Cycling health and fitness
Thursday, December 6, 2007 | | |People take three paths to good health: doctor, diet and exercise. Our path to the doctor's largest expense, 1035 billion in 1996, nearly 1/7th of gross national product. More than 60% of these visits involving drugs, and there were more than 70 million surgeries (source CDC). However, there are lower costs, trauma and tragedy if we had prevented many of these health problems. According to the American Medical Association, 60% of Americans are physically inactive. According to U.S. Surgeon General David Satcher, the number of people at risk of diabetes, heart disease, cancer and stroke is more and more, and 50% of Americans are overweight. He said that improving nutrition with 30 minutes of exercise five times a week could reduce cardiovascular disease and death by 50% and colorectal cancer by 40% (source CNN, June 11, 1999).
Unfortunately, those who decide to meet the health warnings tend to go over on nutrition and adopt the bad years. Rather than exotic nutrients, we need a diet consisting mainly of cereals, fruits and vegetables, with reduced amounts of meat and cheese. Rather than weightlifting, TV "aerobics" and from crisp, we need true aerobic exercises that help strengthen the heart, such as brisk walking, cycling, jogging, swimming, rollerblading, skating and skiing. The best exercise to change our sedentary habits is what we can and will do almost every day.
Cycling has several advantages compared to other years:
1. Cycling exercises the heart better than walking without hammering jogging.
2. You can ride a bicycle almost anywhere, at any time of year, and low cost.
3. Little or no time must be lost, as bike trip can be used to get to work, conducting courses, or enjoy the outdoors.
4. Commuting by bike reduces the pollution that causes asthma and bronchitis. A cyclist in common is also less exposed to air pollution as a car shuttle.
However, cycling involves some risk of injury which has been greatly exaggerated by fearmongers. Cycling has made similar risks to automobile travel. The British Medical Association has estimated that the health benefits of cycling outweigh the risks to twenty-one.
A very interesting question is what should get an aerobic exercise every day? Some medical authorities recommend as little as 20 minutes a day, three times a week, while others recommend 2000 Kcal, which would be at least four times that amount. Why the big difference? Well, most authorities agree more exercise the better in some indefinite, but many are afraid that if they wait too long, people will not exercise at all. Another reason for lowering the recommendation was due to damage caused by jogging, cycling a problem does not share. I fear that those requirements are very low to give people the false impression that they do not need more exercise than usual, mostly sedentary.
How much exercise do I recommend? I think that 45 minutes of bike six days a week (about 2000 kcal) keeps me feeling good, but not many, two hours a day keeps me very strong and control my weight, and six hours per day on my bike I feel like Superman after several weeks. We could say that lower amounts of exercise improved health and higher amounts improve his fitness. I would recommend a minumum of 45 minutes per day and a lot more than the bike as the weather permits. The cycling time will not be lost, in addition to having a good race, the cyclist will be more productive during the remaining time and live longer so.
