How Safe Are Mobile Phones?
by VikoJohns

Millions of people own a mobile phone these days, and ever since they have been around scientists question the fact of they are safe or not. Do they cause tumors, earaches, mercury poisoning? All these health risks are mentioned in every article I found. But nowhere could I find anything that was sure if mobiles did cause all of the above. This is where science fails us. The problem is that mobile phones are still too new to know the long-term effects on human. Mobile phones give of a radiation of radio frequency round 10MHz to 300Ghz. But so do other appliances. Why does mobiles especially get put in the picture of being hazardous? Soon it will be clear whether the radio frequency emissions from mobiles cause health effect.

Drivers who use there mobiles whilst driving are the only health risk that can be proven, the drivers get distracted and lose control over the vehicle. Technology invented something for this, hands-free sets. But now the question is do those hands free sets really solve the problem? Researchers now are looking at if the hands free sets dont cause other problems. A report from the magazine which? said that hands free kits raised levels if radiation to the head from mobile phones by up to three and a half times. The consumer association immediately stressed that it had done no research into this whether this radiation could cause damage to the brain. That just proves that whenever there has been research a report is released to prove that research wrong. Probably is done not to cause any chaos.

Mobiles are said to cause brain tumors, they say this because there was found to be more tumors of the same kind amongst mobile phone users. Mobiles cause memory loss, radiation sickness. Mobiles can disturb your sleep pattern, according to the researchers from the university of Zurich, mobile phones increases brain activity during our sleep. A really strange result of the use of mobile phones is that mobile phones can release the poisonous mercury from fillings causing brain damage, scientist say this is due to the electrical fields given off by mobile phones can activate the mercury, giving off a gas. The fumes attach the nervous system causing conditions from depression, asthma to Alzheimers disease and multiple sclerosis.

Some studies have suggested links between Radio frequency radiation and lymphoma, microwaves and memory loss, mobile phone use and a rare type of brain cancer, mobile phone radiation and DNA destruction, and mobile phone use and damaged scalp nerves

The world health Organization has asked for more and more research, but all the time and money spent results in the same answer over and over again. When the press publishes such reports, that these studies came up without result the scientists will report that their data suggest it is unlikely mobile phones cause cancer, perhaps even highly unlikely. They will admit that they cannot rule out and effect. This may satisfy the public, until a counter report is published. How ever if these studies can identify a mechanism that causes the brain tumors, we have a real public health threat on our hands and the authorities are put into action. End of fear is when we stop using our mobiles or we stop using them in a way that could be dangerous

It seems one cant enjoy technology any more without its faithful side effects, suffering a slow death. All these risks are know to effect the youth more. If that is known why do mobile phone Companys make their phones with Disney covers and with other accessories to make mobiles more popular to the youth. Even scarier is the thought that those companies may not be telling us the whole truth. If mobile phones are questioned now, when will it be stopped? Will microwaves, electric blankets, or televisions be next?

Technology is doing every thing it can to improve the mobile phones. To try and make the radiation that is sent out as harmless as possible, in the mean time before the technological level is high enough to do so, experts have made reports to reduce the amount of radiation. They recommend things like:

Cut down on time spent using the mobile phone

Use a mobile phone where the antenna is mounted outside a car

Keep mobile at a short distance from the ear

Factors that can effect how people perceive how risky new technology is that no one really knows what the long-term effects are, and until that is certain people will still be researching new possibilities. If no immediate link is put between all the risks and the real effect of mobile phones on humans, then there will be no problem in buying mobiles. The problem is that without knowing the really risk manufactures cannot develop mobiles to being safer, so many people are exposed to harmful radiation without that individual knowing. As we know from the past only big helpful research starts when a tragedy hits. In other words, who knows? There is no proof that mobile phones are a health risk, or that they are a hundred percent safe. Some say the danger does not end until after ten minutes after hanging up because the user is still processing the conversation.

