加司，A，佐佐川，S，久保，T，和金久，H.核心稳定性练习对安静站立时姿势摆动的瞬时效应。J力量状态24(2)：382-388,2010-本研究旨在研究安静站立状态下核心稳定性练习对压力中心(COP)运动的瞬时影响。17名健康的年轻人(7名女性和10名男性)在两种情况下都被要求进行30秒的肘趾和手跟练习。实验前和练习后1min，受试者在测力台上重复安静站立30s，闭眼3次，试验间隔10s。两种运动干预后，最大内侧摆动幅度(34.7±-7.0 mm至30.2±-6.1 mm，p=0.0001)、内侧摆动标准差(6.4±-1.2 mm至5.8±-1.0 mm，p=0.0006)、平均前后摆动速度(14.1+/-2.5 mm/s至13.2+/-2.3 mm/s，p=0.004)显著降低。根据测力平台数据计算出的COP轨迹的平均内侧摇摆速度(22.8+/-2.8 mm/s至20.9+/-2.3 mm/s，p=0.004)，摇摆速度(29.3+/-3.9 mm/s至27.0+/-3.2 mm/s，p=0.002)，以及扫掠速度(73.2+/-23.4 mm(2)至62.0+/-19.7 mm(2)/s，p=0.005)。这一结果表明，核心稳定性练习的练习暂时减少了COP轨迹的面积，以及闭上眼睛安静站立时的内侧偏移量和总偏移量。将核心稳定性练习作为热身计划的一部分，对于在主要锻炼计划中暂时改善站立姿势控制可能有用。
Kaji, A, Sasagawa, S, Kubo, T, and Kanehisa, H. Transient effect of core stability exercises on postural sway during quiet standing. J Strength Cond Res 24(2): 382-388, 2010-This study aimed to examine the transient effect of core stability exercises on the motion of the center of pressure (COP) during quiet standing. Seventeen healthy young adults (7 women and 10 men) were required to perform elbow-toe and hand-heel exercises for 30 seconds in both cases. Before and 1 minute after the execution of the 2 exercises, the subjects repeated 30 seconds of quiet standing with eyes closed 3 times on a force platform with intervals of 10 seconds between trials. The intervention of the 2 exercises induced significant decreases in the maximal range of mediolateral sway (34.7 +/- 7.0 mm to 30.2 +/- 6.1 mm, p = 0.0001), standard deviation of mediolateral sway (6.4 +/- 1.2 mm to 5.8 +/- 1.0 mm, p = 0.0006), the mean speed of anteroposterior sway (14.1 +/- 2.5 mm per second to 13.2 +/- 2.3 mm per second, p = 0.004), mean speed of mediolateral sway (22.8 +/- 2.8 mm per second to 20.9 +/- 2.3 mm per second, p = 0.004), sway speed (29.3 +/- 3.9 mm per second to 27.0 +/- 3.2 mm per second, p = 0.002), and sweep speed (73.2 +/- 23.4 mm(2) per second to 62.0 +/- 19.7 mm(2) per second, p = 0.005) of the COP trajectory, calculated from the force platform data. This result indicates that the practice of core stability exercises transiently decreases the area of the COP trajectory and its mediolateral and total excursions during quiet standing with the eyes closed. Performing core stability exercises as part of warm-up programs may be useful for temporarily improving postural control during standing in main exercise programs.
