Recently, I had the opportunity to attend the Healthy Running WV Conference held in Ranson, WV on November 3rd and 4th. There were about 50 attendees from a variety of backgrounds: running coach, MD, PT, DPM, and general runners. I doubt many of them left without having their preconceptions of training, nutrition, or health challenged. And that’s because the two primary presenters, Drs. Mark Cucuzzella and Phil Maffetone, are well known for challenging the status quo. Although both have a long history in exercise performance, lately they are more interested in public health. And for good reason. I wanted to share just a little taste of the information presented.
Attempting to peak for endurance events can be unnecessary, injury causing, and downright unhealthy. Dr. Maffetone suggested that we may really only need 2-4 weeks of speedwork in the final preparation for a competition, and we can perform quite well with no speedwork at all if the aerobic metabolism has been well trained over time. This is quite a bit shorter than the 6-8 weeks recommended by coaches like Arthur Lydiard.
Runners unnecessarily run too fast most of the time. I tell runners this all the time (some believe me, some don’t), but let’s revisit it. Exercise does not have to be uncomfortable to result in health and fitness gains. Dr. Maffetone recounted working with multiple elite and Olympic level athletes that had measurably deficient levels of aerobic fitness who continued to make significant performance gains when he took away their anaerobic training and ultimately trained them at slower speeds.
Food quality is more important to overall health than a specific caloric intake. For everyone, athlete or not, poor quality carbohydrates do an extremely bad job of creating satiety. So guess what? You eat more of them. I’ve hammered my fair share of Oreos and still didn’t feel satisfied. The carbs lead to a dramatic insulin response that can change in magnitude over time. High-quality proteins and fats do a great job of making us feel full sooner and longer after a meal without the dramatic insulin spike. Unprocessed vegetables can even provide a worthy source of carbohydrate. This is not new information to me or many others, but it’s worth repeating for those that are unaware of how prepackaged food, which emphasizes carbs, have made so many things easier to prepare but far less nutritionally valuable.
There are performance and health benefits to emphasizing greater protein and fat macronutrient intake over carbohydrate. Commonly accepted information encourages 60-70% daily carbohydrate intake for endurance athletes. We could get away with 30-40% or even less. Routinely de-emphasizing carbohydrate reliance in training forces the body to rely more on stored fat, which is pretty awesome if you want to run in a marathon or ultramarathon. Then you won’t require as much additional fueling during these longer events, delaying or ultimately preventing the dreaded bonk. Dr. Cucuzzella, who recently maintains a low carb intake, but has run for decades, has the physiology lab data to prove his increase of peak fat burning efficiency from 1.18 grams/minute to 1.9 grams/minute in just a year. These same kinds of beneficial metabolic changes were suspected many years ago by Dr. Tim Noakes in his famous text “Lore of Running.” I’m anxious to see where the research is on this in another 5-10 years.
Sprinting hard at the end of a long event, like a marathon, is more likely to trigger a cardiac event (heart attack) in someone predisposed to having such a cardiac issue. Don’t know if you are at risk? Talk to your physician about finding out your coronary artery calcium score.
A simple glucometer can be an excellent, affordable self-monitoring tool for detecting carbohydrate intolerance and the early onset of insulin resistance that leads to type 2 diabetes. Cucuzzella and Maffetone suggest that people don’t just wake up one day with type 2 diabetes. The changes occur over time because of poor nutritional quality. By the way, a few years back we called type 2 diabetes “adult onset” to differentiate it from the type 1 diabetes that people can have at birth. Unfortunately, that has become a misnomer because young children have begun to acquire type 2 diabetes as the American diet has emphasized low-quality processed carbohydrates since the 1980s.
Insulin resistance is a common factor to a variety of diseases. There is growing evidence that issues such as cardiovascular disease follow long term metabolic changes associated with a high carbohydrate diet. Older research focused on cholesterol but the tide is shifting.
