Restoring Electrolytes for Athletic Performance

What vitamins have been found to offer benefits for restoring electrolytes and athletic performance?

There are a variety of nutrients shown in studies to provide benefits for restoring energy and improving athletic performance. Of course, taking a good multivitamin - one formulated with optimal amounts and forms of vitamins, minerals, antioxidants, herbs and amino acids - can help to ensure your overall health, from head to toe.

Multivitamins can provide benefits for countless health concerns, including immune, cardiovascular, vision, muscle, bone, and nerve health. And in regards to energy and endurance, these supplements have been shown to provide effective support. But for individual nutrients, the following vitamins have been shown to provide valuable sources of energy and endurance benefits:

o Vitamin C (ascorbic acid) - considered essential for general health and well-being, this multi-functional antioxidant may hold properties for energy and endurance. Deficiencies of this nutrient may be linked to feelings of malaise and generalized fatigue. Several published studies show that after several days of taking vitamin C (400-3,000 mg) daily before and after intense exercise, pain was reduced and muscle strength recovery was rapidly increased. It is thought that as antioxidants may neutralize free radicals before they can cause bodily damage, supplementation of these nutrients may aid in exercise recovery.

o Vitamin E (tocopherol, tocotrienol) - this thoroughly researched antioxidant has been found to slow cellular aging. Additionally, various published studies suggest that daily vitamin E supplementation (800-1,200 IU) may reduce free radical activity and muscle damage caused by strenuous exercise.

o Vitamin B1 (thiamine) - considered vital for every cell, this water-soluble (dissolves in water) B vitamin is essential for producing adenosine triphosphate (ATP), the body's fuel source. It processes carbohydrates, proteins, and fats, and is crucial for generating metabolic energy. In addition, thiamine is needed for the functioning of the muscles, heart and nervous system. It also promotes growth and good muscle tone.

o Vitamin B2 (riboflavin) - this multi-functional nutrient displays antioxidant properties, and helps convert carbohydrates into the fuel ATP. In addition, riboflavin plays a vital role in metabolizing carbohydrates, fats, amino acids and protein, and also activates folic acid and vitamin B6.

o Vitamin B3 (niacin) - besides playing a vital part in the production of ATP, this essential nutrient helps in more than 200 bodily processes. These include the release of energy from fats, the processing of alcohol, and the formation of hormones and blood cells. Vitamin B3 is crucial to energy metabolism and nervous system health, as well as for regulating cholesterol.

o Vitamin B5 (pantothenic acid) - a necessary factor in cellular energy production, this nutrient also contributes to the production of ATP, the body's energy source. Pantothenic acid is required for the production of lipids (fats), steroids and neurotransmitters. It is also essential for growth, reproduction, and normal physiological functions, such as the activation of the adrenal glands, which help to combat stress.

o Vitamin B12 (cobalamin) - shown be vital for preventing anemia, this nutrient is crucial for energy production, metabolizing carbohydrates, fat and proteins, and for promoting healthy growth and nervous system function. Plus, it may increase energy and promote growth in children.

o Biotin (vitamin H) - this essential B vitamin helps utilize protein, folic acid, and vitamins B5 and B12, while also metabolizing fat and carbohydrates. And, it has been shown to play a part in the production of ATP, the body's fuel for energy.

Lifexpand's Lyte'N Go Chewable Electrolyte Tablets have been formulated to offer an effective electrolyte supplement for restoring depleted minerals and other nutrients. These tablets are convenient, refreshing, sugar-free and low in carbohydrates. Think of Lyte'N Go as a "pick-me-up" for a depleted mineral and electrolyte; replace or even enhance your levels, and without the sugar or coloring.

Alcoholic Hepatitis

Ethanol has both direct and indirect toxic results about the liver as well as effects on numerous other organ systems from the body. Its direct effects may result from growing the fluidity of biologic membranes and thereby disrupting cellular functions. Its indirect effects about the liver are in component a consequence of its metabolism.

Ethanol is sequentially oxidized to acetaldehyde and then to acetate, with the generation of NADH and adenosine triphosphate (ATP). As a outcome of the high ratio of decreased to oxidized NAD that is generated, the pathways of fatty acid oxidation and gluconeogenesis are inhibited, whereas fatty acid synthesis is promoted.

Ethanol can also quantitatively and qualitatively alter the pattern of gene expression in various tissues but particularly in the liver, resulting in impaired homeostasis and greater sensitivity to other toxins. These along with other biochemical mechanisms may contribute towards the typical observation of fat accumulation in the liver of alcoholics and the tendency of hypoglycemia to produce in alcoholics whose liver glycogen has been depleted by fasting.

Ethanol metabolism also impacts the liver by generating acetaldehyde, which reacts with primary amino groups to inactivate enzymes, resulting in direct toxicity to the hepatocyte in which it's generated. Furthermore, proteins so modified might activate the immune program against antigens that had been previously tolerated as "self."

There may be substantial variation among people within the quantity of ethanol required to trigger acute liver injury. Regardless of whether nutritional, genetic, or other factors are responsible for these differences has not been determined. The specific pathologic features of alcoholic hepatitis include accumulation of Mallory's hyalin and infiltration of polymorphonuclear leukocytes.

Tennis - The Serve-How Important is It?

The serve is the most important foundation block of anyones tennis game, unless you are Dementieva! (smile. Just kidding.)

Statistically, about 60 to 65% of the whole game of tennis is serve and return, if you understand the importance of these figures, you will easily understand why professionals try to excel particularly in these areas.

When watching professional players it may give you the impression that all hit their serves flat and at a "zillion" miles per hour....consequently many of us, when in trouble with the serve, follow that rule with disastrous results.

Factors that lead to losing control of your serve, yourself and your game:

- Panic. Your hard first serve is not working, you start hitting harder and harder and less and less of your serves are going in.

What to do - Start your matches by gradually increasing the speed of your serve, by serving the first serve with more spin the usual (kick, twist, slice, your choice) in the first couple of games. As you gain condidence and get deeper into the match according to the score and situation start using your first serve with lesser spin and as a weapon.

- Fear. Your opponents get cocky and start jumping all over your second serves and pounding them for winners or attacking you and putting enormous pressure at the net. This kibd of outright intimidadtion leads you to barely push the serve over the net.

What to do - Once you get control of your first serve the occasional need to hit second serves will be a lot easier to manage. One thing you have to keep in mind is; second serves are all about courage. No matter how much pressure your opponent is trying to exert on you, stand tall, show him you are confident, be courageous hit your second serve just as if it was a first serve but with a lot more spin on it!

- Distress. Your heart starts pounding like the steam train to Manchuria, your thoughts start getting blurred and you start serving faults and double faults in a rapid fire sequence.

What to do - Take your time, bounce the ball several times on the ground, take a few deep breaths, compose yourself, focus on the target area where you want to place your serve and go for it!

Very important: No matter how hard Professional players hit their first or second serves they always apply one kind of spin or another, you should do the same.
