Muscle Fatigue-How to Blast Through the Dreaded Muscle Failure that "Hits" Us All

If you've been working out for any amount of time, you're probably well acquainted with fatigue—that sensation of your muscles being "done," "cooked," "toast"... You know, the "please have mercy before I'm permanently trapped under this weight," or "you might just have to drag me off the track because I've collapsed" feeling.

We typically use the term fatigue to describe general sensations of tiredness and the accompanying decreasing muscular performance. What this really means is we "hit the wall" and can no longer perform reps on a particular lift; we can no longer run any farther or harder; we can no longer produce the "optimal" output of muscular contractions as we did at the beginning of the set or workout.

What Is Muscle Fatigue?
Fatigue is a very complex phenomenon in which multiple sites fail during muscular work. The underlying causes of fatigue fall into one of two categories: central (neuromuscular—the mind/central nervous system) and local (peripheral—the actual muscle site).

The central nervous system (CNS) acts much like an automobile engine regulator. Most cars are made with a regulator that causes them to "shut down" when the engine revs too high for too long. This mechanism protects the engine from "over-heating." In the same way, our brains attempt to protect our muscles from tearing by reducing the rate nerve impulses are sent to our working muscles. In most cases, you'll experience central fatigue before local fatigue. In other words, when you think you simply can't do any more work because you're so fatigued, essentially what's happening is your mind is telling your body (muscles) to shut down. But in fact, you're probably able to continue for another couple of reps.

"...when you think you simply can't do any more work because you're so fatigued, essentially what's happening is your mind is telling your body (muscles) to shut down."Local fatigue is related to local factors that limit the ability to perform muscular work. These include the energy systems (ATP-CP, glycolysis, and oxidation); the accumulation of metabolic byproducts (such as lactic acid); and the failure of the muscle fiber's contractile mechanisms. The energy systems act much the same way as fuel in a car or a battery in a flashlight. However, humans are different in that we have three energy systems within the muscle's cells that are called upon at different times depending on the intensity and duration of an activity.

The first energy system is called the ATP-CP system and is called upon during extremely short and intense bouts of exercise (e.g., weight training, sprinting, and jumping). It works by repeatedly breaking down ATP (the basic currency of energy in the body) and rebuilding ATP using CP (creatine phosphate). During repeated maximal contractions, fatigue coincides with CP depletion.

The other two energy systems are called into play during exercises that last longer than 30 seconds. Known as anaerobic (or glycolytic) and aerobic (or oxidative), these energy systems are very dependent on the availability of glycogen (the stored form of glucose—sugar). As with CP use, the rate of glycogen depletion is controlled by the intensity (i.e., how hard you train) of the exercise.

During sprinting, for instance, muscle glycogen may be used 35 to 40 times faster than during walking. Glycogen depletion and hypoglycemia (low blood sugar) limit performance in activities lasting longer than 30 minutes. Long-distance runners often speak of "bonking" or "hitting the wall." This refers to a perceived fatigue usually related to glycogen depletion. At this point, the body begins to use other forms of energy, such as fat and protein (which are not as efficient sources, thus making it harder to sustain energy levels).

During high-intensity anaerobic exercise, such as sprinting and weight training, our bodies produce metabolic byproducts such as lactic acid and CO2. As these accumulate in our bodies, our ability to maintain the duration and intensity of exercise diminishes. And, when they finally reach a point of saturation, our muscle capacity comes to a screeching halt. This is often referred to as the "burn," whereby the muscle feels like it's on fire—signaling you to stop.

Got all that? I realize it sounds like some fairly complex processes, which they are, so here are a few instances I'm sure you can relate to that will help clarify how these energy systems work in our bodies, and more importantly, how we can assist our bodies to increase their output and delay (or temporarily overcome) the onset of muscle fatigue.

How Can You Overcome Muscle Fatigue?
While we can't completely overcome muscle fatigue, we can certainly delay it. But, sometimes this delay can be the difference between sprinters winning or losing in competition or allow weight trainers to "push out" a few more reps (to produce new levels of strength and muscle gains). There are many strategies we can use to accomplish this goal, but here are a few I've found over the years to be particularly effective:

Diet
First, we must ensure your diet is optimized. Consuming an adequate amount and ratio of carbohydrates, fat, and protein is paramount. Typically, endurance athletes require more carbohydrates (anywhere between 40 and 60% carbs) than strength athletes but slightly less protein (from 30 to 35%); whereas strength trainers (weight lifters) or those who regularly participate in sporting activities should consume equal or greater amounts of protein to carbohydrates on a daily basis (about a 40:40 ratio of carbs to protein). In essence, carbs are to the body like fuel is to a car—they provide the necessary fuel to maintain or sustain energy levels during workouts.



