Physical Activity
Refers to all body movements produced by skeletal movements produced by skeletal muscles, resulting in substantial increases in energy expenditure
Exercise

Sedentary
Activity that expends no more than 1.5 times the resting energy level while seated or reclined
MET
A metabolic equivalent or resting level of energy expenditure (3.5 ml · kg^-1 · min^-1)
Physical Fitness
A balance of health-related attributes that allows you to perform moderate to vigorous physical activities on a regular basis and complete daily physical tasks without undue fatigue
Cardiorespiratory Fitness
The ability of the heart, lungs, and blood vessels to supply oxygen to skeletal muscles during sustained physical activity
Aerobic Exercise
Prolonged exercise that requires oxygen to make energy for activity
Aerobic Capacity (Power)
The functional status of the cardiorespiratory system; refers specifically to the volume of oxygen the muscles consume during exercise
Muscular Strength
The amount of force that a muscle is capable of exerting in one contraction
Muscular Endurance
A muscle’s ability to exert force repeatedly without fatiguing or the ability to sustain a muscular contraction for a length of time
Flexibility
The range of motion, or the amount of movement possible, at a particular joint or series of joints
Body Composition
The relative proportions of fat and fat-free (muscle, bone, water, organs) tissues in the body
FITT
Acronym for frequency, intensity, time, type; the terms that describe the essential components of a program or plan to improve a health-related component of physical fitness
