本研究旨在确定山地自行车手 (MTB) 和公路自行车手 (RC) 优先采用的感觉运动策略来控制平衡。 24 名 MTB 和 24 名 RC（越野奥运会、世界、洲际和全国冠军、环法自行车赛参赛者、公路世界杯比赛冠军）自愿回答有关自行车练习特征的调查问卷并进行感觉组织测试，旨在基于视觉和支撑表面扰动（C1（ES）至 C6（ES））评估 6 种不同感觉情况下的平衡控制。无论是在安静姿势睁开眼睛时（C1（ES），P = 0.011）还是仅体感信息被破坏时（C4（ES），p = 0.039），RC 的平衡表现均优于 MTB，这凸显了 RC 中更多地使用视觉来控制平衡。此外，在整个人群（MTB + RC）中，视觉比率（R-VIS = C4（ES）/C1（ES））与公路自行车骑行距离比例呈正相关（p = 0.28，p = 0.054）。在 MTB 中，本体感觉（体感比：R-SOM = C2(ES)(eycs closcd)/C1(ES)）的使用因越野骑行强度的增加而增加（p = 0.49，p = 0.018），而视觉（R-VIS）的使用则因公路骑行强度的增加而增加（p = 0.41，p = 0.048）。 MTB 和 RC 之间感觉组织的差异可以通过环境刺激和这些学科的技术特性所阐述的适应性过程来解释。 (C) 2008 Elsevier Ltd. 保留所有权利。
This study aimed to determine the sensorimotor strategies privileged by mountain bikers (MTB) and road cyclists (RC) for balance control. Twenty-four MTB and 24 RC (off-road Olympics, world, continental and national champions, Tour-de-France participants, on-road world cup race winner) volunteered to answer a questionnaire about the characteristics of cycling practice and perform a sensory organization test, aiming to evaluate balance control in 6 different sensory situations based upon visual and support surface perturbations (C1(ES) to C6(ES)). RC balance performances were better than those of MTB both during quiet stance eyes opened (C1(ES), P = 0.011) and when only somatosensory information is disrupted (C4(ES), p = 0.039), highlighting a higher use of vision to control balance in RC. Moreover, a positive correlation was shown in the whole population (MTB + RC) between the visual ratio (R-VIS = C4(ES)/C1(ES)) and the proportion of riding distance of on-road cycling (p = 0.28, p = 0.054). In MTB, the use of proprioception (somatosensory ratio: R-SOM = C2(ES)(eycs closcd)/C1(ES)) was increased by a higher intensity of off-road cycling (p = 0.49, p = 0.018) and that of vision (R-VIS) by a higher intensity of on-road cycling (p = 0.41, p = 0.048). The difference in sensory organization between MTB and RC could be explained by adaptive processes elaborated from environmental stimulations and technical specificities of these disciplines.
