KINS 3545 EXAM 1 QUESTIONS AND ANSWERS | 2026 | GRADED A+ normal action movement - answer-insertion pulled toward a fixed origin ex. lying hamstring curl, lat pulldown, chest press reverse action movement - answer-origin pulled towards a fixed insertion ex. nordic curl, pull up, push up muscle roles - answer-agonist antagonist synergist/stabilizer/fixator/neutralizer muscle roles: agonist - answer-The active muscle(s) that drives the action / motion being performed. bicep curl - biceps leg extension - quads bench - pecs, anterior delts, triceps trap bar deadlift - quads (at knee), glutes (at hip) muscle roles: antagonist - answer-The passive muscles that would oppose the action if contracted bicep curl - triceps leg extension - hamstrings bench - lats, rhomboids trap bar deadlift - hip flexorsmuscle roles: synergist/stabilizer - answer-Includes all active muscles that indirectly assist the prime movers bench press- rotator cuff, legs (leg drive), fingers trap bar deadlift - hamstrings (they extend the hip (agonist) and flex the knee (antagonist)) can the (typically agonist) role of a muscle change during an exercise? - answer-no! agonist stays the same muscle throughout the whole exercise ex: bicep curl upward phase → biceps shorten to flex the elbow. downward phase → biceps lengthen under tension to control the descent. triceps aren't the agonist on way down, would cause arm to fling back uncontrolled. agonist = muscle that produces AND controls the motion. eccentric = same agonist, just resisting instead of creating movement how to ID if a muscle is active - answereccentric contraction importanct aspects - answer-Greater force capacity than concentric Lower neurological activity Lower metabolic demands More muscle damage/DOMS (24-72 hrs post-exercise).
