50 - Professor Sean Peterson

• 3:30 academic papers in the time of COVID
  • How can we see so many studies with such fast turn-around times when it typically takes months to get a paper published
  • Utility overrides rigor in some cases
• 16:00 the fluid mechanics of disease transmission
• 17:30 Sean’s thoughts on the now-famous Dutch / Belgian analysis of COVID spread during running and cycling as published on Medium.
• 20:30 the risks of transmission when training  indoor vs outdoor
  • Outdoors, there is a lot of air mixing, diluting the concentration of viral particles in the airflow
  • Indoors, the air is stagnant and transmission is much easier
• 28:00 Sean’s study of the efficacy of athlete cooling in hot and humid environments
  • Subjects cycled at 60-70% of FTP under 30C and 70% humidity for 45 minutes
  • Cooling accomplished by exposing the inner forearm to a temperature of 5C
  • Test group saw a mitigation in core body temperature rise by 0.5C / hou compared with control group
  • RPE also lower under cooled conditions vs control
• 43:00 the possible difference in the effect of cooling between males and females
• 46:30 the reason why repeated tests are not common in engineering or physiology
  • Funding and publishing incentives discourage non-novel studies
• 51:00 Michael’s least favourite experimental setup
• 52:45 DRDC study torture story
• 54:00 academic funding
