Phosphorus for energy metabolism in athletes -
Its other activities include: development of bones and teeth, multiplication of cells, activation of some enzymes and vitamins, and maintenance of body neutrality. It also participates in carbohydrate metabolism. Quite possibly athletes are ingesting three times the RDA.
Dr Tim Noakes, the eminent physiologist at Cape Town University and author of 'The Lore of Running' one of the greatest books ever written about road running and four other scientists decided to carry out an investigation into the causes of shin-soreness.
To do this, they brought together 12 sufferers from different sports not just runners. Their research was mainly confined to the type of training being done before the onset of the condition, what surfaces were mostly used, the strength of specific leg muscles and the gait of the foot on landing.
Almost as an afterthought, they did a mineral assessment of each athlete. To their astonishment they found that they were all below the average calcium level. Why was this? Their diet was examined and they were all found to be heavy consumers of cola-based drinks.
These drinks invariably contain phosphorus and so do some food additives. I knew one 5,m runner of note who consumed a giant-sized container of a cola drink after every training session. He trained twice a day and, coincidentally, he was invariably injured every three months.
It may well be a suggestion that a public health warning, similar to that on a packet of cigarettes, be stamped on every tin and bottle: 'Excessive consumption of this drink may damage your bones'.
The simple fact is that the more phosphorus that is ingested, the more calcium intake must be increased proportionately. Other things that affect calcium absorption are the phytates in bran and unleavened bread including chappatis.
Adequate vitamin D is also required for calcium to work properly; the same applies to an adequate supply of magnesium found in nuts.
It must be remembered that on average we possess 1,,mg of calcium in our bodies, and 99 per cent of it is needed for our bones and teeth. That said, it is astonishing to learn that phosphate boosting to improve performance in distance runners is producing good results.
As stated, ATP and CP, two high-energy chemicals which provide the energy necessary for muscle contractions, also prevent unwanted increases in muscle acidity and may also increase the flow of oxygen from the red blood cells to the muscles.
Several studies are worth noting. In the first, four grams of sodium phosphate per day were given to runners at the University of South Florida, which lowered lactic-acid levels and increased the V02 max of all 10 athletes involved.
Yet another study at Brigham Young University involving 11 active people who ingested 'Slim-O-Stam' a phosphate supplement failed to bring any improvements. Research at Adelphi University confirmed these findings.
However, at Old Dominion University, the exact method used by the University of South Florida on experienced triathletes saw the lactate threshold lifted by 10 per cent, the V02max by 9 per cent, and an 8 per cent improvement in a well-used time trial.
The latest research score is: four in favour, three against. One drawback is that no women were involved in the experiments, nor was anyone over 30 years of age. Non — Athletic Benefits of Phosphorus:. The following conditions may benefit from phosphorus:.
Phosphorus is added to many multivitamins — multiminerals. The RDA for phosphorus for adults is mg. The PDI performance daily intake of phosphorus for athletes and physically active adults is — mg.
The potential interactions of phosphorus are as follows:. Log in Register. Don't have an account yet? Register now! Remember Me. Phosphorous: Phosphorus is an essential mineral in the body. Food Sources and Absorption of Phosphorus: Phosphorus is present in foods high in protein, such as fish, red meats, chicken, turkey, eggs, dairy products, pumpkin seeds, and Brazilian nuts.
Factors that increase the absorption of phosphorus: Vitamin D. Vitamin A. PTH parathyroid hormone. High protein diet. High consumption of phosphorus, such as having many soft drinks.
They may contain up to mg of phosphorus per container. Factors that decrease the absorption of phosphorus: Large doses of calcium. Phosphorus and calcium can compete for absorption, and high doses of calcium lower the absorption of phosphorus.
For better absorption, the ideal ratio of calcium to phosphorus is or 1. Calcium — containing antacids. Aluminum — containing antacids. I ron. Athletic Benefits of Phosphorus: It provides the phosphate in ATP to produce energy. Helps synthesize protein and muscle growth. May aid muscle contraction and repair muscle damage.
According to the literature the steady-state level of phosphocreatine Eneergy has a linear relationship to metabolusm workload during Phosphorus for energy metabolism in athletes exercise afhletes below the Best fat burning exercises for weight loss threshold, whereas this athleyes is impaired during exercise intensities above the lactate threshold. The purpose Type diabetes causes this study was to investigate the linearity between PCr kinetics and workload during two bouts of isotonic incremental calf exercise with transitions from moderate- to high-intensity as well as from high- to moderate-intensity work rates. Using a whole-body 1. Changes in PCr, inorganic phosphate Pi and pH were statistically evaluated in comparison to the baseline. The exercise protocol started with a 4. The workload was increased in 2-min intervals up to 9 W during the first bout and up to 7.
