In this episode of S4P we take a look at "Do players and staff sleep more during the pre- or competitive season of elite rugby league?" by Johnpaul Caia, Tannath J. Scott, Shona L. Halson & Vincent G. KellyThis study establishes the sleep behaviour of players and staff during the pre- and competitive seasons of elite rugby league. For seven days during both the pre- and competitive seasons, seven rugby league players and nine full-time staff from one professional Australian rugby league club had their sleep monitored via wrist actigraphy and self-report sleep diaries. Two-way
repeated measures analysis of variance determined differences between the pre- and competitive season in players and staff, with effect sizes (ES) used to interpret the practical magnitude of differences. Findings show an earlier bedtime and wake time for players (−34 min, ES = 1.5; ±0.5 and −39 min, 2.1; ±0.5 respectively) and staff (−29 min, ES = 0.8; ±0.3 and −35 min, ES = 1.7; ±0.4 respectively) during pre-season when compared to the competitive season. Despite this, no differences were seen when considering the amount of time in bed, sleep duration or sleep efficiency obtained between the pre- and competitive seasons. Our results suggest that early morning training sessions scheduled during pre-season advances wake time in elite rugby league. However, both players and staff can aim to avoid reductions in sleep duration and sleep efficiency with subsequent adjustment of nighttime sleep patterns. This may be particularly pertinent for staff, who wake earlier than players during both the pre- and competitive seasons.

Ian C. Dunican, Jennifer Walsh, Charles C. Higgins, Maddison J. Jones, Kathleen Maddison, John A. Caldwell, Hillman David & Peter R. Eastwood (2018) Prevalence of sleep disorders and sleep problems in an elite super rugby union team, Journal of Sports Sciences, DOI: 10.1080/02640414.2018.1537092
The aim of this study was to determine the prevalence of sleep disorders in an elite rugby union team using in-laboratory polysomnography (PSG) and sleep questionnaires. Twenty-five elite rugby union players underwent a night of PSG during the “off-season” of the Super Rugby competition to assess their sleep. Of interest were measurements that detected the presence of obstructive sleep apnea (OSA; apnea-hypopnea index ≥5 events/hr) and the presence of moderate-severe periodic leg movements during sleep (PLMs; ≥15 events/hr). Players completed sleep-related questionnaires to assess daytime sleepiness, perception of insomnia, risk of OSA, and the presence of restless legs syndrome (RLS) and underwent basic anthropometric assessments including body mass index and neck circumference. OSA was present in 24% (n=6) of players and PLMs ≥15 events/hr in 12% (n=3). Questionnaire responses showed that all players had insomnia defined subthreshold insomnia and excessive daytime sleepiness, two players were identified as being at risk for OSA and none were classified as having RLS. In conclusion, sleep disorders and excessive sleepiness are common in elite rugby union players. A process to identify and manage sleep disorders should be considered by teams to optimise their physical recovery, athletic performance and to safeguard their health.

In this episode we take a look at sleep in a fly in fly out mining operation.
Abstract: Good sleep is essential for optimal performance, yet few studies have examined the sleep/wake behaviour of elite athletes. The aim of this study was to assess the impact of early-morning training on the amount of sleep obtained by world-class swimmers. A squad of seven swimmers from the Australian Institute of Sport participated in this study during 14 days of high-intensity training in preparation for the 2008 Olympic Games. During these 14 days, participants had 12 training days, each starting with a session at 06:00 h, and 2 rest days. For each day, the amount of sleep obtained by participants was determined using self-report sleep diaries and wrist-worn activity monitors. On nights that preceded training days, participants went to bed at 22:05 h (s=00:52), arose at 05:48 h (s=00:24) and obtained 5.4 h (s=1.3) of sleep. On nights that preceded rest days, participants went to bed at 00:32 h (s=01:29), arose at 09:47 h (s=01:47) and obtained 7.1 h (s=1.2) of sleep. Mixed model analyses revealed that on nights prior to training days, bedtimes and get-up times were significantly earlier (p<0.001), time spent in bed was significantly shorter (p<0.001) and the amount of sleep obtained was significantly less (p<0.001), than on nights prior to rest days. These results indicate that early-morning training sessions severely restrict the amount of sleep obtained by elite athletes. Given that chronic sleep restriction of <6 h per night can impair psychological and physiological functioning, it is possible that early-morning schedules actually limit the effectiveness of training

