Comparison of plyometric repeated sprint and plyometric aerobic training on physical performance in youth soccer players.
Trial report in Scientific reports, 2026. 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
High-intensity interval training (HIIT) and repeated-sprint sets (RSS) are established conditioning methods in soccer, yet their integration with plyometric training among highly trained youth soccer players remains underexplored. This study investigated the effects of an 8-week program combining plyometric training with either RSS (PLYO-RSS) or HIIT (PLYO-HIIT) on physical fitness in young soccer players. Twenty-nine male players (14-15 years) were randomly assigned to PLYO-RSS (n = 14) or PLYO-HIIT (n = 15). Both interventions lasted 20 minutes per session and replaced part of regular soccer training. Physical fitness assessments included countermovement jump (CMJ), 15-s repeated vertical jumps (15''RJ), five-jump test (5JT), 10 m and 30 m sprint, maximal aerobic speed (MAS), VO2max, and repeated sprint performance (total sprint time, best sprint, fatigue index). Physiological markers (lactate, rating of perceived exertion, and HRmax) were also monitored. Significant improvements over time were observed in muscle power, sprint speed, aerobic capacity, and repeated-sprint ability (p ≤ 0.001; η²p = 0.339-0.489). However, no main effects or group × time interaction effects were observed, indicating no evidence of differential responses between the two training modes. In conclusion, integrating plyometric training with either RSS or HIIT effectively enhances physical fitness in highly trained youth soccer players, offering flexible options for training prescription.
