If an individual does not possess a high capacity to buffer lactic acid and hydrogen lons accumulated during short-term (high intensity) exercise or relatively longer (medium intensity) continuous or intermittent exercise, a high level of work can not be achieved. Therefore, in this study we investigated the relationship between endurance performance during continuous or intermittent exercise and bicarbonate or non-bicarbonate buffering capacity. To do this we evaluated, 1) the reliability of excess- C0_2 as an indicator of bicarbonate buffering capacity (Experiment 1), 2) the -relationship between various types of endurance exercise performance and excess CO_2 as well as- carnosine concentration, which is an indicator of non-bicarbonate buffering capacity (Experiment 2), and 3) the effect of various types of training on bicarbonate or non-bicarbonate buffering capacity (Experiment 3).The results of Experiment 1 showed that excess CO_2 measured until the point of maximal oxygen uptake … More during incremental exercise (CO_2 excess), and also excess CO_2 measured as the difference in the amount of expired CO_2 and O_2 intake(CO_2-O_2dif) during and after continuous or intermittent exercise are accurate and reliable indicators of bicarbonate buffering capacity. The results of Experiment 2 showed that the bicarbonate buffering capacity indicators (CO_2 excess and CO_2-CO_2dif) , and also the non-bicarbonate buffering capacity indicator (carnosine concentration) are influencing factors on performance during short-term exercise (high intensity) or also relatively longer (medium intensity) continuous or intermittent exercise. The results of Experiment 3 showed that it is possible that CO_2excess, CO_2-O_2dlf and carnosine concentration may be improved by such methods as resistance training, sprint training, endurance training and hypoxic training.The aboved results showed that as well as improvements in ATP-PC, LA, andO_2 energy system capacity, an improved bicarbonate or non-bicarbonate buffering capacity is also a factor that should not be ignored in regard to improving performance in continuous or intermittent exercise.

如果一个人在短期（高强度）运动或相对较长时间（中等强度）的连续或间歇运动中积累的乳酸和氢气没有很高的缓冲能力，就无法实现高水平的工作。因此，在这项研究中，我们调查了在连续或间歇运动中耐力表现与碳酸氢盐或非碳酸氢盐缓冲能力之间的关系。为此，我们评估了：1)过量二氧化碳作为碳酸氢盐缓冲能力指标的可靠性（实验1）；2)不同类型耐力运动表现与过量二氧化碳和-肌肽浓度（非碳酸氢盐缓冲能力指标）之间的关系（实验2）；3)不同类型训练对碳酸氢盐或非碳酸氢盐缓冲能力的影响（实验3）。实验1的结果表明，在增量运动中测量到最大摄氧量点的CO_2过量（CO_2过量），以及在连续或间歇运动中和运动后测量的呼气CO_2与吸入O_2的差值（CO_2- o_2dif）的过量CO_2是准确可靠的碳酸氢盐缓冲能力指标。实验2的结果表明，碳酸氢盐缓冲能力指标（CO_2过量和CO_2- co_2dif）以及非碳酸氢盐缓冲能力指标（肌肽浓度）是短期运动（高强度）或较长时间（中强度）连续或间歇运动中表现的影响因素。实验3的结果表明，阻力训练、短跑训练、耐力训练和低氧训练等方法都有可能改善CO_2excess、CO_2-O_2dlf和肌肽浓度。上述结果表明，在提高ATP-PC、LA和do_2能量系统能力的同时，提高碳酸氢盐或非碳酸氢盐缓冲能力也是提高连续或间歇运动成绩不可忽视的因素。少
