中长跑持续时间长、消耗大,对心肺功能要求更高。在训练的过程中,重点在于发展心肺功能和肌肉耐酸能力,其中心肺功能的发展是重中之重。而在常规训练中无论是“三氧训练”还是身体素质训练,刺激最多的是心脏功能和躯干肌群,往往忽视了肺功能和呼吸肌的发展。造成了心脏和肺与呼吸肌功能的不匹配,形成“木桶原理”的短板,尤其是忽视了对于青少年肺和呼吸肌敏感期的发展。而肺功能是主要通过发展呼吸肌训练来完成的。所以提高呼吸肌训练很重要。而常规的呼吸吐纳手段 Middle and long distance long duration, costly, higher demands on cardiorespiratory function. In the training process, the focus is on the development of cardiorespiratory function and muscle acid tolerance, and its central pulmonary function development is the most important. In conventional training, whether it is “three oxygen training ” or physical fitness training, the most stimulating heart function and trunk muscles, often neglect the development of lung function and respiratory muscle. Resulting in a mismatch between heart and lung and respiratory muscle function, creating a “barrel principle” of the plate, in particular, ignoring the development of the young lungs and respiratory muscles sensitive period. The lung function is mainly through the development of respiratory muscle training to complete. So to improve respiratory muscle training is very important. Breathing conventional means
