Exam 1

Question 1

What is exercise physiology?

Answer 1

The study of exercise on the function of tissues, organs, and systems.
> also, prevention of disease or rehabilitation from chronic illness

Question 2

What are the two primary concerns of exercise physiology?

Answer 2

1. how the body responds to the acute stress of a single bout of exercise (acute exercise)
2. How the body responds to the chronic stress of repeated bouts of exercise (training)

Question 3

Observational study

Answer 3

> Researchers do not manipulate experimental variables
subjects divided into subgroups based on prior history of exercise
• No intervention: example, prior history of exercise
• measure a daily life variable

Question 4

Experimental study

Answer 4

Researchers manipulate experimental variables (independent variables)
> subjects are randomly assigned to two or more groups or conditions
> intervention
> example: give exercise at a certain intensity then measure variables

Question 5

Research settings

Answer 5

> laboratory research
field research

Question 6

Laboratory research benefits

Answer 6

• Easy to mimic or replicate
• can control for variables

Question 7

Field research benefits

Answer 7

• More authentic/real word situation
• can affects results
• can’t control for all variables such as weather

Question 8

Ergometers used in the measurement of human work output and power

Answer 8

Bench step, cycle ergometers, treadmill, arm ergometers

Question 9

Others ergometers besides main ones:

Answer 9

Tethered swimming, swimming flume, rowing machine, sup engometer, and Kayak ergometer

Question 10

How do we mainly evaluate muscular strength?

Answer 10

Dynamometer (#1), cable tensiometer, hand dynamometer, Isokinetic dynamometer

Question 11

Why is it hard to quantify power on a treadmill?

Answer 11

Because its hard to account for lateral movement (our internal spring)

Question 12

Components of effective physiological testing

Answer 12

•
• physiological variables tested should be relevant to the sport
• tests should be sport-specific
• equipment must be calibrated ( precision, validity, accuracy)
• Testing procedures should be repeated at regular intervals
• tests should be valid and reliable

Question 13

Varying environmental, behavioral, and physiological factors can do what to the body?

Answer 13

Alter the body’s response to an acute bout of exercise.
Examples: temp, humidity, noise level, food intake, sleep

Question 14

What conditions under which research participants are monitored?

Answer 14

At rest and during exercise = both must be carefully controlled

Question 15

Line graphs

Answer 15

Used when both the iv and the dv are quantitative (#’s) - time series data

Question 16

Bar graphs

Answer 16

Best used to compare values across categories (groups).

Question 17

What tests are used to compare two means?

Answer 17

Dependent (paired) t-test and independent t-test

Question 18

What is a dependent t-test?

Answer 18

When same subjects are being tested twice (ex: before and after exercise program)
> there is one independent variable
> comparing two means

Question 19

What is an independent t-test?

Answer 19

When two independent groups ( ex: control group and exercise group)
> one independent variable
> two means

Question 20

What tests compare multiple means?

Answer 20

> repeated measures analysis of variance (rm-anova)
one way ANOVA
factorial ANOVA

Question 21

What is a repeated measures analysis of variance?

Answer 21

Scare subjects being tested multiple times ( ex: once a week for 5 weeks )

Question 22

One way ANOVA?

Answer 22

Three or more independent groups (control group, low intensity exercise group, moderate intensity exercise group, high intensity exercise group) 
> One independent variable
> Comparing multiple means

Question 23

What is a factorial ANOVA?

Answer 23

Four or more independent groups
> Two or more independent variables
> Comparing multiple means
