QID: 1385 L 3 D Select Answer to see Preferred Response What type of movement is used in isometric exercises?Isometric exercises are tightening (contractions) of a specific muscle or group of muscles. During isometric exercises, the muscle doesn't noticeably change length. The affected joint also doesn't move. Isometric exercises help maintain strength.
What type of movement is used in isometric exercises quizlet?There is no movement in isometric exercises. For maximum strength gains, how long should you hold an isometric contraction maximally?
What is the best description for isometric exercise quizlet?What is the best description for isometric exercise? Applying force without a change in the length of the muscle.
Why isometric exercises?Isometric exercises place tension on particular muscles without moving the surrounding joints. By applying constant tension to the muscles, isometric exercises can be useful for improving physical endurance and posture by strengthening and stabilizing the muscles.
