The Fitness Cardio Secret That Propels Lance Armstrong
What is Lance Armstrong doing that you can do to improve your results? Most people exercise to lose weight, focusing solely on that one single goal. But wait, it is not only about looking aesthetically pleasing, getting in those tight jeans, or losing ten pounds. It is really about improving your health, and human performance. Each day when you are huffing and puffing on the treadmill, focusing vigorously on keeping yourself lean, have you ever thought about what physically is occurring in your body besides burning a bunch of calories? For improved results, more people need to stop focusing solely on calorie burn, and start thinking about improving such fitness values as VO2 Max, or maximum oxygen uptake. What exactly is your VO2 Max? VO2 Max is defined as the highest rate at which oxygen can be taken in and used during high intensity dynamic exercise. When you are exercising aerobically on your treadmill, each and every muscle contraction requires oxygen to break down the fats, carbohydrates, and protein; thus, providing energy (ATP) needed to fuel the muscles in order for movement to occur. Humans, at rest, need 3.5 ml of oxygen, every minute, for each kilogram of body weight just to support the cellular activities in the tissues that keep us alive. Now let's get back to our treadmill. As you increase the speed or incline (intensity), more oxygen is required to transfer the oxygen through the blood and into the muscles. Due to increased intensity during your exercise session, more oxygen is required to initiate the energy releasing process. Now let's take the treadmill up to a speed and incline where you can no longer catch your breath comfortably. The intensity has increase significantly, but you have reached an upper limit on the amount of oxygen you can take in. This is your VO2 Max. VO2 Max values differ from individual to individual. Factors such as age, health, activity levels, training programs, and genetics all affect VO2 Max. A sedentary person has a VO2 Max of around 20 ml of oxygen per kilogram of body weight per minute of exercise. A highly trained endurance athlete can have a VO2 Max of 70 ml/kg/min. Now why does Lance Armstrong win all those bike races? Yes, he has a great training program, a great coach, and great equipment. However, his genetics for an endurance athlete are nothing short of astounding. Do you know his VO2 Max measures around 83-85 ml/kg/min, while an average person's is around 40? For Lance, his success is attributed to a combination of great training, will, desire, and unbelievable genetic makeup. A Super Human Lance: 1. Lungs - 2 times the capacity of the average person 2. Muscle - Accumulates less lactic acid and is more efficient at removing it. 3. Heart - Is about 1/3 larger with a resting heart rate of 32 beats per minute, and peaks around 200 beats per minute. 4. Body Fat - 4-5 percent before the Tour starts, while an average person has 15-20 percent. 5. Food Consumption - Needs 6500 calories per day, and upwards of 10,000 per day when biking in the mountains during his 120 mile race. Truly amazing! How do you improve VO2 Max? Improvement is seen by progressively challenging yourself aerobically with consistent workouts at 60% to 85% of your maximum heart rate (220-age) for an extended period of time. The most important variable is to continue attempting to increase intensity levels of your workouts. Progressively overloading is the key; your body will adapt, and improve your VO2 Max as well as burn more calories for decreased body fat. Now you ask, how can I measure my VO2 Max? For the most accurate measurement, you can go into a hospital, or a University Human Performance Lab and get the test. You will generally use a treadmill or a stationary bike, and be given an oxygen mask to measure your oxygen exchange. You will also be connected with chest electrodes to measure your heart response. The main objective is to walk, bike, or run as the intensity is progressively elevated until it is not possible to go any longer. (You should be cleared or monitored by your physician before attempting a VO2 Max test.) The easier. but not as accurate way, is to do an estimated sub maximal aerobic capacity test. The following is one of the many tests that can be used. Find a 400 meter track, bring a stopwatch, and walk/run as fast as you can go for 12 minutes. Keep track of the number of meters you have gone in 12 minutes, and use the following formula. Distance Covered in Meters - 504.9 / 44.730 = Estimated VO2 Max Here is a rough guide: 4-5 laps covered, your VO2 Max will be around 30. Learn to keep a close eye on your fitness values and try to continually improve them. Improvement will lead to great health benefits, and may result in your goal of decreased body fat (depending upon your nutritional habits.) ______________________________________________ To receive your complimentary subscription to Wellness Word Multimedia Newsletter, visit: http://www.WellnessWord.com right now! ______________________________________________ ** Attention: eZine Editors/Website Owners ** Healthiest Regards, By: Jim O'Connor (The Fitness Promoter)- All Rights Reserved Jim O'Connor, a celebrity Exercise Physiologist from Beverly Hills, California, is the editor of Wellness WORD Multimedia Newsletter, and the author of a popular ebook called Home Gym Shopping Secrets.

Boring Ol' Cardio 01/06/09

The Icon Diet offers a step by step weight loss
Cardio is a very important aspect of any work out. There are numerous benefits to a good cardio routine. In the real world, there are many ways to get a good cardio workout. You can jog, play sports and get chased by the police. In the gym cardio usually revolves around a handful of machines. There are the stair climbers or steppers, the elliptical trainers, tread mills, and bicycles. That's about it. A good cardio routine can last anywhere from 20 minutes to an hour and is really intensive. The problem is that when you are on a cardio machine, you do the same thing over and over. What I am trying to say is that for most of us cardio gets boring after about five minutes. Don't lie, you know what I am talking about. The best I have every heard about cardio is ‘I don't mind it.' In other words, I get really bored, but I will keep doing it cause it works.
Being bored is horrible. Being Bored is even worse when you know you have another 25 min left and the seconds crawl by like eons. So what gives. Why does cardio have to be so boring? I think it's a safety issue. In the real world if you go running or play soccer for example, you environment and all its inputs are constantly changing; you run by different scenery, you miss the shot on goal. These changing characteristics are what make the whole process fun. In the gym, however, since space is limited, you have to do your cardio rooted to one spot. Very little happens to your environment to elevate the boredom. Imagine though, if you could have all the excitement of a soccer game while sitting on a recumbent health cycle? At first you may think it's a great and fun idea. No more boring cardio! Think about it and it becomes a little terrifying. The sheer amount of stimuli hitting you from all angles, your mind would exhaust quickly and you would run the risk of injury (not to mention getting overwhelmed). That is why cardio machines are so boring. They design them to be boring so you don't hurt yourself. So when you climb up onto your favorite elliptical trainer, remember that its boring for a reason.
What can we do to make cardio more fun? Being new to the world of the gym I think I have some neat ideas to make cardio a more exciting activity. Ok that's a lie. I don't have any way to make cardio more exciting, but I do think there are some techniques to make the cardio experience pass more quickly, which, when you think about it, is the next best thing. I really try to distance my mind from my body. I try to unplug. I daydream, listen to loud music and think about my shopping list. For a whole week I designed a basement apartment for my house. It was quite the undertaking. Really focus on not thinking about time. Cover up the timer, know where the near by clocks are and avoid looking at them. Do what ever it takes to detach your self from the realm of the here and now. Remove yourself from our world governed by the second hand. Slip into recesses of your mind and tune out. While the cardio won't go away at least you can distract yourself. Cardio machines make cardio boring and boring cardio is hard to stick with. Take comfort in knowing that your body loves the attention of a good cardio workout.
