Static stretching (SS) and dynamic stretching (DS) are widely used as warm-ups before sports. However, whether stretching affects postural control remains unclear. We compared the effects of SS and DS on the plantar flexors and postural control during single-leg standing. Fifteen healthy young participants performed SS, DS, or no stretching (control). The stretch condition consisted of four sets lasting 30 s each. The control condition was a rest with standing for 210 s. Center of pressure (COP) displacement was measured using a force plate before and after each intervention to assess postural control during the single-leg standing task. The COP area, COP velocity, and anteroposterior (COP) and mediolateral (COP) range were calculated. DS significantly decreased in the COP range (21.5 ± 4.1 to 19.0 ± 2.5 mm; = 0.02), COP velocity (33.8 ± 7.6 to 29.8 ± 6.5 mm/s; < 0.01), and COP area (498.6 ± 148.3 to 393.3 ± 101.1 mm; < 0.01), whereas SS did not change in the COP parameters (COP area 457.2 ± 108.3 to 477.8 ± 106.1 mm, = .49; COP velocity 31.2 ± 4.2 to 30.7 ± 5.8 mm/s, = 0.60; COP 25.4 ± 3.1 to 25.3 ± 3.2 mm, = 0.02; COP 20.7 ± 3.3 to 21.1 ± 2.5 mm, = 0.94). Therefore, DS of the plantar flexors enhances postural control during single-leg standing and may be effective for both injury prevention and performance enhancement.
静态拉伸（SS）和动态拉伸（DS）被广泛用作运动前的热身活动。然而，拉伸是否会影响姿势控制仍不清楚。我们比较了单腿站立期间SS和DS对跖屈肌及姿势控制的影响。15名健康的年轻参与者进行了SS、DS或不进行拉伸（对照组）。拉伸条件包括每组持续30秒的四组。对照条件是站立休息210秒。在每次干预前后，使用测力板测量压力中心（COP）位移，以评估单腿站立任务期间的姿势控制。计算了COP面积、COP速度以及前后（COP）和内外侧（COP）范围。DS使COP范围（21.5±4.1至19.0±2.5毫米；P = 0.02）、COP速度（33.8±7.6至29.8±6.5毫米/秒；P < 0.01）和COP面积（498.6±148.3至393.3±101.1毫米；P < 0.01）显著降低，而SS的COP参数没有变化（COP面积457.2±108.3至477.8±106.1毫米，P = 0.49；COP速度31.2±4.2至30.7±5.8毫米/秒，P = 0.60；COP 25.4±3.1至25.3±3.2毫米，P = 0.02；COP 20.7±3.3至21.1±2.5毫米，P = 0.94）。因此，跖屈肌的DS可增强单腿站立期间的姿势控制，并且可能对预防损伤和提高运动表现均有效。
