The validity and reproducibility of perceptually regulated exercise responses during combined arm + leg cycling.
Article in European journal of applied physiology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 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
purposeRating of perceived exertion (RPE) is a reliable method of assessing exercise intensity during isolated arm and leg cycling. The aim of this study was to assess the validity and reproducibility of perceptually regulated exercise responses during combined arm + leg cycling.
methodsTwelve males (age; 24.6 ± 5.3 years, height; 1.81 ± 0.7 m, mass; 83.1 ± 8.4 kg) initially undertook incremental exercise tests to volitional exhaustion for arm cycling (133 ± 14 W) and leg cycling (253 ± 32 W). On three subsequent occasions, participants undertook combined arm + leg cycling trials using two modified Monark ergometers involving three bouts of exercise at RPE 9, 13 and 17, in that order. Heart rate (HR), oxygen uptake ([Formula: see text]) and pulmonary ventilation ([Formula: see text]) were recorded continuously.
resultsNo significant differences were observed for HR (P = 0.086), [Formula: see text] (P = 0.525) and [Formula: see text] (P = 0.899) between trials, whilst significant differences were observed between each level of RPE (all P < 0.001). For % peak [Formula: see text], the ICC increased with successive trials for all RPE levels. For % maximal HR the ICC generally decreased with successive trials.
conclusionRPE can be used as a reliable frame of reference for the production of exercise intensity during combined arm + leg cycling without any formal familiarisation. Since combined arm + leg cycling elicits a greater energy expenditure than arm or leg work alone, this novel mode of non-weight bearing exercise might prove effective for aerobic conditioning and weight control.
