Saturation Nation

by Mike Gavareski

Red meat, eggs, and high-fat dairy products are all part of a disastrous health recipe, right? Well, yes, but only if you’re worried about the Y2K bug as well. The year is 2010, and the fear of saturated fat and cholesterol should no longer keep us awake at night. What once were thought to add pounds to a mid-section, the aforementioned nutrients do nothing of the sort, so says an array of more recent evidence.

The triple threat – cancer, heart disease, and diabetes – are all linked to weight and waist size. Both a higher weight as well as a larger girth of their waist correlates with a greater risk of the so-called triple threat. But don’t decrease your saturated fat intake! Well, you can if you want, but it won’t do any good. Two recent studies have shown that red meat, eggs, and high-fat dairy products do not increase the risk of these three factors. One study (tracking breast cancer in more than 319,000 women) showed that there was no link between breast cancer and foods with high amounts of saturated fat and cholesterol. The second study (examining both men and women) showed that waist circumference was inversely related to a diet rich in red meat, high-fat dairy products, vegetables, and even butter. The same study also showed a positive correlation between waist circumference and diets consisting of processed meat, potatoes, and snack foods.

So what should you do? Don’t worry about saturated fat and cholesterol, as long as it’s coming from the right sources. Eat meat. Eat red meat. Eat chicken. Eat eggs. But make sure it’s organic and grass-fed red beef, or free-range poultry. The dairy products you eat should come from the same, healthy, well-fed cattle. As long as your sources of these saturated fats and cholesterol are pure sources, the pounds will stay off, and you’ll benefit from an influx of high-quality protein, minerals, and antioxidants.

Telomeres and Exercise

By Evan Bylsma

A new study has shown, through molecular science, proof that exercise keeps you young. Exercise helping you live longer hasn't exactly been a secret and the millions of people worldwide that pour sweat at gyms weekly testify to that help. But now, scientific evidence for the age fighting power of exercise has been found at a molecular level.

Investigators have been measuring the length of "telomeres", which are the DNA on either end of thread like chromosomes. As it was described in the article, these telomeres act in a similar way as the plastic tips on the end of your shoelaces. Just as those little plastic wraps prevent the shoe lace from unraveling, telomeres protect the chromosomes that carry genes during cell division.

Every time your cells divide during replication telomeres inevitably get shorter. When a telomere is too short, the cell can no longer replicate and then dies. Scientists believe that telomere length, and specifically health, is directly linked to aging. Having shorter telomeres puts an individual at a higher risk of heart disease, diabetes and cancer.

There was very interesting data however, when scientists studied telomere length between groups of exercising animals and humans versus sedentary populations. Specifically, a population of middle aged adults who ran 50 miles a week or more hand longer telomeres then a healthy population of similar age that didn't exercise.

Many scientists now believe that exercise, rather then a persons inherited gene background, could be the most important factor that keeps an individual healthy and young. Through the study it was observed that those individuals that exercised the most had a similar telomere length to people that were 10 years younger and didn't exercise. Other studies showed that as little as 2 hours of exercise a week showed a significant difference in telomere length between twins.

Excess Post Exercise Oxygen Consumption (EPOC) is the prolonged boost that the body’s metabolism experiences after exercise. This EPOC effect is most pronounced after intense resistance training. Just like the training that we do at the X GYM. High Intensity Strength and Interval Training force a trauma to the body that must be recovered from. The “burn” that we feel when we strength train is actually the accumulation of lactic acid. This lactic acid is the by product of anaerobic exercise. Meaning that it is done with such a great intensity that oxygen is not being used. When the workout is completed the body must remove this lactic acid from the muscles, and replenish its fuel stores, as well as re oxygenate the blood. All of this requires energy.

Your body then is continuing to “work out” as you are getting back into your car, and go back to work or home or whatever you do after your workout. During this EPOC phase your heart rate is elevated above resting levels, and your body is also in an elevated fat burning state. This fat is being utilized to fuel these processes. So essentially you are doing your “Cardio” when you are done with your weights.

Studies have shown that the duration and level of the EPOC effect is most directly related to exercise intensity, not necessarily duration. This is why we advocate doing interval training for cardio. When someone does conventional “steady state” cardio the get an EPOC effect that is roughly equivalent to the amount of time they spent doing that activity. In other words, a thirty minute jog will result in 30 minutes of EPOC. Whereas a 20 minute high intensity interval training workout, will yield an EPOC effect of more than 80 minutes. More calories may be burned during the steady state workout than during the interval workout, but the net calorie and fat burn from the interval training workout, and the EPOC that ensues will be much greater.

