心率和血乳酸在中长跑训练中的应用

The Application of Heart Rate and Blood Lactate in Middle-term and long-term Running Practice

心率作为反映运动强度和生理负荷量的生理指标以实用性易测性等特点在运动中被普遍应用。但是心率极易受许多因素影响,因此影响到心率监控和评价的可靠性。乳酸是人体供能体系中的一个重要中间产物,运动时乳酸生成和乳酸清除的代谢变化是掌握运动强度的灵敏指标。通过心率与血乳酸结合的新角度提供一种利用无氧阈心率指导运动训练的方法。

The heart rate consider as the reflection of movement intensity and the physiological load is generally applied in the training. But many factors can influent heart rate, so the heart rate monitoring and the appraisal reliability may be influenced. The lactic acid is an important intermediary product in the system of human body energizes, and the lactic acid production and the lactic acid eliminates are the grasp of the keen target of movement intensity. The article provides one new method which union the heart rate and the blood lactic acid from the new angle to use the non- oxygen threshold heart rate to instruct training.