In this weeks episode we review a paper I had published earlier this year.
Laboratory and home comparison of wrist-activity monitors and polysomnography in middle-aged adults.
https://link.springer.com/article/10.1007/s41105-017-0130-x
Accurate measurement of time at lights out is essential for calculation of several measures of sleep in wrist-activity monitors. While some devices use subjective reporting of time of lights out from a sleep diary, others utilise an automated proprietary scoring algorithm to calculate time at lights out, thereby negating the need for a sleep diary. This study aimed to compare sleep measures from two such devices to polysomnography (PSG) measures (In laboratory) and against each other when worn at home (At home). Fifty middle-aged adults from the Raine Study underwent overnight PSG during which they wore an ActiGraph™ and a Readiband™. They also wore both devices at home for 7 nights. The Readiband uses an automated proprietary algorithm to determine time at lights out whereas the ActiGraph requires completion of a sleep diary noting this time. In laboratory, compared to PSG: Readiband underestimated time at lights out, sleep onset, and wake after sleep onset, overestimated sleep latency and duration (p < 0.001 for all); while ActiGraph underestimated sleep latency and wake after sleep onset and overestimated sleep efficiency and duration (p < 0.001 for all). Similar differences between devices were observed on the laboratory night and when at home. In conclusion, an automated algorithm such as the Readiband may be used in the same capacity as the ActiGraph for the collection of sleep measures including time at sleep onset, sleep duration and time at wake. However, Readiband and ActiGraph measures of sleep latency, efficiency and wake after sleep onset should be interpreted with caution.

In this week's sleep science audio abstract we take a look at the adverse childhood experiences (ACEs). ACE represents substantial threats to public health and affect about 58% of youth in the US. In addition to their acute effects such as injury and physical trauma, ACEs are associated with an increased risk of several negative health outcomes throughout the life course. Emerging evidence suggests sleep disorders may be one such outcome, but existing studies have not been systematically reviewed and summarized. This systematic review summarizes the evidence concerning the relationship between ACEs and sleep disorders and disturbances, with a focus on adult women.

S4P Radio Season 2, Episode 10 with Rob Wilson; The Art of Breath
Thursday Sep 27, 2018
Thursday Sep 27, 2018
Rob Wilson comes from a formal education in manual therapy with 15+ years of experience as both a practitioner and teacher. He resides in Virginia Beach, VA with his wife Thomi where they have owned and operated CrossFit Virginia Beach since 2006.In the past decade and a half Rob has had the good fortune to work with an enormous variety of athletes ranging from amatuer, nationally and internationally ranked athletes in everything from power lifting and sailboat racing, to individuals in the US Naval Special Warfare Program.
Rob truly enjoys working with the tactical communities of the U.S. Armed Forces. Over the course of his career he has had the honor to help serve many active duty service members and veterans, through both his private human performance consultation work, and through groups like the Resiliency Project – which seek to further the resources available to military groups.
Prior to creating the Art of Breath series with Brian Mackenzie, where they work closely with Stanford Universities Neuroscience department, Rob was an original member of the world renowned MobilityWod staff under the direction of Dr. Kelly Starrett. Dr. Starrett and MobilityWOD was influential in Rob’s development as a professional in the human performance sector. Rob is a passionate teacher to the core. Throughout the course of his career as a manual therapist and coach one thing became abundantly clear; it’s better to teach a person to fish. Without education athletes are left to unknowingly repeat patterns of behavior that may not be pursuant to the actual desired outcome. That is to say the best remedy is often learning. Rob’s journey is about developing a deeper understanding of human performance to better serve those who wish to actualize their potential.
