Marked Increase in Urinary Bicarbonate and pH Caused by Heavy Muscular Exercise with Dynamic Knee Extension

摘要: In order to estimate the physiological responses heavy muscular exercise with dynamic knee extension, levels of urinary variables such as bicarbonate, pH and blood lactate were studied before after exercise. Nine male volleyball players aged 19 or 20 years involved in present study. They performed 10%, 30% 80% 1 repetition maximum (RM) extension. The bicarbonate did not change for 2.5 hours cessation 10% RM load, compared baseline levels. When loading was given, moderately increased hours. both immediately exercise, Levels extensively within minute subjects but no significant increase seen load. changes could be explained by continuous production CO2 tissues a submaximal load where excess postexercise oxygen consumption is accelerated. It also possible that liver muscle aerobically metabolized cause these changes. suggested measurement may useful estimation events body loading.
