伸展运动可以增加关节的活动范围，但其急性影响会降低肌肉力量。然而，这可能取决于人群或拉伸方式。本研究的目的是比较静态拉伸与弹道拉伸对芭蕾舞演员和接受阻力训练的女性力量和肌肉疲劳的急性影响。 15 名接受过阻力训练的女性（年龄 23.8 +/- 1.80 岁，体重 67.47 +/- 7.77 公斤，身高 168.30 +/- 5.53 厘米）和 12 名芭蕾舞演员（年龄 22.8 +/- 3.04 岁，体重 58.67 +/- 5.65 公斤，身高 168.00 +/- 7.69 厘米）进行了 5 次表演。测试的天数。第一天是对照（无拉伸），而其他 4 天是按平衡顺序进行静态或弹道拉伸。还进行了运动范围、力量和疲劳测试。与对照组（113.059 +/- 3.25 N.m）相比，两组在静态（102.71 +/- 2.67 N.m）和弹道拉伸（99.49 +/- 2.61 N.m）后腘绳肌力量显着下降，而股四头肌力量没有变化。对于疲劳，只有芭蕾舞演员表现出从控制（71.79 +/- 4.88%）到弹道（65.65 6 8.19%）的下降，但与静态（65.01 +/- 12.29%）没有差异。这些发现表明，对于芭蕾舞演员和接受阻力训练的女性来说，拉伸会降低腿筋的力量，而且拉伸模式之间没有差异。然而，弹道拉伸只能减少芭蕾舞演员的肌肉疲劳，但不能减少接受阻力训练的女性的肌肉疲劳。因此，力量训练前不宜进行拉伸。然而，弹道拉伸可能会减少芭蕾舞演员的急性肌肉疲劳。
Stretching is used to increase joint range of motion, but the acute effects can decrease muscle strength. However, this may depend on the population or mode of stretching. The purpose of this study was to compare the acute effects of static vs. ballistic stretching on strength and muscular fatigue between ballet dancers and resistance-trained women. Fifteen resistance-trained women (age 23.8 +/- 1.80 years, mass 67.47 +/- 7.77 kg, height 168.30 +/- 5.53 cm) and 12 ballet dancers (age 22.8 +/- 3.04 years, mass 58.67 +/- 5.65 kg, height 168.00 +/- 7.69 cm) performed 5 days of testing. The first day was control (no stretching), whereas the other 4 days were static or ballistic stretching in a counterbalanced order. Range of motion, strength, and fatigue tests were also performed. Both groups demonstrated a significant decrease in hamstrings strength after static (102.71 +/- 2.67 N.m) and ballistic stretching (99.49 +/- 2.61 N.m) compared with control (113.059 +/- 3.25 N.m), with no changes in quadriceps strength. For fatigue, only ballet dancers demonstrated a decrease from control (71.79 +/- 4.88%) to ballistic (65.65 6 8.19%), but no difference with static (65.01 +/- 12.29%). These findings suggest that stretching decreases hamstrings strength similarly in ballet dancers and resistance-trained women, with no differences between modes of stretching. However, ballistic stretching only decreased muscular fatigue in ballet dancers, but not in resistance-trained women. Therefore, no stretching should be performed before strength performance. However, ballistic stretching may decrease acute muscular fatigue in ballet dancers.
