本文主要对运动中吼声发力的机制和作用进行理论探讨。笔者认为:人体发力都会反射地引起“憋气”。由于此时还要做一系列收腹、收胸动作,使憋气发力时已增高了的肺内压进一步增高,这种骤增的肺内压将冲开声门振动声带,发出吼声。通过对一些大、中学生的观察和对比实验证明;吼声能提高发力效果。分析认为:发力时发出的吼声能兴奋大脑皮质,让限制肌力发展的大脑保护性抑制的“抑制”作用减弱,使力量增加。不仅如此,它还可避免憋气发力对身体的不良影响,在某些项目中还具有战术意义。因此,应提倡吼声发力。
This article mainly discusses the mechanism and function of roar power in sports. I believe that: the human body will reflect the cause of “suffocation.” Because at this time but also to do a series of abdomen, closing the chest action, so that the pressure has been increased when the breath of the lungs further increased intrapulmonary pressure, this surge of lung pressure will open the glottis vibration vocal cords, roar. Through the observation of some large and middle school students and comparative experiments prove that the roar can improve the hair power effect. The analysis shows that: the roar issued when the hair force can excite the cerebral cortex, so that the inhibition of the development of brains inhibit the “inhibition” effect weakened, so that the power increase. Not only that, it also avoids the adverse effects of suffocation on the body, in some projects also has tactical significance. Therefore, roar should be promoted.
