Exercise Physiology Practical

If the professor asks you to set up the monark bike at 100 watts, 50 rpms; what KP should he be on?

2 KP (watts doesnt matter). Always multiply rpms by KP to get watts.

Identify two skills learned in the lab - explain why be short and brief

One skill I learned was how to take blood pressure - I liked learning this because I want to go to medical school and I am doing EMT this summer. This is a basic but essential skill that will be necessary throughout my career.

Another skill I learned is how to run a VO2 max test. I thought this was cool to learn because this is something you can do at home if you have a treadmill. It doesnt require a lot of equipment and it gives you cool results to analyze.

Define blood pressure

Blood pressure is the force exerted by the blood against the arterial walls

How is systolic blood pressure determined?

It is determined by the first korotkoff sound

How is diastolic blood pressure determined?

It is determined by the disappearance of the korotkoff sound

Describe the calibration of the metabolic cart

There is 2 calibrations.

1. Flow meter calibration - uses a 3.0L syringe to calibrate the volume of air

2. Gas calibration - compares the room air to the standard gases in the tank such as nitrogen, oxygen, and carbon dioxide

Define VO2 oxygen consumption

VO2 is the rate of oxygen consumption by the body using the FICK equation. FICK is cardiac output x AVO2 difference.

Explain how oxygen consumption is measured

It is measured by indirect calorimetry. This is when we perform a graded exercise test (aka VO2 max test) on the treadmill

Identify one muscular fitness test. Explain purpose and what it measures.

1RM - 1 Repetition Max Test

Purpose - to determine an individuals maximum dynamic strength

We are measuring absolute and relative strength

Identify one body composition assessment and explain the rationale - provide one pro and one con of the assessment

Dexa assessment - scans your body through an xray machine and provides information about % body fat, body mass, lean mass, and bone mineral density

Pro - none of the other tests mentioned can measure bon mineral density, this machine is unique
Con - you need to be certified and go through a training on the specific Dexa machine you are using
