Therefore the aim of the current study is to investigate the effects of 6 weeks supplementation with fish
oil on muscle damage, muscle soreness and markers of oxidative stress following a bout of eccentric exercise.
Monitoring oxidative stress is not straightforward and so to give a detailed overview of the effects of fish oil on
oxidative stress we have chosen to measure 3 markers of oxidative stress. The markers chosen provide information
on lipid peroxidation (thiobarbituric acid reactive substances—TBARS), protein oxidation (protein carbonyls)
and oxidative damage to lymphocytes (DNA damage).
