Daily requirements for protein are set by the amount of amino acids that is irreversibly lost in a given day. Different agencies have set requirement levels for daily protein intakes for the general population; however, the question of whether strength-trained athletes require more protein than the general population is one that is difficult to answer. At a cellular level, an increased requirement for protein in strength-trained athletes might arise due to the extra protein required to support muscle protein accretion through elevated protein synthesis. Alternatively, an increased requirement for protein may come about in this group of athletes due to increased catabolic loss of amino acids associated with strength-training activities. A review of studies that have examined the protein requirements of strength-trained athletes, using nitrogen balance methodology, has shown a modest increase in requirements in this group. At the same time, several studies have shown that strength training, consistent with the anabolic stimulus for protein synthesis it provides, actually increases the efficiency of use of protein, which reduces dietary protein requirements. Various studies have shown that strength-trained athletes habitually consume protein intakes higher than required. A positive energy balance is required for anabolism, so a requirement for "extra" protein over and above normal values also appears not to be a critical issue for competitive athletes because most would have to be in positive energy balance to compete effectively. At present there is no evidence to suggest that supplements are required for optimal muscle growth or strength gain. Strength-trained athletes should consume protein consistent with general population guidelines, or 12% to 15% of energy from protein.

Synes vi burde hatt dødstraff i Norge...   Fengsel for slike? Sammenlignet med forbrytelsen blir både steining og henging humant.

Neutralization of Western diet inhibits bone resorption independently of K intake and reduces cortisol secretion in humans.
Maurer M, Riesen W, Muser J, Hulter HN, Krapf R.
Medizinische Universitatsklinik und Zentrallabor, Kantonsspital Bruderholz, CH-4101 Bruderholz/Basel; Institut fur klinische Chemie und Hamatologie, Kantonsspital, CH-9007 St. Gallen, Switzerland; and Genentech, Incorporated, South San Francisco, California 94080-4990.
A Western-type diet is associated with osteoporosis and calcium nephrolithiasis. On the basis of observations that calcium retention and inhibition of bone resorption result from alkali administration, it is assumed that the acid load inherent in this diet is responsible for increased bone resorption and calcium loss from bone. However, it is not known whether the dietary acid load acts directly or indirectly (i.e., via endocrine changes) on bone metabolism. It is also unclear whether alkali administration affects bone resorption/calcium balance directly or whether alkali-induced calcium retention is dependent on the cation (i.e., potassium) supplied with administered base. The effects of neutralization of dietary acid load (equimolar amounts of NaHCO(3) and KHCO(3) substituted for NaCl and KCl) in nine healthy subjects (6 men, 3 women) under metabolic balance conditions on calcium balance, bone markers, and endocrine systems relevant to bone [glucocorticoid secretion, IGF-1, parathyroid hormone (PTH)/1,25(OH)(2) vitamin D and thyroid hormones] were studied. Neutralization for 7 days induced a significant cumulative calcium retention (10.7 +/- 0.4 mmol) and significantly reduced the urinary excretion of deoxypyridinoline, pyridinoline, and n-telopeptide. Mean daily plasma cortisol decreased from 264 +/- 45 to 232 +/- 43 nmol/l (P = 0.032), and urinary excretion of tetrahydrocortisol (THF) decreased from 2,410 +/- 210 to 2,098 +/- 190 &mgr;g/24 h (P = 0.027). No significant effect was found on free IGF-1, PTH/1,25(OH)(2) vitamin D, or thyroid hormones. An acidogenic Western diet results in mild metabolic acidosis in association with a state of cortisol excess, altered divalent ion metabolism, and increased bone resorptive indices. Acidosis-induced increases in cortisol secretion and plasma concentration may play a role in mild acidosis-induced alterations in bone metabolism and possibly in osteoporosis

Metabolic and endocrine effects of metabolic acidosis in humans.
Wiederkehr M, Krapf R.
Medizinische Universitatsklinik Bruderholz, Bruderholz/Basel, Switzerland.
Metabolic acidosis is an important acid-base disturbance in humans. It is characterised by a primary decrease in body bicarbonate stores and is known to induce multiple endocrine and metabolic alterations. Metabolic acidosis induces nitrogen wasting and, in humans, depresses protein metabolism. The acidosis-induced alterations in various endocrine systems include decreases in IGF-1 levels due to peripheral growth hormone insensitivity, a mild form of primary hypothyroidism and hyperglucocorticoidism. Metabolic acidosis induces a negative calcium balance (resorption from bone) with hypercalciuria and a propensity to develop kidney stones. Metabolic acidosis also results in hypophosphataemia due to renal phosphate wasting. Negative calcium balance and phosphate depletion combine to induce a metabolic bone disease that exhibits features of both osteoporosis and osteomalacia. In humans at least, 1,25-(OH)2 vitamin D levels increase, probably through phosphate depletion-induced stimulation of 1-alpha hydroxylase. The production rate of 1,25-(OH)2 vitamin D is thus stimulated, and parathyroid hormone decreases secondarily. There is experimental evidence to support the notion that even mild degrees of acidosis, such as that occurring by ingestion of a high animal protein diet, induces some of these metabolic and endocrine effects. The possible role of diet-induced acid loads in nephrolithiasis, age-related loss of lean body mass and osteoporosis is discussed.

