8. What is the resultant muscle force required to maintain the leg in this position ?

17. Passive insufficiency can result in resistance to or a loss of range of motion. Which of the below are scenarios consistent with this principle?

24. If the shoulder is flexed to 90 degrees and the elbow is fully flexed and held statically, more EMG signal is recorded from the long head of the biceps as compared to when the shoulder is flexed to 90 degrees and the elbow is extended. This indicates:

20. If a subject cannot generate adequate muscle force to rotate the elbow and lift the forearm against gravity

27. People may be more susceptible to spinal disc herniation later in the day after having been in an upright posture for prolonged periods. Which of the following are consistent with this theory and with principles of tissue mechanics:

For the following 2 questions, use the equations you developed in B above and account for the proper sign. Show all steps of your work. Use 4 decimal places for sin, cos, or distance values, and 1 decimal for final force and torque values. The moment arms are .0087 m for the muscle, and .2819 m for the weight of the limb.

5. Based on your answer to question 4, what is the subsequent effect of this change on the lumbar spine joint compressive force?

14. Which of the following could result from active insufficiency

4. What would be the effect on the muscle force required if the arms were held across the chest rather than behind the head during a sit-up?
