The ability of heart and lungs to supply oxygen over time
What is cardiovascular endurance?
The ability to change direction quickly.
What is Agility?
Incorporates a detailed analysis of sport movements in order to minimise the risk of injury and improve sports performance.
What is biomechanics?
All parts of the body move the same distance, direction & time
What is linear motion?
Once forces are applied to a body, we can create motion.
What is momentum?
The maximum force a muscle can exert in one effort
What is muscular strength?
Keeping your body upright on one leg.
What is balance?
This is the push or pull applied to an object.
What is force?
Movement in a curved line (e.g., bottom of a ski jump).
What is curvilinear motion?
How long a force is applied for (F x time)
What is impulse?
Ability of muscles to perform repeated contractions.
What is muscular endurance?
The time it takes to start moving after a stimulus.
What is reaction time?
The individual forces that produce successive movements being added to create a larger total force.
What is force summation?
Movement of a body around a fixed axis (internal or external).
What is angular motion?
As long as no force is applied to speed it up or slow it down, its momentum is said to be conserved.
What is the law of conservation of momentum?
How easily a limb can be moved through its range of motions when executing a skill, for example, the arm action in backstroke, or the follow-through when kicking a ball.
What is dynamic stretching?
The ability to generate force quickly (e.g. vertical jump)
What is muscular power?
Occur when the system of bones, muscles, tendons and ligaments act on one another.
Internal force
A combination of linear and angular motions
What is general motion?
Mass x velocity
Determining one's ability to move a joint to its maximum range of motions.
What is static stretching?
Working at 60-80% max HR (Low intensity) (Jog, walk, swim, bike ride)
What is aerobic exercise?
Forces exerted from outside the body – by gravity or by contact with some other body part.
What are external forces?
Distance / time
What is the formula for speed?
Momentum is particularly important in _____ ______ because the result of the impact depends very largely on the momentum possessed by each of the bodies involved.
Why is momentum important in impact sports?