Low-Fat Diets Don’t Work

October 28th, 2008 by admin

Fifty years ago, only a small percentage of the population had problems with their weight. Now it%26#8217;s an epidemic! All this has happened while we cut back from 40 to around 32 percent fat as a percentage of our diet.

Are you still caught up in the low-fat mantra of the past couple decades? Do you think you can%26#8217;t eat much fat if you are trying to lose weight? These ideas are still so prevalent in our media and in the low-fat products you see everywhere that it%26#8217;s no wonder you may still believe this. In fact, even many doctors still believe this.

However, according to the U.S. Center for Disease Control, in 1999-2000, an estimated 64 percent of adults in the United States were either obese or overweight. That%26#8217;s almost two thirds of the adult population, and one third of our children are now overweight as well. In the past 30 years, the number of overweight children has doubled. In just the past decade, the number of obese people in the U.S. has gone up two and one half times.

Fifty years ago, only a small percentage of the population had problems with their weight. Now it%26#8217;s an epidemic! All this has happened while we cut back from 40 to around 32 percent fat as a percentage of our diet.

Low-fat diets not only don%26#8217;t work, but they%26#8217;re not healthy, not natural, and they tend to promote weight gain! Research confirms this statement. The famous Framingham Study that started in 1948 is still going on, and it shows that the more saturated fat, the more calories, and the more cholesterol a person ate, the lower their serum cholesterol! The results also show that the more fat they ate, the less they weighed!

So, we are eating less fat as a nation, but are gaining weight. There are a number of reasons for this. One is that since fat gives foods much of their flavor, when manufacturers cut out the fat, they add sugar, MSG and other chemicals to the food to enhance the taste. These can all have adverse effects on both our weight and our health.

Saturated Fats Are Necessary for Good Health

Many of us, doctors and laypeople alike, were taught that red meat and fat, and especially saturated fats, are to be avoided. We still hear that they cause all sorts of problems, including high cholesterol, heart disease and weight gain. However, if you carefully study the research, you will see that it shows the opposite to be true. Saturated fat is a vital nutrient and is necessary for good health.

In order for your body to properly use fat-soluble vitamins, you need to have the fat in your foods. Calcium, too, needs fats for proper absorption. So it%26#8217;s important to use full

-fat dairy products and put butter and cream on your calcium-rich leafy green and other vegetables and eat salad with oil-based dressings. If you eat this way, you will increase your absorption of the vitamins and minerals contained in those salads and other vegetables.

While we Americans have been lowering the amount of fat in our diets, especially saturated fats like animal meats, butter, lard, coconut oil and full-fat dairy products, not only have obesity rates skyrocketed, like previously discussed, but heart disease rates have also increased. A wealth of research points to vegetable oils, sugar, especially high-fructose corn syrup, and refined grains as a major cause of obesity, and to trans-fats, and vegetable oils and shortening as a major cause of heart disease.

FACT: By 1950, butter consumption had dropped from 18 lbs per person per year to just over 10. FACT: Heart disease caused probably no more than 10 percent of US deaths prior to the 1920%26#8217;s. By the 1950%26#8217;s it had risen to 30 percent or more.

According to Dr. Ron Rosedale, when you eat lots of carbohydrates, especially simple carbohydrates like sugar and white flour products, your body converts them to sugar and then burns that sugar instead of burning fat. Saturated fats act as a carrier for the fat soluble vitamins A, D, E and K. When the fat is removed from foods in our diet, many of these vitamins are also removed, and our absorption of these vitamins also goes way down.

Saturated fats protect the liver from alcohol, drugs and other toxins. Saturated fats also support the immune system, which helps keep you from getting sick. Saturated fats are needed for correct bone development and in order to prevent osteoporosis. A high level of fat in the diet needs to be saturated in order for the body to properly utilize calcium. This means that a low-fat diet with plenty of calcium and/or calcium supplements is not necessarily going to prevent osteoporosis, and this is seen today in the high rates of osteoporosis.

