Effect of Blood fatigue factors following eccentric exercise on delayed muscle damage. Exercise Science, 13(2): 251-262, 2004. The purpose of this study was to examine the effect of blood fatigue factors following eccentric exercise on delayed muscle damage. The running tests were performed on a treadmill for 30 min and all subjects(n=10) of present study participated in two different kinds of experimental conditions.: one was level running(LR) and the others was downhill running(DR) at a decline angle -14 % with their favorable running speed.There were significant difference in the total VO2 between LR and DR conditions(p<.05). The mean blood CK activity of DR was higher than that of LR group at the 12 h, 24 h, and 48 h after finishing test, and there were significant difference between LR and DR conditions following the running exercise(p<.05). In the mean blood lactate concentration at the end of the 30 min running exercise, there were significant differences between LR and DR conditions(p<.05). In the mean blood ammonia concentration at the end of 30 min running exercise, there were significant differences between LR and DR conditions(p<.05). However, there were no significant differences in blood phosphorus concentration between LR and DR conditions at the end of 30 min running exercise(p>.05).In conclusion, an indirectly marker of muscle damage, serum CK activity was a significantly higher at the 12-24 h after downhill running in particular involves substantial eccentric exercise. Also, one of most effective blood fatigue factor on delayed muscle damage might be ammonia concentration and production during eccentric exercise. |
