1

cardiorespiratory endurance

CR - Ability of the lungs, heart and blood vessels to deliver adequate amounts of oxygen to the cells to meet the demands of prolonged physical activity

1

Most important component of health related physical fitness

Cardiorespiratory endurance

2

hypokinetic disease

chronic ailments that results from a lack of physical activity

3

alveoli

air sacs in the lungs where oxygen is taken up and carbon dioxide (produced in the body) is released from the lungs

4

hemoglobin

protein - iron compound in red blood cells that transports oxygen in the blood

5

adenosine triphosphate

ATP - high energy chemical compound that the body uses for immediate energy

6

oxygen uptake

VO2 - amount of oxygen the human body uses
Bring in and utilize

7

aerobic

exercise that requires oxygen to produce the necessary energy (ATP) to carry out the activity
Over 2 minutes

8

anaerobic

exercise that does not require oxygen to produce the necessary energy (ATP) to carry out the activity
Under 2 minutes

9

maximum oxygen uptake

VO2max - maximum amount of oxygen the body is able to utilize per minute of physical activity, commonly expressed in milliliters per kilogram per minute

10

best indicator of CR or aerobic fitness

VO2max

11

resting heart rate

heart rate of a person who has been sitting quietly for 15-20 minutes

12

cardiac output

amount of blood pumped by heart in one minute

13

stroke volume

amount of blood pumped by heart in one beat

14

workload

load or intensity placed on the body during physical activity

15

mitochondria

structures within the cells where energy transformation takes place

16

capillaries

smallest blood vessels carrying oxygenated blood to the tissues in the body

17

recovery time

amount of time that the body takes to return to resting levels after exercise

18

benefits of cardiovascular (aerobic) fitness

first 6 text

- higher maximal VO2max
-increase in oxygen-carrying capacity of blood
-decrease in resting heart rate
-lower heart rate at given workloads
-increase in number, size and capacity of mitochondria
-increase in number of functional capillaries

19

benefits of cardiovascular (aerobic) fitness

next 3 text

-Ability to recover rapidly
-lower blood pressure and lipids
-increase in fat burning enzymes

20

benefits of cardiovascular (aerobic) fitness

others from diagram

-better health and quality of life
-improved brain function
-higher academic performance
-lower risk of stroke and depression
-lower risk of heart disease
-lower blood pressure
-improved balance and decreased risk of falls
-decreased pain from disability and arthritis
-decreased risk for osteoporosis and fractures
-lower risk of type 2 diabetes
-improved functional capacity
-decreased risk for several types of cancer

21

Purposes of physical fitness assessment

- educate participants on current level of fitness and compare to standard
-motivate individuals to participate
-provide starting point for exercise prescription and goals
-evaluate improvements
-monitor changes over years

22

responders

individuals who exhibit improvements in fitness as a result of exercise training

23

nonresponders

individuals who exhibit small or no improvements in fitness as a result of exercise training

24

principle of individuality

training concept holding that genetics plays a major role in individual responses to exercise training and these differences must be considered when designing exercise programs for different people

25

physical activity

bodily movements produced by skeletal muscles, which require the expenditure of energy and produces progressive health benefits.

26

exercise

type of physical activity that requires planned, structured, and repetitive bodily movement with the intent of improving or maintaining one or more components of fitness

27

maximal heart rate

highest heart rate for a person, related primarily to age

28

arterial-venous oxygen difference

a-vO2diff - amount of oxygen removed from the blood as determined by the difference in oxygen content between arterial and venous blood

29

5 exercise tests used to assess CR fitness

1.5 mile run test
1.0 mile walk test
step test
Astrand-Ryhming test
12 minute swim test
