Application of Minimum Exercise Model to the Hypoxic Environment.
Review in Advances in neurobiology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
While moderate exercise has been demonstrated to enhance executive function, this beneficial effect may vary depending on the exercise environment. For instance, the decline in blood oxygen levels (hypoxemia) associated with ascent to high altitude has been shown not only to induce acute mountain sickness but also to potentially cause decreased cognitive performance. Therefore, exercise under hypoxic conditions may reduce oxygen delivery to various tissues, thereby attenuating the executive function-enhancing effects of exercise. Previous studies have examined the impact of exercise in hypoxic environments on cognitive function using cognitive task paradigms; however, a consensus has not been reached. One contributing factor to this lack of consensus is the insufficient investigation of how exercise in hypoxic environments affects neural activity in brain regions specific to cognitive function tasks. This limitation stems from the practical difficulties of utilizing positron emission tomography (PET) and magnetic resonance imaging (MRI) systems in hypoxic environments. We addressed these challenges by employing functional near-infrared spectroscopy (fNIRS), which requires only a compact experimental system, is portable, and can be readily installed in gym settings. Our findings revealed that exercise in hypoxic environments induces decreasing cognitive performance, specifically cognitive fatigue, by reducing task-specific neural activity. This chapter provides an overview of our research methodology and results.