Hydration
A common mistake made by many athletes is the failure to stay well hydrated. I am not talking about drinking when you're thirsty (as you may know, thirst is a sign your body is already slightly dehydrated). The importance of being properly hydrated cannot be overlooked. Dehydration can lead to significant performance decrements, not to mention the risk of sickness and, in severe cases, death. Even a three to four percent drop in body water levels (signaled by thirst and fatigue) can decrease your muscular contractions by 10 to 20%. To combat this, at least 10 to 12 glasses (eight ounces each) of water (this doesn't count sodas, coffee, or juices) should be consumed daily—always including during and after events when your body is perspiring.

Recovery
Adequate rest is very important for delaying premature fatigue. Inadequate rest during training (i.e., between sets) and between workouts can cause unnecessary fatigue. A great rule of thumb for resting time between sets is just long enough to catch your breath. Squats take a little longer to recover from (maybe two to three minutes) because you're training such a large muscle group. For smaller muscles, like biceps, you would need a much shorter rest—more like 45 to 60 seconds at most.
Another quick tip: recent research that studied the effects of enhancing recovery between sets showed that keeping intensity high after completed sets allowed weight trainers to perform more reps in later sets compared with those who passively recovered (sat) between sets. This means we need to keep moving during rest periods, so instead of sitting down to rest, walk around or go to another exercise for a different muscle group.

One of the most common (and fatal) errors I see with weight trainers, both beginner and advanced alike, is over-training. Trapped by our "more is better" mentality, many of us seem to think if we train longer, harder, and more often, we'll multiply our results. Nothing could be more detrimental to your efforts to put on muscle and gain strength than training muscle groups too frequently. In fact, over-training can significantly impede the body's ability to properly recover and rebuild itself. Only through enough rest (which includes proper sleep) and an adequate number of days in between training, will the body be able to recover and rebuild itself. The most common signs of over-training are lethargy, chronic fatigue, continued muscle soreness, insomnia, and a decrease in strength. If you sense any of these coming on, try taking off a day or two more in between training sessions and see how you feel.

"Trapped by our "more is better" mentality, many of us seem to think if we train longer, harder, and more often, we'll multiply our results."For adequate recovery times between workouts (of the same muscle group), consider this: the smaller the muscle group, the faster the recovery; the more intense (speed of workout), the longer the recovery; and the higher the volume (i.e., the number of reps) and lower the load (weight), the faster the recovery, and vice versa of course. In general, I normally suggest not training a muscle if it's still sore, and then once the tenderness subsides, I say give it another day on top of that.

Supplements
There are many supplements that can help today's athlete postpone muscular fatigue. Endurance athletes may benefit greatly from carbohydrate/electrolyte beverages such as Revenge, Gatorade, Ultra Fuel, and a great new supplement called G-Push. These contain precise ratios of carbohydrates and electrolytes (vital salts and minerals) that can replace those lost during prolonged exercise, as well as enhance the body's ability to sustain long-term energy.

Nutritional stimulants such as caffeine (or its herbal counterpart guarana) can help delay fatigue for two reasons. First, it stimulates a cascade of hormones that cause a release of free-fatty acids into the bloodstream, causing the body to burn fat while sparing carbohydrates to use as energy. Second, it affects the CNS, thus postponing central fatigue and decreasing the perceived difficulty of the exercise.

However, if you can't handle the jittery, nervous-type feelings you get from stimulants (such as caffeine), you might give supplements like tyrosine or Ginkgo biloba a try. These supplements are not stimulants, so they do not affect your central nervous system (which causes the nervousness). Rather, they help increase your mental alertness and delay central fatigue (in the brain), thus helping to crank up your workout intensity.

And, let's not forget creatine monohydrate, which has been scientifically shown to aid short-duration, high-intensity exercise, such as weight training. It increases the body's creatine phosphate stores needed to replenish ATP, thus delaying the onset of glycolysis. In other words, creatine helps quickly replenish energy stores within the muscle cells, allowing you to work out longer and harder, which may lead to increased strength and muscle gains.

Last Words
So there you have it... there's nothing fancy here... but enough to get you through that next workout with a little more flare and pizzazz! With the information at hand, you're now armed with practical, safe, scientifically sound methods to overcome muscle fatigue, so you can train harder (possibly even longer) and become stronger, both mentally and physically—making every workout that much better.

