effect of heat on minerals

367–370 in Metabolic Adaptation to Prolonged Physical Exercise, H. Howard and J.R. Poortmans, eds. Sullivan, and S.C. Skoryna 1982 Effect of exercise on concentration of elements in the serum. Redistribution of serum magnesium into red blood cells (Abbasciano et al., 1988; Deuster et al., 1987; Lukaski et al., 1983) and into adipocytes (Franz et al., 1985) with exercise has also been reported. Although there is a common perception that athletes as a group tend to have a high incidence of anemia compared to sedentary populations, hematological surveys of elite athletes have typically not supported this idea (Brotherhood et al., 1975; de Wijn et al., 1971; Stewart et al., 1972). Exposure to extremes in temperature by itself can result in a stimulation of the acute-phase response with subsequent changes in zinc metabolism (Sugawara et al., 1983; Uhari et al., 1983); sweat losses of zinc can range from 0.5 to 1 mg per liter (Aruoma et al., 1988; Van Rij et al., 1986). Frenkel 1989 The frequency of anemia and iron deficiency in the runner. 29:449–451. Carroll, S.L. The phenomenon of sports anemia has been associated with increased erythrocyte destruction, depressed iron absorption, increased sweat loss of iron, and gastrointestinal blood loss (Dressendorfer et al., 1991; Ehn et al., 1980; Frederickson et al., 1983; Paulev et al., 1983; Puhl et al., 1981; Stewart et al., 1984). Res. J. Appl. Keen 1987 Hypertension-induced alterations in copper and zinc metabolism in Dahl rats. (1983) reported that plasma copper concentrations decreased in male and female subjects following exposure to hot temperatures in a sauna bath.

Please enable it to take advantage of the complete set of features! The mechanisms underlying the development of exercise-induced hypozincemia are presumably multifactorial and may include impaired absorption of zinc, excessive sweat and urinary loss of the element, and an altered metabolism of zinc (Anderson et al., 1984; Deuster et al., 1989; Miyamura et al., 1987). Although the above observations suggest that selenium metabolism may be influenced by exercise, to date there is no compelling evidence that selenium supplementation is necessary for individuals engaged in endurance activities (Lane, 1989; Lang et al., 1987).

Although the average zinc intake during the field exercise was lower than zinc intakes in a sedentary control group of soldiers who were fed the same food, intakes by both groups were considered adequate. 1998 Jan;61(1):66-72. doi: 10.4315/0362-028x-61.1.66. Int. Sci. Runyan, and S.J. Space Environ. Lang, J.K., K. Gohil, L. Packer, and R.F. (1964) reported that the amount of copper lost via sweat can be considerable; men who were maintained at 37.8°C and 50 percent relative humidity lost as much as 1 mg per day in sweat.

Although the metabolic functions of chromium have not been clearly defined, chromium is known to be involved in the regulation of carbohydrate and lipid metabolism, presumably via a role in insulin action. 0000001316 00000 n 115 0 obj <> endobj J.

(1983) reported a case in which an exercise-induced reduction in plasma magnesium was associated with the induction of carpopedal spasms in a 24-year-old woman. Zinc absorption from typical foods ranges from 10 to 40 percent (King and Turnlund, 1989); thus the type of meal fed will have a significant effect on the zinc balance of individuals exposed to the above conditions. It is well recognized that iron-deficiency anemia can be associated with a diminished performance in maximal and submaximal physical exercise (Andersen and Barkve, 1970; Edgerton et al., 1981; Gardner et al., 1977; McDonald and Keen, 1988 and references cited therein).

Urinary zinc concentrations in the active soldiers increased from an average basal level of 400 µg per day to about 700 µg per day during the study. Note that an intermediate value for zinc absorption was used for these calculations. Hartley, D.E. 28:251–253. Dressendorfer and Sockolov (1980) have suggested that a high level of constant exercise can have long-lasting effects on zinc metabolism. Med. Couzy, F., P. Lafargue, and C.Y. Effects of high pressure and heat treatment on the mineral balance of goats' milk. $4�%�&'()*56789:CDEFGHIJSTUVWXYZcdefghijstuvwxyz�������������������������������������������������������������������������� ��� ? Given that prolonged exposure to a regimen of strenuous exercise and/or exposure to conditions resulting in high rates of sweat loss is associated with marked changes in zinc metabolism (see below), the potential negative effects of excess iron supplementation are clear. Hambidge, K.M. Coil. Keen, C.E. Am. 52:57–61. However, given the observation that typical selenium intakes are only on the order of 100 µg per day (Pennington et al., 1984), the loss reported by Consolazio seems excessive, and may reflect the technical difficulties involved in measuring this element.
