Question

1. what type of exercise is this?

a. isokinetic movement
b. dynamic movement
c. isotonic movement
d. static movement

1. what type of muscle contraction is this?

a. isokinetic
b. dynamic
c. isometric
d. isotonic

Explanation:

Question 17

The exercise shown (wall sit) involves holding a static position with no joint movement, which is a static movement. Isokinetic (A) involves constant speed, dynamic (B) has movement, isotonic (C) has muscle length change with movement. So static movement (D) matches.

In a wall sit, muscles contract without changing length (joint angle doesn't change), which is isometric contraction. Isokinetic (A) is constant speed, dynamic (B) implies movement, isotonic (D) has length change. So isometric (C) is correct.

Answer:

D. Static movement