Saturated fatty acids are necessary for proper functioning of all our cell membranes. They give our cells the firmness necessary to maintain structural integrity. All your cells and organs, especially the brain, need saturated fats in order to function properly. So stop worrying about eating low fat. Add real old fashioned fats back into your diet like cream and butter and watch the excess pounds slowly disappear.

Buying A Treadmill — What You Need To Know

October 28th, 2008 by admin

Of all the various types of home exercise equipment that have come and gone, the home exercise treadmill has lasted throughout the years. Treadmills are simple to use. There are many competing models of treadmills to choose between.

Of all the various types of home exercise equipment that have come and gone, the home exercise treadmill has lasted throughout the years. Treadmills are simple to use. There are many competing models of treadmills to choose between.

Treadmills can have an AC or a DC powered motor. A few treadmill models are powered by the user rather than a motor. With treadmills you need to watch out for the impact involved when your feet hit the belt; your body absorbs up to two and a half times your body weight.

The console indicates belt speed and other factors, such as heart rate, mph, distance, etc. Many of the treadmills available have the ability to add an incline to your workout to duplicate running or walking uphill, therefore increasing the intensity of a workout. Safety features on a treadmill are especially important if you plan to work out alone or if you have small children who might accidentally start up the treadmill.

One of the key things to remember is that the larger motors tend to run cooler and usually require less repair and maintenance. The deck is the belt area on which actual running, jogging and walking take place. Notice that some treadmill heart rate monitors clip onto an ear or, for more accurate readings, strap on to the chest.

The newest models of treadmills come with many extra features. The more expensive treadmill models will also offer a selection of preprogrammed exercise routines.

A noisy treadmill can upset other family members or roommates and even your neighbors if you live in an apartment or condo. Consider the cost of maintaining your treadmill as well. Check out the level of noise that a treadmill makes during operation; something that many buyers overlook.

A major consideration when buying a treadmill is the construction of the machine. Commercial club treadmills are reliable and well constructed; do l

ook into a home version. Any treadmill with a belt that causes jerky movements while you walk or run should be avoided.

Do your research; treadmills are an important investment, regardless of the price, and if it%26#8217;s not right for you, you don%26#8217;t want to find out after you%26#8217;ve set the treadmill up at home. When buying a treadmill, the best savings will be for an online purchase, generally saving up to 45% over brick and mortar stores. The motor on a treadmill is also important to consider.

Probably the most important thing to look for in a treadmill is how sturdy it is. To make sure that your treadmill is sturdy and comfortable and doesn%26#8217;t operate noisily, step on it and test it out before you buy. One indication of the likely longevity of any treadmill is to check out the length of the manufacturer%26#8217;s warranty; the longer the better. Noise from the smallest repetitive sound can drive you nuts over a period of time and provide you with one more reason not to exercise.

If you have severe leg conditions, a treadmill may not be the best choice of home exercise equipment for you. Better quality treadmills provide excellent cushioning to limit the impact on knees, ankles, hips and lower backs.

Whether you use a treadmill to walk, jog or run, the units are very effective at burning calories, raising heart rate and developing aerobic capacity. Lack of wind resistance makes running on a treadmill slightly easier than it would otherwise be on an equal elevation grade outdoors.

And remember, home exercise treadmills are a large investment financially and in your fitness and much thought and preparation should go into the purchase of any new treadmill. Choosing the best treadmill is easier than ever. Take time to do your research, the same way you would any major purchase and buying a treadmill won%26#8217;t be difficult.

Walking: Safest, Simplest, Best Form of Exercise by La Rue Briggs

October 28th, 2008 by admin

For the majority of people seeking to improve their health and fitness, walking is the safest, simplest, best form of exercise. Walking has a variety of valuable physical benefits such as assisting in making the heart and lungs perform more efficiently, keeping blood pressure properly regulated, decreasing the level of artery-clogging blood fats while increasing the level of high-density lipoproteins (the “good” HDL cholesterol), reducing the odds of developing heart disease, firming and shaping up muscles, relieving tension and raising one’s energy level. Walking also aids in weight loss, strengthening bones, and may serve to halt or lessen the degree of severity of osteoporosis (the bone-thinning disease that commonly occurs in older, inactive women but sometimes strikes younger women and, to a lesser extent, men). Walking is an activity that one can do practically anywhere at anytime, alone or with a companion.

