摘要
心脏泵血能力是VO2max限定因素的观点早已提出,60~70年代此观点受到了肌肉适应性研究结果的挑战。肌肉血管床和线粒体数量随训练可有所增加,这些适应被认为是VO2max提高的前提条件。此后,由于令人信服的研究结果的展示,偏移的观点又回转到心肺机能是氧投递的限定因素上来。
Initially the pump capacity of the heart was proposed as critical factor to VO_(2max), This view unchallenged until result on the plasticity of muscle came about in 1960-70s, The capollary bed of muscle and its mitochondral volumes can be enhanced with training, These adaptations were then suggested to be prerequisites for VO_(2max) to become enhanced. The pendulum is slowly swinging back again toward heart and lungs setting the upper limit for oxygen transport.
