Table 3 Effect of supplementation on functional measures of muscle damage and fatigue following eccentric exercise

From: The effects PCSO-524®, a patented marine oil lipid and omega-3 PUFA blend derived from the New Zealand green lipped mussel (Perna canaliculus), on indirect markers of muscle damage and inflammation after muscle damaging exercise in untrained men: a randomized, placebo controlled trial

  1. *, p-value between groups at distinct time points (p < 0.05 denotes statistical significance between groups; p > 0.05 denotes no statistical significance between groups); ¥, significantly different (p < 0.05) to pre- supplementation (baseline) within group; #, significantly different (p < 0.05) from previous time point within group. Pressure pain threshold and thigh girth (swelling) are expressed as % change (Δ) from the pre- supplementation (baseline) value within group, since baseline values were significantly different (p < 0.05) between groups. DOMS, delayed onset muscle soreness; % ΔQtw,pot, % change in potentiated quadriceps twitch force from pre- to post-exercise (cycling time trial). Values expressed as mean ± SD.