Lately, walking has become the exercise of choice for millions of Americans trying to get and stay fit. Throughout the U.S., walkers attired in various styles of workout apparel, many wearing fanny packs around their waists, can be seen daily dotting the landscape as they energetically move back and forth.

When compared with that other popular aerobic exercise, jogging, walking causes less shock to the lower back, hips, knees, ankles and feet. The force of jogging can subject joints to impacts three to five times a person’s body weight each step. With walking, however, one foot always remains on the ground, thus the shifting of body weight is more fluid. For this reason, a walker lands with only one to one and a half times the force of his body weight each step.

True, walking does take a mite longer to do than jogging. But you can burn nearly as many calories (e.g., walking at a 15-minute-a-mile pace you can burn approximately 100 calories per mile, whereas jogging at a 10-minute-a-mile pace you burn roughly 20 calories more) and get nearly as good a workout by walking that mile as you can by jogging, bicycling or swimming at a moderate pace. The heart doesn’t make a distinction between any of these activities; its job is solely to deliver the blood and oxygen needed to the working muscles.

The heart muscle, like all the other muscles of one’s frame, needs to be challenged with exercise to keep it strong enough to receive and pump blood through the arteries and veins to the rest of the body. A heart that has developed strength and endurance through an aerobic undertaking such as walking has not only a lower resting and working rate of speed (i.e., performs its function using fewer beats) but also sends out more blood with each beat.

Moreover, walking enables a person to see the world in which he or she lives in greater detail. Scenery such as buildings, houses, trees, flowers and lawns become more noticeable when one is on a walk.

Walking also frees the mind for creative thought. Many walkers possess a belief similar to that of Henry David Thoreau, who once said, “Methinks that the moment my legs begin to move, my thoughts begin to flow.” Akin to Thoreau, these walkers state that they do their most productive thinking while walking and are better able to solve complex problems.

Nevertheless, although walking is a low-impact exercise that’s less strenuous and less harmful than jogging, beginning walkers still should pay attention to taking those precautionary measures that will help protect them from injury.

In particular, along with putting on comfortable, unbinding clothes, they should wear lightweight, properly fitting walking shoes with enough support and cushioning in the heel and arch to minimize the pressure on their joints; being mindful of the calf muscles as well as the muscles at the front and the back of the thighs, they should do about 10 minutes of warm-up exercises and 10 minutes of warm-down exercises consisting of static (no bouncing) stretches - holding each stretch for 20 to 30 seconds, before and after walking to prevent damage to their muscles and tendons; and, they should attempt to walk on a flat cushioned surface to reduce the strain on their legs and feet. By following these precautionary measures, beginning walkers are less likely to get injured and require days or weeks of non-participation in exercise in order to recuperate.

Concerning form and technique, it’s best when walking to keep the body erect, head up, eyes looking straight ahead, shoulders down, buttocks tucked in and arms at waist level. Specifically, you should bend the arms at the elbows (at a right angle), with the elbows held out a bit from the sides and the arms pumping alternately from front to back with the stride. Try not to swing the hips from side to side as you walk. Each foot should land under the torso, almost flat and toward the heel. A short, heel-toe stride is recommended for walking by most authorities.

Perhaps more importantly, your walking pace should be one in which you are able to talk without becoming winded, without panting and gasping for air. This especially applies to those people just getting back into exercise after a two or three decades lay off.

Walking is so natural, so automatic that a lot of people tend to overlook its potential as exercise. One can walk at a brisk stroll, a rapid gait, or anywhere in between. Any of these speeds can aid walkers in reaping many of the benefits that come from working out.

