Answer 2

Answer:

Isometric exercise is a type of exercise in which muscle length is constant.

Therefore, option (a) is correct.

Explanation:

Muscle contraction has two types: Isotonic and Isometric.

• Isotonic contractions in which muscles become longer or against  tension and resistance remains the same.
• Isometric contractions in which the muscle length remains constant when tension increases.

Isometric exercises:-

• There is no muscles shortening or lengthening involve in Isometric exercise.
• The joints don't move and  the muscles do not change size during isometric exercises.
• Someone will typically hold the isometric contraction  for several seconds or minutes.
• Some isometric exercises involve to develop tension by holding the body in a specific position or some involve holding weights.
• Holding the muscle contraction creates metabolic stress on the muscle  and fill the muscles tissues with blood. Muscle contraction helps to improve the strength of muscles.
