Analysis of the impact force and key technique of backward straight punch in different combat sports.
Article in Scientific reports, 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
Despite the prevalence of combat sports research, a comparative analysis of backward straight punches and sEMG activation across different martial arts disciplines remains unexplored. This study examines the impact force and sEMG characteristics of backward straight punches among athletes from Boxing, Tao Lu (Chinese Wushu), Karate, and a control group (Physical Education students) under randomized signal stimulation. Twenty-eight participants performed backward straight punches while impact force and muscle activation were recorded using a pendulum system and a 16-channel Noraxon wireless sEMG system. Results indicate that the Boxing group exhibited the highest impact force (3.96 ± 0.45 times body weight), followed by the Tao Lu, Karate, and Control groups. Muscle activation patterns varied significantly among groups, with a moderate positive correlation between impact force and the deltoid (r = 0.535) and brachioradialis (r = 0.365) muscle groups. The findings highlight differences in combat philosophies, with Boxing emphasizing effectiveness, Wushu and Karate focusing on controlled strikes, and Tao Lu prioritizing precision. These insights provide a biomechanical understanding of combat sports techniques, suggesting tailored training strategies for optimizing striking performance.
