Effects of training on lipid metabolism in swimming muscles of sea trout (Salmo trutta).

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
We examined the effect of exercise intensity and endurance training on plasma free fatty acid (FFA) kinetics and lipid metabolism in swimming muscles of reared sea trout. In both training groups [water current velocities 1 and 2 body lengths per second (bl s(-1))] the plasma level of FFAs decreased significantly (P < 0.001) compared to the control group. Similar significant (P < 0.01) post-exercise decrease was observed also in the lipase-esterase activity in the red muscle, but not in white. Moreover, in the group swimming with higher intensity a significantly higher (P < 0.05) lipase-esterase activity in the red muscle was found compared with the group on moderate exercise. As with cytochrome c oxidase activity, a significant elevation in the enzyme activity was also observed after training in the 1 bl s(-1) group in red and white muscle (P < 0.05 and P < 0.01, respectively). No changes were observed in beta hydroxyacyl CoA dehydrogenase activity. The lipid content was on average nine times higher in red compared to white muscle being 16.7, 21.1, and 24.9% in the red muscle of the control, 1 and 2 bl s(-1) groups, respectively, with a significant (P < 0.05) increase after training. We conclude that (1) unlike in mammals, plasma FFA kinetics and oxidation are not linearly related to exercise intensity in reared sea trout, (2) training enhances the capacity to uptake FFA from plasma, and (3) high intensity training shifts the proportion of energy derived from fat oxidation to carbohydrate-derived energy.
