Effects of an 8-week unstable core training on trunk muscle strength and sprint performance among kayakers.
Trial report in PeerJ, 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
Background: Unstable core training (UCT), widely used in various sports to enhance trunk muscle strength and sprint performance, results in significantly greater gains in both outcomes compared to traditional core training (TCT). The study aimed to examine the impact of UCT performed on unstable surfaces (Both Side Up (BOSU) balls, Swiss balls and Wobble boards) Method: A randomized controlled trial was conducted, recruiting 60 eligible kayakers aged 14-19 years from the Ganzhou training base, China. Participants were randomly assigned to the UTC group and the TCT group. Both groups completed an 8-week core training program consisting of 1-hour sessions, 3 times/week. The difference is that the core training exercises of the UTC group were performed on unstable surfaces, while the TCT group was performed on stable surfaces. Trunk stability strength was assessed using the abdomen, back, and side bridge tests, while trunk dynamic strength was measured using the 1-minute sit-up, 1-minute back extension, and 1-minute trunk rotation tests. Sprint performance was evaluated using the 200 m single flatwater sprint time test. Statistical analyses were conducted Results: Both the UTC and TCT groups demonstrated significant improvements from pre- to post-intervention across all dependent variables. However, the analysis of between-group effects revealed statistically significant greater improvements in the UTC group compared with the TCT group at post-test. These differences included These differences included trunk stability strength in terms of abdomen ( Conclusion: The findings suggest that UTC may lead to greater improvements in trunk muscle strength and sprint performance compared with TCT over an 8-week intervention among young male Chinese kayakers. However, given methodological limitations (field-based strength tests and manual timing), results should be interpreted cautiously and require confirmation with more precise measurement methods in future research.
