NASM CES TEST 1 Practice Questions with 100% Correct Answers.

What percentage of the population is estimated to be obese? Correct Answer 33.8% More than one third of all work-related injuries involve the trunk, and of these, Correct Answer more than 60% involve the low back. What does eccentric deceleration mean? Correct Answer When a resistive force overcomes a muscle's developed tension What percentage of ACL injuries are estimated to be non-contact? Correct Answer 70-75% Subsystems transfers forces that are summated from the muscle's transverse plane orientation to propulsion in the sagittal plane, as occurs during walking or running? Correct Answer Posterior Oblique Subsystem Which adductor muscle has fibers that can concentrically accelerate extension of the femur? Correct Answer Adductor magnus Which muscle is the primary frontal plane stabilizer of the knee complex? Correct Answer Gluteus medius Which muscle concentrically produces extension of the hip, and a posterior tilt of the pelvis? Correct Answer Gluteus maximus Which muscle eccentrically decelerates humeral external rotation, abduction, and flexion? Correct Answer Teres major What is the name of the hyperbolic relationship which shows that as 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 What system is predominantly responsible for movement and consists of more superficial musculature that originates from the pelvis to the rib cage, the lower extremities, or both? Correct Answer Global muscular system The gluteus medius, tensor fascia latae, adductor complex, and quadratus lumborum comprise the Correct Answer Lateral subsystem
