Human kinetics

Movement Analysis Table: Chin-up with hands supinated (going up and then down, under control) List the following movement: type, plane, axis, type of contraction (concentric, eccentric, isometric), and the muscles involved for the following movement at the shoulder, elbow, and hands. Movement Type (i.e. flexion extension etc.) Movement Plane (sagitt (antero-posterior (concentric, eccentric, frontal, transverse) Muscles Involved Movement Axes Type of Contraction isometric) medio-lateral, superior-inferior) Shoulders: pulling up phase (ascending) Elbows: pulling up phase (ascending) Hands: (gripping/clenching the bar during the entire movement Shoulders: down Elbows: down phase (descending)

Explanation / Answer

1)shoulders : pulling up phase( ascending):a)movement type: extension, b)movement phase:sagital, c) movement axis:mediolateral,d) type of contraction: concentric contraction, e)muscles involved: lattissimus dorsi, teres major, posterior deltoid, pectoralis major, long head of the triceps brachii. 2)elbows :pulling up phase(ascending ):a) movement type : flexion, b) movement phase: frontal c) movement axis:mediolateral, ,d)type of contraction: concentric contraction,e) muscles involved:Biceps brachii, Brachialis, Brachioradialis. 3)Hands(gripping /, clenching the bar during the entire movement:a) movement type: flexion, b)movement phase:frontal,c)movement axis:anterior posterior, d) type of contraction:isometric contraction, e) muscles involved: wrist flexors, hand flexors. 4)shoulders down phase(descending):movement type: extension, b)movement phase : sagittal: c) movement axis: mediolateral, d)type of contraction:eccentric,e)muscles involved:adductors: pectoralis major, posterior deltoid, latissimus dorsi, teres major, and subscapularis. 5)elbow down phase(descending):a) movement type: extension,b)movement phase:frontal, c)movement axis:anterior posterior, d)type of contraction: eccenttric, e) muscles involoved:elbow flexors, biceps brachii, brachialis, and brachioradialis.
