**Flagstaff Fitness: Altitude Lies About Calorie Burn?**
By Franklin Everett ShawForget the latest diet fads and influencer-hyped workouts. If you’re trying to manage your weight or improve your fitness in Flagstaff, Arizona, you’re fighting a battle most people don’t even know exists: altitude. Those calorie counts on your fitness tracker? They’re probably lying to you.
Flagstaff sits at nearly 7,000 feet above sea level. This isn’t just a scenic backdrop; it’s a physiological game-changer. We need to understand how this altitude affects our bodies, and more importantly, how to adjust our expectations and training to get real results.
Your basal metabolic rate (BMR), the energy your body burns at rest, is affected by altitude. Studies show that BMR can increase by as much as 8-25% at altitudes above 6,000 feet. This is because your body works harder to get the oxygen it needs.
Think of it like this: your car engine has to work harder to climb a steep hill. It burns more fuel. Your body is the same.
So, how do you account for this? First, understand that your fitness tracker doesn’t. It’s using algorithms based on sea-level data. You need to correct its estimations.
Here’s a practical approach:
Calculate your sea-level BMR: Use an online BMR calculator. Many are available; just search “BMR calculator.” These typically require your age, sex, weight, and height.
Apply the altitude adjustment: Multiply your sea-level BMR by a factor to account for the altitude increase. A conservative estimate is 1.08 (an 8% increase). For a more aggressive approach, use 1.25 (a 25% increase). Start with the lower end and see how your body responds.
Track your actual weight and adjust: This is crucial. The adjusted BMR is still an estimate. Weigh yourself regularly (ideally at the same time each day) and monitor your progress. If you’re not losing weight (or gaining, depending on your goals), adjust your calorie intake accordingly.
For example, let’s say your sea-level BMR is 1500 calories. At Flagstaff’s altitude, your adjusted BMR could be 1500 * 1.08 = 1620 calories. This means you’re burning an extra 120 calories per day just by existing in Flagstaff.
But it’s not just about BMR. Exercise is also different at altitude.
The lower oxygen levels mean your heart rate will be higher for the same level of exertion compared to sea level. This is where many people make mistakes. They push themselves too hard, too soon.
A common pitfall is trying to maintain the same pace or intensity as you would at sea level. This can lead to overtraining, injury, and burnout.
Instead, focus on perceived exertion. Use the Rate of Perceived Exertion (RPE) scale. This is a subjective scale from 1 to 10, where 1 is resting and 10 is maximal effort.
Aim for a RPE of 5-7 during moderate-intensity workouts. Don’t worry about your pace or heart rate initially. Let your body adapt.
Here’s a step-by-step guide to adjusting your workouts:
Start slow: Reduce your usual workout intensity by 20-30%. This might feel easy at first, but it’s crucial for acclimatization.
Monitor your heart rate: Use a heart rate monitor to track your heart rate during workouts. Aim for a heart rate that’s 10-15 beats per minute lower than your sea-level target heart rate.
Listen to your body: Pay attention to how you feel. If you’re feeling excessively fatigued or short of breath, slow down or stop.
Gradually increase intensity: As you acclimatize, gradually increase the intensity and duration of your workouts. Don’t increase both at the same time. Increase one, then the other.
Consider altitude training: If you’re serious about performance, consider incorporating altitude training into your routine. This involves spending time at higher altitudes to improve your body’s ability to use oxygen.
Another challenge in Flagstaff is the dry air. This can lead to dehydration, which can further impair performance and increase fatigue.
Make sure you’re drinking plenty of water throughout the day. A good rule of thumb is to drink half your body weight in ounces of water. For example, if you weigh 150 pounds, aim for 75 ounces of water per day.
Electrolyte imbalances are also common at altitude. Consider adding electrolytes to your water, especially during and after workouts.
Now, let’s talk about nutrition. While your BMR might be higher, it doesn’t give you a license to eat whatever you want.
Focus on nutrient-dense foods that will fuel your workouts and support your recovery. This includes plenty of fruits, vegetables, lean protein, and whole grains.
Avoid processed foods, sugary drinks, and excessive amounts of saturated and unhealthy fats. These can hinder your progress and make it harder to acclimatize to the altitude.
A common mistake is to drastically increase calorie intake without considering the quality of those calories. This can lead to weight gain and other health problems.
Instead, focus on making small, sustainable changes to your diet. Add more fruits and vegetables, swap sugary drinks for water, and choose lean protein sources over processed meats.
Here’s a practical tip: plan your meals in advance. This will help you stay on track and avoid making unhealthy choices when you’re hungry.
Finally, remember that acclimatization takes time. It can take several weeks or even months for your body to fully adapt to the altitude.
Be patient, listen to your body, and don’t get discouraged if you don’t see results immediately. With the right approach, you can achieve your fitness goals in Flagstaff, despite the challenges of altitude.
Don’t let those fitness tracker lies hold you back. Take control of your training and nutrition, and you’ll be amazed at what you can achieve.
