The role that the ankle's physiological characteristics play in maintaining balance during quiet stance has been well documented. However, the role of the ankle in maintaining balance during more challenging conditions is questionable. As such, the objectives of this study were to identify any significant relationships between the physiological characteristics of the ankle joint and the ability to maintain more challenging unilateral stance.
21 healthy, adult athletes (age = 24.67 ± 5.42 years; height = 175.34 ± 7.48 cms; weight = 79.09 ± 14.07 kg).
Passive resistance and joint position sense in the sagittal plane of the ankle, and active dorsiflexion range of motion of each subject was assessed, in addition to centre of pressure parameters during 20 s unilateral stance.
Pearson's product moment correlation coefficient found significant positive correlations between D(peaktorque) and sway area (r = .554); A(x) range (r = .449); and A(y) range (r = .471). Significant negative correlations were found between P(peaktorque) angle and sway area (r = -.538, p = .012), A(x) range (r = -.590, p = .005) and A(y) range (r = -.439, p=.046).
The results highlighted limited relationships between unilateral stance balance control and the ankle characteristics commonly associated with quiet stance balance control and has, thus, further questioned the role that the ankle plays during more challenging stance conditions. The majority of balance training protocols in the athletic community focuses on the distal joints, however, this needs re-addressing in order to maximise performance.
踝关节的生理特征在静立姿势中维持平衡的作用已得到充分证明。然而，踝关节在更具挑战性的条件下维持平衡的作用是值得怀疑的。因此，本研究的目的是确定踝关节的生理特征与维持更具挑战性的单足站立能力之间是否存在显著关系。
21 名健康的成年运动员（年龄=24.67±5.42 岁；身高=175.34±7.48 厘米；体重=79.09±14.07 公斤）。
评估每位受试者在矢状面的被动阻力和关节位置感，以及主动背屈活动范围，此外还评估了 20 秒单足站立时的中心压力参数。
皮尔逊积差相关系数发现，D（peaktorque）与摆动面积（r=.554）、A（x）范围（r=.449）和 A（y）范围（r=.471）之间存在显著正相关。P（peaktorque）角与摆动面积（r= -.538，p=.012）、A（x）范围（r= -.590，p=.005）和 A（y）范围（r= -.439，p=.046）之间存在显著负相关。
研究结果强调了单足站立平衡控制与踝关节特征之间的关系有限，这些特征通常与静立姿势平衡控制有关，因此进一步质疑了踝关节在更具挑战性的站立姿势条件下的作用。运动界的大多数平衡训练方案都集中在远端关节，但为了最大限度地提高表现，这需要重新考虑。
