Explain why TLC does not change with exercise. Ventilation rate refers to the condition when the air volume in the lungs is multiplied by the times an individual is breathing. "Emphysema results in increased compliance of the lungs, so that it does not generate enough recoil, making it difficult for the lungs to return to resting volume. Explain, physiologically, how and why active and passive force changes as a muscle is lengthened. the ERV decrease with exercise assuming that the volume of air was exhaled more than being inhaled at the time. Lung volumes are the volume of gas in the lungs at a given time during the respiratory cycle and include tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume. c. Internal intercostals contract. (b) Why are these important to the cardiovascular system? It is further pointed out that the heart is another limiting factor because it determines how much blood and oxygen are supplied to the muscles especially when blood flow exceeds maximal cardiac output (Bassett & Edward, P6- follows guidelines to interpret collected data for heart rate, breathing rate and temperature before and after a standard period of exercise. IC increases with exercise because the body needed more oxygen. How does the size of the lungs affect exercise performance? 1. Inspiratory capacity increased with exercise because of the greater amount of air that could be moved, due to greater tidal volumes. Does expiratory reserve volume decrease during exercise? Explain the change in IC with exercise. This would affect the results because for the endurance-trained athlete, from their training they increase their cardiac output results from a substantial increase in maximal stroke volume. How does residual volume of the lungs change with age? Compare the resting and exercising systemic vascular resistance values and discuss what causes the observed change with exercise. Capillarisation occurs. During the low intensity exercise (Slow 20) the heart rate increases to 107 bpm, which further increases to 130bpm at a higher intensity level (Fast 20). Minute ventilation is the total volume of air inhaled and exhaled each minute. Why does expiratory reserve volume decrease during exercise?
