AAMC FL3 BB Exam 2024

AAMC FL3 BB Exam 2024 Individual M has longer limbs and muscles than Individual N. Both individuals lift the same amount of weight from the ground to their shoulders an equal number of times. If all repetitions were completed in synchrony, which statement about the amount of work completed by the individuals is true? At the end of the workout: A.both individuals will have done the same amount of work because the force was applied for the same duration of time. B.Individual M will have done less work because the object was moved a greater distance. C.Individual N will have done less work because the object was moved a shorter distance. D.Individual M will have done more work because the muscle contracted faster to achieve synchrony with Individual N. passage: The length of a muscle fiber does not contribute to the force it generates. Length, however, is important in determining how much work the muscle can do. Assuming two muscles hav -Answer-C.Individual N will have done less work because the object was moved a shorter distance. this is stated in the passage. Answer choice D is wrong because work is not dependent on speed. work= force x distance What are the relative potentials for force and power generation by a slow-twitch muscle fiber and a fast-twitch muscle fiber of the same diameter? A.The slow-twitch and fast-twitch fibers possess the same potentials for force and power generation. B.The slow-twitch fiber is capable of generating more force than the fast-twitch fiber, while the potential for power generation is the same. C.The fast-twitch fiber is capable of generating more power than the slow-twitch fiber, while the potential for force generation is the same. D.The fast-twitch fiber is capable of generating more force than the slow-twitch fiber, while the potential for power generation is the same. passage: certain types of exercise can increase fiber diameter (hypertrophy). This effect is largely limited to fast-twitch fibers. When these fibers are stimulated by anaerobic exercise such as weight lifting or sprinting, the size of myofibrils is i -Answer-C.The fast-twitch fiber is capable of generating more power than the slow-twitch fiber, while the potential for force generation is the same. this is literally given to you in the passage :) Which of the following is LEAST likely to occur in a muscle fiber
