| Question | Answer |
| Types of joint | Ball and socket- allows all range of movement. e.g Shoulder and hip joint Hinge Joint- Allows movement in one direction e.g. Knee and elbow joint |
| Planes | Sagittal- the verticle plane that divides the bidy into left and right halves Frontal- verticle plane that divides the body into back and front halves Transverse- divides the body into upper and lower halves |
| Axis | Transverse axis- Runs side to side of the body Sagittal axis- Runs front to back of thr body Longditudinal Axis- Runs top to bottom of the body |
| Joint actions in the sagittal plane about the transverse axis | - Hip flexion and extension -Hip hyper extension - elbow flexion and extension -Knee flexion and extension -Ankle Plantar flexion and extension -Shoulder flexion and extension |
| Joint Actions in frontal plane about sagittal axis | Abduction and adduction e.g. hips |
| Joint action at the transverse plane about the longitudinal axis | Horizontal abduction and adduction |
| Agonistic muscle | The muscle responsible for the movement that is occouring. (contracts and shortens) |
| Antagonistic Muscle | The muscle that works in the opposite direction to the Agonist muscle (Relaxes and lengthens) |
| Types of Muscular contraction- Isotonic contraction | A muscle causes movement in an isotonic contraction. Concentric- When the muscle shortens under tension e.g upwards phase of a bicep curl Eccentric-When the muscle lengthens under tension (and does not relax.) Acts as break in helping control parts of the movement. e.g. landing a standing jump |
