Relation between Exercise Training-Induced Changes in Oxygen Uptake Kinetics and the Power-Duration Relation.

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
purposeThis study aimed to determine the relation between training-induced changes in the variable values of the power-duration relation (critical power [CP] and ) and those of pulmonary oxygen uptake ( ) kinetics (the fundamental phase time constant; , and the slow component amplitude; ).
methodsEleven healthy untrained males underwent 2 wk of severe-intensity exercise training. Before and after training, was assessed via an incremental exercise test on a cycle ergometer, CP and were assessed via constant power determination trials, and kinetics were assessed during exercise at a power output 10% above CP (posttraining at the same absolute and relative intensity as pretraining). A previously described and validated computer model of the human skeletal muscle bioenergetic system was used to provide further insight into training-induced changes.
resultsCP and were strongly inversely correlated before and after training, and their training-induced changes were also correlated. Computer simulations suggested that increased oxidative phosphorylation activity (k OX ) was the main factor determining the training-induced changes in CP and . Exercise training increased and reduced the amplitude of the , however, the training-induced changes in and were not correlated. Model simulations suggested that variations in k OX , the accessible phosphate (+creatine) pool (P acc ), and the peak inorganic phosphate (P i ) concentrations attained before task failure (Pi peak ) could explain the observed training-induced alterations in and .
conclusionsThe present study suggests that the bioenergetic mechanisms underpinning CP and are similar, whereas the relation between and appears somewhat more complex.
