD) with 10.8+/-2.1 yrs playing experience participated. Measurements were made on different days at 08:00, 12:00, 16:00, and 20:00 h in a counterbalanced manner. Time-of-day changes in intra-aural temperature (used as a marker of the body clock), grip strength, reaction times, flexibility (markers of aspects of performance), juggling and dribbling tasks, and wall-volley test (football-specific skills) were compared. Significant (repeated measures analysis of variance, ANOVA) diurnal variations were found for body temperature (p 0.05). Diurnal variation was found for performance tests, including sit-and-reach flexibility (p<0.01) and spinal hyper-extension (p<0.05). Peaks occurred between 16:00 and 20:00 h and the daytime changes paralleled the temperature rhythm. Diurnal variation was also found for football-specific tests, including dribbling time (p<0.001, peak at 20:00 h) and chip test performance (p<0.01), being more accurate at 16:00 h (mean error=0.75 m) than at 08:00 h (mean error=1.01 m). Results indicate football players perform at an optimum between 16:00 and 20:00 h when not only football-specific skills but also measures of physical performance are at their peak. Body temperature peaked at a similar time, but positive mood states seemed to peak slightly earlier. While causal links cannot be established in these experiments, the results indicate that the diurnal variation of some aspects of football performance is affected by factor(s) other than body temperature alone.
