Explain why athletes who excel at short sprints probably have fewer slow-twitch fibers in their lower leg muscles. More substantial changes were noted in TP and RR intervals. Emphysema causes alveolar dilation and destruction of alveolar walls, which causes an increase in residual volume with air that cannot be exhaled. That total lung capacity doesn't change much for an individual over time, even with changes to fitness levels. Explain how this can happen, even when ventilation of the lungs increases. 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). Therefore an increase in PCO2 results in an increase in H+ and HCO3- formed. Explain the correlation between physical activity and cardiovascular disease. d irv . VC is the amount of air an individual can exhale after making a maximal inhalation. Inspiratory capacity increased with exercise because of the greater amount of air that could be moved, due to greater tidal volumes. e. It ke. dissociates into H+ and HCO3-.