To take a single instance, one of these benefits is: a delaying of the aging process. Recent medical research reports that millions of us cease to engage in activities that are physically demanding as we grow older; however, this same study says that involvement in such a rejuvenating activity as exercise can help to preserve our ability to carry out daily chores with relative ease as well as help to stave off the degenerative effects of aging. Even a moderate exercise program that’s done on a regular basis can promote better physical and mental health.

The widely held belief that exercising has to be a painful endeavor in order to create a favorable outcome is false. In reality, being consistent and persistent are much more essential to making beneficial improvements than how much pain you can endure during a workout.

Although, at the outset the body may rebel against your attempts to whip it into shape and leave you tired, stiff and sore after workouts. But this unpleasant fact of exercising is tempered by realizing that these minor discomforts are temporary. Once you become accustomed to working out regularly, exercising vigorously will be easier to do, and the minor discomforts will all but cease to exist.

Now, in reference to world-class Olympic athletes trying to achieve their lofty objectives of winning gold medals and other awards, learning to push themselves beyond the manifold barriers that stand in the way of victory is a relevant concept. But it’s an immaterial concept with regard to normal body conditioning. Besides feeling and looking great, here, one’s focus is on sound internal health, physical strength and a long, productive life.

All the same, even though walking at a tortoise-like pace will get you from point A to point B without shattering your laid-back image and producing sweat, to elevate your heart rate to a cardiovascular fitness level you’re going to have to expend some energy in your walking motion. Yet, with no more than a spirited arm swing and an accelerated stride, you can attain a significantly higher heart rate.

In fact, to make a walking program an effective one, many doctors and trainers recommend that walkers walk for at least 30 minutes a minimum of three times a week while maintaining a certain target heart rate.

However, if your heart rate overly exceeds the pre-determined target heart rate, it could mean that too much stress is being placed on the body. Conversely, if your heart rate falls well below the pre-determined target heart rate, your pace won’t be sufficient for a good aerobic workout. Consequently, it is very important that walkers are knowledgeable about and are able to correctly estimate their exercising heart rates.

A simple way to figure out your target heart rate is to take the number 220 and subtract your age. The remainder represents your maximum heart rate. Your goal now is to begin exercising at some percentage of this number. Typically, for people who haven’t taken part in vigorous exercise for a while, the percentage of your maximum heart rate will be around 55 to 65 percent; and for people who are hale and hearty, the percentage of your maximum heart rate will be around 70 to 80 percent.

As an example, if you’re 40 years old, you would subtract that from 220 and find your maximum heart rate is 180. Assuming you’re one of the hale and hearty people, you would then multiply 180 by .70 and get 126.00. Thus, you should be walking at a pace that will cause your heart to beat at a rate of 126 to 135 beats a minute.

For a person having difficulty taking his or her exercising heart rate, the easiest places to count it are the radial artery on the wrist and the carotid artery on the side of the neck. Use the first and second fingers of the hand and place them on the thumb side of your wrist or place these same two fingers on the opposite side of your neck. Take your pulse for 15 seconds, then multiply by four.

After successfully completing at least eight weeks of diligent, progressively vigorous, injury-free walking, you may now consider making your training regimen a little tougher.

Through walking, you have made your leg muscles stronger, yet to this point your upper body has been virtually ignored. By carrying one to five pound hand weights while walking, you will not only tone up your arms but heighten the intensity of your workout as well. Furthermore, walking up and down hills, walking in sand at the beach, and ascending and descending flights of stairs are some other ways to challenge and strengthen the muscles of the feet and legs as well as the heart and lungs. Additionally, you will be pleased to know that by increasing your efforts you’ll also be able to burn up more of those fat grams that produce a large number of calories and, as a result, extra body weight.

Later on, when you’ve become really fit, “speed walking” (i.e., walking at a 12-minute-a-mile pace) can be the next mountain to climb in your ambulatory adventure. Though speed walkers may look peculiar as they move, speed-walking is actually a much greater challenge than jogging at the same speed because the muscles must work harder to hold the fast-walking pace without breaking into a jog.

