Comparing Subjective With Objective Sleep Parameters Via Multisensory Actigraphy in German Physical Education Students

Abstract

This study compared subjective with objective sleep parameters among 72 physical education students. Furthermore, the study determined whether 24-hr recording differs from nighttime recording only. Participants wore the SenseWear Armband™ for three consecutive nights and kept a sleep log. Agreement rates ranged from moderate to low for sleep onset latency (ICC = 0.39 to 0.70) and wake after sleep onset (ICC = 0.22 to 0.59), while time in bed (ICC = 0.93 to 0.95) and total sleep time (ICC = 0.90 to 0.92) revealed strong agreement during this period. Comparing deviations between 24-hr wearing time (n = 24) and night-only application (n = 20) revealed no statistical difference (p > 0.05). As athletic populations have yet to be investigated for these purposes, this study provides useful indicators and practical implications for future studies.

Changes in sleep pattern and sleep quality during COVID-19 lockdown

“…Although multiple subjective and objective measures are available to assess sleep patterns and sleep patterns longitudinally, for example, sleep diary and actigraphy, use of recall method for sleep pattern has a moderate correlation with objective methods. [ 9 10 ] Moreover, methods of objective estimation of sleep pattern and duration amount for only 20% variation. Thus, the recall method can reliably be used to estimate the sleep pattern over short periods.…”

Sleep-Related Issues for Recovery and Performance in Athletes

“…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. 11 This is supported by a recent review in which the effects of sleep loss on exercise performance, physiological responses to exercise and cognitive functions are analysed.…”

The influence of training load, exposure to match play and sleep duration on daily wellbeing measures in youth athletes

“…The use of a daily s-RPE total also cannot be extrapolated to dose-response changes in fitness unlike other internal load measures, such as heart rate monitoring (Taylor et al, 2018). Self-reported sleep duration has also been criticised in the past as previous studies have shown it can be overestimated by as much as 1-1.5 hours (Caia et al, 2017;Kölling et al, 2016;Lauderdale et al, 2008), suggesting actigraphy may be a more appropriate measure.…”

“…Despite this evidence showing the importance of sleep, previous studies have avoided the use of self-reported sleep duration as a predictor of changes in wellbeing measures due to its perceived lack of validity when compared to actigraphy measures (Lauderdale, Knutson, Yan, Liu, & Rathouz, 2008). However, it has recently become apparent that in athletic populations self-reported sleep duration is a valid measure when compared to actigraphy (Caia et al, 2017;Kölling, Endler, Ferrauti, Meyer, & Kellmann, 2016), although it maintains its systematic bias of overestimating sleep duration by around 1 hour. These new findings, alongside suggestions that perceptions of sleep quality are not always congruent with objective measures (Krystal & Edinger, 2008), provide rationale for the use of self-reported sleep duration as a predictor of changes in wellbeing.…”