Home Espresso Machine

The coffee craze has swept the nation! Starbucks are popping up on every street corner, in grocery stores, book shops, shopping malls, and even libraries. This coffee fever has spread to fast food restaurants, cafes, and restaurants, who are striving to provide their customers with a wider variety that black coffee in a Styrofoam cup. Since everyone is walking around sipping espressos, cappuccinos, lattes, macchiatos, and every other coffee creation in existence, it is no surprise that the coffee business if a booming enterprise. If your yearly coffee budget has left you aghast, consider alternatives to buying those tasty espresso fixes. Many individuals find that the purchase of a home espresso machine can save them enough to pay for the machine many times over.

You do not have to have professional barista training in order to run a home espresso machine, as most are incredibly simple to use with perfect results each and every time. Instead of running out and buying a fantastically expensive espresso machine that you think will provide you with the best results, consider researching the most appropriate machine for your specific needs. A simple search on the World Wide Web will provide you with a great variety of machines that are geared towards individuals with a wide variety of needs.

For those individuals with smaller kitchens or limited countertop space, the stovetop varieties of espresso machines may be the best option. These machines are not electric and work on the principle similar to that of a double boiler. Although these espresso pots are not equipped with an element that froths milk, they can produce a great cup of espresso nonetheless.

Another option that is quickly becoming more and more popular is a machine that runs off specially designed pods. These pods contain the coffee ingredients and are inserted into the machine and the espresso is brewed. Pod espresso machines have come onto the market in the last couple of years, but are just reaching the height of their popularity. Instead of hassling with grinding coffee beans or spilling ground coffee, these pods are mess and maintenance free. Also, many of the top name brand coffee producers are making pods with their signature blends, allowing you to enjoy the rich taste without the mess.

If you are interested in directly recreating the fantastic espressos produced in your favorite coffee shop, turn to a professional espresso machine made for commercial purposes. Although these machines are often the priciest, largest, and loudest machines on the market, they are the ultimate luxury for those individuals wanting espressos at home. However, keep in mind that you do not have to spend hundreds—or even thousands—of dollars on a top of the line espresso machine to make excellent espressos in the comfort of your own home.

Exercise And Proper Diet: Indispensable Ingredients Of Fitness And Healthy Living

For the past several years, there is hullabaloo on the need to be slim and sexy. Grocery shelves are filled with several food supplements and other products that promise certain health and wellness benefits. Home TV shopping channels also offer everything from slimming tea to herbal soap to 'instant abs' exercise gadgets. Gyms across the country are fast gaining members who are willing to sweat it out just to burn excess calories from mindless munching and eating. There is also an increasing number of vegetarianism and raw food diet converts who vow to trade juicy hamburgers for fresh vegetables and fruits. People who are stressed out dream of luxurious spa treatments, Thai and Swedish massages, and detoxification diets. All of a sudden, there's the need to attain fitness and healthy living. This desire can be attributed to man's realization that the world he is living in is too polluted and toxic. Fitness and healthy living seems to be man's only hope in staying sane and sound in this otherwise hostile world.

If one wishes to achieve fitness and healthy living, he should go for 'holistic' approach. A person who wants to have super-fit body goes to the gym a lot and sticks to rigorous exercise routines. There's nothing seemingly wrong with this but he should also see to it he is eating the right kinds of food. It is not enough to be physically fit outside; one has to strive to be internally and externally healthy. Body builders have to follow specific diets appropriate for his physical needs. It is a must to consult personal trainers who can prescribe a proper workout routine and the corresponding diet needed for such routine. Furthermore, people with weight problems should not only focus on improving their diet. Overweight and obese people also need to regularly exercise. One sure way to improve one's health condition is through exercising and eating wisely. A person should consider these two key aspects as a two-in-one package.

Fitness and healthy living cannot be attained without the exercise of one's will. An overweight person cannot be fit and healthy just be watching TV all day and expecting to wake up slim the next morning. Fitness and healthy living requires a lot of effort and involves many decision-making opportunities. One must be really determined to improve his diet and religiously follow exercise routines to be able to resist temptations that may go along the way. Sometimes, it is too tempting to pig out a little more often and to just watch movies at home instead of exercising and eating good food. But if a person firmly decided to be slim and sexy, he should be willing to let go of life's needless pleasures.

Chocolate Covered Coffee Beans: A Fun Snack

Most people have some form of sweet tooth, and many also like the taste and smell of a fresh cup of coffee. Though the tastes of sweets and that of coffee are very different, they make a great match, since sugar helps to offset the slightly acidic bitterness of coffee. One of the best examples of this is the great taste of chocolate covered coffee beans. If you’re a coffee lover, a chocolate lover, or both, chocolate covered coffee beans make a great snack.