Nonetheless, since one’s target heart rate and the duration and intensity of a walking program varies according to age, weight, hereditary background and other factors, you first should go to a medical professional for a checkup and more detailed information regarding the most appropriate walking program for you.

Fitness, Eat Yourself Fitter

October 22nd, 2008 by admin

Don’t Starve Yourself Cutting kilojoules may help the kilograms drop off, but it can also leave you feeling lethargic and weak, hindering your efforts in the gym. Worse, your body can end up hoarding instead of burning fat. A sudden drop in kilojoules is interpreted by the body as a signal to conserve energy because starvation could be imminent. The body goes into survival mode and the rate at which it burns energy slows. To compensate for the low kilojoule intake, it starts to break down precious lean-muscle tissue for energy - bad news if you want a sculpted-body look. To lose weight, cut your kilojoule intake by no more than 15%. Conquer your Carb Fear Sweets and cakes may sound like a fit girl’s no-no but if you work out daily, sweet treats can sit happily on your menu. Eating a high-GI snack, such as a slice of ginger loaf, immediately after your workout will deliver fast-release carbs to your fuel-depleted muscles. That snack will be converted to glycogen (muscle fuel) one-and-a-half times faster than normal. It doesn’t matter whether you opt for solid or liquid nutrition; the important thing is to consume the carbs within two hours of exercising. But don’t overdo it. Don’t Pile on the Protein It’s tempting to think that a high-protein diet will boost your performance in the gym and make you stronger, but the truth is you need only a little more protein than your non-active friends. Regular exercisers need about 1,2g to 1,4g per kg of body weight daily, depending on their sport and how hard they work out. (That’s 72g to 84g if you weigh 60kg.) Most people get sufficient protein from their daily diet. Two or three daily portions (each the size of a deck of cards) of lean meat, fish, poultry, beans, lentils or dairy products will meet your needs. Serious bodybuilders (who need up to 1,8g of protein per kg of body weight daily) and vegans (who exclude meat and dairy products) may need protein drinks or bars to help make up the shortfall in their diet. Be a GI Jane Tuck into a bowl of porridge before your morning workout. Studies found that athletes who ate a low-GI meal (foods that produce a gradual rise in blood sugar levels) two to four hours before exercise were able to keep going for longer than those who ate a high-GI meal. According to a study at Loughborough University in the UK, runners who ate a low GI meal three hours before exercise burnt more fat than those who ate a high-GI meal with the same amount of carbs. For a healthy, high-powered snack, try fruit with yoghurt, Weetbix with milk or a baked potato with cheese. Watch the Water You’re probably familiar with the advice to drink lots of water when you’re exercising but, following a few cases of hyponatraemia (a dangerous condition caused by drinking too much water) among marathon runners, sports-medicine experts now caution against over hydrating yourself in events lasting more than four hours. Drinking water constantly may dilute your blood, causing sodium levels to fall. Although rare, hyponatraemia is potentially fatal. The American College of Sports Medicine recommends drinking only when you’re thirsty. You shouldn’t drink so much that you take in more fluid than you lose. Sports drinks are better than water if you’re running a marathon - their sodium content will prevent hyponatraemia. Take a Snack Whether you exercise early in the day or late in the evening, you need to refuel your muscles within a couple of hours. Skipping a post-workout snack or meal will delay your recovery and leave you feeling sluggish the next day. Provided you don’t overeat, these kilojoules will not be turned into fat. After working out, have a drink (water, diluted juice or a sports drink) immediately, then a snack (even if you’ve worked out after supper) or a light meal within two hours. Try a smoothie, a milkshake, a jacket potato with tuna or cottage cheese or a chicken-and-rice salad. Include this snack in your daily kilojoule total and plan ahead to ensure you have the right sort of foods on hand. Never Run on Empty It’s a myth that training on an empty stomach will help you shed weight faster. The theory behind it is that your blood-sugar levels are low when you’re in a fasting state, which prompts the body to burn fat. The problem is you’ll tire sooner, so your total kilojoule burn is likely to be less than if you had eaten a light snack two to four hours before exercise. You’ll burn more kilojoules if you eat before you work out. When you don’t eat before your workout, many of the reasons for exercising - conditioning, fitness, building muscle and losing weight - go out of the window. That’s because your body turns to muscle protein for fuel when it doesn’t have enough carbohydrates to burn. Avoid Goo on the Go Energy gels (concentrated syrupy carbs designed to slip down your throat when you’re on the run) may promise instant energy but they can end up as a mass of goo in your stomach if you don’t drink enough water with them. You’ll need to swig 350ml of water per 25g sachet. Energy bars and gels are not essential if you exercise for an hour or less. Having a snack - such as dried fruit or a bagel with peanut butter - an hour or two before you train, as well as being properly hydrated at the start, should sustain you for workouts of up to an hour. Make Friends with Fat Extremely low-fat diets won’t make you leaner in the long term. There may also be adverse side effects, such as poor vitamin and mineral absorption, and reduced immune responses. The American Dietetic Association and American College of Sports Medicine recommend that regular exercisers consume 20% to 25% of their daily kilojoules in the form of fat. So, if you eat 9 000kJ a day, you should aim to eat 56g to 69g of fat. Omega-3 fatty acids are beneficial if you exercise, as they boost fat metabolism by lowering the levels of insulin. Eat at least one portion of oily fish a week, or a tablespoon of walnuts, pumpkin seeds or flaxseed oil daily. Don’t Pop Pills If you regularly work out intensively, you’ll need more vitamins and minerals than the RDA, so consider taking a multivitamin supplement. But be wary of other sports supplements: ephedrine-based fat-burners, for example, may contain substances that cause diarrhoea and headaches. A 2001 survey funded by the International Olympic Committee of 634 non-hormonal nutritional supplements found that up to 20% were contaminated with banned substances, including steroids. The British Olympic Association and UK Sport advise athletes not to take any supplements. Sandra Prior runs her own bodybuilding website at http://bodybuild.rr.nu.

