Chapter 2 - Principles of Fitness - Terms & Definitions Flashcards
Physical Activity
Any body movement carried out by the skeletal muscles and requiring energy.
Exercise
Planned, structured, repetitive movement of the body designed to improves or maintain physical fitness.
Health-related fitness
Physical capacities that contribute to health: cardiorespiratory endurance, muscular strength, muscular endurance, 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
Muscular Strength
the amount of force a muscle can produce with a single maximum effort
metabolism
the sum of all the vital processes by which food energy and nutrients are made available to and used by the body
Muscular Endurance
the ability of a muscle or group of muscles to remain contracted or to contract repeatedly for a long period of time
Flexibility
the range of motion in a joint or group of joints, flexibility is related to muscle length
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 capacities that contribute to performance in a sport or 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
specificity
the training principle that the body adapts to the particular type and amount of stress placed on it
progressive overload
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 te heart from an electrocardiogram (EKG or ECG) taken during exercise. Used to determine if any heart disease is present and to assess current fitness level.
