If you follow the world of sports and fitness, you might know that "recovery" has become quite the buzzword. On this edition of ST Medical, we're exploring the hype as well as the science behind various recovery products -- such as power bars, energy shakes, foam rollers, electrical muscle stimulators, etc. Our guest is the noted science writer Christie Aschwanden, whose new book is "Good to Go: What the Athlete in All of Us Can Learn from the Strange Science of Recovery." As was noted of "Good to Go" by a critic in the journal Science: "Aschwanden turbocharges [this text] by relentlessly delving into the science behind the most touted treatment regimes.... [Her] persuasive science and snappy writing helped me relinquish some recovery beliefs I'd been holding for years." And further, from The Wall Street Journal: "Deeply researched and artfully written.... A must-read for all athletes, from the professional to the weekend warrior."
