Physical and Physiological Characterization of Custom-Made Virtual Reality Exergames: A Pilot Study.
Article in Sports (Basel, Switzerland), 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
The continuous growth of the older adult population demands an urgent need to provide innovative ways to stimulate physical activity and promote functional health. This study presents FitFest, a custom-made virtual reality (VR) designed to deliver a complete physical activity (PA) session for older adults. A pilot study involving seven older adults (67.0 ± 3.8 years) was conducted, comprising 18 user testing sessions of two VR exergames: Wine Fest and Flower Fest. PA intensity and heart rate (HR) were measured. The rate of perceived exertion (RPE) and the participants' rating of the system's usability were also registered. Overall, sessions involved mostly sedentary behavior (56.5 ± 20.4%) and light PA (42.1 ± 19.3%), with an average of 436.7 steps and 92.1 bpm. Wine Fest elicited less sedentary behavior (53.6 ± 22.1% vs. 62.8 ± 16.2%), higher light PA intensity (44.7 ± 20.4% vs. 36.4 ± 17.0%), and a higher step count (503.0 ± 345.4 vs. 291.0 ± 143.1) than the Flower Fest, although not significantly. Tasks requiring cardiovascular effort and strength were rated as more physically demanding. Most participants found the system user-friendly and showed interest in continued use, though technical support was essential due to limited familiarity with VR. The findings suggest FitFest has potential to promote light PA in older adults, highlighting the importance of usability and support in tech-based interventions.
