Adaptations of bite force and masseter muscle thickness to high-intensity physical training in professional athletes: a comparative cross-sectional study.
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. Cited by 2 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
backgroundThis study investigated how prolonged high-intensity physical training influences bite force and masseter muscle thickness, which are key indicators of adaptation in the masticatory system. Understanding the relationship between these variables may provide insights into occlusal function and performance optimization in professional athletes.
methodsThirty-four male wrestlers (Pro: 13; Npro: 21; age: 26.7 ± 9.3 years) participated in this comparative cross-sectional study. Bite force was assessed using pressure-sensitive films, and masseter muscle thickness was measured via ultrasonography. Group comparisons and asymmetry analyses were conducted using appropriate statistical methods.
resultsProfessional athletes exhibited significantly greater bite force (1071.7 ± 380.2 N) than non-professionals (856.9 ± 363.1 N, p = 0.032). Masseter muscle thickness was also higher in professionals (15.6 ± 1.5 mm right, 15.9 ± 1.4 mm left) than in non-professionals (13.6 ± 1.3 mm right, 13.8 ± 1.2 mm left, p < 0.01). Bite force asymmetry was more pronounced in professionals (70.1 ± 29.3 N vs. 43.1 ± 21.8 N, p = 0.017).
conclusionsThese findings suggest that high-intensity training is associated with distinct neuromuscular adaptations in the masticatory system. Such adaptations may affect oral stability, occlusal performance, and temporomandibular joint health. The results underscore the need for individualized strategies to optimize performance and prevent occlusal imbalances in athletes engaged in intense training.
