Chapter 2: Principles Of Physical Fitness Flashcards
Reversibility
The training principle that fitness improvements are lost when demands in the body are lowered
Exercise
Planned, structured, repetitive movement intended to improve or maintain physical fitness
Health related fitness
Physical capacities that contribute to health: cardiovascular endurance, muscle strength, flexibility, and body composition.
Cardiorespiratory endurance
The ability of the body to perform prolonged, large muscle, dynamic exercise at moderate to high levels of intensity.
Flexibility
The ability to move joints through their full range of motion.
Physical training
The performance of different types of activities that cause the body to adapt and improve its level of fitness
Fat- free mass
The nonfat component of the human body, consisting of skeletal muscle, bone and water.
Muscular endurance
The ability of a muscle to remain contracted or to contract repeatedly for a long period of time.
Metabolism
The sum of all the vital processes by which food energy and nutrients are made available to and used by the body
Intensity
Fitness benefits occur when a person exercise Shaffer than his/her normal level of activity
Progressive overload
The training principle that placing increasing amounts of stress on the body causes adaptions that improve fitness.
Specificity
The training principle that the body adapts to the particular type and amount of stress placed on it
Body composition
The proportion of fat and fat-free mass in the body
Physical activity
Body movement carried out by skeletal muscles that requires energy
Muscular strength
The amount of force a muscle can produce with a single maximum effort.
