Abstract:
Objective To investigate the effects of cinnamic acid to enhance the exercise endurance in mice .Methods Through the exhaustive swimming to establish mice exhaustive exercise model ,the mice were divided into control group ,exercise control group and exercise cinnamic group(n=10) ,the mice exhaustive swimming time were comparted ,blood lactic acid(LAC) lev‐els were used to explore the endurance of cinnamic acid in mice;the super oxide dismutase (SOD) ,malondialdehyde (MDA) and peroxidase (CAT) content in liver homogenates were used to detect mice endurance enhancement and antioxidant capacity of cin‐namic acid ,and expression of Na+ /K+‐ATP enzyme ,Ca2+ /Mg2+‐ATP enzyme on mice quadriceps by Western blot to further study its effect on improving exercise capacity in mice .Results Cinnamic acid significantly prolonged the swimming time of mice;Exercise cinnamic group compared with control group:although the LAC content in plasma elevated ,the difference was not statistically sig‐nificant(P>0 .05) ,SOD and CAT in liver homogenate was significantly decreased(P< 0 .05) ,MDA increased significantly(P<0 .01) ,CAT was decreased but with no statistically significant(P>0 .05) ,the expression level of Na+ /K+‐ATP enzyme and Ca2+ /Mg2+‐ATP enzyme decreased significantly (P< 0 .01) .Exercise control group compared with control group:the LAC content in plasma increased significantly(P<0 .01) ,SOD and CAT in liver homogenate was significantly decreased(P<0 .01) ,MDA increased significantly(P< 0 .01) ,expression level of Na+ /K+‐ATP enzyme and Ca2+ /enzyme Mg2+‐ATP decreased significantly (P<0 .01);Exercise cinnamic group exercise control group:the LAC content in plasma was significantly reduced(P<0 .01) ,SOD and CAT in liver tissue significantly increased(P< 0 .01) ,MDA decreased significantly(P<0 .01) ,CAT decreased significantly(P<0 .01) ,the expression level of Na+ /K+‐ATP enzyme and Ca2+ /Mg2+‐ATP enzyme decreased significantly(P<0 .05) .Conclusion Cinnamic acid has good oxidation resistances and anti‐fatigue ability .
