components of fitness Flashcards
define areobic endurance
the ability of the cardiorespiration system to work efficiently supplying nutrients and oxygen to working muscles during sustained physical activity.
define muscular endurance
the ablity of the muscular system to work efficiently where a muscle can continue contracting over a period at a time against a light to moderate fixed resistance load.
flexibility
having an aduquate range of motion in all joints of the body; the ability to move a joint fluidly through its complete range of movement
speed
the distance 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 muscles, 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 more to change direction without loosing balance or time.
power
the product of strength and speed expressed as the work done in a unit of time.
re-action time
the time taken for a sports performer to respond to a stimulus and the initiation of their response.
what is aerobic endurance also known as…
cardiovascular endurance or cardio-respiratory fitness, this is because the cardio-respiratory system consists on the cardiovascular system.
list three types of speed
accelerate speed, pure speed and speed endurance.
list the two types of balance
static balance- gymnast holding a head stand
dynamic balance- gymnast performing a cartwheel.
define circuit training
a circuit can be adapted to allow an athlete to improve their strength muscular endurance and power
