Episode Summary: In this month’s episode Jesse Cook (Host) sits down with Dr. Brendan Gabriel to discuss the recently published paper in the journal SLEEP by Dr. Oussama Saidi, Dr. Pascale Duché, Dr. Brendan Gabriel, and colleagues that examined the effect of the timing of high-intensity exercise (afternoon vs. evening) on the sleep, sleepiness, and psychological well-being of adolescent athletes. Additionally, this investigation demonstrated the influential role of circadian type (“chronotype”) on the observed relationships.  Here is a link to the article on the SLEEP journal website. In addition to the interview, this episode also features the 2023 SRS Club Hypnos Data Blitz. An overview of Club Hypnos and the associated data blitz is provided, along with recognition of this year’s participants. To close, the episode includes data blitz-esque overviews of the research presented at the actual data blitz from some of this year’s participants.   Enjoy!   Timestamps: (00:49) – Episode Structure Overview (02:32) – Orientation to Topic of Focus for This Episode’s Interview (06:43) – Brief Biography on Dr. Brendan Gabriel (07:45) – Beginning of Guest Interview with Dr. Brendan Gabriel (10:01) – Dr. Gabriel’s Journey into Sleep and Circadian Research (24:26) – Keyword Association!
