- CORRECT ANSWER Outside shin What is the location of the erector spinae? - CORRECT ANSWER Centre of back What is the location of the teres major? - CORRECT ANSWER Between scapula and humerus What is the location of the latissimus dorsi? - CORRECT ANSWER Centre at side back What is the location of the obliques? - CORRECT ANSWER Side of torso What is the location of the gluteals? - CORRECT ANSWER Bum What is the function of the triceps? - CORRECT ANSWER Extension of forearm at elbow joint What is the function of the deltoids? - CORRECT ANSWER Stability of shoulder joint and upper arm What is the function of the pectorals? - CORRECT ANSWER flexion, adduction, and internal rotation of the humerus What is the function of the biceps? - CORRECT ANSWER Flexion of elbow and supination of forearm What is the function of the wrist flexors? - CORRECT ANSWER Flexion and abduction of wrist What is the function of the wrist extensors? - CORRECT ANSWER Extends hand at wrist What is the function of the supinators? - CORRECT ANSWER Rotates radius laterally at proximal radioulna joint What is the function of the pronators? - CORRECT ANSWER Exclusive upper limb movement What is the function of the abdominals? - CORRECT ANSWER Allow movement and hold organs in place What is the function of the hip flexors? - CORRECT ANSWER Allow you to move lower body What is the function of the quadriceps? - CORRECT ANSWER Extend leg at knee joint and flex thigh at hip joint What is the function of the hamstrings? - CORRECT ANSWER Allows thigh to extend, tibia to rotate and hip to flex What is the function of the gastrocnemius? - CORRECT ANSWER Plantar flexor of foot and flexes leg at knee What is the function of the soleus? - CORRECT ANSWER Plantar flexion of upper ankle joint enabling lifting of heel What is the function of the erector spinae? - CORRECT ANSWER Move the vertebral column What is the function of the teres major? - CORRECT ANSWER Produce movements of humerus at the glenohumeral joint What is the function of the trapezius? - CORRECT ANSWER Stabilise and move scapula What is the function of the latissimus dorsi? - CORRECT ANSWER Pull inferior angle of scapula in various directions What is the function of the obliques? - CORRECT ANSWER Pull chest downwards and compress abdominal cavity What is the function of the gluteals? - CORRECT ANSWER Extension and external rotation of thigh at hip joint Where do muscles cross and why? - CORRECT ANSWER Cross the joints to allow them to move What do bones act as? - CORRECT ANSWER levers What do joints act as? - CORRECT ANSWER fulcrums What does the strength of muscle contraction depend on? - CORRECT ANSWER Number of muscle fibres needed to be used What do muscles need to contract? - CORRECT ANSWER Oxygen and fuel source (fat or glucose) What do muscles convert chemical energy into? - CORRECT ANSWER Mechanical energy What is the agonist muscle? - CORRECT ANSWER also called prime mover, muscle whose contraction is chiefly responsible for producing a particular movement example: biceps brachii for elbow flexion What is the antagonist muscle? - CORRECT ANSWER Muscle that relaxes during contractions, opposite of agonist, if it doesn't relax no movement can take place What is a synergist muscle? - CORRECT ANSWER Work with agonist to control and direct movement by modifying or altering direction of pull on agonist What is a fixator muscle? - CORRECT ANSWER Stop unwanted movement by fixing or stabilising joints involved in movement What is the antagonist to the bicep? - CORRECT ANSWER Tricep What is the antagonist to the deltoid? - CORRECT ANSWER latissimus dorsi What is the antagonist to the pectoralis major? - CORRECT ANSWER Trapezius What is the antagonist to the rectus abdominus? - CORRECT ANSWER Erector spinae What is the antagonist to the iliopsoas? - CORRECT ANSWER Gluteus maximus What is the antagonist to the quadriceps? - CORRECT ANSWER Hamstrings What is the antagonist to the hip adductor? - CORRECT ANSWER Gluteus medius What is the antagonist to the tibialis anterior? - CORRECT ANSWER Gastrocnemius What are the 3 main types of muscle contraction? - CORRECT ANSWER Concentric, eccentric and isometric What is a concentric contraction? - CORRECT ANSWER muscle shortens, positive phase of muscle contraction What is eccentric contraction? - CORRECT ANSWER muscle lengthens, negative phase of muscle contraction What is isometric contraction? - CORRECT ANSWER Length of muscle doesn't change, joint angle doesn't change, quickly leads to fatigue How to find max heart rate? - CORRECT ANSWER 220-age= Ways of finding your heart rate? - CORRECT ANSWER Radial (wrist) Carotid (neck) How to find your training zone? - CORRECT ANSWER 60-80% of max heart rate What component of fitness does your training zone mainly improve? - CORRECT ANSWER Cardiovascular endurance Health components of fitness? - CORRECT ANSWER Cardiovascular Endurance Muscular Endurance Strength Flexibility Body Composition Skill components of fitness? - CORRECT ANSWER Agility Balance Co-ordination Power Reaction time Speed
