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 [https://medium.com/@jurgenthoelen/belgian-dutch-study-why-in-times-of-covid-19-you-can-not-walk-run-bike-close-to-each-other-a5df19c77d08] 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 A link to the poster covering the study findings can be found here [https://x3training.com/wp-content/uploads/2020/04/ACSM-Poster-final.pdf].
