Acute effects of ultra-short aerobic and resistance, yoga-based mobility, and mindfulness meditation sessions on mental health: a randomized online study.

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
Introduction: Ultra-short activity bouts (<10 min) may represent scalable, low-barrier strategies for improving mental health, an increasingly important goal due to rising stress levels and the need for preventive approaches. Both physical activity (PA) and mindfulness-based practices are associated with psychological benefits but are assumed to operate through partly distinct mechanisms (e.g., physiological activation and affective stimulation in movement-based activities vs. attentional and emotional regulation in mindfulness practices). However, direct comparisons between these modalities in ultra-short formats remain scarce. This randomized online study therefore examined the acute effects of three brief activities-endurance and strength PA (ESPA), yoga-based mobility PA (YMPA), and mindfulness meditation (MM)-on perceived stress, positive and negative affect, and anxiety during the COVID-19 lockdown. Methods: German adults from the general population and university students ( Results: Across conditions, significant improvements from pre- to post-intervention were observed for perceived stress, negative affect and state anxiety. However, no significant Group × Time interactions were detected, indicating that modalities did not differ in their acute effects. The interaction for positive affect was marginally significant ( Discussion: Findings suggest that even a single ultra-short online activity session can produce immediate improvements in key mental health indicators. Comparable benefits may reflect shared regulatory mechanisms linking physical activity and mindfulness practices. Movement-based activities may additionally enhance positive affect. Conclusion: Ultra-brief online PA and mindfulness sessions appear similarly effective for short-term improvements in stress, anxiety, and negative affect. Such scalable micro-interventions may inform mental health promotion strategies in everyday settings.
