Final answer:
Cardiorespiratory training includes aerobic and anaerobic exercises aimed at enhancing cardiovascular and pulmonary function. Hyperpnea is the increase in breathing depth and rate during exercise, in contrast to hyperventilation, where there is an excessive breathing rate. Acclimatization helps the body adjust to high altitudes by increasing breathing rate and red blood cell count.
Step-by-step explanation:
Cardiorespiratory training refers to exercises that aim to improve the efficiency of the cardiovascular and respiratory systems in absorbing and transporting oxygen to the muscles that are engaged in physical activity. Its purpose is to enhance overall fitness levels, specifically endurance and cardiovascular health. These exercises can typically be divided into aerobic (like running or swimming, which use oxygen to generate energy and can be sustained) and anaerobic (like sprinting, which do not rely on oxygen and are intense but short in duration).
Hyperpnea is an increase in the depth and rate of breathing and usually occurs during exercise, while hyperventilation is an increase in breathing that is disproportionate to the production of carbon dioxide, and it can lead to a decrease in blood carbon dioxide levels. Exercise enhances the respiratory system's function by boosting the lungs' capacity to take in air and improving the efficiency of gas exchange between the lungs and the blood.
High altitude impacts the respiratory system by reducing the concentration of oxygen in the air, which can initially impair the ability to perform physical tasks and may lead to altitude sickness. The process called acclimatization involves physiological adjustments the body makes to adapt to the lower oxygen levels at high altitudes, such as increasing ventilation and the number of circulating red blood cells to transport more oxygen.