How To Choose And Buy Your Treadmill

October 22nd, 2008 by admin

Consider a day when leaving home is not an option as it is probably too late or just snowing outside. You are missing out on your regular regimen in the gym and you just have to burn off those extra calories you had piled on the day before.

Consider a day when leaving home is not an option as it is probably too late or just snowing outside. You are missing out on your regular regimen in the gym and you just have to burn off those extra calories you had piled on the day before. The utility of having a treadmill at home has now become obvious to you for a useful home workout. But buying one needs careful scrutiny as it has to suit both your pocket and fitness schedule.

The choice often varies between an automatic treadmill and a manual one. Remember that when you step onto the wide belt resting over a flat body and a couple of rollers, your feet supports two and a half times the weight of your body. So it is an imperative to examine the load involved.

When considering the purchase of a treadmill, carefully notice the tenacity of the deck or the belt area as that is where your basic exercise is done whether it is running, jogging or just plain walks. Attractive extra features like cup holders, CD players and other electronic equipments like built-in fans are hardly essential in this respect.

Customized fitness routines might be available with treadmills now days. They might have built-in speedometers, indicating belt speed, mph and distance covered along with heart rate, with display options on the monitor. Such functions are carried out without wire connections. But the price range for such treadmills will be higher than usual.

Extra features like heart monitors and default safety options like automatic stoppage of the belt on slipping, adds to the safe and hassle free usage of the treadmill. To increase or decrease intensity of workouts instantaneously (e.g. Changing inclination of the deck) cheaper models are a hindrance as the entire shift has to be done manually by rotating knobs, etc. which can be very disturbing in the course of a workout.

Greater warranty periods offered by manufacturers are obviously indicative of the tenacity of the treadmill. Long w

alking, as well as running, regimens require sturdy and thus, more expensive treadmills. Thus, before purchase, test the machines in the store.

Built-in heart rate monitors serve as cardiograms and provide important health information. Also include low levels of noise made by the treadmills in your parameters as noise is an impediment to exercise. After choosing the appropriate features, check price catalogues online to choose the cheapest option.

