components of fitness Flashcards
Aerobic endurance
The ability of the cardiorespiratory system to work efficiently, supplying nutrients and oxygen to working muscles during sustained physical activity
Muscular endurance
The ability of muscular system to work efficiently, where a muscle can continue, contracting over a period of time against a light to moderate fixed resistance load.
Flexibility
Having an adequate range of motion in all joints of the body; the ability to move a joint fluidly through its complete range of movement.
Speed
Distance is divided by the time taken. Speed is measured in metres per second (m/s). The faster an athlete runs over a given distance, the greater their speed.
Muscular strength
The maximum force (in kg or N) that can be generated by a muscle or muscle group.
Body composition
The relative ratio of fat mass to fat free mass (vital organs, muscle, bone) in the body
Co ordination
The smooth flow of movement needed to perform a motor task efficiently and accurately.
Balance
The ability to maintain centre of mass over a base of support.
Agility
The ability of a sports performer to quickly and precisely move or change direction without losing balance or time.
Power
The product of strength and speed expressed as the work done in a unit of time.
Reaction of time
The time taken for a sports performer to respond to a stimulus and the initation of their response.
Aerobic endurance also known as cardiovascular
The cardiorespiratory system consists on the cardiovascular system (heart, blood and blood vessels) together with respiratory system (lungs and airways).
Acclerative soeed
Sprints up to 30m
Pure speed
