Investigation response of HSP70 & liver enzymes and Cpk response to Eccentric Exercise Test

The purpose of the present study was to investigate the probable changes of HSP70، liver enzymes & Cpk in professional athletes after a training season and participating in skating open world championship. 10 elite female skaters were chosen. Eccentric exercise test were performed in three sections (24 hours before the beginning of the training، after six months of training (before participating in Skating World Championship) and 24 hours after the end of world championship). The training program consisted of 26 weeks of training، performed 5 times a week encompassing specialized skate trainings. Blood samples were taken before and after each eccentric exercise test. there was no significant change، in HSP70 concentration in response to eccentric exercise test، in pre exercise period (p>0. 898). But، it illustrated a significant increase in after eccentric exercise test، in post exercise period (p<0. 031). Moreover، in measuring down، it showed a significant increased in the amount of liver enzymes and Cpk after eccentric exercise test in second and third step compared to first step (p<0. 05). the results of the study illustrated that improving an athlete''s physical fitness level during training season and matches leads to a significant increase in the protective level of the body (via the production of HSP70)، depending also on the ability of the body of the individual in producing that protein. It can also be stated probably individual body fitness level، is an important factor in determining ALT، AST، ALP levels after performing eccentric exercise.
