While static stretch (SS), proprioceptive neuromuscular facilitation (PNF) and oscillatory physiological mobilization techniques are documented to have positive effects on a range of motion (ROM), there are no reports on the effect of dynamic oscillatory stretching (DOS), a technique that combines these three techniques, on hamstring extensibility.
To determine whether DOS improves hamstring extensibility and stretch tolerance to a greater degree than SS in asymptomatic young participants.
Randomized Controlled Trial.
Sixty participants (47 females, 13 males, mean age 22 ± 1 years, height 166 ± 6 centimeters, body mass 67.6 ± 9.7 kg) completed a passive straight leg (SLR) to establish hamstring extensibility and stretch tolerance as perceived by participants, using a visual analogue scale (VAS). Participants were randomly assigned to one of two treatment groups (SS or DOS) or a placebo control (20 per group). Tests were repeated immediately following and one hour after each intervention. Data were assessed using a two-way repeated measure analysis of variance (ANOVA) and test.
Immediately post-intervention, there was a significant improvement in the hamstring extensibility as measured by the SLR in both the SS and DOS groups, with the DOS group exhibiting a significantly greater increase than the SS group (Control 73 ± 12°, SS 86 ± 8°, DOS 94 ± 11°, p < 0.001). One hour post-intervention, hamstring extensibility in the DOS group remained elevated, while the SS group no longer differed from the control group (Control 73 ± 12°, SS 80 ± 8°, DOS 89 ± 12°, p = 0.001). Furthermore, the stretch tolerance remained significantly elevated for the SS group, but there was no difference between the control and DOS groups, (Control 4.6 ± 1.3, SS 5.9 ± 0.8, DOS 4.3 ± 1.0 AU, p < 0.001).
DOS was more effective than SS at achieving an immediate increase in hamstring extensibility, and DOS demonstrated an increased stretch tolerance one-hour post-intervention.

虽然静态拉伸（SS）、本体感觉神经肌肉促进法（PNF）和振荡性生理松动技术已被证明对关节活动范围（ROM）有积极影响，但尚无关于动态振荡拉伸（DOS，一种结合了这三种技术的方法）对腘绳肌伸展性影响的报道。
确定在无症状的年轻参与者中，动态振荡拉伸（DOS）是否比静态拉伸（SS）能更大程度地提高腘绳肌伸展性和拉伸耐受性。
随机对照试验。
60名参与者（47名女性，13名男性，平均年龄22±1岁，身高166±6厘米，体重67.6±9.7千克）完成被动直腿抬高（SLR），使用视觉模拟量表（VAS）确定参与者所感知的腘绳肌伸展性和拉伸耐受性。参与者被随机分配到两个治疗组（SS或DOS）之一或一个安慰剂对照组（每组20人）。在每次干预后立即以及干预后一小时重复进行测试。使用双向重复测量方差分析（ANOVA）和检验对数据进行评估。
干预后即刻，通过SLR测量，SS组和DOS组腘绳肌伸展性均有显著改善，DOS组的增加幅度显著大于SS组（对照组73±12°，SS组86±8°，DOS组94±11°，p<0.001）。干预后一小时，DOS组的腘绳肌伸展性仍保持升高，而SS组与对照组不再有差异（对照组73±12°，SS组80±8°，DOS组89±12°，p = 0.001）。此外，SS组的拉伸耐受性仍显著升高，但对照组和DOS组之间没有差异（对照组4.6±1.3，SS组5.9±0.8，DOS组4.3±1.0 AU，p<0.001）。
在使腘绳肌伸展性立即增加方面，DOS比SS更有效，且DOS在干预后一小时显示出更高的拉伸耐受性。
