The Risks: Rollerblading Injuries

July 19th, 2009

Acquiring rollerblading injury from a sport is highly likely because, for one, the body consistently receives force and pressure, which at times, can be in greater amount than the body can normally handle. There are also times when the environmental condition to which an athlete is exposed presents potential dangers that are out of his control. Other times, his behavior and judgment abilities are overridden by compulsive actions.

The same is true for rollerbladers. Researches show that as rollerblading becomes highly popular, the more injuries are recorded. In several countries, particularly the United States, Australia, and Canada, injury cases grow in an alarming pace.

While rollerblading injuries are likely to be more apparent among children and adolescents, statistics reveals that older individuals are as equally predisposed to injuries. In fact, the Consumer Product Safety Commission recorded injuries among people aged 65 years and above. Additionally, a previous study reported that injuries among male skaters are more usual than female skaters. There is no concrete reason for this, although researchers account it to the fact that there are more male skaters than female.

Dislocation, fractures, strains, and sprains are the most common injuries among skaters. Twenty-five percent of injuries occur in the wrist area, with the wrist fracture as the most commonly reported case. The wrist is highly vulnerable as it receives much of the force during a fall, especially when skaters fall with outstretched arms. Other areas frequently injured are elbows, knees, and head, although head injuries are quite rare, constituting only 5% of the reported cases. However, head injuries appear to be life-threatening and can cause long-term consequences both physically and financially. Deaths are not common. In a study, 31 of the 36 cases of death are caused by collision with vehicles.

Rollerblading injuries are said to cause by inability to stop, loss of balance, uncontrollable speed, performing tricks, and obstacles and surface irregularities. However, any injury from such events can be prevented if the skater wears the recommended protective gears: wrist guards, helmet, elbow pads, and knee pads. The fact that protective gears can save a skater from potential dangers shouldn’t be overlooked. A study revealed that those who wear protective gears are less likely to acquire injuries as opposed to those who don’t.

Moreover, most of the injured skaters didn’t have proper and formal training. This, therefore, emphasizes the importance of taking lessons from a certified skating instructor. Nothing can substitute the benefit of learning from an expert who teaches skating techniques that include proper braking and falling, balancing skills, and road regulations.

Cross Training for Fitness and Fatloss

July 11th, 2009

The numbers on your scale do not indicate whether you are fit or fat. Far more significant than your total body weight is the composition of your body tissue. If a man’s fatty tissue is bigger than 14% up to 15% of his body mass, or if a woman’s is more than 20% to 22%, he or she is overweight, or more precisely, overfat.

A small amount of fat is needed for padding the internal organs and as insulation under the skin. Excess fat leads to such diseases as diabetes, gout, high blood pressure, coronary artery disease, and gallbladder problems. There are very few, very fat persons. The reason is that the fittest, not the fattest survive.

The problem now is focused on how to resolve the problem. The problem with most people who want to lose weight is that they have the propensity to concentrate more on getting those numbers lower than what they are seeing now. What happens next is that they strive harder to achieve a lower weight, according to the “ever reliable” result of the weighing scale.

It would be more important to think of the human body as a heat-exchange engine that works on the basic principles of energy physics. The caloric balance equals the total calorie intake minus the total calorie expenditure.

Some of the calories people ingest are used for basal metabolism. As people get old, their bodies require fewer calories for this basic upkeep. Some calories are excreted as waste products. Some go into “work metabolism,” the energy expenditure required for any physical activity.

Hence, if people take in more calories than are used by these functions, there is a definite caloric excess. By the laws of physics, energy is transformed rather than destroyed. In this case, each excess of 3,500 calories is changed into a pound of fat. If people want to reverse this process, they have to burn up 3,500 calories to lose a single pound.

Winning the War Against Fat

When you think of fighting fat with exercise, you probably think of hours of hard, sweaty exertion. If this is the case, then, you will not get any farther. This is because people who are so much into losing more by exerting more effort tend to get bored easily.

Why? Because experts contend that when people exert more effort than what they are capable of doing creates a tendency to develop weariness and ennui. Hence, they give up, stop doing their routine exercises, and end up sulking in the corner with a bag of chips that seems to have all the bad calories in this world.

Now, you might ask, "What should be done instead?" The answer: cross training.

After some intensive studies and experimentations, health experts were able to come up with the concept of incorporating cross training in order to overcome or break the monotony or dullness in an exercise program.

