The evaluation of the aerobic capacity is of great importance for athletes as well as for patients with cardiac and pulmonary diseases. For objective measurements of cardiorespiratory and metabolic responses heart rate, lactate concentration in capillary blood and ventilatory gas exchange are determined during incremental exercise tests either on different ergometers in a laboratory or under training conditions in the field. Besides the maximal O2-uptake (VO2max) several ventilatory and lactate thresholds have been proposed as reliable values for assessing the aerobic capacity and giving training recommendations. For interpretation of the results the training and nutrional behaviour in the previous days have to be considered as especially the lactat thresholds are influenced by the glycogen content of the muscles. Furthermore, training recommendations cannot always be easily transferred from test to training conditions as these can be very different from each other.
对运动员以及患有心肺疾病的患者而言，评估有氧能力非常重要。为了客观测量心肺和代谢反应，在递增运动测试期间，要在实验室的不同测力计上或在实地训练条件下测定心率、毛细血管血中的乳酸浓度和通气气体交换。除了最大摄氧量（VO2max）外，还提出了几个通气和乳酸阈值，作为评估有氧能力和给出训练建议的可靠值。为了解释结果，必须考虑前几天的训练和营养行为，因为尤其是乳酸阈值会受到肌肉糖原含量的影响。此外，训练建议并不总是能轻易地从测试转移到训练条件，因为两者可能差异很大。
