Term 3 Refining Skills using Biomechanics Flashcards
What are biomechanics?
Biomechanics is an area of sports science that applies the laws of physics and mechanics to improve performance in sport.
Force Production & Application
All movement skills including running, jumping, throwing, kicking and striking, require the application of muscular force.
What are some important factors in force production and application?
-Force summation
-Impulse
-Absorption of force
-Accuracy
What is force summation?
Force Summation refers to the correct timing and sequencing of the parts of your body and muscles through a range of motion.
What are the two ways that summation of force can occur?
Sequential summation of force
Simultaneous summation of force
What is sequential summation of force?
Sequential summation of force is when a sequence of body movements takes place, starting with the larger, more powerful body parts to produce the initial force, and then transferring this force to the next moving part and eventually finishing with the smaller, lighter body parts.
What is simultaneous summation of force?
Simultaneous summation of force is when the performer carries out an explosive action with maximum force over a very short period of time.
What is impulse?
Impulse refers to the force applied to an object and the length of time the force is applied as well as the change in momentum during a movement, by applying a force for a longer period of time.
What is force absorption?
Absorbing the force means that the object that is in motion is slowed or stopped.
The longer the force is absorbed, the easier it is to slow down.
What is Projectile Motion?
Projectile Motion refers to the motion of objects that are thrown, struck or kicked into the air.
What is Velocity of Release?
Velocity of Release (speed of release) is the single most important factor for achieving maximum distance of a Projectile.
What is Angle of Release?
Angle of Release refers to the angle at which a projectile is released.
What is stability?
Stability refers to an object’s resistance to movement from a balanced position.
What is Base of Support ?
Base of Support refers to part or parts of the object in contact with the support surface.
What is Centre of Gravity?
Centre of Gravity refers to the point in any object or body through which the downward force of gravity acts.
