【摘要】Purpose:Give the rats different sports drinkss and let them exercise for 30 minutes,then observe the changing of 5-HT level in their cerebral tissue and the ck level in their blood 30 minutes,60 minutes,and 120 minutes after the exercise;discuss the possible intervene principium of improve the fatigue of aerobic exercising rats by supplying different sports drinks.This experiment would supply some reference frames on public fitness group's sports drinks choosing when they're taking aerobic exercise.Methods:This experiment took the male SD(Sprague-Dawley) 54 rats as the objects.Use drinks1,drinks 2,and drinks 3 to fill their stomach,let the rats do the treadmill exercise that would take 64.0%±4.5%of their max oxygen uptake30 minutes.Then observe the influence of drinks1,drinks 2,drinks 3 on the changing of the 5-HT level in cerebral tissue and the CK level in their blood.Put 54 healthy.28±.10 Kg weight rats into 3 groups randomly:exercise+drinks 1group(group A);exercise+drinks 2 group(group B);exercise+drinks 3 group(group O.Then put the group A,B and C into the 30-minute post-exercise group(A1,B1,C1);60-minute post-exercise group(A2,B2,C2);120-minutepost-exercise group(A3,B3,C3).15 minutes before the exercise,fill the group A's stomachs with sports drinks 1;fill the group b's stomachs with sports drinks 2;fill the group c's stomachs with sports drinks 3.Let these 3 groups do the treadmill exercise that would take 64.0%±4.5%of their max oxygen uptake 30 minutes.After that,fill the group A's stomachs with sports drinks 1;fill the group B's stomachs with sports drinks 2;fill the group C's stomachs with sports drinks 3.Kill 6 rats in each group 30 minutes after the stomach filling;60 minutes after the stomach filling;120 minutes after the stomach filling.Check the 5-HT level in cerebral tissue;check the ck activity level and the HB level in their blood.Results:(1) Weight:drinks 1 group>drinks 2 group>drinks 3 group,the weight of group 1 and group 2 has no distinct difference,(P>.05);120mins group>30 mins group>60 mins group,the weight of 30 mins group,60 mins group and 120 mins group has no distinct difference between each two groups,(P>.05).(2) Hb:group A1,group A2,group A3's Ferro hemoglobin level has shown downtrend,there's no distinct difference between each two groups(P>.05);there's no distinct difference between each two groups(P>.05) in group Bl,group B2,group B3;there's no distinct difference between group C1 and group C2,but there's distinct difference between group Cland group C3(P<.01).group A1,B1 and C1 has shown downtrend and show no difference between each two groups,(P>.05);group A2,B2 and C2 has shown downtrend and shown no difference between each two groups,(P>.05);the compare between group A3 and B3,group A3 and C3 has shown distinct difference,(P<.01).(3) 5-HT:group A1,A2,A3 has shown downtrend,compare between group A1 and A3 has shown distinct difference,(P<.05);compare between group B1 and B2 has shown distinct difference,(P<.05);compare between group B1 and B3 has shown distinct difference,(P<.05);compare between group C1 and C3 has shown great distinct difference,(P<.01);compare between group A1 and C1 has shown distinct difference,(P<.05);compare between group A2 and B2 has shown distinct difference,(P<.05);compare between group A2 and C2 has shown great distinct difference,(P<.01);compare between group A3 and C3 has shown great distinct difference,(P<.01);(4) CK:the compare between each two groups in group A1,A2,A3 has shown no distinct difference,(P>.05);the compare between each two groups in group B1,B2,B3 has shown no distinct difference,(P>.05);compare between group C1 and C2 has shown no distinct difference,(P>.05);but compare between group C1 and C3,group C2 and C3 has shown distinct difference,(P<.05).compare between each two groups in group A1,B1,C1 has shown no distinct difference,(P>.05);compare between each two groups in group A2,B2,C2 has shown no distinct difference,(P>.05);compare between group A3 and B3,group B3 and C3 has shown no distinct difference,(P>.05).compared with group A3,group B3 has shown downtrend;group A3's level is distinctly under that of group C3,compare between those two groups has shown distinct difference,(P<.05).Conclusion:(1) This exercise is an aerobic exercise mode.(2) Supplying sports drinks 3 has reduced the fatigue of aerobic exercising rats,group sports+drinks3 has shown this conclusion most distinctly.(3) Results of the experiment shows ck level in blood changes little,that shows the exercise intensity is low.(4) Supplying drinks 2 and drinks 3 has active influence on reducing the Ferro hemoglobin level in the rats' blood.(5) When people take public fitness exercise,they could choose the cheap self-made sweet water.
