Abstract

Objectives: The aim of this study was to investigate the effects of vitamin C (vit C) supplementation on blood iron (Fe++), total iron binding capacity (TIBC), blood glucose and insulin levels in footballers and basketball players follow-ing three weeks of training and vit C supplementation.
Materials and methods: Blood samples from a total of 20 male sportsmen consisting of amateur footballers and basketball players were taken before and after experiment included an exercise on a treadmill with 1% tilt at a speed of 10 km/h for 10 minutes. Then, they were taken into training camp and they received 1 gr/day vit C daily for three weeks. At the end of the three weeks, blood samples were taken from the experiment groups and the levels of Fe++, TIBC, glucose and insulin were measured. Also, they were asked to fill a questionnaire about previous scores in com-petitions, and their habits on vitamin intake or smoking. Results of the questionnaire have been reflected as ratios.
Results: Data were analyzed and it was found that in both groups blood Fe++ and glucose levels of before and after exercise were elevated (p<0.01; p<0.001) while TIBC and insulin levels decreased (p<0.05). After supplementation of vit C, the Fe++ and TIBC levels in basketball players showed more increase compared with the footballers (p<0.001).
Conclusion: Our findings showed that vit C supplementation increased Fe++ levels and decreased TIBC.
