“…Studies that monitored sleep with actigraphy in this review used several different sleep–wake thresholds. This is a concern given the interpretation of data will vary depending on the threshold used 17. In addition, while field data are necessary to determine how ‘real-world’ training and competition pressures affect sleep, an inherent limitation of such data is that potentially confounding factors, such as caffeine and alcohol intake, which may influence sleep, cannot be eliminated or controlled for.…”

“…PSG is particularly useful for investigating sleep pathologies, including sleep-disordered breathing15 and sleep disturbances caused by concussion 16. However, PSG is expensive and requires specialised laboratory equipment, making it impractical for monitoring athletes in the field 17. Actigraphy, on the other hand, uses accelerometers embedded in portable devices to record movements that can be analysed using algorithms that estimate sleep quality and quantity 18.…”

“…2 The development of sleep prediction algorithms from actigraphy-based measures has improved the accessibility of measurement in ecologically valid environments, and thus the reporting of sleep-wake behaviours among athletes in different field-based settings. 8,9 Whilst practical, recent validity and reliability data further support their robustness for most sleep variables; yet some limitations do apply given that the underlying algorithms only represent estimations of sleep parameters and might differ considering the diversity of devices, misinterpretations, mishandling as well as technical errors. 8,9,10 Sleep in athletes Aside from physiological restoration and psychological well-being, memory consolidation is a function of sleep that is especially important for athletes in terms of learning procedural skills.…”

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.

“…12 Furthermore, the mean kappa value was higher than what has been reported for actigraphy. 13 The results suggest that IR-UWB radar may become an alternative objective measure to actigraphy. An obvious advantage over actigraphy is that movements can be assessed from many parts of the body simultaneously, such as movement from the extremities as well as respiration movements, which both change notably during sleep.…”
