1. In addition to inadequate hamstring muscle strength, which of the following is a primary risk factor for hamstring strain?

A. Altered knee kinematics B. Impaired knee joint proprioception C. Poor hamstring flexibility D. All of the above are primary risk factors for hamstring strain

2. To prevent hamstring strain, traditional stretching exercise such as static, ballistic, or proprioceptive neuromuscular facilitation stretching is recommended prior to exercise or sporting activities.

A. True B. False

3. Which of the following is a common test to examine the hamstring muscle flexibility?

A. The FABER test B. Patrick’s test C. The passive straight leg raise test D. Schober’s test

4. Muscle contraction during the lengthened or stretched state can alter all of the following, except for:

A. Angular peak torque B. Force generation C. Optimal sarcomere length D. Optimal joint angle

5. The findings of this study showed that there is an increase in _____ following DS and LEC.

A. Flexibility B. ROM C. Muscle strength D. Joint position senses

6. Stretching improves hamstring ROM by improving the muscle compliance.

A. A change in stretch tolerance B. The passive properties of muscle C. Both a change in stretch tolerance and the passive properties of muscle D. Neither a change in stretch tolerance nor the passive properties of muscle

8. Which of the following impaired hamstring muscle performance?

A. Jogging only B. DS C. LEC D. All of the above impaired hamstring muscle performance

9. Decreased eccentric peak torque takes place following LEC.
