A Comparative Research Of The Influence Of Different Antioxidants On Antioxidant System About The Short Distance Swimmer

Objective：To observe the influence of different antioxidants on antioxidant systemabout the short distance swimmer after the high-intensity intermittent training, andprovide reference for the selection of athletes of antioxidant supplements. Methods：The32male athletes were chosen randomly from the Beijing swimming team, whichrandomly divided into hydrogen water intervention group(E1), lycopene interventiongroup(E2), joint intervention group(E3) and blank control group(E4), each group ofeight people. Groups respectively add200ml hydrogen water,1grain of lycopene(100g/grain),200ml hydrogen water and1grain of lycopene,200ml water before threemeals per day. Choose intensive training stage for experimental intervention. Inintervention period, the general sports drinks as fluid infusion during the exercise.Intake of the other antioxidants was strictly controlled. Experiments conducted2weeks.Oxidative stress index(3-NT, MDA and8-OHdG, antioxidant defense systemindex(SOD, GSH-Px and T-AOC), Selective antioxidant index(O2-， H2O2and OH)were compared before and after the intervention when the athletes finished thehigh-intensity interval training. Oxidative stress index and antioxidant index in theserum with Elisa method, Selective oxidation index was determined by chemicalcolorimetric method. Results：Through the high-strength interval training, serum3-NT,MDA and8-OHdG concentration of each experimental group and motive control groupsignificantly rise (p<0.05); while serum SOD and GSH-Px activity significantlydecrease (p<0.05), and serum T-AOC concentration show some decrease rate in arelatively quiet state but no significant variance is found (p>0.05); the organism sendsoff large amounts of O2-, H2O2and OH. After the addition of hydrogen oxide, lycopeneand the joint intervention they offer, the indicator of oxidative stress injury evidentlydeclines(p<0.05),while anti-oxidant defensive ability greatly strengthens (p<0.05),which curbs the excessive generation of ROS (reactive oxygen species). conclusions:(1) Within the short time, the addition of hydrogen oxide and lycopene, with the effect oftheir joint intervention may significantly lower the oxidative stress injury on protein,lipid and DNA under the influence of high-strength movement, but there is no sign ofcooperative effect in the antioxidant.(2) Within the short time, the addition of hydrogenoxide and lycopene, with the effect of their joint intervention may significantly raiseAntioxidant enzyme activity, and strengthen the anti-oxidant defensive ability of theorganism.(3) High-strength interval training increase the concentration of O2-, H2O2and OH, and lower the inhibition ratio of the organism against O2-and OH. Hydrogenoxide, lycopene and their joint intervention could inhibit the excessive generation ofH2O2and enhance the inhibition ratio of the organism against O2-and OH. Hydrogenoxide appears to be more effective as shown in its inhibition ratio against OH, whichalso proves its out performance of selective anti-oxidant effectiveness.