Effect of chronic metabolic acidosis on the growth hormone/IGF-1 endocrine axis: new cause of growth hormone insensitivity in humans.
Brungger M, Hulter HN, Krapf R.
Klinik B fur Innere Medizin, Kantonsspital, St. Gallen, Switzerland.
The effects of metabolic acidosis on growth hormone and IGF-1 are poorly understood. We investigated the effects of chronic metabolic acidosis (induced by administration on NH4Cl, 4.2 mmol/kg body wt/day) on the growth hormone/IGF-1 endocrine axis in 6 normal male volunteers during metabolic balance conditions. NH4Cl administration resulted in hyperchloremic metabolic acidosis with plasma bicarbonate decreasing from 25 +/- 0.4 to 15.5 +/- 0.9 mmol/liter (P < 0.001). Metabolic acidosis significantly decreased serum IGF-1 concentration from 45 +/- 6 to 33 +/- 6 nmol/liter (P = 0.002), while serum IGF binding protein 3 concentration was not affected significantly. The growth hormone response to growth hormone releasing factor administration (1 microgram per kg body wt, intravenous bolus) was enhanced significantly during acidosis. The IGF-1 response to growth hormone administration (0.1 U kg body wt subcutaneously, every 12 hr for 48 hr) was blunted significantly during acidosis. Apparent endogenous serum half-life and metabolic clearance rates of growth hormone were not altered significantly by acidosis. Metabolic acidosis in humans results in a significant decrease in serum IGF-1 concentration without a demonstrable effect on IGF binding protein 3, and is related to a resistance to the hepatocellular action of growth hormone. The primary defect in the growth hormone/IGF-1 axis occurs via an impaired IGF-1 response to circulating growth hormone with consequent diminution of normal negative feedback inhibition of IGF-1 on growth hormone, as evidenced by the exaggerated growth hormone response to growth hormone releasing factor administration.

- That which you call your soul or spirit is your conciousness, and that which you call 'free will' is your mind's freedom to think or not, the only will you have, your only freedom, the choice that controls all the choices you make and determines your life and your character.
Rationality is the recognition of the fact that nothing can alter the truth and nothing can take precedence over that act of perceiving it.
Thanksgiving is a typically American holiday...The lavish meal is a symbol of the fact that abundant consumption is the result and reward of production.
Happiness is that state of consciousness which proceeds from the achievement of one's values.
Happiness is possible only to a rational man, the man who desires nothing but rational goals, seeks nothing but rational values and finds his joy in nothing buy rational actions.
The alleged short-cut to knowledge, which is faith, is only a short-circuit destroying the mind.
A creative man is motivated by the desire to achieve, not by the desire to beat others
Contradictions do not exist. Whenever you think you are facing a contradiction, check your premises. You will find that one of them is wrong.
When I disagree with a rational man, I let reality be our final arbiter; if I am right, he will learn; if I am wrong, I will; one of us will win, but both will profit.
The only power any government has is the power to crack down on criminals. Well, when there aren't enough criminals, one makes them. One declares so many things to be a crime that it becomes impossible for men to live without breaking laws.
The skyline of New York is a monument of a splendour that no pyramids or palaces will ever equal or approach
Why do they always teach us that it's easy and evil to do what we want and that we need discipline to restrain ourselves? It's the hardest thing in the world--to do what we want. And it takes the greatest kind of courage. I mean, what we really want
The desire not to be anything is the desire not to be.
Samtlige fra Ayn Rand.

Men huff, det er kjedelig, jeg kjenner meg selv så godt at jeg vet at jeg trenger et opplegg å følge.. som gjerne kan være i nærheten av fasting (men ikke helt..) Hvem gidder å lage et fullstendig kostholdsprogram for meg? som inneholder matvarer og klokkeslett...?
Jeg kan, hvis du lover meg nakne helkroppsbilder når dietten er over. |

Hele konseptet med en guddommelig person som i all evighet piner de egenproduserte vesenene som ikke tror på religionen hans (av den grunn at det ikke finnes et fnugg av rasjonelle beviser), er ufattelig for meg ihvertfall.
