Effects of high-intensity functional training on physical fitness in healthy individuals: a systematic review with meta-analysis.
Synthesis in BMC public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 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
The purpose of this study was to conduct a meta-analysis of the effects of high-intensity functional training on the physical fitness of healthy individuals. This system review followed the PRISMA guidelines and has been registered in PROSPERO with the registration number CRD42023475055. As of January 2024, we did a thorough search across five databases: PubMed, Scopus, Web of Science, EBSCOhost, and Cochrane Library. We evaluated the methodological quality of the included study by TEST EX tool and ROB 2 tool. GRADE framework determines the level of certainty of evidence. Meta-analysis of random effects model calculations. 19 high-quality studies were included in this review, involving 911 healthy individuals. Positive effects were observed in improving strength (ES = 1.380; p < 0.001), power (ES = 1.320; p < 0.001), speed (ES = 3.093; p < 0.001), endurance (ES = 1.802; p < 0.001), and agility (ES = 2.086; p < 0.001). However, flexibility performance had no significant effect (ES = 0.640; p = 0.092), which may be attributed to limited articles. Therefore, it is necessary to expand high-quality research to explore the impact of HIFT on the physical fitness in healthy individuals.
