Introduction: It has been hypothesized that markers of delayed onset muscle soreness (DOMS) induced by eccentric training could be decreased by supplementing subjects with
vitamin E. Hence, this study was carried out to investigate the effect of vitamin E supplementation on DOMS indexes. Material & Methods: Twenty healthy male age 19 to 27 years
participated as subjects in this study. The subjects were assigned to either a supplemental (400 IU of vitamin E per day for one month; n=10 and 22.4 ± 2.5 years of age) or a
placebo group (n=10 and 22.7 ± 2.7 years of age) using a double-blind research design. peak power (PP) of Lower body, perceived pain, serum activity of the enzyme creatine
kinase (CK) and C reactive protein (CRP) were taken before, immediately and 48 hours after the eccentric exercise. Results: The results indicated that perceived pain and serum
levels of CK and CRP increased and PP of Lower body decreased significantly immediately after eccentric exercise in the both groups and these changes to be continued until 48 h
after the intervention. No significant differences were observed between supplemental and placebo group during the study.
Conclusion: In conclusion, vitamin E supplementation had no effect in ameliorating markers of DOMS induced by eccentric exercise. Further studies are needed to examine the effects of vitamin E supplementation on DOMS induced by eccentric exercise.

ir Abstract Introduction: It has been hypothesized that markers of delayed onset muscle soreness (DOMS) induced by eccentric training could be decreased by supplementing subjects with vitamin E.
peak power (PP) of Lower body, perceived pain, serum activity of the enzyme creatine kinase (CK) and C reactive protein (CRP) were taken before, immediately and 48 hours after the eccentric exercise.
Results: The results indicated that perceived pain and serum levels of CK and CRP increased and PP of Lower bodydecreased significantly immediately after eccentric exercise in15 the both groups and these changes to be continued until 48 h after the intervention.
Hence, this study has been carried out to examine the possible effects of Vitamin E supplementation on eccentric exercise-induced DOMS indexes.
Our results indicate that vitamin E supplementation does not affect eccentric exercise-induced muscle pain, PP of lower body and serum levels of CK and CRP.
(2010) investigated the effects of vitamin E (800 IU) supplementation on muscular and oxidative damage, as well as the inflammatory response induced by eccentric exercise on 21 participants.
5. Conclusion Our findings indicate that vitamin E supplementation (400 IU/day for one month) had no effect on perceived muscle soreness, membrane disruption (assessed by CK levels), inflammatory responses (assessed by CRP), or PP of lower body following a bout of eccentric exercise.
