Endurance exercise effects on the contractile properties of single, skinned skeletal muscle fibres of young rats.
Article in Pflugers Archiv : European journal of physiology, 1991. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Single fibres were isolated from the extensor digitorum longus (EDL) and the soleus (SOL) muscles of the hindlimb from young male Wistar rats which had undergone a 10-week programme of endurance swimming from the age of 2 weeks. Fibres were mechanically skinned and activated with Ca(2+)- and Sr(2+)-buffered solutions. Muscle fibres were classified by means of well-defined criteria concerning various aspects of their contractile behaviour. Most fibres could be allocated into specific groups; however, a significant proportion (13% of the sampled population) did not fit these rigid classifications but displayed contractile activation characteristics common to more than one fibre type. In these cases models which used a combination of both fast- and slow-twitch contractile and regulatory properties were used to characterise the activation behaviour of fibres. It is proposed that the exercise, initiated at a young age, induced changes in the contractile characteristics of the single fibres by modifying protein isoforms of the contractile apparatus.