A Marriage of Flavors

Chocolate and coffee work well together, so much that some chocolates in Europe will have recommended servings that include serving with coffee, particularly dark chocolates. However, any kind of chocolate can make great chocolate covered coffee beans, even white chocolate. This sweet, crunchy snack gives you the mellow flavor of one of the favorite candies in the world with the tang and aroma of coffee. And even better, this is a snack with kick, since you’ll get a little caffeine rush from eating chocolate covered coffee beans.

Making Your Own

Some people are serious enough about their coffee to buy their own beans and grind them. If you’re serious about your coffee, then you can be just as serious about your chocolate covered coffee beans. By purchasing your own beans and chocolate, you’re guaranteed a quality product.

Making this great snack food is a snap; all you need is a pot to carefully melt the chocolate in, and some sort of device, whether a fork or a strainer, to remove the beans. Once the chocolate is melted, simply place the beans in the pot to coat, and then remove with the fork. Set on wax paper to harden overnight, and you’ll have a great snack that you made from scratch.

Buying Beans

The selection of coffee beans can be important in the making of chocolate covered coffee beans. You want to buy a medium or dark roast, since a light roast will simply be too acidic for chocolate covered coffee beans. This is one reason why chocolate covered espresso beans are a popular sell, since it’s a very dark roast.

You can bring out interesting flavor combinations with your chocolate covered coffee beans by purchasing flavored beans. Usually considered inferior by aficionados for creating a brew, they can add an extra kick to chocolate covered coffee beans. Give making this sweet, crunchy, snack a try and you’re sure to get hooked!

Naked Minerals, the makeup that is actually good for your skin

In a time where citizens are inundated with media articles and press reports describing the decline of air and water quality, educated consumers search to find products that provide safer, healthier advantages over conventional wisdom. Organic produce and all natural products tout the benefits of chemical-free lifestyles while still maintaining consistent quality. Although many of these products can be found in grocery stores and specialty food markets, few have found their way into the cosmetic aisle. Naked Minerals provides all the benefits of traditional cosmetics while improving skin quality with healthy, all natural ingredients.

Naked Minerals has only begun to find its place among quality, natural cosmetics and it will only continue to grow. Like other mineral makeup, Naked Minerals uses pulverized minerals and rocks to create a light powder that floats on the skin, creating a lightweight, natural look and feel. Since the powder in Naked Mineral cosmetics contains no additives, fillers, or binders, nothing is absorbed into the skin and pores are left open to let the skin breath. Because of this, Naked Minerals does not weigh down skin or look heavy. Instead, the minerals allow skin to regenerate and heal, providing a healthy atmosphere for cell development.

The natural ingredients in Naked Minerals provides an all-natural protective barrier against damaging sunlight while improving skin quality. The light layer of powder provides SPF 15 protection without the use of damaging chemicals. By floating on the skin, the minerals and mica protects the skin from ultraviolet sunlight while reflecting light in such a way that produces a look of radiance. This glow is a result of both light reflection and healthier skin. In addition to floating on the skin and allowing air circulation through the pores, Naked Minerals makeup contains skin-conditioning vitamin E and will not clog skin or flare acne. In fact, by allowing skin to breath while reducing the appearance of acne, Naked Minerals cosmetics creates an atmosphere in which blemishes can heal. Traditional pimple medicine and treatment clogs pores and increases oil production, causing even greater skin problems. Naked Minerals reduces the appearance of these blemishes while providing healthier skin conditions to promote healing.

Naked Minerals also provides relief from common skin conditions such as Rosacea, brown spots, dark circles, and sunburn. Not only will these natural cosmetics protect skin from continued sun abuse, but the minerals and powders even out skin tones, providing balanced color throughout the face. Naked Minerals skin products combine light reflecting powders that diffuse light around dark areas and create the appearance of smoother, younger skin while promoting healthier skin with each use. The versatility of each product provides a wide range of cosmetic use and skin protection in one small package. These products provide the radiant look while still maintaining healthy and natural beauty.

eep Your Blood Sugar Level Under Control

Controlling blood sugar (glucose) levels is one of the most important aspects of diabetes management. It will make you feel better in the short-term and it will help you to stay fit and healthy in the long term.

The National Committee on Prevention Detection Evaluation, the chromium and many interesting articles. People who do not have diabetes keep their blood glucose levels within a narrow range for most of the time. The beta cells in the pancreas are able to produce just the right amount of insulin at the right time and they are constantly fine-tuning the blood glucose level. People with diabetes do not have this fine control over their blood glucose levels.

This might be because the beta cells have been destroyed and there is no insulin production at all, as in Type 1 diabetes. Alternatively, it may be that the body does not respond to the insulin and/or not enough insulin is produced when it is needed, as in Type 2 diabetes. The approach to managing Type 1 and Type 2 diabetes is slightly different, but whichever type of diabetes you have, you will still need to step in and take over that fine-tuning of your blood glucose level.

