- W2060100798 abstract "An increase in the activity of the serum or plasma creatine kinase (CK) is often used as a biochemical marker for muscle damage after eccentric exercise. CK is released into the circulation with eccentric exercise, and it generally peaks at about 3–6 days following the exercise (Jones et al., 1986; Ebbeling and Clarkson, 1989; Clarkson et al., 1992). Prior studies showed that a repeated bout of the same exercise did not result in as large an enzyme release as the first exercise (Nosaka and Clarkson, 1992,1994,1995). However, there is no study to examine the inter-subject variability in CK response following such a repeated bout of eccentric exercise. PURPOSE: This study examined the effects of a second bout of 70 eccentric contractions on the low, medium, high, and highest CK responders. METHODS: A group of college-males (22.8 SD 2.3 yrs, 172.8 SD 4.7 cm, and 66.7 SD 5.3 kg) performed a bout of 30 eccentric contractions one year before the first exercise. Subjects were then classified into low (less than 500 IU/L; n = 6), medium (500–2,000 IU/L; n = 6), high (2,000-10,000 IU/L; n = 5), and highest (more than 10,000 IU/L; n = 7) CK groups. The first exercise (ECC1) was 30 eccentric contractions of the elbow flexors using a dumbbell that was set at 80% of the pre-ECC1 maximal isometric voluntary contraction force (MVC) level. All subjects performed a second bout of 70 eccentric contractions (ECC2) 4 days after ECC1. Upper arm circumference (CIR), range of motion (ROM), and MVC were measured before, immediately after, and once a day for 9 days after ECC1. Plasma CK level and soreness were assessed before and once a day for 9 days after ECC1. RESULTS: there were significant changes (P < 0.05) in all parameters following ECC1 for all groups, with the exception of CK level for the low CK group (P > 0.05). There were no further changes (P > 0.05) in all parameters after ECC2 for the medium, high, and highest CK groups; however, there was a significant increase (P < 0.05) in CK between 3–5 days after ECC2 (7–9 days after ECC1) for the low CK group. CONCLUSION: When the inter-subject variability data were analyzed, a significant increase in CK was observed following the second exercise for the low CK responders. This information may be employed in future repeated bout effect studies to analyze increasing CK release, as such differences may not be apparent when analyzing CK for the group as a whole." @default.
