Subjects were male (n=12) and female (n=6) PE college students. Using isokinetic dynamometer, subjects were randomly assigned to performing exercise which consists of 30 knee extension and flexion at speeds of 60, 120, and 180 /s. Blood samples were collected before and after 0, 5, 15, 30, and 60 min of the exercise protocol. Hematocrit (Hct), blood glucose (Glu), lactate (La) were assessed and serum testosterone (T), progesterone (P4), and Estrodial (E2) were assayed by E.I.A. After analysis of variance (ANOVA), the 120 /s was used as exercise intensity for test-retest study. Subject were performed exercise passively or upon the protocol two times with 24 hours intermission. Blood samples were taken before and after 0, 5, 15, 30, and 60 min of the protocol and in pre and post intermission. All data was expressed as means ± SE. In some case, the treatment means was tested for homogeneity using an ANOVA, and different between specific means was tested for significant using Duncan's multiple range procedure. Testretest correlation coefficient was applied to establish reliability of sex steroid. Results showed that no elevation occurred in serum T, P4, E2 following knee extension and flexion at 60 /s and passive movement.. Exercise at 120 /s was increased sex steroids higher than 180 /s. Test -retest correlation was r = 0.67 - 0.89. It is suggest that isokinetic resistance exercise can induce sex steroid responses and movement speed is an important factor influencing those variations.45962 bytesapplication/pdf等速收縮; 性類固醇; 乳酸Isokinetic contraction; Sex Steroids; Lactatereport
