Question

Mark each statement as either True (T) or False (F). If the statement is false, change the word that is in bold to make the statement true. Scoring: 1 point for answering T/F correctly and 1 point for correcting the false statement correctly. If you mark an answer True that is False you will lose both points. If you mark an answer False that is True you will lose one point. 55) During a level run the horizontal component of the ground reaction force has a positive and a negative component. 56) If the force produced by a muscle is equal to 10 Newtons and the muscle moment is 5 cm, the torque produced by this muscle is 500 Newton*cm. 57) During running, potential and kinetic energy are out of phase. 58) If the gear ratio, R/r, of a muscle at a joint is large the muscle is designed to produce large changes in joint angle not large muscle torques. 59) When your foot is plantarflexed and you are standing on your toes the gastocnemius at the ankle is acting as a second class lever. 60) A pinnate muscle will have a smaller physiological cross sectional area than a parallel fibered muscle of the same mass. 61) Running is modeled as an inverted pendulum where elastic energy is stored in tendons and ligaments. 62) Fast glycolytic fibers fatigue rapidly and have a large diameter.

Explanation / Answer

Mark each statement as either True (T) or False (F). If the statement is false, change the word that is in bold to make the statement true. Scoring: 1 point for answering T/F correctly and 1 point for correcting the false statement correctly. If you mark an answer True that is False you will lose both points. If you mark an answer False that is True you will lose one point.

55) During a level run the horizontal component of the ground reaction force has a positive and a negative component.

True

56) If the force produced by a muscle is equal to 10 Newtons and the muscle moment is 5 cm, the torque produced by this muscle is 500 Newton*cm.

True

57) During running, potential and kinetic energy are out of phase.

False

58) If the gear ratio, R/r, of a muscle at a joint is large the muscle is designed to produce large changes in joint angle not large muscle torques.

False

59) When your foot is plantarflexed and you are standing on your toes the gastocnemius at the ankle is acting as a second class lever.

True

60) A pinnate muscle will have a smaller physiological cross sectional area than a parallel fibered muscle of the same mass.

True

61) Running is modeled as an inverted pendulum where elastic energy is stored in tendons and ligaments.

True

62) Fast glycolytic fibers fatigue rapidly and have a large diameter.

True
