Assessment

Primary outcomes

After ingestion of tested materials for 4 weeks, subjects perform eccentric contraction ( ECC ) with elbow flexors. Before and after ECC,
1) Range of motion
2) Maximal isometric contraction torque
3) Muscle soreness measured as a visual analog scale

Results

ROM was significantly higher in the EPA and DHA group than in the PL group immediately after performing ECCs (p?<?0.05). A significant difference was observed in serum CK 3 days after ECCs (p?<?0.05).

Baseline Characteristics

healthy young men

Participant flow

Twenty-two untrained men were recruited in this double-blind, placebo-controlled, parallel design study and the subjects were randomly assigned to the EPA and DHA group (EPA and DHA, n?=?11) and placebo group (PL, n?=?11). They consumed either EPA 600 mg and DHA 260 mg per day or placebo supplement for 4 weeks prior to exercise. Subjects performed 60 ECCs at 100?% maximal voluntary contraction (MVC) using a dumbbell. Changes in MVC torque, range of motion (ROM), upper arm circumference, muscle soreness, echo intensity, muscle thickness, serum creatine kinase (CK), and interleukin-6 (IL-6) were assessed before exercise; immediately after exercise; and 1, 2, 3, and 5 days after exercise.

Adverse events

None

Outcome measures

MVC torque, range of motion (ROM), serum creatine kinase (CK), and interleukin-6 (IL-6)
