Normative data and predictors of trunk muscle endurance performance in young tennis players.

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: Trunk muscle endurance is important for injury prevention and performance in tennis due to repetitive rotational and high-range motion loads. Normative data for youth tennis players is have not been established and the influence of body size and competitive rank on these measures remains unclear. The aim of this study was to establish age- and sex-specific reference values for trunk endurance and to examine the influence of body size and competitive success on endurance capacity. Methods: A total of 214 young tennis players (115 males, 99 females; age=14.1 ± 2.3 years) registered with the Croatian Tennis Association. Participants were stratified by national ranking into high-achieving (HA; ranked top 30) and low-achieving (LA) groups. Trunk flexor endurance was measured using the plank test, and trunk extensor endurance was measured using the Biering-Sørensen (s). Covariates included age, sex, height, and weight. Results: In female players, HA participants demonstrated significantly better trunk extensor endurance than LA participants (F = 5.35, Discussion: These results highlight the importance of structured trunk endurance training, particularly for female players, where core performance appears to be closely related to competitive success. Age and sex-specific normative values for these tests may assist coaches and researchers in evaluating, monitoring, and developing core strength and endurance in youth tennis populations, with potential implications for improving performance and injury prevention.
