Influence of buffering capacity on performance in continuous or intermittent endurance exercise

如果一个人不具有高的缓冲能力，以缓冲在短期（高强度）运动或相对较长的（中等强度）连续或间歇运动中积累的乳酸和氢隆恩，则不能实现高水平的工作。因此，在本研究中，我们调查了在连续或间歇运动中的耐力表现与重碳酸盐或非重碳酸盐缓冲能力之间的关系。为此，我们评估了：1）过量CO_2作为碳酸氢盐缓冲能力的指标的可靠性（实验1）不同类型耐力运动成绩与过量CO_2和非碳酸氢盐缓冲能力指标-肌肽浓度的关系结果表明：运动训练对运动员的碳酸氢盐缓冲能力和非碳酸氢盐缓冲能力有显著影响（实验2），运动训练对运动员的碳酸氢盐缓冲能力的影响（实验3） 关于我们 递增负荷运动时的CO_2过量（CO_2 excess），以及连续或间歇性运动时与运动后呼出CO_2和O_2摄入量之差（CO_2-O_2dif）是碳酸氢盐缓冲能力准确可靠的指标。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）和非碳酸氢盐缓冲能力指标（肌肽浓度）是影响短期（高强度）或相对较长时间（中等强度）连续或间歇运动成绩的因素。实验三的结果表明，耐力训练、短跑训练、耐力训练和低氧训练等方法都有可能改善CO_2过剩、CO_2-O_2dlf和肌肽浓度，这表明在提高ATP-PC、LA和O_2能量系统能力的同时，改进的碳酸氢盐或非碳酸氢盐缓冲能力也是关于改进连续或间歇运动中的表现的不应忽视的因素。少

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.
