ISSA Unit 4 Test Bank Solution Manual Already Passed Kinesiology - Answers Study of human movement dealing with muscles and muscles functions. list 3 types of muscular contractions - Answers •concentric muscles shorten to produce movement •eccentric muscles lengthens(stretches) as it contracts •isometric muscles exhibits strength but the limbs do not move concentric contraction - Answers •when the muscles contract it overcomes the resistance and the cause of the resistance is set into motion i.e: bicep curl •muscular force and movement are in the same direction eccentric contraction - Answers •aka yielding contraction •the more the muscle lengthens or the faster it stretches the greater the tension that is develop •important role for controlling and stopping movement •50 percent greater tension than concentric •muscular force is the opposite direction of the movement isometric contraction - Answers •the muscle develops tension and some shortening of the muscle fibers and tension occurs but limbs and body do not move •20 per cent greater strength than concentric •applied muscular force meets an equal resistance the result is no movement . explain the relationship between kinesiology and biomechanics - Answers •kinesiology explored the muscular involvement in strength exercise and sport-specific techniques, while biomechanics look at the physical factors involved in the movement Define prime mover - Answers •aka agonist •the main muscle involved in a concentric contraction (muscles shorten) •i.e biceps during bicep curls assistant mover - Answers •usually plays a secondary role to the prime mover muscles involed. •i.e the pronator teres is a prime mover in pronation and an assistant in elbow flexion antagonist - Answers something opposing or resisting the action of another •ungoes the eccentric contraction explain the relationship between agonist and antagonist - Answers •antagonist muscle has an action directly opposite that of the agonist •i.e the tricep is antagonist to the biceps. Stabilizer muscles - Answers •is a muscle that holds a body part in place i.e knee extension , over head press explain synergy as it relates to muscles - Answers •helping synergy: when two muscles contract simultanelously to produce one movement while their other actions cancel each other out i.e set-ups , external obliques during a crunch •true synergy: a different muscle contracts to stop the secondary action of another i.e biceps brachii list the four types of muscular movement - Answers •ballistic •guided •dynamic balance •sustained ballistic - Answers •movement in which inertial movement exists after an explosive or quick maximum force contraction guided - Answers •movement that occurs when both the agonist and the antagonist contract to control the movement i.e writing dynamic balance - Answers •movement in which constant agonist-antagonist muscle contractions occur in order to maintain a certain position or posture. i.e balancing on one leg sustained - Answers •movement in which continuous muscle contractions occur in order to keep moving a weight i.e slow lifting of heavy weights usually invoked co contraction of antagonist. co-contraction - Answers •when both the agonist and the antagonist undergo contraction define the three imaginary planes of motion. - Answers •transverse •frontal •sagittal transverse - Answers •horizontal • separates the body into superior(top) and inferior(bottom) sections. •standing med ball twist •torso twist with bands •wipers frontal - Answers •coronal •separates the body into anterior(front) and posterior(back) parts •lateral dumbbell raise •side lunges •jumping jacks sagittal - Answers •anteroposterior •separates the body into right and left sections •dead lift
