摘要
学术背景:最大摄氧量通常被认为是决定中长跑和长跑成绩的一个重要的生理学参数。近年来研究结果显示运动强度可能在提高最大摄氧量扮演着重要的作用。目的:就运动强度与最大摄氧量及运动强度诱导的肌体适应机制相关研究做一综述。检索策略:应用计算机检索http://www.ncbi.nlm.nih.gov网站1979-01/2007-07期间的相关文章,检索词为:"trainingintensity,maximaloxygenuptake",限定文章语言种类为English。在检索336篇文献中,含有运动强度与最大摄氧量,运动强度诱导的肌体适应机制等内容文献126篇。文献评价:在126篇文献中,保留近年相关文献31篇文献做进一步分析,其中人体实验21篇,综述、述评、讲座类文献10篇。资料综合:①训练强度在40%～50%最大摄氧量可提高无训者最大摄氧量。②较小的运动强度能够提高最大摄氧量主要取决于起始最大摄氧量。③优秀耐力运动员需要采用高百分比最大摄氧量来提高最大摄氧量。④耐力训练诱导的肌形态的改变,每博输出量的增加,骨骼肌毛细血管增加,肌红蛋白蛋白含量增加,以及Ⅱ型肌纤维抗氧化能力的提高和最大摄氧量增加相关。结论:研究结果显示在95%～100%最大摄氧量运动强度进行训练可有效提高运动者的最大摄氧量。训练强度诱导耐力运动最大摄氧量变化与最大心输出量和最大动静脉氧差有关。
BACKGROUND: The maximal oxygen uptake (VO2max) is always considered as an important physiological determinant of middle- and long-distance running performance. Recently, many studies have shown that the exercise intensity may play an important role in improving the VO2max. OBJECTIVE: To review the research on the exercise intensity and VO2max and the physiological adaptations associated with the exercise intensity. RETRIEVE STRATEGY: The relevant English articles dated from January 1979 to July 2007 were computer-searched in http://www.ncbi.nlm.nih.gov with the

of 'training intensity, maximal oxygen uptake'. Among the 336 collected articles, 126 were about training intensity and VO2max, and training intensity induced adaptation mechanisms. LITERATURE EVALUATION: Among the 126 articles, 31 with related contents were retained including 21 of human experiment, and 10 review, comment, and lecture articles. DATA SYNTHESIS: ①Training intensities of 40%-50% VO2max can increase VO2max substantially in untrained individuals. ②The minimum training intensity that elicits the enhancement of VO2max is highly dependent on the initial VO2max. ③Well trained endurance athletes probably need to train at relative high percentages of VO2max to elicit further increments. ④Myocardial morphological changes induced by endurance training that increase maximal stroke volume, the increased capillarisation of skeletal muscle, myoglobin concentration, and oxidative capacity of type Ⅱ skeletal muscle fibres are adaptations associated with the enhancement of VO2max. CONCLUSION: The results have shown that the training at 95%-100% VO2max may be effective to improve the VO2max. The changes of VO2max associated with the exercise intensity have a relation with the maximal cardiac output and the arterial-mixed venous oxygen difference.
