Question 2

Aerobic power

Answer 2

The maximum rate at which an athlete can produce energy through the oxidation of energy sources (carbohydrates, fats, and proteins) - also called aerobic capacity

Question 3

Agility

Answer 3

A rapid, whole-body, change of direction or speed in response to a sports-specific stimulus

Question 4

Anaerobic capacity

Answer 4

Maximal rate of energy production by the combined phosphagen and anaerobic glycolytic systems for moderate-duration activities

Question 8

Athletic profile

Answer 8

A group of tests related to sport-specific abilities that are important for quality performance in a sport or sport position

Question 9

Balance

Answer 9

The ability to maintain static and dynamic equilibrium or the ability to maintain the body’s center of gravity over its base of support

Question 10

Body composition

Answer 10

The relative proportion by weight of fat and lean tissue

Question 11

Central tendency

Answer 11

Values about which the data tend to cluster

Question 12

Descriptive statistics

Answer 12

Statistics that summarize or describe a large group of data

Question 13

Difference score

Answer 13

The difference between an athlete’s score at the beginning and end of a training period or between any two testing times

Question 14

Effect size

Answer 14

The difference or change in the mean score as a proportion of the pretest standard deviation

Question 15

Flexibility

Answer 15

The range of motion (ROM) about a body joint

Question 16

High-speed muscular strength

Answer 16

The ability of muscle tissue to exert high force while contracting at high speed - also known as anaerobic power

Question 17

Local muscular endurance ​

Answer 17

The ability of certain muscles or muscle groups to perform repeated contractions against submaximal resistance

Question 18

Low-speed muscular strength

Answer 18

The maximum force a muscle or muscle group can exert in one maximal effort while maintaining proper form

Question 19

Magnitude statistics

Answer 19

Statistics that allow interpretation of the clinical significance of fitness testing such as the smallest worthwhile change and effect size

Question 20

Maximal anaerobic muscular power

Answer 20

The ability of muscle tissue to exert high force while contracting at high speed - also known as anaerobic power

Question 21

Mean

Answer 21

The average of the scores - the most commonly used measure of central tendency

Question 22

Median

Answer 22

The middlemost score when a set of scores is arranged in order of magnitude - half of the group falls above and half below the median score

Question 23

Mode

Answer 23

The score that occurs with the greatest frequency - requires at least two equal value scores - generally the least useful measure of central tendency

Question 24

Percent change

Answer 24

The relative percent increase or decrease in performance based on initial testing

Question 25

Percentile rank

Answer 25

The percentage of test-takers scoring below the individual being ranked

Question 26

Range

Answer 26

The interval of lowest to the highest score

Question 27

Smallest worthwhile change

Answer 27

The ability of a test to detect the smallest practically important change in performance

Question 28

Speed

Answer 28

Movement distance per unit of time

Question 29

Stability

Answer 29

A measure of the ability to return to the desired position following a disturbance to the system

Question 30

Standard deviation

Answer 30

A measure of the variability of scores around a mean - SD = √(Σ(x-▁x)²/(n-1))

Question 31

Statistics

Answer 31

The science of collecting, classifying, analyzing, and interpreting numerical data

Question 32

Variability

Answer 32

The degree of dispersion of scores within a group. Includes range and standard deviation
