Significance of post-exercise increment of urinary bicarbonate and pH in subjects loaded with submaximal cycling exercise

摘要: We studied the changes in urinary bicarbonate, pH and some physical parameters such as minute ventilation (VE), oxygen consumption (VO2), respiratory carbon dioxide (VCO2), heart rate, blood pressure, lactate, before after submaximal exercise. Six male subjects aged 28-33 years were involved study. They performed incremental exercise test using a bicycle ergometer until exhaustion. Levels of VE, VO2, VCO2, pressure increased continuously with an increase cycling intensity. These markedly decreased reached baseline levels within 5-10 minutes termination According to intensity, lactate during exercise, but return level was retarded. Urinary bicarbonate range those at 0 time (baseline levels) from beginning 30 However, they began abruptly about continued extensively for 2 hours thereafter. Such marked seemed be correlated aerobic metabolism muscles, liver, kidney, finally producing CO2. It also suggested that measurement may useful estimation physiological body loading.
