HEALTH-RELATED COMPONENTS OF FITNESS• Cardiovascular

Fitness/Cardiorespiratory Endurance

• Muscular Strength and Endurance• Flexibility• Body Composition

04/19/23 EXERCISE AND FITNESS 12

Contributing Components of Fitness• Balance• Agility• Coordination• Power• Speed

04/19/23 EXERCISE AND FITNESS 13

CARDIORESPIRATORY ENDURANCECardiovascular Fitness• Pumps blood through body efficiently• Delivers O2 to cells• Removes wastes from cells• Derives energy from a process that

requires O2 from blood• Establishes training heart rate• Rebounds from stress more efficiently

04/19/23 EXERCISE AND FITNESS 14

FLEXIBILITY• Moves joints through full range of motion ROM• Varies from person to person and joint to joint• It has a genetic base• Genetics determine how elastic the muscles

and connective tissues will be• Differs from men due to skeletal difference

and muscle mass-women more flexible• Relieves or prevents pain from exercise• Prevents potential injuries

04/19/23 EXERCISE AND FITNESS 15

AEROBIC TRAINING/ Conditioning• Increases bodies ability to use O2 • Improves endurance• Lowers blood cholesterol, BP, • Enables lungs and heart to supply muscles

with O2• Achieved after 15-20 minutes of continuous

aerobic exercise• Uses large muscles of the legs and body for

repetitive movements over a sustained period of time

• Muscles• Organs• Bones• Teeth• Fat Tissue* added to LBW

04/19/23 EXERCISE AND FITNESS 36

BODY FAT PERCENTAGES• Essential body fat is @ 12-22%• Needed for healthy functioning of the

body• Non essential fat is 23% and up• This is stored as adipose tissue or excess

girth around organs• Energy for future needs• Measurement of one’s body fat provides a

better analysis of one’s body weight

04/19/23 EXERCISE AND FITNESS 44

BODY MASS INDEX

• If you weigh 140• Divide by 2.2• 140÷2.2 = 63.7(a)• This converts your

weight to kilograms

• If your height is 66 inches

• Divide by 39.4

• 66÷39.4 = 1.7 (b)• This converts your

height to meters• Square the answer• 1.7 X 1.7 = 2.89 (b2)• Divide weight in

kilograms by height in meters squared

• 63.7÷2.89 = 22.04
