Evaluation of plateau-potential-mediated 'warm up' in human motor units.

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
Spinal motor neurones can exhibit sustained depolarization in the absence of maintained synaptic or injected current. This phenomenon, referred to as a plateau potential, is due to the activation of monoamine-dependent persistent inward currents. Accordingly, activation of a plateau potential should result in a decrease in the excitatory synaptic drive required to activate a motor unit. This, in turn, has been suggested to cause a progressive decline in the muscle force at which motor units are recruited during repeated voluntary contractions. Such a progressive decrease in threshold force associated with preceding activation of a plateau potential is referred to as 'warm up'. Furthermore, activation of a plateau potential is thought to manifest itself as a decrease in the derecruitment force compared to recruitment force. Multiple muscles, however, can contribute to the detected force and their relative contributions may vary over time, which could confound measures of recruitment and derecruitment force. Therefore, the purpose of this study was to compare the recruitment and derecruitment forces of single motor units in the human extensor digitorum and tibialis anterior during repetitive triangular-force contractions in which the contributions of other muscles had been minimized. In both muscles, we found that the recruitment thresholds of single motor units were unchanged during repeated contractions, and that the derecruitment force was consistently greater than the recruitment force. These results suggest either that plateau potentials were not engaged (or were rapidly extinguished) under these experimental conditions or that changes in recruitment and derecruitment force are not suitable criteria for detecting them.
