Validity and reliability of catapult vector S7 GNSS units in distance measurement.
Article in BMC sports science, medicine & rehabilitation, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
purposeThis study aimed to evaluate the validity and reliability of the Catapult Vector S7 GPS device in measuring total distance in a simulated team sport environment, with the specific goal of providing practical guidance for its application in sports science and practice.
methodsThirty university-level football players performed a Team Sport Simulation Cycle (TSSC), covering a total distance of 1200 m. Actual field measurements were used to test the validity of all values. A high-frequency (10 Hz) Catapult Vector S7 GPS unit was used to collect movement data, which was compared against reference tape measurements. Statistical analyses included SEM, CV%, SWC, MDC, MAPE%, MAE, RMSE, and Bland-Altman plots.
resultsThe device demonstrated excellent reliability with a CV% of 0.17 and SEM of 2.00. The MDC (5.54) exceeded the SWC (2.19), suggesting high sensitivity in detecting meaningful performance changes. Validity analyses showed minimal error (MAPE% = 0.77; RMSE = 11.55; MAE = 9.40). Bland-Altman analysis indicated low systematic bias and high agreement with reference distances.
conclusionsThe Catapult Vector S7 GPS unit provides highly reliable and valid measurements of total distance, supporting its application in monitoring athlete workload and performance in team sports. These findings underscore the importance of high-frequency GPS technology in sports science research and practice, significantly contributing to the field.
