    The effect of zinc supplementation on Max Vo2 and lactate levels in sedentary people

    Results of previous studies have shown that exercise influences zinc metabolism. The importance of zinc intake by diet in athletes has been emphasized and it has been argued that zinc deficiency in the diet can have unfavorable effects on performance. The present study aims to investigate how zinc supplementation affects Max VO2 and lactate levels in sedentary people. The study included 10 male students who were not actively involved in sports. All subjects were supplemented with oral zinc sulfate (3mg/kg/day) for 4 weeks. Max VO2 and lactate levels of all subjects were determined before and after zinc supplementation. Max VO2 values of the subjects as measured after 4 weeks of zinc supplementation were numerically higher than the values measured before the supplementation, but the two values were not statistically different. Lactate levels, on the other hand, were found significantly lower after the supplementation, when compared to the levels before supplementation (p<0,05). Results of our study demonstrate that 4-week zinc supplementation leads to a significant decrease in lactate levels and delays exhaustion. Zinc supplementation can improve muscle strength and metabolism in physical activity. Consequently, physiological doses of zinc supplementation can be useful for performance. © 2018 by the authors.
