Section A: Applied Anatomy and Physiology 8. Movement analysis of sporting actions associated with each joint Syllabus • Practical analysis of typical sporting actions associated with each joint, to include identification of joint, joint type, movement occurring, working muscles, functions of the muscles, type of contraction For more information see the word documents titled ‘Movement analysis table’ Basic analysis of movement can be done visually and should involve the following: • A description of the actual movements which occur at the joints involved • The plane(s) in which the movement occurs • The muscles producing the movement • The function of the muscles involved (agonists, antagonists, synergists & fixators) • The type of contraction (isotonic -concentric or eccentric, isometric) • The range of the muscle action (inner, middle, outer) Analysis of sprinting • The leg action in running is one that takes place in a sagittal plane about a frontal axis and involves the hip, knee and ankle joints. • The bones of the hip involved are the femur and pelvic girdle which form a ball and socket joint. The bones of the knee involved are the femur and tibia which form a hinge joint. The bones of the ankle involved are the tibia and calcaneus which form a modified joint. • Each of these joints produces two actions, one when the leg is in contact with the ground (driving phase) and one when the leg is not in contact with the ground (recovery phase). Driving phase Joints involved Hip Action Agonist Muscle Gluteal muscles (gluteus maximus and gluteus Extension and minimus) and Hamstrings (biceps femoris, hyperextension semimembranosus, semitendinosus) Knee Extension Ankle Plantar flexion Quadriceps group of muscles (rectus femoris, vastus medialis, vastus lateralis and vastus intermedialis) Gastrocnemius Recovery phase Joints involved Action Hip Flexion Iliopsoas Flexion Hamstrings (biceps femoris, semimembranosus, semitendinosus) Knee Ankle Agonist Muscle Dorsi flexion Tibialis anterior Analysis of throwing •Throwing comprises of two phases, the preparatory phase and the throwing phase. •Most actions are rotational in the transverse plane and longitudinal axis and the two joints primarily involved are the elbow and shoulder. •The elbow is a hinge joint formed by the humerus and ulna. •The shoulder is a ball and socket joint formed between the humerus and the scapula. Preparatory phase Joints involved Articulating bones Shoulder Elbow Humerus and scapula Action Agonist Muscle Horizontal Posterior deltoids and latissimus hyperextension dorsi Humerus and ulna Extension Triceps brachii Throwing phase Joints involved Articulating bones Action Humerus and Shoulder scapula Horizontal flexion Anterior deltoids and Pectoralis major Flexion Biceps brachii Elbow Humerus and ulna Agonist Muscle Analysis of racket strokes •There are two phases to striking a ball with a racket, the preparatory phase and the striking phase. •Most actions are rotational in the transverse plane and longitudinal axis and the three joints concerned are the wrist, elbow and the shoulder •The elbow is a hinge joint formed by the humerus and ulna. •The shoulder is a ball and socket joint formed between the humerus and the scapula •The wrist forms a condyloid joint between the ulna and carpal bones Preparatory phase Joints involved Articulating Action bones Ulna and carpal Wrist Supination Radius and ulna Humerus and Elbow Extension ulna Agonist Muscle Supinator Triceps brachii Humerus and Horizontal Posterior deltoid and Shoulder scapula hyperextension latissimus dorsi Striking phase Joints involved Articulating bones Action Agonist Muscle Wrist Ulna and carpal Pronation Radius and ulna Pronator teres Elbow Humerus and ulna Flexion Biceps brachii Shoulder Humerus and scapula Horizontal flexion Pectoralis major and Anterior deltoid Rotation External obliques Trunk Analysis of jumping •The action in jumping is one that takes place in a sagittal plane about a transverse axis and involves the hip, knee and ankle joints. •The bones of the hip involved are the femur and pelvic girdle which form a ball and socket joint. •The bones of the knee involved are the femur and tibia which form a hinge joint. •The bones of the ankle involved are the tibia and calcaneus which form a modified joint. Joints involved Hip> Knee Ankle Action Agonist Muscle Gluteal muscles (gluteus maximus and gluteus Extension and minimus) and Hamstrings (biceps femoris, hyperextension semimembranosus, semitendinosus) Extension Quadriceps group of muscles (rectus femoris, vastus medialis, vastus lateralis and vastus intermedialis) Plantar flexion Gastrocnemius Analysis of kicking •The action in kicking is one that takes place in a sagittal plane about a frontal axis and involves the hip, knee and ankle joints. •The bones of the hip involved are the femur and pelvic girdle which form a ball and socket joint. •The bones of the knee involved are the femur and tibia which form a hinge joint. •The bones of the ankle involved are the tibia and calcaneus which form a modified joint. •Kicking comprises of two phases, the preparatory phase and the kicking phase. Preparatory phase Joints involved Hip Knee Ankle Action Agonist Muscle Extension and Gluteal muscles (gluteus maximus and hyperextension gluteus minimus) Flexion Hamstrings (biceps femoris, semimembranosus, semitendinosus) Plantar flexion Gastrocnemius Kicking phase Joints involved Action Hip Flexion Knee Ankle Agonist Muscle Iliopsoas Quadriceps group of muscles (rectus Extension femoris, vastus medialis, vastus lateralis and vastus intermedialis) Plantar flexion Gastrocnemius
