Physical Activity
Movement carried out by the skeletal muscles requiring energy, which can vary in ease or intensity.
Exercise
A planned, structured, repetitive movement explicitly intended to improve or maintain physical fitness.
Physical Fitness
A set of physical attributes that allows the body to respond or adapt to the demands and stress of physical effort.
Cardiorespiratory Endurance
The ability to perform prolonged, large-muscle dynamic exercise at moderate-to-high intensity levels.
Muscular Strength
The ability of a muscle to exert force in a single maximum effort.
Muscular Endurance
The ability of a muscle to resist fatigue and sustain muscle tension over time.
Flexibility
The ability to move joints through their full range of motion.
Body Composition
The proportion of fat and fat-free mass (muscle, bone, and water) in the body.
FITT Principle
A guideline for creating an exercise program based on Frequency, Intensity, Time, and Type.
Progressive Overload
The training principle that progressively increasing amounts of stress on the body causes adaptation that improves fitness.
Reversibility
The principle that fitness improvements are lost when demands on the body are lowered.
Specificity
The training principle that developing a particular fitness component requires performing exercises specifically designed for that component.
Sedentary
A lifestyle characterized by a lack of physical activity.
Moderate-intensity Exercise
Activities that increase your heart rate and breathing but still allow for comfortable conversation.
Vigorous-intensity Exercise
Physical activities that cause rapid breathing and a substantial increase in heart rate.
Lifestyle Physical Activity
Physical activities incorporated into daily routines that contribute to overall health.
