Feature recess-time sports activities as a school-based intervention to improve fitness in rural Chinese youth.
Article in PloS one, 2026. 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
backgroundChina's national school health policies face persistent implementation gaps, particularly in rural high schools prioritizing Gaokao. National surveys (2010-2019) documented alarming fitness declines: 50-m sprint speeds decreased (+0.3s boys; + 0.4s girls), pull-ups/sit-ups fell 29%/20%, and standing jumps shortened 6-7 cm.
methodsA 16-week cluster quasi-experiment assigned intact rural high school classes (N = 98; age = 16.35 ± 0.48years) to: • Experimental (n = 50): Feature Recess-Time Sports Activities (FRTSA; 5x30-min/week). • Control (n = 48): Standard supervised running. Blinded assessors conducted the National Student Physical Health Standard tests.
resultsFRTSA elicited significant improvements versus control: • Speed: 50-m sprint (p < 0.001, η2 = 0.18, d = 0.75). • Explosive Power: Standing jump (p = 0.022, η2 = 0.05, d = 0.41). • Flexibility: Sit-and-reach (p < 0.001, η2 = 0.12, d = 0.60). • Strength: Male pull-ups (p = 0.030, d = 0.41); female sit-ups (p = 0.029, d = 0.45). No endurance benefits emerged (1000m/800m: all p > 0.05, d ≤ 0.18).
conclusionFRTSA is effective in enhancing speed, explosive power, flexibility, and strength, supporting policy integration of structured activity programs in rural schools.
