The influence of the morphologic characteristics of connective tissue, which plays an essential role during sports activities, on sporting tasks needs further research given the controversial findings reported in the literature. This study aimed at examining the relationship between lower limb connective tissue morphology and drop jump reactivity and determining the influence of sex and athletic performance level. A total of 30 men and 14 women, runners, executed 6 drop jumps (3 × 20 cm and 30 cm height respectively) and their thickness and cross-sectional area were recorded for Achilles and patellar tendons and plantar fascia. No significant results were found in the relationship between the morphology of the connective tissue and reactivity strength index for both sexes. Significant sex differences were found, while women showed greater values ( < 0.005) for Achilles tendon and plantar fascia; men showed greater values for reactivity strength index and drop jump performance ( < 0.001). The present study shows a limited relationship between connective tissue morphology and drop jump reactivity. Additionally, women showed greater normalized values for Achilles tendon and plantar fascia, and men showed greater reactivity strength index and jumping performance values. No relationships between athletic performance level and connective tissue were found.
鉴于文献中报道的结果存在争议，有必要进一步研究在体育运动中起重要作用的结缔组织形态特征对运动任务的影响。本研究旨在探讨下肢结缔组织形态与跳深反应之间的关系，并确定性别和运动表现水平的影响。共有 30 名男性和 14 名女性跑步者分别执行了 6 次跳深（分别为 3×20cm 和 30cm 高度），记录了跟腱、髌腱和足底筋膜的厚度和横截面积。在两性的结缔组织形态和反应强度指数之间没有发现显著的关系。虽然研究发现了显著的性别差异，但女性的跟腱和足底筋膜的反应强度指数和跳深表现值较大（<0.005）；而男性的反应强度指数和跳深表现值较大（<0.001）。本研究表明，结缔组织形态与跳深反应之间存在有限的关系。此外，女性的跟腱和足底筋膜的归一化值较大，而男性的反应强度指数和跳深表现值较大。在运动表现水平和结缔组织之间没有发现关系。
