The Least Squares Method as a Tool for Assessment of the Stroke Parameters and Velocity in Monofin Swimming.
Article in Methods and protocols, 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
This study explores the application of the Least Squares Method to analyze and model the kinematic parameters in monofin swimming, focusing on stroke rate, stroke length, and the amplitudes of joint displacements at the hip, knee, and ankle. The primary aim is to evaluate whether this method provides an objective and diagnostic tool for assessing monofin swimming techniques. Three elite monofin swimmers were evaluated under a progressive fatigue test. Results indicated that the stroke rate increases velocity by 0.95, 0.23, and 0.96 units (for the estimated models respectively). Optimized stroke length (0.01-0.12 units) also significantly correlates with velocity improvements. Joint amplitude reductions, particularly at the hip and ankle, enhanced propulsion by minimizing drag. This study highlights the Least Squares Method as a diagnostic tool for optimizing swimming techniques, with potential applications in performance training.
