Assessment
Primary outcomes After ingestion of tested materials for 8 weeks, subjects perform resistance training with elbow flexors. Before and after resistance training,
1) maximal isometric contraction torque
2) range of motion
3) magnetic resonance imaging analysis for elbow flexors
4) muscle fatigue measured as a visual analog scale
Key secondary outcomes After ingestion of tested materials for 8 weeks, subjects perform resistance training with elbow flexors. Before and after resistance training, derivatives of reactive oxygen metabolites (d-ROMs) and biological antioxidant potential (BAP) in blood

Results 
The work output during CONs in the EPA group was greater than that in the placebo group at the fifth set. In addition, ROM in the EPA group was significantly greater than that in the placebo group immediately after exercise. The increase of CSA in the EPA group was significantly smaller than that in the placebo group immediately after exercise.

Baseline Characteristics 
Healthy men
Participant flow 
Subjects were randomly administered with EPA and DHA supplement or placebo by a double-blind method. The EPA group was administered EPA-rich fish oil, containing 600mg EPA and 260mg DHA per day for 8 weeks. The subjects performed 5 sets of 6 maximal CONs of elbow flexors. The work output and peak torque were assessed during exercise.
Adverse events 
Nothing
Outcome measures
