Whole Body Vibration — Consumer Basics

December 7, 2011 By Leave a Comment

f_21310573679_healthyfood.jpgWhole Body Vibration exercise is becoming a popular method of training, and for good reason, not only can vibration training work your muscles in a way that conventional training cannot, but also using a vibration machine has numerous proven therapeutic benefits too.

As more and more companies appear on the market each week, most giving conflicting information, it becomes difficult for consumers to know who to believe. In this article I hope to share some basic information backed by evidence as a guide for consumers when purchasing a Whole Body Vibration machine.

The first thing you need to understand before buying a vibration machine, is that there are basically just two types of vibration machines available, pivotal and vertical. A pivotal vibration plate vibrates from a centre axis in a see-saw like action. A vertical vibration plate vibrates straight up and down in a jack hammer like action. Both machines have proven benefits, and there is very little, if any, evidence to suggest one method is better than the other. As a consumer you will find marketers will tell you one method is better than the other, if you find this, ask for evidence and don’t take just their word for it. Personally I prefer pivotal vibration, with vertical vibration I feel there is too much unwanted vibration in the head, however I know others that prefer vertical vibration. I always suggest trying both methods first and see what you prefer. Pivotal platforms are sometimes referred to as oscillating platforms, as vertical platforms are sometimes referred to as lineal platforms.

Both platform types can have two variables that can be adjusted to produce different vibratory effects. The two variables of a vibration platform are,

1. Amplitude (vertical displacement)

2. Frequency (platform speed)

By adjusting either of these two variables we also change things such as, the number of times per second our muscles contract, the amount G force exerted on our body, the degree of difficulty in stabilising, the flow of blood through our body etc. Research and common sense tell us that different frequencies will have different effects on our body. Depending on what effects you are hoping to benefit from, will determine what frequency you should run your machine.

Next it is important to understand the recommended, researched, and safe variables when using each type of vibration platform.

For pivotal vibration the frequency range should be between 1 and 30Hz, the amplitude range should be no greater than 6.5mm (13mm maximum displacement).

For vertical vibration the frequency range should be between 25 and 50Hz, the amplitude range should be no greater than 3mm (6mm maximum displacement).

If you find a platform that has listed specifications outside of this range, chances are the specifications are incorrect, or the machine could likely produce harmful effects.

Today the biggest threat to consumers appears to be coming from the pivotal machine market. For this reason, and for the fact that I prefer a pivotal unit, I will now discuss pivotal machines only.

When purchasing a pivotal vibration machine, you should always ensure the platform has a full range of frequency, many machines being sold on the market today only reach frequencies below 20Hz. Such machines often make claims based on research that was performed on frequencies beyond the limits of their machine. Below is just a small sample of extracts from studies on a pivotal unit, indicating the frequency that was used.

The frequency of the vibrations used in this study was set at 26Hz

Adaptive responses of human skeletal muscle to vibration exposure.

In a parallel experiment (Bosco et al. in press) it has been noted that during vibration at 30 Hz the EMG signal of the biceps brachii muscle reached its greatest activity, thus this frequency was chosen in the present study

Influence of vibration on mechanical power and electromyogram activity in human arm flexor muscles.

The treatment group underwent whole body vibrations at a frequency of 26 Hz

New trends in science: The use of vibrations for enhancing performance

Objective: To test whether training on a high-frequency (28Hz) vibrating platform improves muscle power and bone characteristics in postmenopausal women.

Conclusion: Reflex muscular contractions induced by vibration training improve muscle power in postmenopausal women.

High-Frequency Vibration Training Increases Muscle Power in Postmenopausal Women

The whole vibration stimulus from the sole of the left and right feet was 3 minutes one time (shake frequency 25Hz) X 3 sets with a set interval was 10 minutes

Effect of Whole Body Vibration Stimulus and Voluntary Contraction on Motoneuron Pool

Vibration frequency was gradually increased during the first minute from 0 to 26 Hz and maintained at that frequency for the remaining five minutes.

