Question

While performing Running, Jumping and Calisthenics movements can be seen directly those result into toned muscles and increased muscle length, These are known as

• A. Isometric Exercises
• B. Isotonic Exercises
• C. Isokinetic Exercises
• D. Anaerobic Exercises

Hint:

Muscle length changes with movement in these exercises.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
The question describes movements like running, jumping and calisthenics. In these the muscle length changes and the muscles get toned. We need the name of this type of exercise.


Step 2: Key idea:
In isotonic exercises the muscle tension stays the same while the muscle shortens or lengthens, so a visible movement takes place. Running, jumping and calisthenics are common examples.


Step 3: Check each option:
Option 1, isometric exercises: the muscle contracts but its length does not change and no movement is seen. So it is wrong.
Option 2, isotonic exercises: movement with a change in muscle length, which fits.
Option 3, isokinetic exercises: movement at a constant speed on special machines. Running and jumping are not done this way. So it is wrong.
Option 4, anaerobic exercises: this names an energy system that works without oxygen, not a type of muscle contraction. So it is wrong.


Final Answer:
The exercises are isotonic exercises. \[\boxed{\text{Option 2: Isotonic Exercises}}\]
