physical activity

body movement carried out by the skeletal muscles that requires energy


planned, structured, repetitive movement intended to improve or maintain physical fitness

health-related fitness

physical capacities that contribute to health: cardiorespiratory endurance, muscular strength, muscular endurance, flexibilty, and body compostion

cardiorespiratory endurance

the ability of the body to perform prolonged, large-muscle, dynamic exercise at moderate to high levels of intensity

muscular strength

the amount of force a muscle can produce with a single maximum effort


the sum of all the vital processes by which food , energy and nutrients are made available to the body

muscular endurance

the ability of a muscle to remain contracted or to contract repeatedly for a long period of time


the ability to move joints through their full range of motion; many factors such joint structure affect; needed in everyday routines

body composition

the proportion of fat and fat-free mass (muscle, bone, and water) in the body

fat-free mass

the nonfat component of the human body, consisting of skeletal muscle, bone, and water

skill-related fitness

physical capabilities that contribute to performance in a sport or an activity: speed, power, agility, balance, coordination, and reaction time

physical training

the performance of different types of activities that cause the body to adapt and improve its level of fitness


the training principle that the body adapts to the particular type and amount of stress placed on it

progressive overload

the training principle that placing increasing amounts of stress on the body causes adaptations that improve fitness; too little exercise--will have no effect on fitness too much--may cause injury


the training principle that fitness improvements are lost when demands on the body are lowered

exercise stress test

a test usually administered on a treadmill or cycle ergometer that involves analysis of the changes in electrical activity in the heart from an electrocardiogram (EKG, ECG) taken during exercise; used to determine if any heart disease is present and to assess current fitness level

graded exercise test (GXT)

an exercise test that starts at an easy intensity and progresses to maximum capacity


a condition caused by training too much or too intensely; characterized by lack of energy, decreased physical performance, and aching muscles and joints


___% of adults participate in some leisure-time physical activity