Controlling blood glucose levels is a bit like trying to lasso an unruly animal. Blood glucose is dynamic; it changes constantly and it is influenced by a host of factors including your choice of food, how much you eat, the timing of your medication or insulin, your emotions, illnesses, your weight, and your body's resistance to insulin.

Some of these factors are relatively constant from day to day and are quite easily accounted for; some factors are more variable. No two days are ever exactly the same, or entirely predictable, and this makes it difficult. So, blood glucose is not easily lassoed.

In practical terms, you will need to learn about those things that raise your blood glucose level and those things that lower your blood glucose level. Then you will need to balance these factors on a day-to-day and possibly even hour-by-hour basis. This means coordinating medication, food and activity levels, whilst making appropriate allowances for stress, illness or changes in your daily activities.

You will be aiming to avoid the extreme highs and lows, trying to manipulate your blood glucose toward the normal range. You will be doing regular finger-prick blood glucose tests and using these results to help balance those things that make your blood glucose rise with those that make it fall. When you have evened out your blood glucose level you will still need to keep an eye on it and continue to make adjustments.

Controlling blood glucose is a continuous process and it will require your attention from now on, for the rest of your life. Don’t worry! It may sound daunting to you right now, but it will soon become second nature.

People who do not have diabetes have blood glucose levels between 4 and 8 mmol/l for most of the time. In general, people with diabetes should try to aim for test results between 4 and 10 mmol/l most of the time. Some people – pregnant women, for example – will need to aim for tighter control. Other people – young children, the elderly, or those at risk of severe hypoglycemia, for example – will need to aim for higher levels.

Your diabetes team will give you individual guidance on the blood glucose levels that you should be aiming for.

In the short term, controlling blood glucose levels is important in order to avoid diabetic emergencies – very high or very low blood glucose levels. Both of these conditions are unpleasant and can be dangerous, so they should be avoided if at all possible.

High blood glucose levels in Type 1 diabetes, if caused by a lack of insulin, can lead to a condition known as diabetic ketoacidosis or ‘DKA’ which can be fatal if it is not treated in time.

Using Rhubarb for Constipation

Vegetables like fruits and their juices have healing properties because of the fiber, antioxidants, vitamins, and minerals they have. For constipation, vegetables are an excellent source of minerals and fiber. In addition there are specific vegetables and their juices that stimulate the colon become more active.

The benefits of Vegetables

Juices are absorbed quickly into your bloodstream. As a result, your cells are provided quickly with nutrients that feed them and that wash away waste. Juices give you the opportunity to get quick relief from various body conditions such as constipation. Juices move into your colon quickly to cleanse it and to activate peristaltic action.

Eating and drinking vegetables and their juices provide you with minerals and nutrients that build your blood, tissue, bones, and cells. It is minerals that build every part of your body. It is minerals that keep your body’s pH at the required level. It is minerals that keep your body alkaline by neutralizing body acids.

It is minerals that build your colon wall tissues and cells so your colon can perform those activities that prevent constipation.

Keep in mind that some natural recipes for clearing constipation require drinking vegetable juices that are bitter or have a strong taste. As you will find, some of the vegetable juices taste good and some don’t. Remember you are dealing with a condition that needs clearing and that what you drink for this is not for pleasure.

As you drink some of these vegetable juices, you may find that you like certain ones and these can become your regular daily or weekly drink.

James A. Duke, PhD, in his book, The Green Pharmacy, gives the following constipation remedy using rhubarb,

“Rhubarb has strong laxative action so it is best to use it with other juices. Here’s how you can use this herb. Blend together three stalks of rhubarb, without leaves, 1 cup of fresh apple juice, and one quart of peeled lemons and one tablespoon of honey or maple syrup. This tart drink will help you with your constipation. Drink one glass three times a day.”

A smaller quantity of this rhubarb drink would be,

Blend three stalks of rhubarb, ¼ - ½ peeled lemon, a teaspoon of maple syrup, and ¾ cup of fresh organic apple juice. You may add more syrup if the taste if to harsh for you. Don’t use rhubarb leaves since they contain toxic chemicals.

Use rhubarb only raw since it is high in oxalic acid. Use it sparingly and do not cook it. Cooking converts the organic oxalic acid into inorganic oxalic acid. The body does not easily absorb inorganic oxalic and it forms crystal deposits in the kidney and throughout the body.

If you have arthritis or gout, do not use rhubarb.

In other articles, I will be discussing the use of other vegetables that provide good constipation relief.
