| Question | Answer |
|---|---|
| What does anterior mean? | Towards the front |
| What does Posterior mean? | Towards the back |
| What does Superior mean? | Towards the head |
| What does Inferior mean? | Toward the feet |
| What does Medial mean? | Toward or at the midline of the body |
| What does Lateral mean? | Away from the midline of the body |
| What does Proximal mean? | Located nearer to a point of reference |
| What does Distal mean? | Located further from a point of reference |
| What does Flexion mean? | Away movement that decreases the angle of the joint |
| What does Extension mean? | Any movement that increase the angle of the joint |
| What does Abduction mean? | Movement of a limb away from the body |
| What does Adduction mean? | Movement of a limb towards the body |
| What does Rotation mean? | Movement of a bone around its longitude axis without lateral or medial displacement, such as shaking the head |
| What does Circumduction mean? | Combination of flexion, abduction, extension and adduction performed one after the other |
| What does Supination mean? | Movement so the radius and ulna at the elbow so that the palm is up |
| What does Pronation mean? | Movement so the radius and ulna at the elbow, so the palm is down |
| What does Inversion mean? | Movement of the sole of the foot inwards |
| What does Eversion mean? | Movement of the sole of the foot outwards |
| What is Kinematics? | Motion of a body |
| Three types of motion? | Linear motion, Angular motion, General motion |
| Define linear motion? | Motion of a body in a straight line |
| Define angular motion? | Motions of all parts of the object move around a fixed point. |
| Define general motion? | Combination of linear and angular. e.g. Swimming. |
| Which type of motion can be internal and external? | Angular motion, eg internal: Shoulder Joint, External: Eneven Bars |
| What is projectile motion? | Object which moves through the air |
| What are the factors affecting projectile motion? (6) | Velocity at release, Angle of release, Height of release, Shape, Air Resistance and Spin |
| Give an example of an object which would have a angle of release over 45 degrees and one below 45 degrees? | U: Bowl in cricket H: Netball shot |
| Briefly explain velocity at release? | The harder a ball is hit or thrown the higher and further it'll travel |
| Briefly explain angle of release? | Angle of release depends of the shape and aerodynamic properties of the projectile |
| Briefly explain height of release? | Higher the point of release relative to the ground the further the projectile will follow |
| Briefly explain what the shape has to do with projectile motion? | Streamlined shapes travel more effectively in the air due to less drag force |
| What is Air Resistance? | When a projectile pushes through the air it creates a drag force behind it |
| What is Kinetics? | Forces associated with motion |
| Define mass and what it is measured in? | Amount of matter that makes up an object, measured in KG |
| Define force? and what is it measured in? | Is the push or pull on a body that can possibly cause change, me |
| Two types of forces? | From within the body by muscular contractions, With an aid of equipment |
| Newtons first law of motion? | A body continues in it's state of rest or state of motion unless acted upon by a force |
| Force can achieve what? | Acceleration, Deceleration, Stop, Start, Change shape, Change Direction |
| Newtons second law of motion? | Force = mass x acceleration |
| Newtons third law of motion? | For every action there will be an equal and opposite reaction |
| What acts as leavers and what acts as axis? | Bones act as leavers while joints act as axis |
| Define Stability? | The body's ability to remain in a state of balance, stability can be static or dynamic. |
| Why do we analyse performance? (3) | Ensure the correct techniques are being used Identify Errors Justify the suggested changes in technique that are recommended |
| How many steps are there in biomechanical analysis? | 6 |
