"Aerobics" was coined by Dr. Cooper, an exercise physiologist at
the San Antonio Air Force Hospital. He was the first to develop a
formula for a target heart rate. Although there have been more recent
improvements on this original formula, Dr. Cooper's heart rate formula
involved subtracting your age from 220 and exercising at a heart rate of
60-80% of that number. Although "aerobics" were originally designed to
help astronauts, Dr. Cooper soon realized that this would be a
beneficial type of exercise for everyone.
Since then the original formula has been improved upon, and studies have demonstrated more benefits of regular aerobic exercise, including:
*Weight loss and maintaining a healthy weight (Aerobic exercise burns fat!)
*Increased long-term energy and stamina
*Improved mood
*Pain relief (by natural endorphin production)
*Stronger heart and better circulation (by keeping arteries clear and preventing heart disease)
*Improved blood sugar control and adrenal health
*Lower blood pressure
*Stronger bones (weight bearing aerobic exercise helps prevent osteoporosis)
*Stronger immune system
*Longer life expectancy
If you're suffering from low energy, dwindling endurance, aches and pains, excessive body fat, stress, or if you crave sugar or carbs, chances are you're not getting enough aerobic exercise!
The intensity and duration of exercise determine whether the muscles work aerobically or anaerobically. Aerobic exercise requires a very specific level of intensity for a minimum of thirty minutes. If the heart rate is too low or too high, the exercise becomes anaerobic instead.
During true aerobic exercise, the body burns fat for energy. This process requires oxygen, hence the term "aerobic." Aerobic exercise is useful for improving muscle endurance (allowing them to function for hours or days at a time without fatigue). This is especially important for those muscles that support posture, joints, and the arches of the feet. Therefore, if there is not sufficient aerobic exercise, the chances of joint problems, injuries, and low stamina increase.
In anaerobic exercise, sugar (glucose) is burned for energy. This process does not require oxygen. Burning sugar helps provide muscles with short-term speed and power. However, muscles cannot burn sugar for long, so they tire quickly. Most people have no shortage of anaerobic exercise. Even while seated, the body runs many tasks anaerobically, and virtually all sports are anaerobic due to their alternating bursts of high intensity activity and rest.
Dr. Phil Maffetone is an internationally recognized researcher who has greatly improved our understanding of aerobic exercise and endurance training. He studied many variables, including heart rate, gait, and muscle imbalances in many athletes before and after workouts. Dr. Maffetone discovered that the athletes who exercised using Dr. Cooper's original formula often ended up over-training and suffering from injuries, pain, joint problems, and distorted posture and body mechanics. His work led Dr. Maffetone to develop a new and improved formula for calculating each person's target heart rate for true aerobic exercise.
There are just four simple steps to proper aerobic exercise and all its benefits:
1. Invest in a heart rate monitor with a chest strap as well as a wrist watch/display. It's not a good idea to exercise without one because you'll have no way of knowing if you're at the right pace. There are many brands and models available. Polar is an industry leader and is usually a safe bet. If you work out in a gym, invest in a model that is coded so that there is no signal interference from other electrical devices nearby.
2. Calculate your maximum aerobic heart rate using Dr. Maffetone's formula. Simply subtract your age from 180. For example, a 32 year old who wants to exercise aerobically would have a maximum heart rate of 148 beats per minute. Modifiers and exceptions to this formula include:
*Subtract another 10 from the max heart rate if you're recovering from a major illness or surgery, or if you take any regular medications.
*Subtract another 5 from the max aerobic heart rate if you're injured, have regressed in competition or training, suffer from more than two bouts of cold/flu each year, have asthma or allergies, are just beginning to train, or if you have not been training consistently (Dr. Maffetone defines consistency as at least 4 times per week for 2 years).
*Add 5 to the max heart rate if: training consistently for more than 2 years without any injuries or problems and have made progress in competition.
*Add 10 to the max heart rate if you're over the age of 65.
*This formula does not apply to those age 16 or younger. The best bet for these athletes is 165 as the max heart rate.
*If in doubt, choose the lower maximum heart rate.
3. Calculate your minimum aerobic heart rate. Simply subtract 10 points from the maximum aerobic heart rate. So a healthy 32 year old would have a max of 148 and a minimum of 138.
4. Walk, jog, bike or swim while wearing your heart rate monitor. Stay within your aerobic heart rate zone for at least 30 minutes at a time, and do this at least three times per week. I don't advise exceeding 90 minutes without a doctor's supervision.
You will discover that it's surprisingly easy to exercise aerobically. It doesn't take much effort to elevate your heart rate to the target zone. That's good news for couch potatoes (talk about exercising smarter, not harder!), but sometimes frustrating for athletes who don't want to slow down their training. However, athletes need to do this to protect their bodies. The silver lining for athletes is that, as your heart becomes more aerobically fit, you'll be able to quicken the pace without exceeding your maximum aerobic heart rate. With your trusty heart rate monitor to guide you, you'll soon also discover that any activity other than running, walking, cycling or swimming (at a steady pace) is likely anaerobic.
As a chiropractor, acupuncturist, and athlete, I've noticed remarkable benefits with aerobic exercise for both myself and my patients. The immediate and long-term benefits are well worth the effort!
