Which type of muscle contraction occurs when a muscle generates force while lengthening under load?
Answer: Eccentric contraction
An eccentric contraction occurs when the muscle lengthens while producing force, such as lowering a weight slowly.
What is the primary role of the rotator cuff muscles during shoulder abduction?
Answer: Stabilizing the humeral head in the glenoid fossa
The rotator cuff muscles act as dynamic stabilizers, keeping the humeral head centered in the glenoid fossa during movement.
Which plane of motion describes a movement that divides the body into front and back halves?
Answer: Frontal plane
The frontal (coronal) plane divides the body into anterior and posterior portions and includes movements like abduction and adduction.
During normal gait, which phase occurs when both feet are in contact with the ground simultaneously?
Answer: Double support phase
The double support phase occurs briefly during walking when weight is transferred from one foot to the other with both feet on the ground.
What type of lever system is represented by the calf muscles performing a heel raise?
Answer: Second-class lever
A heel raise uses a second-class lever where the resistance (body weight) is between the fulcrum (toes) and the effort (calf muscles at the heel).
Which biomechanical principle explains why wider stances provide greater stability during massage techniques?
Answer: Larger base of support lowers the center of gravity relative to the base
A wider stance increases the base of support, making it easier to keep the center of gravity within that base for better stability.
