Celebrating 10 Years of Support for 1% For the Planet

Silver Sage  is celebrating 10 years of membership with 1% For the Planet, and has donated more than $116,000 to area environmental groups since January 2007 through this partnership.

By participating in the 1% For The Planet program, member businesses commit to donate one percent of their sales directly to the sustainability-oriented nonprofit(s) of their choosing, after 1% For The Planet has carefully vetted each nonprofit for track record, credibility and impact. For more information, visit http://onepercentfortheplanet.org/.

“More than ever, it’s important that we do what we can to protect the environment,” said Dr. Andrew Pasternak from Silver Sage Center for Family Medicine. “Donating to local environmental charities helps us make sure our patients can experience Mother Nature, which in turn helps their own health. It’s essential that we promote conservation in the Reno/Tahoe area.”

Organizations that have benefited from Silver Sage’s partnership include: Headwaters Science Institute, Truckee River Watershed Council, League to Save Lake Tahoe, Truckee Donner Land Trust, Lahontan Audubon Society, Tahoe Institute for Natural Sciences, Animal Ark, Center for Biologic Diversity, TAMBA, Peregrine Fund, Friends of Nevada Wilderness, Great Basin Bird Observatory, Reno Bike Project, Poedunk, and Truckee Trails Foundation.

Performance Metabolic Efficiency Assessment

What is it and what can it do for you?

by Paige Galeoto

Like many of you, I’ve been riding and competing for many years (sometimes at a national level, often with friends on the local single track). And like many of you I have been winging it, using my experience and knowledge to try and go faster and tire slower. Whether you are a cyclist like me, a runner or other endurance athlete, you’ll likely agree that the older we get, the more important it becomes to train “smarter,” not just harder or longer.

While I acknowledge (begrudgingly) that I have gotten slower as I’ve aged, I have not lost my desire to compete and be challenged. So, how do I keep moving my own personal bar forward? Science! In the form of physiologic testing at Silver Sage Sports and Fitness Labs.

To get this science-informed training going, I scheduled a metabolic efficiency assessment with Julie Young at Silver Sage one Friday afternoon this past February.

What is Metabolic Efficiency?

Our bodies rely on two sources of energy to perform:

  1. Carbohydrates
  2. Fat

We’ve all heard of carbo-loading before races or big events. The reason we load up on this fuel source is carbohydrates are most quickly converted into energy. However, the body can only store about 2,000 calories of carbohydrates (in the form of glycogen) so you and I will run out of carb energy after 2-3 hours of moderate exercise. In contrast, fats are more slowly converted into energy and the body has tons of fat to draw on (nothing personal, we all have tens of thousands of calories to draw on, no matter our size).

A metabolic efficiency assessment (ME) tells us how well our body utilizes fat as an energy source. Armed with this info, you can improve your efficiency through exercise and nutrition.

The test is particularly valuable for true endurance athletes whose target events are 4 to 6 hours or more, but even for those whose events are shorter (my target events range from 45 minutes to four hours) this information can help us maintain energy and performance levels throughout any event without trying eat constantly. I wanted help tackling these challenges:

  • Cramping at about the 2 ½ hour mark of a race or hard effort
  • Fading near the end of a race (of any length) after a strong start

The test

Unlike a VO2 max test, the ME test is not an all-out, tongue-to-your-knees effort. The test at Silver Sage was done on their trainer, using my bike. You get to wear some fancy head gear with a tube connected to your mouth and your nose plugged (testing your respiration gasses), and a heart rate monitor strap. It’s a bit awkward, but the effort is a low cadence endurance effort so no labored breathing.

You pedal easy, increasing 10 to 25 watts every five minutes. And every five minutes, Julie pricks your ear to take a blood sample and get your lactate level. (It doesn’t hurt, promise.) The whole thing takes about an hour.

Upon completion, this is what you’ll learn:

  1. Caloric expenditure at various heart rates and intensities
  2. How to preserve carb stores to decrease the required fuel replenishment
  3. How to increase fat as fuel, so you can perform workloads faster and longer
  4. Lactate levels for your various metabolic zones

What to do with your data:

A few days later, Julie sent me my results. The executive summary: I do not burn fat — at all. It’s all very math-ey, but the point where I am burning equal parts carbs and fat — which you’d hope would be well into your endurance zone, is 75 watts or 130 heart rate. For me that’s barely moving. In contrast, Sian Turner, a pro-level cyclist and triathlete who is quite efficient in her metabolism, burns equal parts carbs and fat up to 180 watts. And she improved that number from 110 watts, over the course of a year, the same way I will attempt to improve mine:

  1. Exercise more at lower intensities, especially early in a training cycle
  2. Support stable blood sugars by eating more lean proteins, healthy fats, fruits, and vegetables instead of high carbohydrate food

Nutrition as asset

I took this test because I am committed to making an improvement in my cycling performance. For me, the results have led to a pretty significant change in my diet. While I’ve always eaten what I considered good, healthy food, I was very carb heavy and I was consuming more processed carbs than I realized. I spent 6 weeks limiting my carb intake to 25 percent of calories and am now allowing myself about 35 percent (I followed the Always Hungry plan at the recommendation of another endurance athlete). I also started training with Julie, who has me spending more time in low and medium endurance zones than I have ever trained in before in my 25 years of cycling.

I am still relatively early in my process. Seven weeks after adjusting my diet and five weeks after starting my new training program, I had a “test” – a rolling metric century with a group of hard-charging friends. Fueled with almost all fat and protein, I rode four hours and climbed 3,500 feet without bonking or cramping. However, at the final rest stop I ate some potatoes which provided a nice energy surge for the final miles.

This reinforces another point both Julie and Sian made to me — phase your nutrition with your training. While I am doing some experimenting with my diet right now, I am erring on the extreme side and finding the break points. Our daily nutrition needs can and should change with our workouts. On a rest week I can really lower carbs, but for my upcoming race I will fuel the night before and day of with carbs and also use carbs in recovery. An all or nothing approach is not ideal.

Take away

Do less guessing. Let science aid your training efforts by telling you where your deficiencies are and how you can train smarter, not harder. As athletes, we are extremely lucky to have Silver Sage’s Olympic-training center caliber testing facilities available and a testing staff that knows how to help you translate that data into performance gold.

See you at the start line.
