Abstract

Introduction Ascorbic acid is a water-soluble vitamin solved in water that acts as a helper of some the enzymes in the reactions of energy metabolism. Thus, the study aims to investigate the use of supplemental ascorbic acid on the aerobic and anaerobic capacity of the children. Materials and Methods Participants of this quasi-experimental study were 18 children in Esfahan who were randomly selected and divided into 9 groups in pair (Aerobic exercise group and the control group). For 10 days before the start of the main trial, the participants in the control group received placebo and the experimental group received ascorbic acid. The average aerobic capacity was measured before and after 10 days of the use of ascorbic acid. The results were analyzed by SPSS version 18. Results Before and after 10 days of the use of ascorbic acid, the mean and standard deviation of the aerobic capacity of the experimental group were respectively (3.59± 0.38) and (4.23 ± 0.77) and of the control group, were (3.7 ± 0.40) and (3.7± 0.53) respectively. Therefore, there was a significant relationship between the use of ascorbic acid and placebo in terms of aerobic capacity (p � 0.05). Conclusion Results of the study indicated that the use of supplemental ascorbic acid would lead to increase the children's aerobic capacity. Therefore, the footballer children with no prior planning and no appropriate physical fitness who had to be involved in a heavy physical activity could use the results in order to decrease the consequences of a sudden involvement in a heavy physical activity.
