Beside the increase in O2 and CO2, there is a compromise of lactate acid and acid- base balance from a high intensity exercise. The factors that avoid this change in the homeostatic limits are PO2 and PCO2, and pH. Which are maintained form increase in oxygen delivery to the alveoli and CO2 exhalation from the body (King, 2018). Acid- Base balance are affected by hydrogen ions which are formed from the lost of electrons. When a molecule releases hydrogen ion it is determined as acid, and when it is bind with hydrogen ion it is a base. Hydrogen ion expressed in the blood is represented as pH levels, which the homeostatic level should be a pH of 7.40 ± .02. Acid- Base balance is concerned with the hydrogen ion in the blood as it …show more content…
By knowing the lactate levels in the body is helpful in determining the efficient work rate to be able to obtain the full benefits. As well to track the ventilation to be able to determine if its able to work as a buffer system to remove hydrogen ions from the blood. The ventilation will be collected the progressive test and the constant-load test on the cycle ergometer recording the VO2 , ambient room temperature and pressure (VE (ATPS)), frequency of breaths rate of perceive exertion (RPE) and heart rate (HR) to calculate the VE (BTPS) and the tidal volume. While lactate levels will be collected by the same progressive test and constant-load test except, instead of the TV it will be the lactate taken form blood collected from a finger pricks after each increment. Accumulation of lactate occurs form hydrogen ions caused by CO2 in order to remove blood lactate levels form the blood from the hydrogen ion influence on carotid bodies. Indicating that ventilation threshold is associated with lactate threshold (King, 2018). From this understanding, it is hypothesized that the ventilation threshold and the lactate threshold will occur during the same