Cross training refers to the integration of diverse movements or activities into a person’s conventional exercise routine. The main purpose of incorporating cross training into an exercise program is to avoid overdoing excess muscle damages and to put a stop to an imminent boredom.

Three of the most commonly used activities whenever a person decides to engage into cross training are swimming, running, and cycling.

In cross training, distance is one way to extend your activity as your condition improves. For this reason, you need to traverse a measured distance.

If possible, swim the course and measure the distance. If you will be using a running track, such courses usually are a quarter-mile per lap for a complete circuit.

Cross training offers a variety of benefits for fitness and fatloss. It builds up the strength and endurance of the heart, lungs, and blood vessels. It has also some tranquilizing effect on the nerves, and it burns up calories as much as it makes your “losing weight” more bearable.

Cross training has three basic components:

1. Endurance exercises to condition the heart, lungs, and blood vessels and to induce relaxation. These begin with a careful planned walking and jogging regimen, depending on fitness level.

2. Exercises to strengthen the muscles, particularly those important to good posture. These include some activities that are selected to encourage some people who are already burnt out with a particular routine.

3. Exercises to improve joint mobility and prevent or relieve aches and pains. These consist of a series of static stretching positions that are safe and effective for most of the people who wish to try to lose some fat.

Indeed, cross training is a great way to modify the concept of exercising and losing fat without having to endure monotonous activities. In fact, the idea of exercising is to like what you are doing, hence, if you engage into cross training, you will be aware of it that you have already achieve your desired weight.

Boiled down, cross training is, certainly, one way of having fun.

Benefits of Fish Oil for Fitness and Health

July 9th, 2009

When the words oils and fats are mentioned, health-conscious individuals tend to run for cover. What they fail to realize is that there are good fats and bad fats. Complete avoidance of intake of oils and fats would actually be detrimental – rather than beneficial – to their health.

The Truth about Fish Oil
Essential fatty acids must always be part of our daily diet – without them, we take one step closer to our deaths. Essential fatty acids are divided into two families: omega-6 EFAs and omega-3 EFAS.

Although there are only very slight differences to distinguish the two groups of essential fatty acids from each other, studies have revealed that too much intake of omega-6 EFAs can lead to inflammation, blood clotting and tumor growth. The good news, however, is that the opposite is true for omega-3 EFAs. Omega-6 EFAs can be found in vegetable oils while omega-3 EFAs can be found in fish oils among other foods.

Omega-6 vs. Omega-3
Physicians and scientists are of the same opinion that the cause behind increasing cases of heart disease, hypertension or high blood pressure, obesity, diabetes, premature aging and certain kinds of cancer is none other than an imbalanced intake of omega-3 and omega-6 EFAs.

As mentioned earlier on, omega-6 EFAs can be found in vegetable oils. This includes but is not limited to corn oil and soy oil, both of which contains high amounts of linoleic acid. Omega-3 EFAs on the other hand can be found also in marine plankton and walnut and flaxseed oils. It should be significant to take note that fatty fish and fish oils contain eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), fatty acids that have been observed to provide many benefits to the human body. In the early 1970’s, a study on Greenland Eskimos have revealed that one of the major reasons why they rarely suffer from heart diseases is because of their high-fat diet (mainly composed of fish).

The two essential fatty acids, EPA and DHA, are also helpful in preventing atherosclerosis, heart attacks, depression and various forms of cancer. Fish oil supplemented food have also proven to be useful in treating illnesses like rheumatoid arthritis, diabetes, Raynaud’s disease and ulcerative colitis.

Other Benefits of Fish Oil
There are a lot more illnesses and situations in which intake of fish oil has proven to be significantly beneficial.

Making the Heart Healthier
The heart is inarguably one of the most important parts of our body and having an unhealthy heart means having to suffer a rather limited lifespan. Naturally, it’s in our best interests to keep our hearts happy and healthy and one way of doing that is eating food that contains fish oil.

In Athens, Greece, for instance, a study was made to show if there was a direct relationship between high fish diet and inflammation of blood vessels. The results revealed that those who ate more fish than the others had a lower level of C-reactive protein and interleukin-6, factors that are commonly used to measure likelihood of blood vessel inflammation. These benefits remained even when the various risks associated with high fish diet were taken into account.

