An experiment was performed in which a healthy subject engaged in three exercises, with instrumentation in place to control and measure a variety of physiological variables. The data collected are shown in the table below. Examine the data, and without doing any calculations determine the intensity levels of the different exercises. Exercise Exercise #1 Exercise #2 Exercise #3 Respiratory rate 22 breaths/min 25 breaths/min 18 breaths/min Tidal volume 700 mL/breath 610 mL/breath 850 mL/breath Dead space 130 mL 130 mL 130 mL Heart rate 153 beats/min 136 beats/min 144 beats/min Cardiac stroke volume 80 mL/beat 90 mL/beat 85 mL/min Systemic artery Pco2 100 mmHg 100 mmHg 100 mmHg Pulmonary artery Po2 40 mmHg 20 mmHg 30 mmHg Hematocrit 45% 45% 45%
