I talk to Dr Ian Dunican, a sleep researcher who has worked with elite combat sports athletes at the Australian Institute of Sport on strategies to help optimise sleep, recovery and performance and who is himself a Brazilian Jiu-Jitsu practitioner and Ultra-Marathon Runner. We discuss sleep cycles, optimising training load and dealing with night time jitters after a workout and sleep tracking gadgets like the oura ring and whoop device. Finally, why martial artists try and cheat the sleep system and how instead they can sleep in and win.
