1

fitness includes what 6 things?

1) Cardiorespiratory endurance
2) Flexibility
3) body composition
4) muscular strength
5) muscular power
6) muscular endurance

2

define physical fitness

the ability of the body to adjust to the demands and stresses of physical effort

3

what is physical fitness thought to be a measure of?

physical fitness is thought to me a measure of ones physical health

4

define physical activity

any movement carried out by the skeletal muscles

5

physical activity requires the use of ______

energy

6

muscle strength

the ability of a muscle or muscle group to exert force against a resistance

7

true or false: muscular strength is commonly measured as a maximal value

true

8

what is a synonym for strength?

force

9

greater muscle mass results in?

greater muscle mass results in greater strength

10

force = ____ x _____

force = mass x acceleration

11

power

the ability to overcome external resistance at a high rate of muscular contraction

12

what is the ability to exert fore dependent on?

muscular strength

13

_______ is a derivative of muscular strength

Power

14

muscular endurance

the ability of a muscle or muscle group to sustain a given level of force (static, exercise) or to repeatedly contract and relax (dynamic exercise) at a given resistance

15

what is an example of static exercise?

the flexed arm hang is an example of a static exercise

16

what is an example of a dynamic exercise?

sit-ups are an example of a dynamic exercise

17

agonist

working muscles

18

antagonist

counter-acting muscles

19

training should include exercises that stimulate both the ______ and the ______

agonists and antagonists

20

what 2 things happen when you focus only on increasing agonist strength?

1) tends to shorten the agonist muscles
2) tends to weaken the antagonist muscles

21

cardiorespiratory endurance

the ability to produce energy through an improved delivery of oxygen to working muscles

22

what 2 systems does cardiorespiratory endurance involve?

involves cardiovascular system and respiratory system

23

what is the major function of the cardiorespiratory system?

to provide oxygen to tissues

24

what is the cardiorespiratory system needed for?

exertion over longer periods of time

25

aerobic power

the maximal rate at which the body can take up, transport, and utilize oxygen

26

what is the maximal rate at which the body can take up, transport, and utilize oxygen expressed as?

maximal oxygen uptake or max VO2

27

what is max VO2 measured as?

max VO2 is measured as the maximal volume of oxygen consumption recorded during a progressive exercise test to exhaustion

28

predictions based on the _____ relationship between heart rate and workload can be made over a given workload range

linear

29

with increasing workload, ________ increases to a maximum that corresponds to a maximal oxygen consumption (max VO2)

heart rate

30

flexibility

the ability of a joint to move through its full range of motion
