What is the term for the angle formed at a joint between two body segments?
Answer: Joint angle
Joint angle is the measure of the angle between two body segments at the articulation and is a key variable in biomechanical analysis.
Which muscle is primarily responsible for shoulder abduction between 0–90 degrees?
Answer: Deltoid
The middle deltoid is the primary abductor of the shoulder from 0 to approximately 90 degrees of elevation.
Which of the following best describes 'torque' in exercise biomechanics?
Answer: Rotational force about a joint axis
Torque is the rotational force produced about a joint axis and equals force multiplied by the perpendicular moment arm.
The gastrocnemius crosses which two joints?
Answer: Knee and ankle
The gastrocnemius is a two-joint muscle that crosses both the knee joint and the ankle joint.
Which term describes the muscle that assists the prime mover without being the primary force producer?
Answer: Synergist
A synergist assists the agonist in producing movement but is not the primary muscle responsible for the action.
Which bony landmark is used as a reference point for measuring hip flexion range of motion?
Answer: Greater trochanter
The greater trochanter of the femur is the standard bony landmark used as the axis of rotation when measuring hip flexion with a goniometer.
