1 · What the graph read from it

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.

2 · The registry

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 investigated the acute effects of dynamic stretching on mechanical properties of plantar flexor muscles and tested the hypothesis that it would result from an interaction between muscle-tendon stretching and muscle warm-up. To test the stretching effect, dynamic stretching (DS) was compared to static stretching (SS). To test the warm-up effect, DS was compared to submaximal isometric muscle activity (SIMA) with similar contraction intensity. A control condition served as reference. These four conditioning activities were time matched (2×20s) and tested on separate days on 13 volunteers. Electrical neurostimulation was applied to investigate muscle mechanical properties (peak doublet torque (PDT) and rate of torque development (RTD)), before assessing maximal voluntary isometric torque (MVIT). Passive torque and muscle fascicles length, were measured respectively with a dynamometer and ultrasonography during a maximal passive dorsiflexion. These parameters were recorded before and after each conditioning activities. MVIT, PDT, RTD and fascicles length remained unaffected, while passive torque was significantly reduced (-11.6 ± 14.8%) after DS. SS significantly decreased MVIT (-7.7 ± 3.8%) and enhanced fascicles length (45.3 ± 49.2%), whereas SIMA increased PDT (5.8 ± 5.2%) and RTD (7.4 ± 8.3%) without affecting passive torque or fascicles length. These results may suggest that, during dynamic stretching, muscle-tendon stretching effects would partly counteract muscle warm-up effects.
