Health Chap 3-8

Front 1

What is physical activity?

Back 1

Bodily movement that is produced by the contraction of skeletal muscle and that is substantially increases energy expenditure.

Front 2

What is the definition of exercise?

Back 2

A planned, structured, and repetitive bodily movement done to improve or maintain one or more components of physical fitness.

Front 3

What does performance related fitness consist of?

Back 3

Speed, power, balance, coordination, agility, and reaction time

Front 4

What is speed?

Back 4

velocity, the ability to move rapidly

Front 5

what is power?

Back 5

the product of force and velocity and the rate at which work is performed.

Front 6

what is balance?

Back 6

equilibrium, the ability to maintain a desired body position either statically or dynamically.

Front 7

what is coordination?

Back 7

is the harmonious integration of the body parts to produce smooth, fluid motion.

Front 8

what is agility?

Back 8

the ability to change direction rapidly.

Front 9

what is reaction time?

Back 9

the time required to respond to a stimulus.

Front 10

what measurement is used for determining reaction time?

Back 10

hundredths of a second

Front 11

what are the components of health-related fitness?

Back 11

cardiorespiratory endurance, muscular strength, muscular endurance, flexibility and body composition

Front 12

Racquetball, handball, squash, tennis, badminton, soccer, softball, basketball, football, water polo are examples of what?

Back 12

performance related

Front 13

what is cardiorespiratory endurance?

Back 13

the ability to take in, deliver, and extract oxygen for physical work, its the ability to persevere at a physical task at a given intensity level.

Front 14

what are some advantages of cardiorespiratory endurance?

Back 14

improves with regular participation in aerobic activities, such as speed walking, jogging, cycling, swimming, and cross country skiing.

Front 15

aerobic means what?

Back 15

with oxygen

Front 16

the term aerobic when applied to exercise refers to what?

Back 16

activities in which oxygen demand can be met continuously during performance

Front 17

what two things are burned during an aerobic performance?

Back 17

carbohydrates and fats

Front 18

what does the term steady state mean?

Back 18

a steady rate of oxygen flow as well as the ability to sustain the intensity or the energy requirement for longer then a few minutes.

Front 19

which exercise might someone be in a steady state?

Back 19

aerobic exercise

Front 20

describe the pay as you go system?

Back 20

the body will only use the amount of oxygen needed for the exercise, and if the flow of oxygen increases then the oxygen level will increase.

Front 21

what is aerobic capacity?

Back 21

the maximum oxygen consumption

Front 22

what is the most important component of physical fitness and the foundation of total fitness?

Back 22

aerobic capacity

Front 23

long term or chronic effects of exercise is what?

Back 23

physiological changes that result from cardiorespiratory training

Front 24

what is the length if time on average that steady oxygen consumption can be maintained for?

Back 24

10 to 60 minutes

Front 25

how many beats per minute can aerobic training lower the heart rate

Back 25

10 to 15 beats per minute

Front 26

what is the stroke volume?

Back 26

the amount of blood that the heart can eject in one beat

Front 27

aerobic training increases the stroke volume in what two ways?

Back 27

1. increases the size of the cavity of ventricles, which results in more blood filling the heart
2. increases the contractile strength of the ventricular wall, so contraction is more forceful and a greater amount of blood is ejected from the ventricles

Front 28

what is cardiac output?

Back 28

the amount of blood ejected by the heart in 1 minute

Front 29

what is the equation for cardiac output?

Back 29

cardiac output= heart rate x stroke volume

Front 30

cardiac output increases during aerobic training but does not do what?

Back 30

increase at rest or during submaximal exercise.

Front 31

why doesn't cardiac output change during rest or submaximal exercise?

Back 31

the lowered resting heart rate compensates for the increase in stroke volume

Front 32

the average cardiac output at rest is how many liters of blood per minute.

Back 32

4 to 6

Front 33

during maximal exertion, cardiac output reaches values of how many liters of blood per minute for an average person.

Back 33

18 to 20

Front 34

for an athlete during maximal exertion cardiac output can reach up to how many liters per minute.

Back 34

40

Front 35

maximum heart rate declines how many beats per minute starting at what age?

Back 35

1 bpm starting at age 20
