射击实验表明,射手在实弹射击前及射击过程中,由于中枢神经兴奋,呼吸节律加快,从而导致射击命中概率降低。人在呼吸运动中,整个腹部呈现显著的起伏(扩张和收缩),而且呼吸节律越快,呼吸越深,起伏就越大。而通常射手在卧姿射击时,往往全身俯地,使枪和身体合为一体。尤其是步、机枪和火箭筒特 Shooting experiments show that the archer was firing at the firing and before the firing process, due to the excitement of the central nervous system, breathing rhythm to speed up, resulting in reduced probability of shooting hit. People in the respiratory movement, the abdomen showed significant ups and downs (expansion and contraction), and the faster breathing rhythm, breathing deeper, the greater the ups and downs. Shooter usually shot in the prone position, the body is often bent, the gun and the body together. Especially the steps, machine guns and rocket special
