Inside Tracker has been on a major advertising blitz of late making a huge push for new customers in an effort to get more athletes to spend hundreds of dollars on their blood testing services. I reviewed Inside Tracker a long time ago but given the surge in advertising and the promise of improved health and even performance to those who might be seduced in to signing up, I thought that it was time to revisit my original overview. Is a service like this helpful or in any way useful to improving health or athletic performance? I replay my original segment from Episode 4 and update it with some new insights. Also, a conversation with Canadian exercise physiologist and researcher Kate Wickham. Kate has in her early career already established herself as a quality researcher looking to reduce the gender gap in her field. We discuss some of her work as well as some of the limitations of exercise science research in general.
