Why Do You Skate?, I always knew I was doing somthing good for my body by skating, besides having fun. Now when someone asks me, "What's so great about skating?" Jason Stewart has given me the words to express the fun. Thank you Jason for the opportunity to reprint your Paper. |
Why in-line skate? It is a simple question. One which has many answers. The biggest one being fun. You dont see runners having fun. Theyre huffing and puffing with their bouncing up and down. Skaters just cruise by smile and wave. The second is health. This report is on the health benefits in-line skating has on the human body. You cant very well do a report on fun now can you? It is even arguable that in-line skating is the most health beneficial physical sport in practice. Back to the original question. Why in-line skate? Because in-line skating provides the most
important components of a good all-around fitness program.
Cardiovascular or cardio respiratory fitness (endurance), muscular fitness
(muscular strength and muscular endurance), body composition, and flexibility. And remember, in-line skating isnt a source of fitness for adults only. In-line skating may have special significance in terms of fitness benefits it can have for children. According to several studies, American Children, as a group, are not as fit as they once were. Children are spending more time participating in passive activities such as watching television or using the computer and less time participating in sports. According to the Sporting Goods Manufacturers Association (SGMA), in-line skating is the most popular outdoor recreational sport among American children ages 6-17. Cardiovascular fitness (also known as cardio
respiratory fitness or aerobic fitness) by definition is the measure of the bodys
ability to do work (exercise). When you exercise, blood is pumped by the heart to the
working muscles. This blood has had oxygen put in it by the lungs. The muscles use up some
of the oxygen and send the rest back to the lungs for more. As you get more and more fit,
your muscles become able to use more and more oxygen in the blood, which in turn, allows
you to do more work. The more work you are able to do, the more blood your heart can pump
and so on in the upward spiral of fitness. Muscular strength is a measure of the ability of a
muscle or a group of muscles to perform work against a significant resistance. As we get
older, our strength declines steadily unless we engage in some type of physical activity.
The repetitive, low-impact movements of in-line skating can provide sufficient leg
exercise to maintain muscular strength. In addition, the unique bent-knee
position used during the glide phase forces the legs to support all of the body weight in
a position in which they dont typically support much weight. This increases strength
through a greater range of motion than do sports such as cycling or running. The increased
strength you gain not only helps your skating but can cross over to other sports as well.
The movement during a classic skating stroke not only extends the leg, as in
walking or cycling, but also pushes the leg to the outside of the body, abducting
(extending away from the center of the main axis) the leg at the hip. This leg abduction
and the ensuing leg adduction, or returning the leg toward the middle of the body, use
muscles not recruited during the linear (straight line) activities of walking or cycling.
These muscles located on the inner thigh and on the gluteal region become stronger
as a result of skating. The strengthening both assists in skating and minimizes the risk
of injury when performing other activities, since those muscles will be less likely to be
overworked. Muscular endurance is the ability of a muscle or a
group of muscles to repetitively perform a task without experiencing undue fatigue.
Due to the unique biomechanics of the sport, the quadriceps muscles of the thighs remain
contracted for an extended period during each stroke cycle. This constant workload
makes it necessary for the leg muscles to develop endurance. Increasing the duration of
your skate workouts will enhance your muscular endurance. ( as discussed earlier in
the paper through cardiovascular fitness). Body
Composition. Body weight alone is not an indicator of fitness level or health, the
composition of the body (fat mass and lean mass) is just important-or even more important-
in many people. Fat mass, as the name implies, is simply the amount of the body that is
composed of fat, while lean, or fat free mass, is the balance of the body weight, meaning
everything else. Now here is an interesting little factoid that many fitness gurus will be interested to learn. you wont necessarily be burning only fat when you expend calories. You can also be burning carbohydrate and protein. Generally, lower-intensity exercises (like skating!) get a larger percentage of their calorie burning from fats, while higher-intensity exercises get a larger percentage from carbohydrates. So to put it simply you can do a seemingly more fun and easier activity, skating, for a longer period of time and burn more fat calories than your carbos and proteins. Easier work for more fat calories burned? Sounds like the perfect diet! But wait, theres more. Being that you can burn more fat calories, it sounds to me like you can eat whatever you want and burn more calories having fun rather than working hard. It is the perfect diet!Flexibility, the degree to which joints can be put
through a range of motion, can be enhanced through in-line skating. The distinctive
lateral leg action (which has been noted as not present in running or cycling) of in-line
skating requires a certain degree of flexibility of the inner thigh muscles, so as you
improve your technique, your inner thigh muscles will be stretched farther during each
stroke. In-line skating as a form of exercise is as beneficial as running or cycling. According to Dr Carl Foster, associate professor of medicine at the university of Wisconsin Medical School and coordinator of sports medicine and sports science for the United States Speed Skating Team. In-line skating strides work leg muscles for
longer periods of time than running strides or cycling crank cycles. In-line
skating creates higher muscular activity levels for hips, thighs and shins than running or
cycling In-line skating produces less than half the impact shock to joints that running
does. This is most important. In-line skating, when compared to running causes less than 50 percent of the impact shock to joints, according to a recent study conducted by the University of Massachusetts, thus demonstrating that inline skating is less harmful to joints than the higher impact sport of running. In-line skating burns as many calories as running. It has also been stated and proven that skating burns more calories than running or cycling. Interval skating, (alternating one minute of hard skating in a tuck position with one minute of easy skating in an up right position ) expends 450 calories in thirty minutes. Mean while, Running and cycling expend 350 and 360 calories In-line skating offers tremendous potential to
enhance your fitness level. It yields the same cardiovascular benefits of high-impact
sports such as jogging, racquet ball, and basket ball without the undue stress to the
joints and muscular system. Anaerobically, in-line skating was found to be more
beneficial than both running and cycling because it is intrinsically easier and more
natural for building hip and thigh muscles that are not developed in the other two forms
of exercise. Unlike cycling, in-line skating develops hamstring muscles. And unlike
running, in-line skating is a low impact activity. Once again, low impact comes into play. It cannot be stressed enough that low impact activities are the best kinds, especially for the joints. Our joints must not be abused to their extreme. Your joints allow you run after a bus thats leaving or let you bend down to pick up something youve dropped or even to tie your shoe. They must be kept in good condition. The biggest reason is the prevention of arthritis. A separate study conducted at the Human
Performance Laboratory at St Cloud State University in Minnesota found that in-line
skating develops muscles in the entire upper leg, rear end, and hip, as well as the lower
back. Muscles in the upper arms and shoulders are also developed when arms are swung
vigorously while skating. |
