Paper 1 Flashcards
Abduction
Movement away from mid-line of body
e.g. backhand shot in tennis
Adduction
Movement towards mid-line of body
e.g. forehand shot in tennis
Circumduction
Circular movement around the joint
Flexion
Angle of joint is decreasing
Eg bicep curl
Extension
Angle of joint is increasing
Eg throwing a ball
Rotation
Turning around an axis/fixed point
Hinge joints
Allow body parts to move forward and back (not side to side) + straightening and bending
Ball and socket joints
Allows backward, forward, sideways, and rotating movements
Hinge joint
Knee, ankle and elbow
Flexion and extension can occur here.
Ball and socket joint
Shoulder and hip
Abduction, adduction and rotation can take place
Dorsiflexion
Angle of joint decreasing at ankle
Plantarflexion
Angle of joint increasing at ankle
Cranium
Flat bone that protects the skull
Tendons
Attach muscle to bone
Ligament
Attaches a bone to a bone
Synovial membrane
Produces synovial fluid
Synovial fluid
Provides lubrication at a joint
Bursae
Sacks of fluid at a joint that reduce friction
Cartilage
Prevents friction/bones rubbing together, acts as a shock absorber to allow easier movement
Joint capsule
Encloses/ supports the joint
Concentric Contraction
When the muscle contracts and shortens e.g.when bending the elbow the biceps is the agonist
Isometric Contraction
When the muscle contracts but stays the same length e.g. tug of war, planking
Eccentric Contraction
When the muscle lengthens (relaxes) e.g. when bending the elbow, the antagonist is the tricep which lengthens
Antagonist
The muscle that relaxes to allow the movement to take place e.g. triceps during a dumbbell curl.
Shape
Function of the skeleton that provides the body with structure. Short bones enable fine movement an long bones enable gross movements.
Protection
Function of the skeleton, flat bones protect the body e.g. cranium protects the brain.
Support
Function of the skeleton where muscles and bones are kept in place supported by the skeleton.
Mineral storage
Function of the skeleton where the mineral calcium helps with bone formation.
Movement
Function of the skeleton where different types of joints allow different types of movement, muscles and bones work together to pull.
Talus
Found at the ankle
Scapula
Shoulder blade
Humerus
Long bone found in the arm
Fibula and tibia
Long bones found in the lower leg
Radius and ulna
Long bones found in the lower arm
Rib cage
Flat bone that protects vital organs such as the lungs, heart
Vertebrae
Protects spinal cord
Patella
Knee cap
Pelvis
Flat bone at the hips
Sternum
Flat Bone also known as the chest bones
Biceps and triceps
Biceps are found on the front of the arm, triceps are found at the back of the arm. Used in movements such as throwing.
Hamstrings and Quadriceps
Hamstrings are found at the top back of the leg, quadriceps are found at the front of the thigh. Used in running and kicking.
Gastrocnemius
Also know as the calf muscle found at the back of the lower leg. Involved with movements at the ankle.
Tibialis Anterior
Found at the shin at the front of the lower leg
Gluteals and Hip Flexors
Gluteals found at the bum, flexors found at the hips.
Latissimus Dorsi
Allows shoulder movement backwards, forwards, up and down. Found on the back.
Abdominals
Used to bend the trunk, important for core strength
Pectorals
At the front of the upper chest, used in throwing actions such as the javelin.
What does SPORT stand for .
Specificity, Progressive Overload, Reversibility, Tedium
What does FITT stand for?
Frequency, Intensity, Time, Type
Frequency
How often you train
Intensity
How hard you train
Time
How long you train for
Type
Which type of training you use
Reversibility principle
The benefits of exercise and training are lost if injury or inactivity occur
