Serum macro-micro element responses to acute maximal physical exercise

Abstract

Purpose: In this study, it was aimed to examine the effect of acute maximal physical exercise on some macro - micro element levels in women. Method: Blood samples of subjects were drawn 2 times in total; shortly before and after the exercise. The flame atomic absorption spectrophotometric method used for analysis of zinc, calcium, magnesium and copper levels. Serum sodium and potassium concentrations were measured using ion selective electrodes. Results: It was found that there was significant increases for the zinc, calcium, magnesium, potassium and significant decrease for copper (p<0.01) while non-significant difference was found for the sodium parameter (p>0.01). Conclusion: As result our findings show that acute maximal physical exercise can lead to some changes on mineral metabolism in human. Such a diversity of results in the literature, indicate the importance of factors such as duration and intensity of exercise, fitness status of the participants, pre-exercise levels of mineral etc. © IDOSI Publications, 2013.
