The table shows the increases of respiratory rate, tidal volume, and oxygen uptake for each exercise intens

“As we ascend above sea level, the barometric pressure (Pb) decreases as the weight of the atmosphere becomes less.” (Foss & Keteyian, 1998). At altitudes over 5000 feet (1524meters), the ability to perform physical work is decreased due to hypoxia (lowered PO2). However, physical performance at moderate altitude may sometimes be improved with continued stay at altitude due to the acclimatization process. “This involves (1) increased red blood cell and haemoglobin concentrations, (2) elimination of bicarbonate (HCO3) in the urine, and (3) in those chronically exposed to altitude, tissue level changes. Increased physical fitness alone does not acclimatize the individual to altitude.” Foss & Keteyian (1996). Altitude mainly affects endurance or aerobic activities rather than sprint or anaerobic events. This is because the major problem is hypoxia, which significantly reduces oxygen availability. When anaerobic performance is not significantly influenced, the lactate response is blunted at altitude. Training at altitude might enhance performance at sea level but well controlled studies have not been performed to document any improv