This is one of the primary reasons why the X Gym workout has to be so intense. The harder the person lets the trainer push them during their workout, the longer and greater the EPOC effect will be, and therefore the more cardio and fat burning benefit they will receive.

Will a Glass a Day Keep the Doctor Away?

If you are one of the many people that think alcohol consumption may be leading you down a healthy path, you’re right. Well, partly. You’re also partly wrong. Study upon study relays evidence of alcohol’s (namely wine, but occasionally other drinks) benefit to the heart and preventing certain cancers. But don’t be so quick to smile if you have a glass of wine in your hand – that same beverage could be aiding other cancers in your body. Attention is being called to studies showing that alcohol consumption, even in moderation, may heighten the risk of mouth, pharynx, larynx, esophagus, liver, colon/rectum, and breast cancer. Not to mention the risks of what could happen when one consumes an amount deemed to be more than moderate.

Whether or not you give up your drinking habits is up to you. Drinking in moderation is still much better than heavy drinking. However, the consumer must be aware that drinking in moderation is not without risk. At one point in time, a drink per day for a woman, and even two drinks per day for a man seemed to fine, and even beneficial. Susan Gapstur, vice president of epidemiology for the American Cancer Society recommends further limiting alcoholic consumption if you are at risk for any of the aforementioned cancers.

What may burst the drinker’s bubble even more is the fact that there isn’t much excuse for alcoholic drinking in the first place. With today’s information, there are positive and negative affects of drinking alcohol. However, those on the positive side are mostly due to reservatol, a powerful antioxidant found in grapes. Thus, grape juice consumption can be equally as beneficial as wine, but without the negative affects!

How to Kick the Smoking Habit!

A recent study done by the University of Exeter has provided evidence for the first time that exercise can help people that are trying to kick their smoking habit. The specific study involved 20 moderately to heavy smokers who were required to fast from smoking for 15 hours before the test. They were then given 15 minutes of moderate exercise on an exercise bike and then shown smoking related images while their very precise eye movements were tracked. The results of the study showed an 11% decrease in the amount of time a person spent looking at a smoking image after 15 minutes of exercise versus no exercise. Many other studies have shown that light to moderate exercise like a brisk walk have been able to help people curb cigarette cravings.

This study will hopefully open up a new door into the hundreds if not thousands of non-physical related ways that exercise can help people. For that matter, if light to moderate exercise is enough to help people curb one of the more addictive drugs in the world what can high intensity training help accomplish?

The growing amount of evidence that moderate exercise can significantly help smokers curb their habits is only the beginning. There is every reason to assume that many negative habits preventing people from turning a corner in their health couldn't similarly be helped with the inclusion of a regular regime of exercise.

PNF Stretching

PNF which stands for Proprioseptic Neuromuscular Facilitation is a form of stretching that involves a series of isometric (static) contractions with the muscle being stretched in order to improve its range of motion. These contractions will temporarily deactivate the muscle spindle allowing the muscle to be stretched further. The muscle spindle is what senses that the muscle is being overstretched, and signals it to contract in order to prevent injury. If these stretches and contractions are done properly, injury will not occur, and the range of motion of a given muscle group will be increased in a short period of time.

These stretches are usually accomplished with the help of a partner or a trainer. Many studies A study out of England published by the National Strength and Conditioning Association (NSCA) showed that using PNF stretching only three times per week was effective in increasing knee flexibility without compromising strength. This study supports the “Less is more” approach that we have here at the X Gym.

While flexibility is important, too much stretching can detract from results, especially if done right before strength training. That’s why we tell people at the X Gym to not stretch before their workouts. Stretching will take away the elasticity of the muscles and essentially make them weaker. This weakening of the muscles will lessen the effectiveness of the strength training workout, and also leave the person more prone to injury. I equate it to trying to use a rubber band that has had all the stretchiness taken out.

We therefore advise people to stretch after their workouts and on off days. This will help with recovery and prevent injury. Because of its intense nature, it is my feeling that PNF stretching should be done on separate days from your X Gym workout - preferably after a cardio workout, while the muscles are still warm and pliable.
