Maximal Oxygen Consumption
I’m working on a kinesiology multi-part question and need a sample draft to help me study.
I will provide for you two articles that you need to read to help you solve the worksheet and also excel data that you will need to use for completing part 15.2 in the worksheet. Let me know if you have any question.
You need to complete the worksheet that has two forms for 15.1 and 15.2, and also there is a multiple questions that you need to answer for part 15.3 and I will provide for you that box with the questions that needs to be answered for 15.3. I will provide powerpoint to better understand the material.
These are information on how to do the forms 15.1 and 15.2:
1- On form 15.1, the data is provided for you. You will need to calculate VE STPD, Abs VO2, Rel VO2, % E from fat and carbohydrates, E in kcal/min. You will also need to determine which criteria for max were met, what the absolute and relative VO2 max are and what aerobic fitness category their max falls within.
2- on form 15.2 you can use excel that is provided for you.You will need to calculate Abs VO2, Rel VO2, % E from fat and carbohydrates, E in kcal/min for each of the 11 minutes. You will also need to determine which criteria for max were met, what the absolute and relative VO2 max are and what aerobic fitness category their max falls within.
VO2 Max
KIN 330
Learning objectives
To describe what VO2 max is and why it is measured.
Be familiar with values for VO2 max .
To describe how we verify achievement of VO2 max .
To explain the physiological factors that contribute to VO2 max .
To broadly understand how to increase VO2 max .
VO2 max
AKA: VO2 max, maximal oxygen consumption, maximal oxygen uptake, maximal aerobic power, aerobic capacity
The greatest amount of O2 that can be utilized per minute to produce ATP during large muscle activity
Occurs at the point in incremental exercise when VO2 plateaus even though workload increases
VO2 max (cont.)
Determined during incremental exercise test
VO2 is a linear function of workload until maximal levels are achieved (VO2 max)
Represents the maximal rate of aerobic re-synthesis of ATP
CV system’s ability to deliver O2
muscle’s ability to use O2

Criteria for VO2 max

Gold Standard = plateau in VO2 even with increase in work rate
If a plateau in O2 consumption is not achieved…secondary criteria include:
Age-predicted max heart rate (+/- 10 beats/min)
Blood lactate concentration of 8 mM or higher
RER of 1.15 or higher
****Research reveals that these criterial do not always “prove” that VO2 max has been reached
5
ACSM Guidelines- VO2 max values
1 MET = 3.5 ml/kg/min

Why do we measure?
Cardiovascular fitness
One of the main determinants of aerobic performance
Indicator of cardiovascular health
Physiological Factors that Contribute to VO2 max
How to increase your VO2 max
Unfit:
moderate intensity for 30 minutes or more minutes at least 3 days/week
Fit:
vigorous intensity for 20 or more minutes at least 3 days/week
Summary
Important measure and marker of health and performance.