It is, of course, easier to buy a treadmill if you%26#8217;ve tried out one in a gym and think it is to your liking. Try to find one similar for your home. Online buys are often cheaper and one can save up to 45% over store buys. Maintenance is basically about using lubricants and cleaners to smoothen the run.

Take into account family members who would like to use the home treadmill. Accordingly, assess your power requirements for the treadmill. Ideally, buy a treadmill equipped with a motor that delivers 1.5-3 horsepower continuously.

Among the various advantages of possessing a home treadmill are of burning fat, enhancing lung capacity, and facilitating heart rate functions. Also, an important consideration is regularization of your exercise schedule due to increased availability. With the variety of programs on offer, it is easier to use a treadmill in multiple ways.

Look beyond the advertisements and analyze your choice of features and match cost requirements, keeping in mind cost of maintenance. Go for the buy now, carefully comparing offline and online prices. There are ratings and reviews of treadmills that come in handy to make a well-informed decision to buy the cheapest and the most effective home treadmill.

One consideration to make would be consulting your doctor or trainer before beginning to use the treadmill as they exert great stress on your hip and knee joints.

It is, though, very important to use a treadmill to keep fit and healthy and keep those joints in motion.

Finding The Perfect Treadmill For You

The word treadmill originally designated a type of mill which was operated by a person treading steps of a wheel to grind grain. With treadmills you need to watch out for the impact involved when your feet hit the belt; your body abosorbs up to two and a half times your body weight. Some treadmills fold up for easy storage which makes them an ideal choice for those with limited space in a small apartment, small house or condo.

Features such as extra cup holders, built-in fans, CD players and other electronic gizmos may be handy but not essential for you to get an ideal workout. Notice that some treadmill heart rate monitors clip onto an ear or, for more accurate readings, strap on to the chest. One of the key things to remember is that the larger motors tend to run cooler and usually require less repair and maintenance.

Adjustable inclines let you vary the steepness of a hill. Many of the treadmills available have the ability to add an incline to your workout to duplicate running or walking uphill, therefore increasing the intensity of a workout.

Some excellent features, like heart monitors and safety keys that automatically stop the treadmill if you slip, will contribute to the enjoyment and safety of your treadmill workout or help add motivation. The newest models of treadmills come with many extra features. A heart rate monitor is another useful feature to look for.

Most manufacturers of commercial treadmills found in gyms and health clubs also produce home versions. If you plan to use a treadmill purely for walking you are not likely to need an expensive top-of-the-line machine. You%26#8217

;ll probably want to buy a unit with a motor that delivers 1.5 to 3 continuous horsepower.

If you%26#8217;re looking for a heavy-duty treadmill that can withstand running as well as walking, be prepared to spend more money. Noise from the smallest repetitive sound can drive you nuts over a period of time and provide you with one more reason not to exercise. Probably the most important thing to look for in a treadmill is how sturdy it is.

If you can afford to buy a treadmill with a heart rate monitor, it%26#8217;ll be a good invesrment in your health. Make sure to check out the warranty, this is very important. Buying a treadmill online will save you both time and money.

The more incline variation offered in a treadmill unit, the more expensive the model will be. Once you%26#8217;ve decided on the treadmill that you think is right for you, make sure to compare prices online.

It%26#8217;s best to get a treadmill that has a warranty that lasts for at least a year. Keep in mind that what feels right to you may not accommodate others around you as comfortably.

Running or walking on a treadmill can be an effective way to workout compared to other complex cardiovascular exercises. Make sure to see your doctor or naturopathic doctor before you start any new fitness or exercise program.

Walking, whether on a treadmill or not, is one of the best approaches anyone can take toward fitness. The more programs the treadmill offers the more you can vary your workout and then more likely you%26#8217;ll continue exercising on a regular basis.

For most people buying a home exercise treadmill is going to be a major investment. Choosing the best treadmill is easier than ever. Take time to do your research, the same way you would any major purchase and buying a treadmill won%26#8217;t be difficult.
