The show aired from 2007-2017, first on Fox Sports as hour-long episodes for two seasons, then on ESPN in segment form within the network’s other programs. It featured scientific experiments that tested common notions about athletes, their abilities and the capacity of the human body.

In addition to the participation of numerous sports stars, Brenkus would often take part in the experiments, putting himself “in harm’s way for the sake of scientific discovery,” as ESPN once put it.

“Standing a very average 5’ 8” tall, and tipping the scales at an equally average 160 pounds, Brenkus intersperses his hosting and executive producing duties on Sport Science with performances as the show’s ‘Everyman,’ to help demonstrate what happens when a regular guy steps on the field, into the ring, or on the court with top athletes at the top of their games,” a 2009 ESPN press release stated. “Along the way, he helps audiences understand their own physiologies and how to improve their overall performance, health and well-being.”

“John was uniquely talented and singularly brilliant at not only analyzing sports but then translating sports and science to generations of fans in memorable ways, because John was memorable,” Scott said. “… This world was a better place with John Brenkus in it.”
