Introduction: Delayed onset muscle soreness (DOMS) refers
to the skeletal muscle pain that is experienced following
eccentric exercise. The aim of the present study was to
examine the effect of vitamin C on DOMS after an eccentric
exercise.
Material & Methods: Twenty healthy male age 21 to 24 years
participated as subjects in this study. The subjects were
assigned to either an experimental (3500 mg of vitamin C;
n=10) or a placebo group (Same dosage of juice powder;
n=10) using a double-blind research design. Knee range of
motion (ROM), perceived pain and serum activity of the
enzyme creatine kinase (CK), Lactate dehydrogenase (LDH)
and C reactive protein (CRP) were taken before,
immediately and 48 hours after the eccentric exercise.
Results: Lactate dehydrogenase, creatine kinase, CRP and
pain increased (P<0.05) and knee ROM decreased (P<0.05)
in the both groups immediately after the eccentric exercise.
The vitamin C supplementation decreased the pain and CRP
levels compare to the placebo group at 48 hours after the
eccentric exercise (P<0.05) but it has not effective to
improve LDH, CK and knee ROM.
Conclusion: In conclusion, further studies are needed to
examine the effects of vitamin C supplementation on DOMS
induced by eccentric exercise.

com Abstract Introduction: Delayed onset muscle soreness (DOMS) refers to the skeletal muscle pain that is experienced following eccentric exercise.
Knee range of motion (ROM), perceived pain and serum activity of the enzyme creatine kinase (CK), Lactate dehydrogenase (LDH) and C reactive protein (CRP) were taken before,immediately and 48 hours after the eccentric exercise.
(2006) also demonstrated that vitamin C supplementation has not effective to improve the eccentric exercise induced- DOMS (9).
The aim of the study was to test the effects of vitamin C supplementation on muscle soreness, muscle damage inferred from plasma enzyme activity changes and pain.
Physical and physiological characteristics (mean ± SD) of the subjects (View the image of this page) The knee ROM and the mean score of muscle soreness and pain before and after the eccentric exercise were presented in Table 2 and Table 3.
The results, also, showed that the mean score of muscle soreness and pain increase after the exercise in both group and the pain decrease in the supplementation group in compare to the placebo group (P Table 3.
These findings suggested that vitamin C supplementation may effective treatment for DOMS and exercise induced muscle soreness.
