Influence of ingestion of eicosapentaenoic acid-rich fish oil on muscle stiffness following eccentric contractions: a randomized, double-blind, placebo-controlled, parallel-group trial
- Conditions
- muscle stiffness
- Registration Number
- JPRN-UMIN000028165
- Lead Sponsor
- Hosei University
- Brief Summary
MVC torque and ROM were significantly higher in the EPA group than in the PL group after ECCs. Muscle soreness, upper arm circumference, and muscle echo intensity were significantly higher in the PL group than in the EPA group after ECCs. In addition, muscle stiffness at 150 deg was significantly higher in the PL group than in the EPA group immediately after ECCs.

- Primary Outcome Measures
Name Time Method After ingestion of tested materials for 8 weeks, subjects perform eccentric contraction (ECC) with elbow flexors. Before and after ECC, 1) muscle stiffness 2) range of motion
- Secondary Outcome Measures
Name Time Method After ingestion of tested materials for 8 weeks, subjects perform eccentric contraction (ECC) with elbow flexors. Before and after ECC, 1) maximal isometric contraction torque 2) muscle soreness measured as a visual analog scale
