Evaluation of aerobic and anaerobic capacity in pubertal karate athletes: performance analysis and development strategies.
Article in BMC sports science, medicine & rehabilitation, 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
backgroundThis study investigated the effects of gender's foot arch structure (normal arch vs. pes planus) on aerobic and anaerobic performance in pubertal karate athletes.
methodChildren with chronic cardiovascular and musculoskeletal diseases were excluded from the study. Participants included boys with normal foot arches (B-nfa, n = 7), boys with pes planus (B-pp, n = 11), girls with normal foot arches (G-nfa, n = 16), and girls with pes planus (G-pp, n = 11). Aerobic capacity was evaluated using the 6-Minute Walk Test, while anaerobic performance was assessed through the Vertical Jump Test and sprint tests (10 m and 30 m). The height of the foot arch was measured using the Navicular Drop test. Nonparametric data were analyzed using the Kruskal-Wallis test and Dunn's post-hoc test to identify significant differences. Parametric data were analyzed using one-way ANOVA and Tukey's post hoc test. Pearson's test was used for parametric correlation, while Spearman's test was used for nonparametric correlation. The significance threshold was set at p < 0.05.
resultsIndividuals in the G-nfa group exhibited higher anaerobic power than those in the G-pp group (p = 0.0452). There was a strong negative correlation between arch pes planus and Spear equations (r = 0.63, p = 0.0004). B-nfa participants performed faster than both B-pp (p = 0.0015) and G-pp (p = 0.0015). The G-nfa completed the 10 m sprint test faster than both B-pp and G-pp (p = 0.0052). B-nfa outperformed G-pp in the 30 m sprint (p = 0.036) and covered greater distances in the six-minute walk test compared to B-pp (p = 0.034) and G-pp (p = 0.002).
conclusionIn this study, we concluded that flat feet do not negatively affect the development of aerobic capacity in prepubertal children undergoing professional karate training. Still, they may significantly impact the growth of anaerobic power.
