B) Increasing the resistance. 
C) Increasing the speed of performance. 
D) Increasing the duration of the exercise.

Question 8

Your patient is nearing the end of his rehabilitation for return to sport and is performing more of his program independently at home.As you are providing education regarding precautions and recognizing signs and symptoms, you discuss how much recovery time he should allow between sessions of high-intensity plyometric drills.Based on research, how much time do you suggest?

Accepted Answer

A) 15-30 minutes 
B) 24 hours 
C) 48-72 hours 
D) 8-12 hours

Question 9

For an individual to be able to execute functional activities, it is necessary to have the ability to maintain the position of the body in equilibrium within the environment.This state of equilibrium is called:

Accepted Answer

A) Power. 
B) Endurance. 
C) Postural stability. 
D) Strength.

Question 10

Moving and planting activities, in which the patient is required to move, change position, and then hold the position (freeze) are most appropriate for a patient returning to which activity/function?

Accepted Answer

A) An usher at a sporting event who has to stand for long periods 
B) A traveler who needs to use escalators routinely both with luggage and without 
C) A receptionist who frequently transitions from sit to stand and escorts individuals to their meetings 
D) A tour guide who walks for long distances on cobblestones or other uneven surfaces

Question 11

You have been treating a 25-year-old soccer player, who has been recovering from hip bursitis.She is pain free and performing routine activities of daily living, walking and running without symptoms.She is now progressing to a phase of advanced functional training to prepare her for the quick turns, starts and stops, and dynamic single leg stances when kicking the soccer ball.Which of the following activities would be appropriate to include in her program to specifically achieve these functional tasks?

Accepted Answer

A) Open-chain knee extension on a resistance machine after establishing her 1 Rep Max 
B) Single leg stance on a stable surface, increasing the duration to 90 seconds 
C) Zigzag forward hopping 
D) Pushing and pulling heavy objects

Question 12

Each of the following describes the concept and/or mechanism of plyometrics except:

Accepted Answer

A) High-velocity eccentric to concentric muscle loading. 
B) Stretch-strengthening drills. 
C) Stretch-lengthening drills. 
D) Reactive neuromuscular training.

Question 13

When designing an exercise program to return a patient to his/her prior functional level, each of the following guidelines is true except:

Accepted Answer

A) Proximal stability is a requirement for controlled distal mobility. 
B) Coordinated segmental and global stability of the spine is needed for execution of functional tasks with safe body mechanics. 
C) Stability of each joint is necessary for effective function of the extremities. 
D) Exercises for strength and power should precede balance and stability exercises.

Question 14

As you develop progressions of exercise programs for varied patients, which of the following describes the appropriate use of plyometric drills?

Accepted Answer

A) Pediatric programs should include plyometric drills because they are fun to perform and will engage the patient in functional activities. 
B) Patients with unstable joints should perform plyometric drills early in the course of therapy to challenge firing of antagonistic muscle groups. 
C) Every patient on a strengthening program should progress to plyometric drills during the return-to-function phase of rehabilitation. 
D) Patients in advanced phases of rehabilitation should be trained to return to high-demand functional activities and sports

Question 15

Another term for the concept of plyometric training is reactive neuromuscular training.At the cellular and neuromuscular receptor level, which of the following describes the mechanism of plyometrics?

Accepted Answer

A) The eccentric contraction stimulates and activates the monosynaptic stretch reflex in the muscle and so prepares the muscle for a concentric contraction. 
B) The concentric contraction (stretch shortening drill) builds power that is released in the eccentric (lengthening drill) that follows. 
C) A slow eccentric (lengthening) contraction stretches the muscle spindle, transmitting a more powerful concentric (shortening) contraction. 
D) Quick eccentric loads expend energy that is then transmitted to the muscle spindle, resulting in muscular hypertrophy and increased power.
