In this episode I address listener queries from a recent Webinar I conducted for the British Association of Sport and Exercise Scientists.
- What are your favourite sleep supplements?
- Any previous research on how the amount of sleep can impact on YOUNG CHILDREN?
- Are short naps (30min) really the best way to recover or would you recommend longer napping time? Would it differ for match day?
- As a PT I often start early finish late is napping or one long sleep a week the same as regular 8 hrs?
- At what range of rest (hrs of sleep) is it deemed dangerous to train? (i.e high injury risk)
- Best strategies to promote sleep in soccer players when kick off is 8pm
- Can nutritional intake affect sleep?
- Can u clarify what you mean by 'athlete', and to what extent ur principles apply to non-professional athletes?
- Current gaps in research with regards to sleep and elite team sport athlete’s wellbeing.
- Does sleep requirement change or just the type of sleep during high-volume training periods? how is this best managed?
- How can we trust actigraphy data from a third party ie Fatigue science vs raw actigraphy data?
- How do you get more Slow Wave Sleep? What if after analyzing the sleep cycles that although asleep you stay in your light sleep
- How to deal with a jet lag
- I am interested in the sleep strategies employed for prolonged military excursions.

Tim Smithies recently completed his BSc (Hons) at the University of Western Australia. Supervised by Dr. Ian Dunican, Dr. Jennifer Walsh and Prof. Peter Eastwood, his honours project was with the former Super Rugby team (and most travelled professional sporting team in the world) the Western Force, and aimed to assess how long distance international travel affects the sleep of Super Rugby players. Furthermore, the project assessed how this travel can affect the team's game performance. Tim also plays premier grade cricket in Perth, and is travelling to the U.K. this year to play cricket.
You can contact Tim at email@example.com and obtain a copy of his thesis via email.

Maddison graduated from the University of Western Australia with a Bachelor degree and Honours in Sport Science. In conjunction with the Western Australian Institute of Sport, she has been investigating the influence of evening electronic device use on sleep in athletes for her PhD, which is currently in the final review phase. Maddison has worked with a range of Olympic sports in the Physiology departments at the WA Institute of Sport and the Australian Institute of Sport, particularly with the Sailing and Rowing programs. An ex-rower herself, she has also coached high school rowing since 2009. She has recently moved to Brisbane and hopes to continue helping people improve their sleep and athletic performance.
