lab 9
Identify the VO2 max from this individual. (The conditional formatting options in Excel allow us to color code low values as green through high values at red.Data from min 14:39 / 14:59 appear to be a potential VO2 max but there is a drastic dip and peak that give the impression that there was an averaging error or processing delay.)
The respiratory exchange ratio (RER) provides information about the fuel source being utilized during exercise. What columns provide fuel source information? How are they changing as workload is increasing? What is the RER at the end of the exercise portion of the test?
Plot VE/VO2 from 7:59 to 18:19.Look at the shape of the curve. Near the end of the exercise test there is a change in the slope of the line.This is an indication of the anaerobic threshold.What does this mean?
What is the max METs achieved?Is this MET variable from the individual’s measured METs or estimated METs? How do you know?Based on Byrne et al., 2005, can you guess what the MET value should be for this 18-22 year old male?
lab 11
1RM Chest and Leg Press
How many warm-up sets should be completed?
How many 1RM attempts should be completed?
Tim completed his three warm-up sets and then successfully lifted 160lbs, and 220lbs, but failed to lift 260lbs.How can I guarantee that I will find the true 1RM (within 10 lbs) in the next two attempts?
Besides safety, what is the purpose of conducting warm-up sets?
If the person I am testing is concerned about lifting a heavy weight for a 1RM test, what alternative could I offer that would allow me to identify their 1RM?
If you conduct a test using a machine instead of free weights, how can I ensure that the tests will be comparable?
Push-up
What cadence does the participant need to follow for this protocol?
What does the person leading the testing need to observe to consider a repetition of the push-up complete and count it towards the total?
When does the test end?
Standing Long Jump
How is the distance for a jump calculated?What two points are needed to determine the distance?
How many attempts are allowed for an individual?
What counts as a successful attempt?

Lab 17: Converting Bruce Protocol from Treadmill to Upper Body Cycle Ergometer
Instructions: Open the Google Drive Sheet and download it to Excel, make a conversion to VO2 at each workload, convert VO2 to Watt if possible. You may need to do some reading to find out if this is possible.
Bruce Treadmill Protocol:
| Stage | Speed (mph) | Treadmill Grade (slope) | End of Stage (Time) |
| 1 | 1.7 | 10 | 3 |

| 3 | 3.4 | 14 | 9 |
| 4 | 4.2 | 16 | 12 |
| 5 | 5 | 18 | 15 |
| 6 | 5.5 | 20 | 18 |
| 7 | 6 | 22 | 21 |
