Exam 1 (Ch 1-4) HSC101 - Definitions


a state of complete well-being, including the absence of disease

Life Expectancy

the number of years a person can expect to live

Healthy life expectancy

number of years a person is expected to live in good health

What is the U.S. ranked in life expectancy?


What country has the longest life expectancy?

Japan - 81.0

Leading causes of death in the US

heart disease, cancer, chronic lower respiratory disease

For all populations, 25% deaths can be attributed to four things:

Tobbaco use, Poor Diet, Inactivity, Alcohol Abuse

Cardiovascular disease

group of diseases that affect the heart or blood vessels which includes coronary artery disease, heart attack, heart failure, stroke, and peripheral vascular disease

coronary heart disease

clogging of arteries in the heart with fat deposits

heart attack

death of heart tissue from oxygen depravation due to blood clot or vessel spasm is clogged artery

Heart failure

weakening of the heart muscle over time due to factors such as high blood pressure


brain tissue death from oxygen depravation resulting from a blood clot in a brain blood vessel

Peripheral Vascular disease

clogging of arteries in other parts of the body besides the heart with fat deposits

Sudden Death

1/5 of CV deaths are sudden deaths


uncontrolled growth and spread of abnormal cells in the body

Dimensions of wellness

physical, emotional, intellectual, interpersonal, cultural, spiritual, environmental, financial, occupational

Mazlow's Hierarchy of Needs

self-actualization, esteem, love/belonging, safety, physiological

Self actualization

the need for fulfillment, for realizing one's own potential, for using totally one's talents and capabilities

Physical fitness

The ability to meet the ordinary as well as the unusual demands of daily life safely and effectively without being overly fatigued and still have energy left for leisure and recreational activities

Health related physical fitness

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

motor skill physical fitness

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

What is exercise?

A type of physical activity consisting of planned, structured, and repetitive bodily movement done to improve and/or maintain one or more components of physical fitness

Moderate v. Vigorous

calories are different per exercise and times are different

Cardiorespiratory endurance

the 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


four muscular chambers that, when activated by an electrical signal, beat with precise timing to create pressure and push the blood forward


Microscopic vessel through which exchanges take place between the blood and cells of the body

endothelial cells

cells lining the blood vessels that help to control blood flow

Stroke Volume

the amount of blood ejected by the heart in each beat and is measured in liters/beat

Heart Rate

the total number of heart beats per minute

Cardiac output

the total amount of blood that the heart circulates in a minute and is measured in liters/minute


the heart builds up pressure and pushes blood toward the aorta


the heart relaxes, and as pressure falls, the heart chambers fill with blood again


fast acting, run out the quickest


not as fast as the immediate system but lasts longer. Oxygen not required

Aerobic oxidation

slowest, but longest lasting. Oxygen required

VO2 max

the maximum amount of oxygen that the body can consume in one minute


uses oxygen to produce energy


total amount work done in a period of time


the change in intensity, duration, or frequency as the body plateaus in its improvement

motor units

muscle fibers are activated in groups of 5-2000, depending on the muscle

Muscular strength

the ability to produce near maximum force in one or very few efforts

Muscular endurance

the ability to produce and maintain moderate force over the course of many efforts


increased muscle mass where individual muscle fibers increase in size


decrease in muscle size

Volitional fatigue

The point in a set where you cannot lift the next rep without cheating it up.


no movement


using explosive movements with light weights or body weight
