| Abstract: | Rats on acute exhaustive swimming were used as experimental models. Sulfhydryl( SH), Glutathione(GSH), phosphlipase A 2(PLA 2) and free Calcium(Ca 2 ) of myocardial mitochondrion after exhaustive exercise in rats were investigated. The results showed that SH, GSH and Ca 2 content in myocardial mitochondrion after exhaustive exercise were significantly degraded than that of the resting group. According to the results, the relationship among the oxidant reduction reaction of exercise induced reactive oxygen species, the changes of myocardial mitochondria membrane structure and the fee calcium of matrix was discussed. It is suggested that increasing of PLA 2 activity might be a key parameter of fatigue after prolonged exhaustive exercise. By means of further observation the molecules mechanism of prolonged exercise induced fatigue appearance could be further deeply understood. |
