This study aimed to evaluate and compare the thickness of the external oblique (EO), internal oblique (IO), transversus abdominis (TrAb), rectus abdominis (RA), and the inter-recti distance (IRD) between male and female climbers, using B-mode ultrasonography to identify potential sex-based morphological differences.
Significant sex-based differences were observed in the thickness of several abdominal wall muscles-specifically the right IO, right RA, left EO, left IO, and left RA. No significant differences were found in the remaining muscles. Overall, male climbers exhibited greater muscle thickness than females, except for the left EO, which was thicker in the female group. Regression analysis showed that sex was a relevant factor associated with RA thickness and contributed, to a lesser extent, to the variability observed in both IO and EO muscles.
This study highlights sex-related differences in abdominal muscle thickness among trained climbers. While male participants generally showed greater muscle thickness, the left EO was thicker in females. These morphological differences may reflect sex-specific anatomical adaptations, but further research is needed to determine their functional relevance. Current and future findings may contribute to the development of sex-specific training, rehabilitation, and injury prevention strategies in climbing.
本研究旨在使用B超评估和比较男女攀岩者腹外斜肌（EO）、腹内斜肌（IO）、腹横肌（TrAb）、腹直肌（RA）的厚度以及腹直肌间距（IRD），以确定基于性别的潜在形态差异。
在几块腹壁肌肉的厚度上观察到了显著的基于性别的差异，特别是右侧IO、右侧RA、左侧EO、左侧IO和左侧RA。其余肌肉未发现显著差异。总体而言，男性攀岩者的肌肉厚度大于女性，但左侧EO除外，女性组的左侧EO更厚。回归分析表明，性别是与RA厚度相关的一个因素，并且在较小程度上导致了IO和EO肌肉中观察到的变异性。
本研究突出了训练有素的攀岩者腹部肌肉厚度的性别差异。虽然男性参与者的肌肉厚度通常更大，但女性的左侧EO更厚。这些形态差异可能反映了特定性别的解剖学适应性，但需要进一步研究来确定它们的功能相关性。当前和未来的研究结果可能有助于制定攀岩中针对性别的训练、康复和预防损伤策略。
