Dear Reader,

Welcome to the July edition of The Bounce from nuBound!

This month we look at the implications of specialization and generalization--they present a tradeoff. Movement toward one end of the spectrum decreases abilities at the other.

Our second topic is a just published study which demonstrates benefits from a low carbohydrate diet compared to a low fat diet.

If you have ideas, thoughts or stories for future issues, please let us know!

"A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, and die gallantly. Specialization is for insects."
-- Robert Heinlein


Robert Heinlein's words (quoted by Mark Rippetoe in his book "Starting Strength") have a particular relevance for athletes. When you are training, you quickly realize that there are tradeoffs.

Triathletes know that the strong quads they develop from cycling have less use in running, which depends more on hamstrings. And vice versa. Likewise, the strong shoulders and back of swimmers are simply extra body mass for a runner or cyclist to carry around a course. The goal is not to be outstanding in any one single discipline, but to have a good balance of skills among the set.

Elite triathlete Desiree Flicker (second in the Ironman World Championships 2006) decided last year to concentrate on running when she qualified for the Olympic Trials by placing second in the Austin Marathon. "Biking hurts your running performance. It tires your legs out and you are using opposing muscle groups. I actually believe you are tearing up yours quads to the point where it hurts when you run."

The other extreme from focus on a single sport is a generalized fitness program like CrossFit. One of their mottoes is: "Our specialty is not specializing." They note that combat, survival, many sports, and life reward this kind of fitness and, on average, punish the specialist.

The answer to the question of specialization or being a generalist for any athlete is a personal one. It depends on goals and desires, and it can shift over time. Like Desiree Flicker's choice to focus on running in pursuit of a slot on the Olympic Marathon Team (She didn't make it, by the way, but I'm certain she's glad that she tried).
The New England Journal of Medicine published a comparative study on the effects of a low-carbohydrate diet, a Mediterranean diet, and a low-fat diet. The result is that the low carb diet showed the highest weight loss, followed by the Mediterranean, while low-fat was the least effective. The study has gotten great attention because it followed a large sample, over the course of several years and it had a low drop out rate.

"This study looked at over 300 people who followed their assigned diets strictly for two years, making this one of the longest diet studies in recent history. The bottom line was that the low-carb diet was hands-down the most impressive at improving health in all areas. Those on the low-carb plan lost more weight, experienced a greater reduction in the dangerous C-reactive protein, lowered their triglycerides, raised their HDL cholesterol and dropped their A1C more than those on either the Mediterranean or the low-fat diets, although the Mediterranean was a close second most of the time."

John Tierny has been following the debate on dietary fat and highlights the favorable reactions of science writer Gary Taube to this study. Made famous by his 2007 book "Good Calories, Bad Calories", Gary Taube has become an effective spokesman for those skeptical of low fat diets.

A good resource for athletes interested in the benefits of a low carbohydrate diet is "The Paleo Diet for Athletes" by Loren Cordain and Joe Friel. Working with renowned nutritionist Loren Cordain is triathlete and coach Joe Friel. Basing their recommendations on the standard "paleo" diet popularized by Cordain (basically, fish, lean meat, vegetables and fruits), they make some modifications prior to, during and post-exercise to provide sufficient carbohydrates during recovery to replenish muscle glycogen.
We just received some newly printed oval bumper stickers with the nuBound logo (4"x6"). They work well on bumpers, windows, walls and other flat non-porous surfaces.

We're currently including them in the box when we ship orders, but if you'd like some before your next order, let us know. Send an email, tell us how many you'd like and please confirm your address.



It's summer. Why are you still inside reading email? Get outside and enjoy it!

We have a busy fall ahead. In September we'll be sponsoring a team at the Reach the Beach Relay and then the following week we'll be at the USAT National Championships in Portland, OR and then the week after that back to Boston for the Marine Corps Honor Run.

Watch for us at other races and events throughout the year to come. As always, make sure to catch The Bounce from nuBound!

Sincerely,

nuBOUND
