Taking the Scientific Method to the Field.

always thought scientists were nerds. I should know. After 12 years of multiple

university educations, including a year of classes in medical school, I’ve been around many of them. But I decided that, as a graduate student, I was going to be different. I figured that I had to be if I was to stay focused on my real interest: running. Combining running and school isn’t easy. Although my main interests in exercise physiology center on endurance performance and training distance runners, my academic adviser keeps reminding me that I am in the world of academia now, and so instead of writing articles on coaching and training, I should be spending my time writing research articles for scientific journals. However, writing research articles requires doing research, something I would rather save for the real scientists. I would rather be coaching.

And then I met Heather.

I started coaching her in October 2001. She was a 3:13 marathoner who was looking for a coach. I was a coach looking for an athlete. A doctoral student herself (in theater and drama), she was the first to tell me she is not a scientist. Ismiled.

I trained Heather the only way I know how—by asking myself what the sources of fatigue are for the events she competes in and then training her body to withstand or delay that fatigue. Each phase of Heather’s training, each week, each workout, was designed around a physiological purpose.

I was often taken aback when I saw Heather run fast, not because I doubted her, but because I am continually impressed at how well this physiology stuff works. You can learn a million times in the classroom or from doing research that endurance training increases glycogen storage in skeletal muscles or that VO,max, which is so often talked about, is actually a rather stable parameter of aerobic fitness, but it is all theoretical until you see it for yourself. The enviable access I have to a human-performance laboratory allowed me to see things about Heather that few coaches get to see. As she ran to exhaustion on the treadmill, biting down on a tube connected to oxygen and carbon dioxide analyzers, I saw that
