Impact of different swimming training on the levels of serum MDA,SOD and T-AOC

The purpose of this research is to investigate the impact of swimming with different duration and exercising frequency on mice's serum MDA,SOD and T-AOC. Two-month-old male SD mice were grouped into comparative quiet group,group of swimming for one hour(six times per day),group of swimming for two hours(six times per day) and group of swimming for one hour(three times per day). The swimming groups had swimming training without load for fourteen weeks and serum MDA,SOD and T-AOC were determined after exercising. The result shows as the follows:the changes of serum MDA after mice's swimming has a relationship with the exercising duration and frequency;the content of serum MDA of the mice with six-time swimming per week decreases while the content of mice's with three-time swimming per week has no change;serum SOD after swimming has no change but SOD/MDA is increasing;the consistency of serum T-AOC of all the swimming groups increases,which indicates that long-term proper swimming training can enhance serum T-AOC,thus decrease the content of MDA and improve SOD/MDA value,which contributes to the removal of free radicals.