Fish to Become Thin
In Perth, Australia, a study had revealed that fish consumption can be used against hypertension and obesity. Researchers of the UWA (University of Western Australia) have discovered that a weight-loss diet which includes a regular amount of fish consumption can be quite effective in reducing blood pressure and improving glucose tolerance.

Fish Oil to Combat Asthma
People suffering from respiratory problems like asthma tend to be perceived as unfit and unhealthy. They should now be pleased to learn that certain studies have revealed the benefits of fish oil for asthma-burdened-individuals. Statistics show that approximately 20 to 25% of children today suffer one form of asthma or another at a certain point in their lives. And certain evidence reveals a regular diet of food with high linoleic acid content as the reason behind it.

Researchers of UW (University of Wyoming) conducted a study by subjecting a number of children to a high-fish diet while others continued with their regular diet. Results revealed that the participants who ate more fish were less prone to asthma attacks and were able to breathe more easily as well.

Consult Your Nutritionist Now
Nothing is good when consumed or used excessively but complete avoidance of a particular food type is equally harmful as well. Ask your nutritionist for the right amount of fish intake for your age and health status.

Exercise and Hypertension

July 8th, 2009

It seems as though many Americans are living a life that leads to high blood pressure or hypertension. As people age, the situation gets worse. Nearly half of all older Americans have hypertension. This disease makes people five times more prone to strokes, three times more likely to have a heart attack, and two to three times more likely to experience a heart failure.

The problem with this disease is that nearly one third of the folks who have hypertension do not know it because they never feel any direct pain. But overtime the force of that pressure damages the inside surface of your blood vessels.

However, according to experts, hypertension is not predestined. Reducing salt intake, adopting a desirable dietary pattern losing weight and exercising can all help prevent hypertension.

Obviously, quitting bad habits and eating a low fat diet will help, but the most significant part that you can do is to exercise. And just as exercise strengthens and improves limb muscles, it also enhances the health of the heart muscles.

Heart and Exercise

The exercise stimulates the development of new connections between the impaired and the nearly normal blood vessels, so people who exercise had a better blood supply to all the muscle tissue of the heart.

The human heart basically, supply blood to an area of the heart damaged in a “myocardial infarction.” A heart attack is a condition, in which, the myocardium or the heart muscle does not get enough oxygen and other nutrients and so it begins to die.

For this reason and after a series of careful considerations, some researchers have observed that exercise can stimulate the development of these life saving detours in the heart. One study further showed that moderate exercise several times a week is more effective in building up these auxiliary pathways than extremely vigorous exercise done twice as often.

Such information has led some people to think of exercise as a panacea for heart disorders, a fail-safe protection against hypertension or death. That is not so. Even marathon runners that have suffered hypertension, and exercise cannot overcome combination of other risk factor.

What Causes Hypertension?

Sometimes abnormalities of the kidney are responsible. There is also a study wherein the researchers identified more common contributing factors such as heredity, obesity, and lack of physical activity. And so, what can be done to lower blood pressure and avoid the risk of developing hypertension? Again, exercise seems to be just what the doctor might order.

If you think that is what he will do, then, try to contemplate on this list and find some ways how you can incorporate these things into your lifestyle and start to live a life free from the possibilities of developing hypertension. But before you start following the systematic instructions, it would be better to review them first before getting into action.

1. See your doctor
Check with your doctor before beginning an exercise program. If you make any significant changes in your level of physical activity — particularly if those changes could make large and sudden demands on your circulatory system — check with your doctors again.

2. Take it slow

Start at a low, comfortable level of exertion and progress gradually. The program is designed in two stages to allow for a progressive increase in activity.

3. Know your limit

Determine your safety limit for exertion. Use some clues such as sleep problems or fatigue the day after a workout to check on whether you are overdoing it. Once identified, stay within it. Over-exercising is both dangerous and unnecessary.

4. Exercise regularly

You need to work out a minimum of three times a week and a maximum of five times a week to get the most benefit. Once you are in peak condition, a single workout a week can maintain the muscular benefits. However, cardiovascular fitness requires more frequent activity.

5. Exercise at a rate within your capacity

The optimum benefits for older exercisers are produced by exercise at 40% to 60% of capacity.

Indeed, weight loss through exercise is an excellent starting point if you wan tot prevent hypertension. Experts say that being overweight is linked to an increased risk of developing hypertension, and losing weight decreases the risk.