Acute Effects of Whole-Body Vibration on Lower Body Flexibility and Strength

Vibration was with an amplitude a=1.05, a frequency of 26Hz, and hence a peak acceleration of 147 ms, or 15g.

Acute Physiological Effects of exhaustive WBV exercise in man

As you can see, a large number of studies suggest using a vibration platform at higher frequencies is beneficial for increasing muscle and strength. Therefore it is this one of the benefits you are looking for, it is important your machine can produce these higher frequencies. Not only that but, as you can see below research also suggests that the higher range of frequencies have far more benefits than the lower frequency range.

5-10Hz Optimum frequency range for,

Balance and Stability

11-16Hz Optimum frequency range for,

Relaxation of muscles

Injury rehabilitation

Blood circulation and lymphatic drainage

Mobilisation of joints

Healing scar tissue

17-22Hz Optimum frequency range for,

Muscle strength

Improved Co-ordination

Blood circulation and lymphatic drainage

Incontinence

23-30Hz Optimum frequency range for,

Muscle strength

Hormonal changes

Neurological stimulation

Increased mobility

Increased bone density (low amplitude)

Blood circulation and lymphatic drainage

Decreased lower back pain

Improved muscle tone

Ensuring a pivotal machine has a full range of frequency is just one of many factors you should check before buying a vibration machine. Other factors include ensuring the machine can give you a frequency reading, ensuring the machine gives an accurate reading of frequency.

Reduce Stomach Gas The Natural Way

December 6, 2011 By Leave a Comment

f_01310574137_men-track-meet.jpgAre there natural ways to reduce the gas you pass? Try preventive measures first. Learn how to move gas through your intestines more readily.

While there are several reasons you may find yourself to be gassy, there are many solutions for reducing belching, flatulence, abdominal bloating and pain. Excess gas commonly is associated with irritable bowel syndrome. Other serious gastrointestinal disorders usually produce other symptoms besides just being “gassy.”

Doctors usually recommend a plan to help move gas through the intestines more readily, combined with preventive measures, such as eliminating certain foods from your diet and avoiding chewing gum. Although many products on store shelves promise to help, their success is not guaranteed and often depends on the individual. There are also prescription medicines and some alternative therapies.

Keeping a diary of the foods and beverages you consume can help you systematically eliminate one food or group of foods at a time to determine which may be most responsible for your symptoms. One of the first questions at the top of the list would be ‘Could this be related to dairy products?’. If it is, the first step should be to eliminate these products from your diet for about seven days. If you feel better, then try to add dairy products back to your diet in smaller amounts to see if you can tolerate them.

There are some recommended home remedies and lifestyle changes. Chew more slowly and thoroughly because gas can be a sign of undigested food, the enzymes in saliva begin the first stage of breaking down food in the body’s absorption process. Avoid foods you know cause indigestion. Common food sources of gas include Brussels sprouts, bran, beans, milk products, cabbage, artificial sweeteners, carbonated beverages and alcohol. Take a short walk after you eat to prevent gas accumulation.

Maintaining a regular exercise schedule in the form of walking, jogging and calisthenics will help stimulate the passage of gas through the digestive tract. Perform chest-to-knee stretches. Lying on your back, bring your right knee to your chest. Hold for 10 seconds and, then repeat with the other knee.

If those remedies don’t provide relief, your doctor may recommend that you take an over-the-counter antacid, activated charcoal, or a lactase or bismuth product.

Antacids contain aluminum hydroxide, magnesium hydroxide (known as Milk of Magnesia), calcium carbonate, or other ingredients individually or in various combinations. Antacids help to control the symptoms of gastroesophageal reflux disease, a condition in which the stomach’s juices (acid and digestive enzymes) flow backward, or reflux, into the esophagus.

