“…Research regarding the efficacy of napping is limited, but it seems that beneficial effects can be detected following sleep restriction 42 as well as following a 'normal' night of sleep. 43 However, Petit and colleagues 44 did not find positive effects of a 20-min nap on performance. On the other hand, they did not find negative effects on performance or on sleep architecture either.…”

The body of research that reports the relevance of sleep in high-performance sports is growing steadily. While the identification of sleep cycles and diagnosis of sleep disorders is limited to lab-based assessment via polysomnography, the development of activity-based devices estimating sleep patterns provides greater insight into the sleep behaviour of athletes in ecological settings. Overall, small sleep quantity and/or poor quality appears to exist in many athletic populations, though this may be related to training and competition context. Typical sleep-affecting factors are the scheduling of training sessions and competitions as well as impaired sleep-onset as a result of increased arousal prior to competition or due to the use of electronic devices before bedtime. Further challenges are travel demands which may be accompanied by jet-lag symptoms and disruption of sleep habits. Promotion of sleep may be approached via behavioural strategies, such as sleep hygiene, extending night-time sleep or daytime napping. Pharmacological interventions should be limited to clinically-induced treatments as evidence among healthy and athletic populations is lacking. To optimise and manage sleep in athletes, it is recommended to implement routine sleep monitoring on an individual basis.

“…One should consequently ask if napping may disturb subsequent night sleep, especially among players who are not accustomed to napping during the week. Petit et al [87] examined the effects of a postprandial 20-min nap on subsequent sleep in athletes. Postlunch naps were scheduled at 1:00 p.m. with subjects required to lie on a bed in a darkened room for 1 h. Subjects were awakened by intercom when approximately 20 min of sleep had elapsed.…”

“…In the normal sleep condition without napping, the sleep onset latency in a post-trial night was 13.3 ± 5.5 min and increased significantly after post-lunch naps, reaching higher values (24.3 ± 11.8 min; p \ 0.01). Consequently, a daytime nap may be encouraged as a strategy to counteract sleep debt and sleepiness [29]; however, it may induce more difficulties in falling asleep in the subsequent night [87]. Additionally, taking a nap may be associated with less efficient sleep the next night [88].…”

Stress, Sleep and Recovery in Elite Soccer: A Critical Review of the Literature

et al. 2015

View full text Add to dashboard Cite

In elite soccer, players are frequently exposed to various situations and conditions that can interfere with sleep, potentially leading to sleep deprivation. This article provides a comprehensive and critical review of the current available literature regarding the potential acute and chronic stressors (i.e., psychological, sociological and physiological stressors) placed on elite soccer players that may result in compromised sleep quantity and/or quality. Sleep is an essential part of the recovery process as it provides a number of important psychological and physiological functions. The effects of sleep disturbance on post-soccer match fatigue mechanisms and recovery time course are also described. Physiological and cognitive changes that occur when competing at night are often not conducive to sleep induction. Although the influence of high-intensity exercise performed during the night on subsequent sleep is still debated, environmental conditions (e.g., bright light in the stadium, light emanated from the screens) and behaviours related to evening soccer matches (e.g., napping, caffeine consumption, alcohol consumption) as well as engagement and arousal induced by the match may all potentially affect subsequent sleep. Apart from night soccer matches, soccer players are subjected to inconsistency in match schedules, unique team schedules and travel fatigue that may also contribute to the sleep debt. Sleep deprivation may be detrimental to the outcome of the recovery process after a match, resulting in impaired muscle glycogen repletion, impaired muscle damage repair, alterations in cognitive function and an increase in mental fatigue. The role of sleep in recovery is a complex issue, reinforcing the need for future research to estimate the quantitative and qualitative importance of sleep and to identify influencing factors. Efficient and individualised solutions are likely needed.

“…imal sleep inertia and contains mostly stage 2 non-REM sleep. Nonetheless, in a previous study, Petit et al [35,36] reported that this type of nap between 13:00 and 14:00 h or 08:00 and 09:00 h in non-shifted and shifted conditions respectively did not improve anaerobic physical performance but modified the circadian rhythm parameters. Conversely, research has consistently shown that daytime napping improves reaction times, attention [5,7,39,42], memory consolidation [33] and enhances physiological alertness [6,20,22,43].…”

Post-lunch sleepiness belongs to biological rhythms. Athletes take a nap to counteract afternoon circadian nadir, in prevision of disturbed sleep. This study examined the effects of brief post-lunch nap on vigilance in young and healthy athletes. The P300 components, physiological and cognitive performances were assessed either after nap or rest, following a night of normal sleep (NSC) or simulated jet lag condition (5-h advance-JLC). P300 wave is the positive deflection at about 300 ms in response to a rare stimulus, representing higher information processing. P300 amplitude reflects the amount of attention allocated whereas P300 latency reflects time spent on stimulus classification. P300 amplitude was significantly increased (Fz:11.14±3.0vs9.05±3.2 µV; p<0.05) and P300 latency was shorter (Pz:327.16±18.0vs344.90±17.0 ms; p<0.01) after nap in NSC. These changes were accompanied by lower subjective sleepiness (19.7±9.6vs27.5±16.5; p<0.05) and decrease in mean reaction times (MRT: divided attention, 645.1±74.2vs698±80.4 ms; p<0.05). In contrast, in JLC, only P300 amplitudes (Fz:10.30±3.1vs7.54±3.3 µV; p<0.01 and Cz: 11.48±3.1vs9.77±3.6 µV; p<0.05) increased but P300 latencies or MRT did not improve. These results indicated improvements in speed of stimulus evaluation time. Napping positively impacts on cognitive processing, especially when subjects are on normal sleep schedules. A nap should be planned for athletes whose performance requires speedy and accurate decisions.
