Monitoring the peripheral blood flow oxygen saturation in patients undergoing hemodialysis or in intensive care unit is the clinical application of oxyhemoglobin saturation by pulse oximetry (SPO2), which is easy to use and non-invasive. The patients were supplied with oxygen if their SPO2 drop to abnormal level in order to avoid emergency syndromes such as anoxia or acute respiratory distress syndrome. This study applied the clinical application of SPO2 on endurance training, using the resting values of SPO2 and daily recorded heart rate, to investigate the influence of training intensity on SPO2 and heart rate variances. Purpose: to examine the influence of hypoxia environment (altitude training base, 1906m, average relative oxygen concentration was 16%) by monitoring daily resting SPO2 and Heart rate records on elite distance runners. Methods: monitoring and recording the daily SPO2 and heart rate values before sleep by portable pulse oximetry. Independent-Sample t test and one-way ANOVA were used to analyze difference of altitude training and sea-level training, and the variances of SPO2 and heart rate by training intensity. Results: after 3weeks of altitude training and 3weeks of sea-level training, the daily resting SPO2 and heart rate showed significant differences between altitude and sea-level training (SPO2: 95.39±2.49%, 97.56±1.18%, p＜.05; HRrest: 63.55±8.26bpm, 58.24±6.33bpm, p＜.05), however, there were no influence on two types of training sessions (F value: 0.482, 2.408, p＞.05). Conclusion: in the hypoxia environment, the SPO2 decreased significantly. Subsequently, the physiological compensations such as heart rate, breath and pulmonary exchange ratio increased, which had close effects by environment oxygen saturation. For altitude training, we suggest that, through the daily rest SPO2 and heart rate monitoring, the records could be useful on athletes training program, considering the physiological aspect, and adjust the training intensity.