Tablets of activated charcoal may provide relief from gas in the colon. Studies have shown that when taken before and after a meal, lower-intestinal gas is reduced.

However, activated charcoal can cause black stools and constipation. While these are harmless side effects, black stools can be confusing to a physician, because color changes in stool can be a sign of a serious illness. Evidence concerning the benefit of activated charcoal is contradictory. Its effect in alleviating symptoms of intestinal gas has been supported by some studies yet refuted by others. As a result, physicians may recommend that patients consider trying activated charcoal to see whether its use results in some symptom relief. The usual dose is two to four tablets taken just before eating and one hour after meals.

Gas is often a symptom of lactose intolerance, which makes digesting dairy products difficult. It occurs when the body has too little of the enzyme lactase in the small intestine to break down lactose, the main sugar in milk and milk-based products. Although lactose intolerance can happen at any age, it tends to affect most people as they grow older. Lactase comes in liquid or tablet form. Adding a few drops to milk before drinking or chewing lactase tablets just before eating helps people who have difficulty breaking down lactose.

Bismut has salts to relieve inflammatory conditions of the stomach and intestines and can sometimes relieve gas. It also reduces the odor of unpleasant smelling gas caused by hydrogen sulfide, a sulfur-containing compound. Like activated charcoal, bismuth may result in black stools. Take before or after meals, on either an empty or full stomach.

In summary, stomach and intestinal gas is normal. Excess gas can be distressing, but rarely is it caused by a serious medical disorder. If your symptoms cannot be easily controlled or you have additional problems such as abdominal pain, change in bowel habits, or rectal bleeding, you need to contact your doctor’s office.

Gymnastics Provides A Great Fitness Option For Today’s Kids

December 6, 2011 By Leave a Comment

f_11310573622_healthyfood.jpgStudies show that today’s youngsters are a very inactive generation, and that inactivity and poor dietary habits have contributed to their lack of fitness. Statistics indicate that one in three kids is overweight or at risk of becoming overweight today, a percentage that has more than tripled in the last 30 years.

To help get kids off the couch and into better shape this summer, USA Gymnastics and Tyson Foods have joined forces to create a fitness initiative designed to encourage physical fitness through fun activities that emphasize four fundamentals of fitness: cardiovascular exercise, strength training, flexibility and nutrition.

To underscore this initiative’s importance, USA Gymnastics has expanded its annual National Gymnastics Day from focusing just on gymnastics to “A Celebration of Fitness.” Gym clubs and their members across the country use National Gymnastics Day in August as a way to give back to their communities by raising funds for the Children’s Miracle Network. The Tyson Fitness Challenge is the main vehicle for raising funds. Participants may gather pledges for specified activities that range from the traditional cartwheels and backflips to fitness-related skills or elements.

Each of the four fitness fundamentals in the Tyson Fitness Challenge helps kids get physically fit through participation in fun activities geared toward their level and age.

• Cardiovascular conditioning, which is important for the heart and lungs

• Strength training, which builds strong, healthy muscles

• Flexibility exercises, which help muscles move through a normal range of motion

• Nutrition, because a well-balanced diet is an important key to any fitness effort. Protein, like that found in Tyson chicken, beef and pork products, is an important part of any well-balanced diet because it delivers the necessary nutrition for strength and endurance.

In addition to focusing on four fundamentals of fitness, each participant will learn how to set fitness goals (e.g., being able to do five more sit-ups, three more push-ups, etc.) that may be achieved through the Tyson Fitness Challenge and continued as a part of his/her weekly routine.

“The basics of gymnastics are a solid foundation for building fitness at any level,” said Bela Karolyi, the legendary gymnastics coach who is a longtime proponent of the importance of fitness. “I have always stressed that flexibility, strength and cardiovascular exercise are important components to being fit or a good athlete, along with eating a well-balanced diet. The Tyson Fitness Challenge is designed to help young people learn how to exercise properly and eat right.”
