VO2 max Lab Report

1. Bike subject
Criteria for valid max| Value achieved by subject| Criteria met?| HR is 90% of age predicted max| 185 BPM| Yes|
VO2 plateaus (an increase of <0.15L/min with an increase in exercise intensity)| >.15L/min| No| An RER value of 1.1| 1.15| Yes|
Bike subject: shows which criteria was/was not met during test.
Treadmill subject
Criteria for valid max| Value achieved by subject| Criteria met?| HR is 90% of age predicted max| 198 BPM| Yes|
VO2 plateaus (an increase of <0.15L/min with an increase in exercise intensity)| >.15L/min| No| An RER value of 1.1| 1.08| For this lab, yes|
Treadmill subject: shows which criteria was/was not met during test.

2. Heart rate should correspond closely with VO2. At 80% of your maximum heart rate, VO2 max levels should be 75%.

Subject 1 Bike: shows the relationship between HR (BPM) and VO2 (L/Min.)

Subject 2 Treadmill: shows the relationship between HR (BPM) and VO2 (L/Min.) 3. Subject 1 had a predicted VO2 max of 52.01. The range of values were 44.21 ml/kg/m - 59.81 ml/kg/m. Subject 2 had a predicted VO2 max of 34.78 ml/kg/m. The range of values were 29.56 ml/kg/m - 39.99 ml/kg/m. 4. Percentage of max HR is a good predictor of VO2 max. Generally, your maximum HR will represent your maximum VO2 levels, or very close. At 80 percent of your maximum HR, your VO2 levels should be 75 percent. This makes sense physiologically because an increase in VO2 should cause an increase in HR. Both subjects met the necessary criteria for a valid max test. This means that the accuracy was good as well as the ability to interpret the results. Look at your results in question #4. Did the actual max fit within the range calculated from the predictive test? Based on your results, what can you conclude about the accuracy of the prediction test?VO2 max has a...
