Vo2 Max Test Lab Report

3. All three subjects attained their oxygen consumption (VO2) max. Each subject was able to pass 3 criteria to attain a VO2 max. To begin with subject 1 attained their VO2 max because the individual respiratory exchange ratio (RER) was greater than 1.15. As shown in table 1, the subject’s max RER is 1.2, which is greater than 1.15. Also, the rating of perceived exertion (RPE) was greater 17, as shown in table 1 the subject’s RPE is 20. Finally, the post VO2 max blood lactate level was 15.2, the requirement is 8. Therefore, subject 1 attained their VO2 max test. In addition, subject 2 attained their VO2 max because the subject had a heart rate that was within the age predicted heart rate their age predicted heart rate, as shown in table 2, the …show more content…
Finally, the RPE of subject 2 is 20, which meets the criteria to be above an RPE of 17. Therefore, subject 2 met the 3 criteria to attain a VO2 max. Subject 3 also attained a VO2 max. To begin with, the subject had a heart rate that was within the age predicted heart rate their age predicted heart rate, as shown in table 3, the subject’s heart rate was 190, which is within age predicted heart rate (199 beats per minute) with a plus/minus12 beats per minute variable. Additionally, as shown in table 3, subject 3 RPE is 20, exceeding the criteria of an RPE of 17. Finally, the post VO2 max blood lactate level for subject 3 was 14.2, exceeding the requirement of a blood lactate level of 8. Therefore, subject 3 attained their VO2 …show more content…
Figures attached. Subject 1 did reach ventilatory threshold (VE), as shown in figure 4, subject 1 had a steep increase of VE at a heart rate of 147 beats per minute. Subject 2 reached a ventilatory threshold, as shown in figure 8, subject 2 had a steep increase of VE at a heart rate of 120 beats per minute. Finally, subject 3 did reach a ventilatory threshold, as shown in figure 12, subject 3 had a steep increase of VE at a heart rate of 179 beats per minute. Ventilatory threshold increases as workload increase because there is an increase in blood lactate. Furthermore, the latic acid dissociates into a lactate and hydrogen ions, ultimately forming carbonic acid by a combination of hydrogen ion and bicarbonate. Additionally, carbonic acid dissociates into water and carbon dioxide. The carbon dioxide in the blood leads to an increase expiration of ventilation. Therefore, ventilatory threshold increases as workload increases because the accumulation of carbon
