Inspiratory capacity is the amount of air taken in during a deep breath, while residual volume is the amount of air left in the lungs after forceful respiration. Explain why VC does not change with exercise. It does not store any personal data. Materials and Methods 1. Explain why slow, deep breathing ventilates the alveoli better than rapid, shallow breathing. Why is a higher heart rate during the recovery period equated with a lower level of fitness? In healthy individuals, exercise produces either a mild bronchodilatation, facilitating an increase in airflow without a significant increase in airway resistance and the work of breathing, 1 or has no effect.

When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. Why is it that blood flowing through the chambers within the heart cannot supply sufficient oxygen or remove enough carbon dioxide from the myocardium? During exercise, there is an increase in demand for oxygen which leads to a decrease in IRV. Explain why VC does not change with exercise.

Why do bodybuilders have sagging muscles when they stop working out? Which cardiorespiratory parameters change during the transition from rest to exercise, and which of these can exhibit plasticity due to aerobic training? Cellular respiration creates energy from food either with or without oxygen. The rate is dependent on the tidal volume, and the value is about 6000 ml per minute. What happens in the lungs when the diaphragm relaxes? With the increase in oxygen consumption, a greater increase in blood flow occurs. How can you accomplish this, and will you benefit from.
