NASM CES Practice Exam Questions with Complete Solutions

Population is obese Correct Answer 33% Which adductor muscle has fibers that can concentrically accelerate extension of the femur? Correct Answer Adductor magnus Which muscle eccentrically decelerates hip adduction, and internal rotation? Correct Answer Gluteus medius (posterior fibers) Which muscle is the primary frontal plane stabilizer of the knee complex? Correct Answer Gluteus medius Which muscle eccentrically decelerates humeral external rotation, abduction, and flexion? Correct Answer Teres major Which muscle concentrically produces extension of the hip, and a posterior tilt of the pelvis? Correct Answer Gluteus maximus Which muscle decelerates humeral external rotation, abduction, and flexion? Correct Answer Teres major Which muscle concentrically accelerates external rotation of the humerus? Correct Answer Teres minor Which combination of joint motions occur at the foot/ankle during lower body pronation? Correct Answer dorsiflexion, eversion, abduction During resistance training, which action by the muscle(s) prevents weight/resistance from accelerating in an uncontrolled manner as a result of gravitational force? Correct Answer Eccentric What is the name of the hyperbolic relationship which shows that the velocity of a concentric contraction increases, the developed tension decreases? Correct Answer force-velocity curve Which subsystem consists of force-couple relationships that primarily control the pelvis and femur in the frontal plane during single-leg functional movements such as gait, lunges, or stair climbing? Correct Answer lateral subsystem More than one-third of work-related injuries involve the trunk, and of these Correct Answer more than 60% involve the low back
