The relationship between preschool-based movement behaviors and physical fitness: a compositional data analysis.

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
backgroundPhysical fitness in preschoolers, encompassing muscular strength, speed-agility, balance, and cardiorespiratory fitness, serves as a key health indicator. While preschools are ideal settings for promoting physical fitness, the association between preschool-based movement behaviors and physical fitness remains unclear.
methodsThis cross-sectional study included 1144 Chinese preschoolers aged 3-6 years. Preschool-based movement behaviors including moderate-to-vigorous physical activity (MVPA), light physical activity (LPA), and sedentary behavior (SB), were measured using ActiGraph GT9X accelerometers. Physical fitness was assessed via the PREFIT battery, which includes handgrip strength, standing long jump, 4 × 10 m shuttle run, one-leg stance, and 20 m shuttle run. Compositional linear regression and isotemporal substitution modeling were employed to examine associations and time-reallocation effects, respectively.
resultsGreater amounts of MVPA during preschool hours were positively associated with better performance in muscular strength, speed-agility, and cardiorespiratory fitness. Reallocating time from SB or LPA to MVPA enhanced physical fitness, whereas substituting MVPA with SB or LPA reduced fitness levels, demonstrating an asymmetric effect.
conclusionsModerate-to-vigorous physical activity during preschool hours significantly enhances physical fitness. Prioritizing the implementation of physical activity programs to increase MVPA in preschool settings is crucial for improving physical fitness and addressing insufficient MVPA in this age group. IMPACT: First large-scale study (N = 1144) demonstrating preschool-based moderate-to-vigorous physical activity (MVPA) is essential for developing preschoolers' muscular strength, speed-agility, and cardiorespiratory fitness, complementing existing 24-h movement behavior research. Reveals critical asymmetry: Reducing MVPA time significantly harms fitness, with losses exceeding the benefits from equivalent MVPA increases. Provides objective evidence to guide policymakers in optimizing preschool schedules to prioritize MVPA for enhancing children's physical fitness.
