Comparative changes in cardiovascular measures following speed, agility, and quickness training and small-sided games in youth football players: a randomized trial.
Article in BMC sports science, medicine & rehabilitation, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07633210 (Comparative Effects of Speed, Agility, and Quickness Training and Small-Sided Games on Cardiovascular Response in Youth Football Players), which is not on this 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.

Abstract
backgrounSpeed, Agility, and Quickness (SAQ) training and small-sided games (SSGs) are widely used in youth football but impose different physical and football-specific demands. Evidence directly comparing their cardiovascular responses following a structured training intervention remains limited.
objectiveTo compare cardiovascular response patterns following an 8-week SAQ or SSG training programme in male youth football players.
methodsThirty-six male youth football players were randomly allocated to an SAQ group (n = 18) or an SSG group (n = 18). Cardiovascular outcomes were assessed before and after the 8-week intervention and included resting heart rate (HR), post-shuttle-run HR, systolic blood pressure (SBP), and diastolic blood pressure (DBP). Pre-to-post changes were examined using a two-way mixed-design analysis of variance, with time as the within-subject factor and group as the between-subject factor.
resultsBoth groups demonstrated reductions in all four cardiovascular outcomes. Significant time × group interactions were observed for resting HR, post-shuttle-run HR, SBP, and DBP. SSG training produced greater numerical reductions in resting HR, SBP, and DBP, whereas SAQ training produced a slightly greater reduction in post-shuttle-run HR.
conclusionThe findings indicate different cardiovascular response patterns following SAQ and SSG training rather than universal superiority of either modality. SSGs may be useful when cardiovascular conditioning is integrated with football-specific technical and tactical demands, whereas SAQ training provides a more targeted stimulus for acceleration, agility, and neuromuscular performance.
