We studied respiratory mechanics in young volunteers before and after 5-wk training programs limited to the ventilatory muscles. Four strength trainers (S) performed repeated static maximum inspiratory and expiratory maneuvers against obstructed airways. Four endurance trainers (E) performed voluntary normocarbic hyperpnea to exhaustion. Subjects spent 30-45 min each day in these exercises, 5 days a week. Four control subjects (C) did no training. We attempted to minimize the effect of learning. S increased pressure maximums by about 55%, but vital capacity and total lung capacity by only about 4%. Initially all subjects could sustain hyperpnea at about 81% of their control 15-s maximum voluntary ventilation (MVV) for 15 min; E increased this to about 96% and increased their MVV by 14% as well. No other statistically significant changes were recognized in any group. We conclude that ventilatory muscle strength or endurance can be specifically increased by appropriate ventilatory muscle training programs.
我们研究了年轻志愿者在进行为期5周、仅限于呼吸肌的训练计划前后的呼吸力学情况。四名力量训练者（S组）针对阻塞气道进行反复的静态最大吸气和呼气动作。四名耐力训练者（E组）进行自愿性的正常碳酸血症过度通气直至力竭。受试者每天花30 - 45分钟进行这些练习，每周5天。四名对照受试者（C组）不进行训练。我们试图将学习效应降至最低。S组的最大压力增加了约55%，但肺活量和肺总量仅增加了约4%。最初，所有受试者都能以其对照15秒最大自主通气量（MVV）的约81%维持过度通气15分钟；E组将此提高到约96%，其MVV也增加了14%。在任何组中均未发现其他具有统计学意义的变化。我们得出结论，通过适当的呼吸肌训练计划可以特异性地增强呼吸肌力量或耐力。
